Then go to ‘fotista’ directory

teddy@teddy-K43SJ:~/Documents/works/laravel$ cd fotista/

1	teddy@teddy-K43SJ:~/Documents/works/laravel$ cd fotista/

Install required components:

teddy@teddy-K43SJ:~/Documents/works/laravel/fotista$ composer install

1

teddy@teddy-K43SJ:~/Documents/works/laravel/fotista$ composer install
Create a database ‘auction’ via phpmyadmin
Import the sql script ‘auction-20140823-0211.sql’ in ‘/sql archive/’ dir (extract the zip first).

Set a few configuration settings in /app/config/app.php like

'url' => 'http://localhost/works/laravel/auction/public',

1	'url' => 'http://localhost/works/laravel/auction/public',

and the database (Laravel 4 dont use .env file to store the database setting) in /app/config/database.php

'mysql' => array(
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'database'  => 'auction',
    'username'  => 'root',
    'password'  => 'XXX',
    'charset'   => 'utf8',
    'collation' => 'utf8_unicode_ci',
    'prefix'    => '',
),

'mysql' => array(

'driver' => 'mysql',

'host' => 'localhost',

'database' => 'auction',

'username' => 'root',

'password' => 'XXX',

'charset' => 'utf8',

'collation' => 'utf8_unicode_ci',

'prefix' => '',

generate the new key

php artisan key:generate

1

php artisan key:generate
set file permission to 777 for /app/storage

teddy@teddy-K43SJ:~/Documents/works/laravel/fotista$ sudo chmod -R 777 app/storage/

1

teddy@teddy-K43SJ:~/Documents/works/laravel/fotista$ sudo chmod -R 777 app/storage/
Make some update on the database, especially for table ‘images’, I need to remove and replace ‘http:\\/\\/localhost\\/auction\\/public\\/uploads\\/’ in ‘images’ field because I just need the image name. No need the url. With this I can show the product image and the thumbnails. I did the replace in my text editor geany instead of on phpmyadmin because it’s easier to do it in geany. Also modified a few files to display the images and the thumbnails properly:
in /app/views/home.blade.php, replace ‘$product -> thumbnail’ to ‘{{ URL::to( ‘uploads/’ . $product -> thumbnail) }}’ (TWICE) like this

<img src="{{ URL::to( 'uploads/' . $product -> thumbnail) }}" />

1

<img src="{{ URL::to( 'uploads/' . $product -> thumbnail) }}" />

Also the same for /app/views/store.blade.php and /app/views/auction.blade.php. Same also for /app/views/product.blade.php BUT at ‘$product -> large’ like this:

<img src="{{ URL::to( 'uploads/' . $product -> large) }}" />

1

<img src="{{ URL::to( 'uploads/' . $product -> large) }}" />

Also the same for ‘admin’ page: /app/views/admin/products.blade.php, /app/views/admin/product.blade.php, /app/views/admin/auction.blade.php.
Open it http://localhost/works/laravel/fotista/public/The admin page http://localhost/works/laravel/fotista/public/admin/
http://localhost/works/laravel/fotista/public/admin/products
SOME ERRORS & SOLUTION:
The first time, I got this error:

Error in exception handler.

1

Error in exception handler.

SOLUTION: It because I forgot to set the file permission at #7 (ref:http://stackoverflow.com/questions/24982598/laravel-error-in-exception-handler)
NOTE: To get better debug environment, I need to set ‘debug’ to ‘true’ in /app/config/app.php!

'debug' => true,

1

'debug' => true,

After that I got another error:

Whoops, looks like something went wrong.

1

Whoops, looks like something went wrong.

SOLUTION: That because I forgot to set a new key like at #6 (ref:http://laravel.io/forum/04-22-2014-whoops-looks-like-something-went-wrong-with-new-installation)
NOTE: For laravel 4, No need to create .env file like laravel 5
Then I got another error:

Access denied for user ''@'localhost' (using password: NO)

1

Access denied for user ''@'localhost' (using password: NO)

SOLUTION: I forgot to set the database setting in /app/config/database.php like at #5 (ref: http://laravel.io/forum/07-02-2014-sqlstatehy000-1044-access-denied-for-user-localhost-to-database-forge?page=1)

UNSOLVED ERROR:
When I tried to click ‘Auction started click here to open it’. It didn’t work. It did open a new page but do nothing. Just printed ‘Loading…’. From the console, it’s looking for a file in http://localhost/works/laravel/fotista/public/api/auction BUT THERE IS NO /public/api/auction DIR AVAILABLE!
The controller responsible for this is /app/controller/AuctionController.php, The view is /app/views/auction-app.blade.php and the javascript file in /public/js/auction-app.js
HOW TO MAKE THE AUCTION FULLY WORKS???? ESPECIALLY THE ANGULAR JS ‘auction-app.js’???
PLS TRY THIS GITHUB: https://github.com/yervand951/angular-auction
CONVERT TO LARAVEL 5 ???? ref: https://mattstauffer.co/blog/upgrading-from-laravel-4-to-laravel-5 and https://laravel.com/docs/5.0/upgrade.

Laravel Quiz

source: https://github.com/SAIBA0011/laravel-quiz

Description:

Laravel-Quiz functionality

Create a new quiz
Create quiz questions — single & multi Select
show quiz questions
Create quiz question options — Pending..
To be implemented

Finish quiz question options.
Change question position.
Change question option position.
Randomize question order on display page.
Track user attempts per quiz.
Allow user to take quiz.
allow user to complete quiz.
show quiz results on complete.

Installation:

Create a new laravel project:

composer create-project --prefer-dist laravel/laravel laravel-quiz

1

composer create-project --prefer-dist laravel/laravel laravel-quiz
Download the app from https://github.com/SAIBA0011/laravel-quiz. It’s better to donwload in zip file then extract the content in /works/laravel/quiz/ directory. Overwrite the existing files and directories.
Install the laravel component required:

composer install

1

composer install
Create a new database ‘laravel_quiz’ by phpmyadmin

Use ‘php artisan migrate’ to create the tables.
NOTE: I got this error when trying to do ‘migrate’
“teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-quiz$ php artisan migrate
Migration table created successfully.[Illuminate\Database\QueryException]
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error i
n your SQL syntax; check the manual that corresponds to your MySQL server v
ersion for the right syntax to use near ‘) on delete cascade’ at line 1 (SQ
L: alter table quiz_results add constraint quiz_results_user_id_foreign
foreign key (user_id) references users () on delete cascade)
[PDOException]
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error i
n your SQL syntax; check the manual that corresponds to your MySQL server v
ersion for the right syntax to use near ‘) on delete cascade’ at line 1 ”
SOLUTION: At first, I did like in the articles http://stackoverflow.com/questions/26820788/add-on-delete-cascade-to-existing-column-in-laravel and http://stackoverflow.com/questions/28167329/laravel-migration-remove-ondeletecascade-from-existing-foreign-key on ‘2016_10_24_101046_create_quiz_results_table.php’ in /database/migrations/ directory BUT SOMEHOW IT DIDN’T WORK

$table->dropForeign('quiz_results_user_id_foreign');
$table->foreign('user_id')->reference('id')->on('users')->onDelete('cascade');
//$table->foreign('user_id')->reference('id')->on('users');

$table->dropForeign('quiz_results_quiz_id_foreign');
$table->foreign('quiz_id')->reference('id')->on('quiz')->onDelete('cascade');
//$table->foreign('quiz_id')->reference('id')->on('quiz');

$table->dropForeign('quiz_results_user_id_foreign');

$table->foreign('user_id')->reference('id')->on('users')->onDelete('cascade');

//$table->foreign('user_id')->reference('id')->on('users');

$table->dropForeign('quiz_results_quiz_id_foreign');

$table->foreign('quiz_id')->reference('id')->on('quiz')->onDelete('cascade');

//$table->foreign('quiz_id')->reference('id')->on('quiz');

SO I JUST COMMENT THE ‘onDelete’ COMMAND

//$table->foreign('user_id')->reference('id')->on('users')->onDelete('cascade');
//$table->foreign('quiz_id')->reference('id')->on('quiz')->onDelete('cascade');

1 2	//$table->foreign('user_id')->reference('id')->on('users')->onDelete('cascade'); //$table->foreign('quiz_id')->reference('id')->on('quiz')->onDelete('cascade');

THEN THE MIGRATIONS RUN WELL.

generate the new key

php artisan key:generate

1

php artisan key:generate

Install npm modules and gulp

npm install

1	npm install

BUT SOMEHOW I GOT THIS ERROR ON ‘gulp’

/home/teddy/Documents/works/laravel/laravel-quiz/node_modules/laravel-elixir-webpack-official/node_modules/webpack/node_modules/loader-runner/lib/loadLoader.js:35

throw new Error("Module '" + loader.path + "' is not a loader (must have normal or pitch function)");

Error: Module '/home/teddy/Documents/works/laravel/laravel-quiz/node_modules/buble/dist/buble.umd.js' is not a loader (must have normal or pitch function)

I ALSO TRIED (DONT DO THIS BECAUSE I BROKE THE ENVIRONMENT BINDING!)

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

sudo npm cache clean -f

sudo npm install -g n

sudo n stable

BECAUSE OF THIS I GOT A HARDTIME AND SPENT MANY ERRORS TO FIX IT (http://stackoverflow.com/questions/37324519/node-sass-does-not-yet-support-your-current-environment-linux-64-bit-with-false) THROUGH THIS:

sudo npm rebuild node-sass

1	sudo npm rebuild node-sass

BUT THE ERROR STILL PERSIST (ON GULP)! DONT KNOW HOW TO FIX IT!!!
I READ gulpfile.js IN ‘laravel-quiz’ PROJECT DIFFERENT WITH IN ‘quiz’ PROJECT. THEREFORE ‘laravel-quiz’ PROJECT USE VUE!!!

Test it live (http://localhost:8000)IT RUN WELL
Errors & Solutions:
When I want to see the quiz result by submitting the answer (http://localhost:8000/second-quiz/submit), I got this error:
“ErrorException in QuizResultsController.php line 25:
Trying to get property of non-object”
SOLUTION: This is because I didn’t login first. Use http://localhost:8000/home to login/register (I’ve registered with email: ‘advcha@yahoo.com’ and password: ‘satria’) then take the quiz again and answer the above question. Then the result would be showed up like this:
Others samples for online quiz:
http://practice.cappassessments.com/Nrt/NrtPage.html (Shows time to answer question, can drag up or down the answer options, not only can pick the answer, but also can type the answer). There is a job application in upwork for this kind of online quiz: https://www.upwork.com/jobs/_~01d2316bc1f3c2cb84/.

Quiz

source: https://github.com/sms516/quiz
online: http://dojang.nz/

Installation:

Create a new laravel project:

composer create-project --prefer-dist laravel/laravel quiz

1

composer create-project --prefer-dist laravel/laravel quiz
Download the app from https://github.com/sms516/quiz. It’s better to donwload in zip file then extract the content in /works/laravel/quiz/ directory. Overwrite the existing files and directories.
Install the laravel component required:

composer install

1

composer install
Import the database file (DB_SETUP.sql) along with the github.
NOTE: ‘quiz_details’ table can’t be created because the field type ‘datetime CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP’ for ‘updated_at’ can’t be used. So replace ‘datetime’ with ‘timestamp’
Set the file/folder permission for ‘storage’

teddy@teddy-K43SJ:~/Documents/works/laravel/quiz$ sudo chmod -R 777 storage/

1

teddy@teddy-K43SJ:~/Documents/works/laravel/quiz$ sudo chmod -R 777 storage/
Test it live (http://localhost:8000/admin)

teddy@teddy-K43SJ:~/Documents/works/laravel/quiz$ php5.6 artisan serve

1

teddy@teddy-K43SJ:~/Documents/works/laravel/quiz$ php5.6 artisan serve

WORKING!!!CAN’T SHOW http://localhost:8000/admin BUT CAN SHOW http://localhost:8000/admin/quiz/questionsNOTE: Check the routes in /app/Http/routes.php. The routes are very limited! NO ROUTE FOR ADMIN???

I found gulpfile.js in the root of the website, so I think I need to use npm and gulp to compile the saas:
Use ‘npm install’ to install required modules

I DONT KNOW HOW TO DO NEXT OR HOW THE NPM AND GULP AFFECT THE WEBSITE! NEED TO LEARN ABOUT THESE!!!

On the homepage ‘http://localhost:8000’, I clicked ‘Start Quiz’ button but I got NOT FOUND error (ajax error) at the chrome console. I found it is triggered by ‘onclick=”startQuiz()”‘ in /resources/views/quiz/view.blade.php and the javascript command in /public/js/functions.js. I NEED TO MODIFY A FEW SETTING IN functions.js file! First replace the ‘base_dir’ variable like below:

//var base_dir='http://localhost/quiz/public/ajax/';
var base_dir='http://localhost/works/laravel/quiz/public/ajax/';

1 2	//var base_dir='http://localhost/quiz/public/ajax/'; var base_dir='http://localhost/works/laravel/quiz/public/ajax/';

FROM NOW ON, I HAVE TO USE ‘http://localhost/works/laravel/quiz/public/’ INSTEAD OF ‘http://localhost:8000’! FOR HOMEPAGE AND ‘http://localhost/works/laravel/quiz/public/admin/quiz/questions’ FOR ADMIN PAGE!
NOW THE AJAX IS WORKING!! ‘Start Quiz’ button IS WORKING!
Another errors detected:

Sometimes I got unknow error when trying to edit the question (http://localhost/works/laravel/quiz/public/admin/quiz/question/376).
Solution: I need to put ‘ini_set(‘display_errors’,1);’ in /app/Http/routes.php to enable to debug the errors. It seems the ‘storage’ directory HAS NOT BEEN SET THE PERMISSION. So make sure the step #5 is executed first!

Improvements:
Many links in the admin page can’t be opened or don’t have the correct routes. Here I want to fix or develop the links.
Club Admin (http://localhost/works/laravel/quiz/public/admin/club)
Add a new route in /app/Http/routes.php

Route::get('admin/club', 'ClubController@viewClubs');

1	Route::get('admin/club', 'ClubController@viewClubs');

Create a new controller ‘ClubController.php’ in /app/Http/Controllers/

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\models\Club;

class ClubController extends Controller
{
    public function viewClubs(Request $request)
    {
        $data=array();
        $data['title']='Clubs';
        $data['clubs']=Club::get();
        return view('club.view',$data);
        
    } 
}

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\models\Club;

class ClubController extends Controller

{

public function viewClubs(Request $request)

{

$data=array();

$data['title']='Clubs';

$data['clubs']=Club::get();

return view('club.view',$data);

}

The ‘Club’ model is already exist in /app/models/ directory! Here we want to show all the club in our database!
The data would be showed up by /resources/views/club/view.blade.php like this:

Add/Save New Club (http://localhost/works/laravel/quiz/public/admin/club/add)
Add two new routes in /app/Http/routes.php

OK. then make a test at http://localhost/works/laravel/quiz/public/admin/club/add.

I got this club sample from Kumgang Tae Kwon Do website. Then save the data by clicking ‘Add Club’. Here is the working result:

Edit/Save Club (http://localhost/works/laravel/quiz/public/admin/club/edit/4)
First I need to put ‘Edit’ link on the club admin page (http://localhost/works/laravel/quiz/public/admin/club). Modify ‘view.blade.php’ in /resources/views/club/ directory. Modify the header table to show/hide the needed field (add class ‘all’ to show and ‘none’ to hide)

...
<table id="clubTable" class="display responsive nowrap" cellspacing="0" width="100%">
    <thead>
        <tr>
            <th class="all">Name</th>
            <th class="all">Short Name</th>
            <th class="all">Email</th>
            <th class="all">Phone</th>
            <th class="none">Location</th>
            <th class="all"></th>
        </tr>
    </thead>
...

...

<thead>

<tr>

<th class="all">Short Name</th>

<th class="all">Email</th>

<th class="all">Phone</th>

<th class="none">Location</th>

</tr>

</thead>

...

Then arrange the field width by defining the columns (‘columnDefs’) like this:

$(document).ready(function() {
    $('#clubTable').dataTable({
        responsive: true,
        "dom": 'f<t>p',
        "columnDefs": [
            { "width": "10%", "targets": 1 },
            { "width": "10%", "targets": 2 },
            { "width": "10%", "targets": 3 },
            { "width": "10%", "targets": 5 }
          ]
    });
});

$(document).ready(function() {

$('#clubTable').dataTable({

responsive: true,

"dom": 'f<t>p',

"columnDefs": [

{ "width": "10%", "targets": 1 },

{ "width": "10%", "targets": 2 },

{ "width": "10%", "targets": 3 },

{ "width": "10%", "targets": 5 }

]

});

So here is the new looks

To make the ‘Edit’ links work, add two new routes in /app/Http/routes.php

Route::get('admin/club/edit/{club_id}', 'ClubController@editClub');
Route::post('admin/club/edit/{club_id}', 'ClubController@saveEditClub');

1 2	Route::get('admin/club/edit/{club_id}', 'ClubController@editClub'); Route::post('admin/club/edit/{club_id}', 'ClubController@saveEditClub');

OK. Now the Club admin can be used properly.

HOW TO DELETE CLUB???

Sistem Informasi Sekolah (SIS)

Source: https://github.com/balitax/SI-Sekolah-L5

Installation: (the most steps is pretty same with Laravel Blog)

Create a new laravel project:

composer create-project --prefer-dist laravel/laravel sis

1

composer create-project --prefer-dist laravel/laravel sis
Download the app from https://github.com/balitax/SI-Sekolah-L5. It’s better to donwload in zip file then extract the content in /works/laravel/sis/ directory. Overwrite the existing files and directories.
Install the laravel component required:

composer install

1

composer install
edit .env file and fill the database account (DB name is sis)
Import the database file (database_sekolah.sql) along with the github.
Note: authentication scaffolding NOT RUN HERE! ERROR BUT NO PROBLEM
Use ‘migration’ to add some new tables into the new database

php artisan migrate

1

php artisan migrate
Dont forget to set the file permission in /public/ directory if we want to upload an image into it

teddy@teddy-K43SJ:~/Documents/works/laravel/sis$ sudo chmod -R 777 public/

1

teddy@teddy-K43SJ:~/Documents/works/laravel/sis$ sudo chmod -R 777 public/
I found some errors when tried it for the first time. http://localhost:8000/login IS WORKING but CAN’T LOGIN. THE USER TABLE IN ‘tbl_kepegawaian’. BECAUSE I DONT KNOW THE ‘admin’ PASSWORD, I NEED TO UPDATE ‘password’ FIELD WITH ‘$2y$10$eWW.aZOeruiS1VEO0ghKHu7A7UoQcj2tVmLIcnw6JnrcsiljuOmYK’ –> ‘satria’. SO the ‘admin’ password is ‘satria’. NOW I CAN GO INTO THE ADMIN PAGE (dashboard, data sekolah, data siswa, galeri foto, absensi siswa, data pegawai, etc).
THERE ARE SO MANY ERRORS (I CAN’T GO INTO THE WEBSITE ROOT OR http://localhost:8000/ BUT ONLY CAN GO TO http://localhost:8000/admin). ANYWAY IT’S GOOD AND I CAN SEE THE SCREEN!
NOTES: pls study the routes in /app/Http/routes.php !

SOMETHING IS NEEDED TO FIX SOME ERRORS:

Error when I want to acces the root http://localhost:8000/
“FatalErrorException in Handler.php line 25:
Uncaught TypeError: Argument 1 passed to App\Exceptions\Handler::report() must be an instance of Exception, instance of Error given, called in /home/teddy/Documents/works/laravel/sis/vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/HandleExceptions.php on line 73 and defined in /home/teddy/Documents/works/laravel/sis/app/Exceptions/Handler.php:25
Stack trace:
#0 /home/teddy/Documents/works/laravel/sis/vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/HandleExceptions.php(73): App\Exceptions\Handler->report(Object(Error))
#1 [internal function]: Illuminate\Foundation\Bootstrap\HandleExceptions->handleException(Object(Error))
#2 {main}
thrown”
SOLUTION: The error because I use PHP 7 (CLI) when I started the server (‘php artisan serve’). ref: http://stackoverflow.com/questions/36983734/laravel-fatalerrorexception-in-handler-php-line-25. So use php 5.6 instead when starting the server like this:

php5.6 artisan serve

1

php5.6 artisan serve

Another error when accessing the root website:
“FatalErrorException in FrontController.php line 42:
Class ‘App\Models\Banner’ not found”
SOLUTION: In /app/Http/Controllers/FrontController.php, comment a few lines:

//$this->data['banner']           = Models\Banner::where('id',1)->first();
//$this->data['link']             = Models\Link::orderBy('id','desc')->limit(5)->get();
//$this->data['publikasi']        = Models\Publikasi::orderBy('id','desc')->limit(3)->get();

//$this->data['banner'] = Models\Banner::where('id',1)->first();

//$this->data['link'] = Models\Link::orderBy('id','desc')->limit(5)->get();

//$this->data['publikasi'] = Models\Publikasi::orderBy('id','desc')->limit(3)->get();

Because there is models available for them.
Also in ‘index’ function, replace ‘bappeda’ with ‘web’

public function index() {
    //return view('bappeda.home', $this->data);
    return view('web.home', $this->data);
}

public function index() {

//return view('bappeda.home', $this->data);

return view('web.home', $this->data);

}

Now, the root/front website can be displayed but the website can’t be loaded. User need to upload the logo manually from the admin page -> Setting (http://localhost:8000/admin/setting). But when I saved the input, This error is appeared:
“QueryException in Connection.php line 624:
SQLSTATE[42S22]: Column not found: 1054 Unknown column ‘peta_latitude’ in ‘field list’ (SQL: update tbl_setting set title_web = Sekolah Ku, desc_web = Sekolah Ku, key_web = sekolah, logo = lapVa94436orMdu892YPf3uSj931XM.png, facebook = , twitter = , gplus = , peta_latitude = , peta_longitude = , alamat = , no_telp = , no_fax = , email = where id_setting = 1)”
SOLUTION: Modify tbl_setting in the database, then add these new fields: peta_latitude varchar(25), peta_longitude varchar(25), alamat text, no_telp varchar(25), no_fax varchar(25) and email varchar(25).
Now the website logo can be displayed

When I clicked one of the news (berita) like http://localhost:8000/baca/berita/2011-lembaga-pemerintah-sudah-harus-cicipi-open-source, I got this error:
“InvalidArgumentException in FileViewFinder.php line 140:
View [bappeda.berita_detail] not found.”
SOLUTION: in /app/Http/Controllers/FrontController.php, Modify ‘berita’ function and replace ‘bappeda’ with ‘web’ and ‘berita_detail’ with ‘beritadetail’

public function berita($slug) {
    $berita_detail              = Models\Berita::where('slug_berita',$slug)->first();
    $this->data['title']        = $berita_detail->judul_berita;
    $this->data['beritalist']   = $berita_detail;
    $this->data['desc']         = substr($berita_detail->isi,0,200).'...';
    $this->data['key']          = $berita_detail->judul_berita;
    //return view('bappeda.berita_detail', $this->data);
    return view('web.beritadetail', $this->data);
}

public function berita($slug) {

$berita_detail = Models\Berita::where('slug_berita',$slug)->first();

$this->data['title'] = $berita_detail->judul_berita;

$this->data['beritalist'] = $berita_detail;

$this->data['desc'] = substr($berita_detail->isi,0,200).'...';

$this->data['key'] = $berita_detail->judul_berita;

//return view('bappeda.berita_detail', $this->data);

return view('web.beritadetail', $this->data);

}

When I clicked one of the ‘Profil Sekolah’ links like http://localhost:8000/page/profil-sekolah, I got this error:
“InvalidArgumentException in FileViewFinder.php line 140:
View [bappeda.halaman] not found.”
SOLUTION: SAME WITH ABOVE, Modify ‘halaman’ function in FrontController.php and replace ‘bappeda’ with ‘web’:

public function halaman($slug) {
    $detail_halaman         = Models\Data::where('slug_data',$slug)->first();
    $this->data['page']     = $detail_halaman;
    $this->data['title']    = $detail_halaman->title;
    $this->data['desc']     = strip_tags(substr($detail_halaman->content,0,200));
    return view('web.halaman', $this->data);
}

public function halaman($slug) {

$detail_halaman = Models\Data::where('slug_data',$slug)->first();

$this->data['page'] = $detail_halaman;

$this->data['title'] = $detail_halaman->title;

$this->data['desc'] = strip_tags(substr($detail_halaman->content,0,200));

return view('web.halaman', $this->data);

}

Some links still shows error like for ‘pengumuman’ (http://localhost:8000/baca/pengumuman/pembagian-raport-semester-ganjil-tahun-ajaran-2010-2011) –> check the route and make sure the model is exist
SOLUTION: There is no ‘pengumuman’ route, so add them (also for pengumuman index and detail) in /app/Http/routes.php like this:

Route::get('/pengumuman', 'FrontController@pengumumanlist');
Route::get('/baca/pengumuman/{slug}', 'FrontController@pengumuman');

1 2	Route::get('/pengumuman', 'FrontController@pengumumanlist'); Route::get('/baca/pengumuman/{slug}', 'FrontController@pengumuman');

Then in FrontController.php, like above replace ‘bappeda’ with ‘web’ for ‘pengumumanlist’ and ‘pengumuman’ functions:

public function pengumumanlist() {
    ...
    //return view('bappeda.informasi', $this->data);
    return view('web.pengumuman', $this->data);
}

public function pengumuman($slug) {
    ...
    //return view('bappeda.detail_informasi', $this->data);
    return view('web.pengumuman_detail', $this->data);
}

public function pengumumanlist() {

...

//return view('bappeda.informasi', $this->data);

return view('web.pengumuman', $this->data);

}

public function pengumuman($slug) {

...

//return view('bappeda.detail_informasi', $this->data);

return view('web.pengumuman_detail', $this->data);

}

For Galleri menu, do this:

public function album() {
    ...
    return view('web.galeri', $this->data);
}

public function foto($id) {
    ...
    return view('web.galeri_detail', $this->data);
}

public function album() {

...

return view('web.galeri', $this->data);

}

public function foto($id) {

...

return view('web.galeri_detail', $this->data);

}

Some pages in the admin (http://localhost:8000/admin) still can’t be showed up properly (some weirds characters appeared!)

It should be ready to test the website.

Dont forget to set the file permission in /public/ directory if we want to upload an image into it

teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-blog-tutorial$ sudo chmod -R 777 public/

1

teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-blog-tutorial$ sudo chmod -R 777 public/

Test the website: http://localhost:8000/

teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-blog-tutorial$ php artisan serve
Laravel development server started on http://localhost:8000/

1 2	teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-blog-tutorial$ php artisan serve Laravel development server started on http://localhost:8000/

If i found an error like:

RuntimeException in EncryptionServiceProvider.php line 31:
No supported encrypter found. The cipher and / or key length are invalid.

1 2	RuntimeException in EncryptionServiceProvider.php line 31: No supported encrypter found. The cipher and / or key length are invalid.

Just stop the server then generate the new key:

teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-blog-tutorial$ php artisan key:generate

1	teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-blog-tutorial$ php artisan key:generate

It’d create a new key in .env like

APP_KEY=SRicGuQPSaDDLOlnYCNvz7F2zdYIhXHQ

1	APP_KEY=SRicGuQPSaDDLOlnYCNvz7F2zdYIhXHQ

ref: http://laravel.io/forum/08-25-2016-no-supported-encrypter-found-the-cipher-and-or-key-length-are-invalid-when-i-run-keygenerate.
Then start the server back. If everything is okay, here is the screen look like:

Sometimes you got an error about the file permission writeable or not like this

NotWritableException in Image.php line 143:
Can't write image data to path (/home/teddy/Documents/works/laravel/laravel-blog-tutorial/public/images/1482895274.jpg)

1 2	NotWritableException in Image.php line 143: Can't write image data to path (/home/teddy/Documents/works/laravel/laravel-blog-tutorial/public/images/1482895274.jpg)

Then you need to set the file permission in /public/ directory to 777

teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-blog-tutorial$ sudo chmod -R 777 public/

1	teddy@teddy-K43SJ:~/Documents/works/laravel/laravel-blog-tutorial$ sudo chmod -R 777 public/

NOTES about this app:
The route file DONT lay in /routes/web.app BUT in /app/Http/routes.php. It used Route::group.

Route::group(['middleware' => ['web']], function () {
	// Authentication Routes
	Route::get('auth/login', ['as' => 'login', 'uses' => 'Auth\AuthController@getLogin']);
	Route::post('auth/login', 'Auth\AuthController@postLogin');
	Route::get('auth/logout', ['as' => 'logout', 'uses' => 'Auth\AuthController@getLogout']);

	// Registration Routes
	Route::get('auth/register', 'Auth\AuthController@getRegister');
	Route::post('auth/register', 'Auth\AuthController@postRegister');

	// Password Reset Routes
	Route::get('password/reset/{token?}', 'Auth\PasswordController@showResetForm');
	Route::post('password/email', 'Auth\PasswordController@sendResetLinkEmail');
	Route::post('password/reset', 'Auth\PasswordController@reset');

	// Categories
	Route::resource('categories', 'CategoryController', ['except' => ['create']]);
	Route::resource('tags', 'TagController', ['except' => ['create']]);
	
	// Comments
	Route::post('comments/{post_id}', ['uses' => 'CommentsController@store', 'as' => 'comments.store']);
	Route::get('comments/{id}/edit', ['uses' => 'CommentsController@edit', 'as' => 'comments.edit']);
	Route::put('comments/{id}', ['uses' => 'CommentsController@update', 'as' => 'comments.update']);
	Route::delete('comments/{id}', ['uses' => 'CommentsController@destroy', 'as' => 'comments.destroy']);
	Route::get('comments/{id}/delete', ['uses' => 'CommentsController@delete', 'as' => 'comments.delete']);


	Route::get('blog/{slug}', ['as' => 'blog.single', 'uses' => 'BlogController@getSingle'])->where('slug', '[\w\d\-\_]+');
	Route::get('blog', ['uses' => 'BlogController@getIndex', 'as' => 'blog.index']);
    Route::get('contact', 'PagesController@getContact');
    Route::post('contact', 'PagesController@postContact');
	Route::get('about', 'PagesController@getAbout');
	Route::get('/', 'PagesController@getIndex');
	Route::resource('posts', 'PostController');
});

Route::group(['middleware' => 'web'], function () {
    Route::auth();

    Route::get('/home', 'HomeController@index');
});

Route::group(['middleware' => ['web']], function () {

// Authentication Routes

Route::get('auth/login', ['as' => 'login', 'uses' => 'Auth\AuthController@getLogin']);

// Registration Routes

Route::get('auth/register', 'Auth\AuthController@getRegister');

Route::post('auth/register', 'Auth\AuthController@postRegister');

// Password Reset Routes

Route::get('password/reset/{token?}', 'Auth\PasswordController@showResetForm');

Route::post('password/reset', 'Auth\PasswordController@reset');

// Categories

Route::resource('categories', 'CategoryController', ['except' => ['create']]);

Route::resource('tags', 'TagController', ['except' => ['create']]);

// Comments

Route::post('comments/{post_id}', ['uses' => 'CommentsController@store', 'as' => 'comments.store']);

Route::get('comments/{id}/edit', ['uses' => 'CommentsController@edit', 'as' => 'comments.edit']);

Route::put('comments/{id}', ['uses' => 'CommentsController@update', 'as' => 'comments.update']);

Route::delete('comments/{id}', ['uses' => 'CommentsController@destroy', 'as' => 'comments.destroy']);

Route::get('comments/{id}/delete', ['uses' => 'CommentsController@delete', 'as' => 'comments.delete']);

Route::get('blog', ['uses' => 'BlogController@getIndex', 'as' => 'blog.index']);

Route::get('contact', 'PagesController@getContact');

Route::post('contact', 'PagesController@postContact');

Route::get('about', 'PagesController@getAbout');

Route::get('/', 'PagesController@getIndex');

Route::resource('posts', 'PostController');

});

Route::group(['middleware' => 'web'], function () {

Route::auth();

Route::get('/home', 'HomeController@index');

});

The route for the root website (/) is pointing to ‘PagesController.php’ in /app/Http/Controllers/

public function getIndex() {
    $posts = Post::orderBy('created_at', 'desc')->limit(4)->get();
    return view('pages.welcome')->withPosts($posts);
}

public function getIndex() {

$posts = Post::orderBy('created_at', 'desc')->limit(4)->get();

return view('pages.welcome')->withPosts($posts);

}

The ‘Post’ data is retrieved with a help from ‘Post’ model in /app/Post.php. The data then would be rendered by welcome.blade.php in /resources/views/pages/

Elance API on WordPress Without WP Plugin

Elance has gone now and merged with Odesk to establish a new company Upwork. Once I successfully used Elance API on my wordpress website without using wordpress plugin. I know it’s a bad practice but it’s work anyway. Here is how to do it:

Make sure you already registered on elance (https://elance.com) and have any elance key. If not go to https://developers.elance.com and get the keys (API Key, API secret, redirect URL, etc). Here is the keys:
SORRY, ONLY ADMIN CAN SHOW THIS!

I created a new wordpress template page with name ‘My Elance Jobs’ in a new file ‘my_elance_page.php’ in the active wordpress theme (currently the active theme is Sorbet). Based on some PHP example to use Elance API, Here is the complete content:

<?php
/*
Template Name: My Elance Jobs
*/
/*
 * The purpose of this page is to integrate my wordpress website with my elance credential through API provided by elance
 * so i can display the elance search result on my wp site. I can also filter the search result based on the keywords I like 
 * elance return json data if the API call is success then loop the json to display the result
 */
session_start();
require_once('elance-auth-lib.php');
error_reporting(E_ALL);
$api_key="my_api_key";
$consumer_secret_code="my_secret_code";
$keywords="php mysql";
$body="Nothing";

if (!isset($_GET["code"]) && empty($_SESSION['access_token'])) {
	$elance_auth = new ElanceAuthentication();
	$url = $elance_auth->RequestAccessCode($api_key, "http://www.advchaweb.com/elance");

	header("Location:".$url);
}else{				 
	//use elance library
	$elance_auth = new ElanceAuthentication();
	if(empty($_SESSION['access_token'])){
		//get the access token by feed api key and secret code
		$code = $_GET["code"];
		$json = $elance_auth->GetAccessToken($api_key, $consumer_secret_code, $code);
		 
		//Output code
		$access_token=$json->data->access_token;
		$_SESSION['access_token']=$access_token;
	}else{

	}
	// What page of data are we displaying? Defaults to 1.
	$current_page = 1;
	if (isset($_GET["currentPage"])) {

Just read the code. Try to comprehend it by yourself :). I also need to add a new file ‘elance-auth-lib.php’ for the elance API PHP wrapper in the same directory. The class ‘ElanceAuthentication’ in the file would authenticate the access to the API.

On the wordpress admin, create a new page (not post) with title ‘Elance’ then use template ‘My Elance Jobs’ then Save! It would create a new url: http://www.advchaweb.com/elance/. The url is must be same with our redirect url above!
OK. Now we can use the API from our wordpress page.Just click the link ‘Elance’ or http://www.advchaweb.com/elance
First, It’d redirect us to elance page and please log in!SORRY, ONLY ADMIN CAN SHOW THIS!
After successful login, I supposed to get the authorization page but because it is already closed, I got this page instead 🙁SOMEHOW when I click the ‘Continue to Elance’ button, I still get the authorization page!!!
SORRY, ONLY ADMIN CAN SHOW THIS!OK. Click ‘Allow’ button
It would be redirected back to my wordpress page. Because there is no job anymore on elance, I got no data!SORRY, ONLY ADMIN CAN SHOW THIS!

WordPress Plugin to Connect to Upwork API

Ref: APIS, WORDPRESS TIPS AND TRICKS, USING OAUTH IN WORDPRESS PLUGINS, PART 1: THE BASICS
How to write a WordPress plugin

Make sure you already registered on Upwork (https://upwork.com) and have any Upwork key. If not go to https://developers.upwork.com and get the keys (API Key, API secret, redirect URL, etc). Apply for the API on https://www.upwork.com/services/api/apply
Go into the plugin directory (/wp-content/plugins/) then create a new directory ‘upwork’. then in the new directory, create a new file ‘upwork.php’

Here is our first content in upwork.php file

if ( ! defined( 'ABSPATH' ) ) exit;

if(!class_exists('WP_Upwork'))

{

class WP_Upwork{

/**

public function __construct()

{

// register actions

} // END public function __construct

$wp_upwork = new WP_Upwork();

}

Add the setting page
To add the setting page, we need to add actions and callback in constructor of WP_Upwork class.

if(!class_exists('WP_Upwork'))
{
    class WP_Upwork{
        /**
         * Construct the plugin object
         */
        public function __construct()
        {
            // register actions
            // Register plugin settings
            add_action('admin_init', array(&$this, 'admin_init'));
            // Add settings page to menu
            add_action('admin_menu', array(&$this, 'add_menu'));
        } // END public function __construct
    
        ...
    } // END class WP_Upwork
} // END if(!class_exists('WP_Upwork'))

if(!class_exists('WP_Upwork'))

{

class WP_Upwork{

/**

* Construct the plugin object

public function __construct()

{

// register actions

// Register plugin settings

add_action('admin_init', array(&$this, 'admin_init'));

// Add settings page to menu

add_action('admin_menu', array(&$this, 'add_menu'));

} // END public function __construct

...

} // END class WP_Upwork

} // END if(!class_exists('WP_Upwork'))

First we set and register the Upwork setting (API Key and Secret) in WP_Upwork class:

/**
 * hook into WP's admin_init action hook
 */
public function admin_init(){
    // register your plugin's settings
    register_setting( 'wp_upwork-group', 'wp_upwork_api_key' );
    register_setting( 'wp_upwork-group', 'wp_upwork_api_secret' );
    // add your settings section
    add_settings_section(
        'wp_upwork-section', 
        'Upwork API Settings', 
        array( &$this, 'settings_section_wp_upwork'), 
        'wp_upwork_settings'
    );
    // add your setting's fields
    add_settings_field(
        'wp_upwork-api_key', 
        'API Key', 
        array(&$this, 'settings_field_input_text'), 
        'wp_upwork_settings', 
        'wp_upwork-section',
        array(
            'field' => 'wp_upwork_api_key'
        )
    );
    // add your setting's fields
    add_settings_field(
        'wp_upwork-wp_upwork_api_secret', 
        'API Secret', 
        array(&$this, 'settings_field_input_text'), 
        'wp_upwork_settings', 
        'wp_upwork-section',
        array(
            'field' => 'wp_upwork_api_secret'
        )
    );
}

public function settings_section_wp_upwork()
{
    // Think of this as help text for the section.
    echo 'Upwork API Setting:';
}
/**
 * This function provides text inputs for settings fields
 */
public function settings_field_input_text($args)
{
    // Get the field name from the $args array
    $field = esc_attr($args['field']);
    // Get the value of this setting
    $value = get_option($field);
    // echo a proper input type="text"
    echo sprintf('<input type="text" name="%s" id="%s" value="%s" />', $field, $field, $value);
} // END public function settings_field_input_text($args)

/**

* hook into WP's admin_init action hook

public function admin_init(){

// register your plugin's settings

register_setting( 'wp_upwork-group', 'wp_upwork_api_key' );

register_setting( 'wp_upwork-group', 'wp_upwork_api_secret' );

// add your settings section

add_settings_section(

'wp_upwork-section',

'Upwork API Settings',

array( &$this, 'settings_section_wp_upwork'),

'wp_upwork_settings'

);

// add your setting's fields

add_settings_field(

'wp_upwork-api_key',

'API Key',

array(&$this, 'settings_field_input_text'),

'wp_upwork_settings',

'wp_upwork-section',

array(

'field' => 'wp_upwork_api_key'

)

);

// add your setting's fields

add_settings_field(

'wp_upwork-wp_upwork_api_secret',

'API Secret',

array(&$this, 'settings_field_input_text'),

'wp_upwork_settings',

'wp_upwork-section',

array(

'field' => 'wp_upwork_api_secret'

)

);

}

public function settings_section_wp_upwork()

{

// Think of this as help text for the section.

echo 'Upwork API Setting:';

}

/**

* This function provides text inputs for settings fields

public function settings_field_input_text($args)

{

// Get the field name from the $args array

$field = esc_attr($args['field']);

// Get the value of this setting

$value = get_option($field);

// echo a proper input type="text"

echo sprintf('<input type="text" name="%s" id="%s" value="%s" />', $field, $field, $value);

} // END public function settings_field_input_text($args)

Then we add the menu ‘WP Upwork Setting’ in the Settings menu. Let’s add some code in WP_Upwork class:

/**
 * add a menu
 */     
public function add_menu()
{
    // Add a page to manage this plugin's settings
    add_options_page(
        'WP Upwork Settings', 
        'WP Upwork Settings', 
        'manage_options', 
        'wp_upwork', 
        array(&$this, 'plugin_settings_page')
    );
} // END public function add_menu()

/**
 * Menu Callback
 */     
public function plugin_settings_page()
{
    if(!current_user_can('manage_options'))
    {
        wp_die(__('You do not have sufficient permissions to access this page.'));
    }

    // Render the settings template
    //include(sprintf("%s/templates/settings.php", dirname(__FILE__)));
    ?>
    <div class="wrap">
        <h2>Upwork API Settings</h2>
        <p>You'll need to go to the <a href="https://developers.upwork.com">Upwork Developer Page</a> to setup your project and setup the values below.</p>
        <form action="options.php" method="POST">
            <?php settings_fields( 'wp_upwork-group' ); ?>
            <?php do_settings_sections( 'wp_upwork_settings' ); ?>
            <?php submit_button(); ?>
        </form>
    </div>
    <?php
} // END public function plugin_settings_page()

/**

* add a menu

public function add_menu()

{

// Add a page to manage this plugin's settings

add_options_page(

'WP Upwork Settings',

'manage_options',

'wp_upwork',

array(&$this, 'plugin_settings_page')

);

} // END public function add_menu()

/**

* Menu Callback

public function plugin_settings_page()

{

if(!current_user_can('manage_options'))

{

wp_die(__('You do not have sufficient permissions to access this page.'));

}

// Render the settings template

//include(sprintf("%s/templates/settings.php", dirname(__FILE__)));

<h2>Upwork API Settings</h2>

<p>You'll need to go to the <a href="https://developers.upwork.com">Upwork Developer Page</a> to setup your project and setup the values below.</p>

<?php settings_fields( 'wp_upwork-group' ); ?>

<?php do_settings_sections( 'wp_upwork_settings' ); ?>

<?php submit_button(); ?>

</form>

</div>

<?php

} // END public function plugin_settings_page()

Okay. Here is the menu

And here is the ‘Upwork API Settings’ page (http://localhost/works/wordpress_local/wp-admin/options-general.php?page=wp_upwork)

Save the settings
Fill the API Key and API Secret data above given by upwork then click ‘Save Changes’The above values would be saved in the database at ‘wp_options’ table. You can see them in the table like this:Here is my Upwork API Settings:SORRY, ONLY ADMIN CAN SHOW THIS!

Add Setting link next to activate/deactivate link in the plugin management list.
In the WP_Upwork class constructor, add filter ‘plugin_action_links’ like this line:

public function __construct()
{
    ...
    // Add settings link to plugins page
    add_filter( 'plugin_action_links_' . plugin_basename(__FILE__) , array( &$this , 'add_settings_link' ) );
} // END public function __construct

public function __construct()

{

...

// Add settings link to plugins page

add_filter( 'plugin_action_links_' . plugin_basename(__FILE__) , array( &$this , 'add_settings_link' ) );

} // END public function __construct

Then define the function ‘add_settings_link’ in the WP_Upwork class:

// Add the settings link to the plugins page
function add_settings_link($links)
{ 
    $settings_link = '<a href="options-general.php?page=wp_upwork">Settings</a>'; 
    array_unshift($links, $settings_link); 
    return $links; 
}

// Add the settings link to the plugins page

function add_settings_link($links)

{

$settings_link = '<a href="options-general.php?page=wp_upwork">Settings</a>';

array_unshift($links, $settings_link);

return $links;

}

Here is the result looks like:

Refactor our plugin structure a bit. Create a new directory ‘includes’ and add a new file in it ‘settings.php’. I want to move the settings in to the file to make the plugin structure better (Please learn WordPress plugin boilerplate and read How to Build a WordPress Plugin (part 1)).
Here is the content of /includes/settings.php:

Somehow I can’t put the filter ‘plugin_action_links_’ . plugin_basename(__FILE__)’ in ‘WP_Upwork_Settings’ class! The setting link can’t be displayed in the plugin main list!

Now I want to connect to Upwork API with My API key and API Secret provided by Upwork. When the connection is success, I would get the access token! I need to store the token to get more access from Upwork like searching the jobs and many more.
NOTE: I MADE A WRONG THING HERE! WHAT I THOUGHT AS ACCESS TOKEN ACTUALLY IS A REQUEST TOKEN! AND FINALLY IT’S NOT WORKING FROM HERE #9 UNTIL #13
Modify /includes/settings.php to show the token below the API Key and Secret (The token must be from Upwork so I dont have to type it manually). The screnario is every ‘Save’ button is pressed, beside the keys, the token would be updated as well. So in ‘WP_Upwork_Settings’ class constructor, add this:

class WP_Upwork_Settings{
    /**
     * Construct the plugin object
     */
    protected $action       = 'wp_upwork';
    protected $option_name  = 'wp_upwork';

    public function __construct()
    {
        ...
        // Get access token after saving data
        add_action('init', array(&$this, 'get_access_token'));
    } // END public function __construct

class WP_Upwork_Settings{

/**

* Construct the plugin object

protected $action = 'wp_upwork';

protected $option_name = 'wp_upwork';

public function __construct()

{

...

// Get access token after saving data

add_action('init', array(&$this, 'get_access_token'));

} // END public function __construct

Then show the label for the access token in ‘admin_init’ and ‘settings_field_label’ function:

public function admin_init(){
    // register your plugin's settings
    ...
    register_setting( 'wp_upwork-group', 'wp_upwork_access_token' );
    ...
    // add your setting's fields
    add_settings_field(
        'wp_upwork-wp_upwork_access_token', 
        __('Access Token'), 
        array(&$this, 'settings_field_label'), 
        'wp_upwork_settings', 
        'wp_upwork-section',
        array(
            'field' => 'wp_upwork_access_token'
        )
    );
}
...
/**
 * This function provides label for settings fields
 */
public function settings_field_label($args)
{
    // Get the field name from the $args array
    $field = esc_attr($args['field']);
    // Get the value of this setting
    $value = get_option($field);
    // echo a proper input type="text"
    echo sprintf('<label name="%s" id="%s">%s</label>', $field, $field, $value);
} // END public function settings_field_input_text($args)

public function admin_init(){

// register your plugin's settings

...

register_setting( 'wp_upwork-group', 'wp_upwork_access_token' );

...

// add your setting's fields

add_settings_field(

'wp_upwork-wp_upwork_access_token',

__('Access Token'),

array(&$this, 'settings_field_label'),

'wp_upwork_settings',

'wp_upwork-section',

array(

'field' => 'wp_upwork_access_token'

)

);

}

...

/**

* This function provides label for settings fields

public function settings_field_label($args)

{

// Get the field name from the $args array

$field = esc_attr($args['field']);

// Get the value of this setting

$value = get_option($field);

// echo a proper input type="text"

echo sprintf('<label name="%s" id="%s">%s</label>', $field, $field, $value);

} // END public function settings_field_input_text($args)

Modify ‘plugin_settings_page’ function to add a new hidden value ‘wp_nonce_field’ and change the button title to ‘Save and Get Access Token’.

public function plugin_settings_page()
{
    ...
    ?>
    <div class="wrap">
        <h2><?php _e('Upwork API Settings','wp_upwork'); ?></h2>
        <p><?php _e('You\'ll need to go to the <a href="https://developers.upwork.com">Upwork Developer Page</a> to setup your project and setup the values below.'); ?></p>
        <form action="options-general.php?page=wp_upwork" method="POST">
            <?php settings_fields( 'wp_upwork-group' ); ?>
            <?php wp_nonce_field( $this->action, $this->option_name . '_nonce', FALSE ); ?>
            <?php do_settings_sections( 'wp_upwork_settings' ); ?>
            <?php submit_button(__('Save and Get Access Token')); ?>
        </form>
    </div>
    <?php
} // END public function plugin_settings_page()

public function plugin_settings_page()

{

...

<p><?php _e('You\'ll need to go to the <a href="https://developers.upwork.com">Upwork Developer Page</a> to setup your project and setup the values below.'); ?></p>

<?php settings_fields( 'wp_upwork-group' ); ?>

<?php wp_nonce_field( $this->action, $this->option_name . '_nonce', FALSE ); ?>

<?php do_settings_sections( 'wp_upwork_settings' ); ?>

<?php submit_button(__('Save and Get Access Token')); ?>

</form>

</div>

<?php

} // END public function plugin_settings_page()

The hidden value would be submitted and be caught to inspect the keys and get the access token in ‘get_access_token’ function.

/**

There is an important setting to pass the configuration beside ‘consumer key’ and ‘consumer secret’, it’s ‘authType’. I tried ‘OAuth1’ but it didn’t work. the work is ‘OAuthPHPLib’.

Use composer to download the Upwork API for PHP (https://github.com/upwork/php-upwork). Create a new composer.json file in our main plugin directory. Here is the content:

{
    "name": "advcha/upwork",
    "require": {
        "upwork/php-upwork": "dev-master"
    }
}

{

"name": "advcha/upwork",

"require": {

"upwork/php-upwork": "dev-master"

}

Now use terminal and download the API PHP library

Generating autoload files

This would create a new directory ‘vendor’ in the main our plugin directory. The API would be there!
Read how to use autoload and composer for developing wordpress plugin: Improving WordPress Development Workflow with Composer, Managing Your WordPress Site with Git and Composer Part 2 – Using Composer to Manage Themes and Plugins and How To Use Autoloading And A Plugin Container In WordPress Plugins.

We need to add the autoload in upwork.php file so we can use the API library:

require __DIR__ . '/vendor/autoload.php';

1	require __DIR__ . '/vendor/autoload.php';

With this only single line, we dont need to include/require the API library manually like this (/includes/settings.php at ‘admin_post’ function):

/*require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/Config.php');
require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/Client.php');
require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/Debug.php');
require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/Interfaces/Client.php');
require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/AuthTypes/AbstractOAuth.php');
require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/AuthTypes/OAuth1.php');*/

/*require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/Config.php');

require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/Client.php');

require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/Debug.php');

require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/Interfaces/Client.php');

require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/AuthTypes/AbstractOAuth.php');

require_once(WP_UPWORK_PLUGIN_DIR . '/src/Upwork/API/AuthTypes/OAuth1.php');*/

Here is how it looksWhen the button is pressed, if nothing wrong the access token and the access token secret would be revealed like this:SORRY, ONLY ADMIN CAN SHOW THIS!

Now I want to store the tokens values in database so later we can get the values and use its for Upwork API functions.
Modify ‘get_access_token’ function in /includes/settings.php file to get the tokens and save its. I use ‘update_option’ function to do its (https://codex.wordpress.org/Function_Reference/update_option)

public function get_access_token()
{
    if(isset($_POST[ $this->option_name . '_nonce' ])){
        if ( wp_verify_nonce( $_POST[ $this->option_name . '_nonce' ], $this->action ) ){
            if ( isset ( $_POST[ 'wp_upwork_api_key' ] ) && isset ( $_POST[ 'wp_upwork_api_secret' ] )){
                ...
                $client=new \Upwork\API\Client($config);
                $requestTokenInfo = $client->getRequestToken();
                if(isset($requestTokenInfo['oauth_token']) && isset($requestTokenInfo['oauth_token_secret'])){
                    //save/update the tokens in database
                    update_option('wp_upwork_access_token', $requestTokenInfo['oauth_token']);
                    update_option('wp_upwork_access_token_secret', $requestTokenInfo['oauth_token_secret']);
                }else{
                    var_dump($client->getRequestToken());
                    exit;
                }
                
            }
            //exit;
        }
    }
} // END public function get_access_token()

public function get_access_token()

{

if(isset($_POST[ $this->option_name . '_nonce' ])){

if ( wp_verify_nonce( $_POST[ $this->option_name . '_nonce' ], $this->action ) ){

if ( isset ( $_POST[ 'wp_upwork_api_key' ] ) && isset ( $_POST[ 'wp_upwork_api_secret' ] )){

...

$client=new \Upwork\API\Client($config);

$requestTokenInfo = $client->getRequestToken();

if(isset($requestTokenInfo['oauth_token']) && isset($requestTokenInfo['oauth_token_secret'])){

//save/update the tokens in database

update_option('wp_upwork_access_token', $requestTokenInfo['oauth_token']);

update_option('wp_upwork_access_token_secret', $requestTokenInfo['oauth_token_secret']);

}else{

var_dump($client->getRequestToken());

exit;

}

//exit;

}

} // END public function get_access_token()

If everything right, here is how it would looks like

<OLD>
You can also check the tokens values. Not only the value for access token (‘wp_upwork_access_token’) but also for access token secret’s value (‘wp_upwork_access_token_secret’). No reason to display the secret’s value here.
</OLD>
<NEW>
Actually I GOT THE REQUEST TOKEN ABOVE NOT THE ACCESS TOKEN!! SO UPWORK GAVE REQUEST TOKEN FIRST THEN GIVE BACK THE ACCESS TOKEN IF SUCCESS!
READ THIS FOR THE WORKFLOW: https://developers.upwork.com/?lang=php#authentication_oauth-10

I tried to get the access token (actually I just realized I got the request token not the access token)

https://www.upwork.com/services/api/www.advchaweb.com/upwork?oauth_token=708638d60eee72f4c7c133a2617b15ef&oauth_verifier=b57428447a10ef831db125a1c9f6e648
IT SHOULD BE LIKE:
http://localhost/works/wordpress_local/wp-admin/options-general.php?page=wp_upwork&oauth_token=63c1ab57d81ef2a120dc122255f252fd&oauth_verifier=4601823dab3c049d2d71be0f76a48a7cUNTIL HERE, IT’S NOT WORKING AS EXPECTED. I NEED TO TRY THIS SAMPLE https://github.com/upwork/php-upwork/blob/master/example/web.php
I MAKE THE SAMPLE LOCALLY: http://localhost/works/upwork_api/ AND IT’S WORKING FOR THE FIRST TIME (NOT WORKING AFTER THAT. MEANS NO DATA CAN I GET FROM UPWORK!!!)
SORRY, ONLY ADMIN CAN SHOW THIS!
After a few hours I tried again to call the Upwork API via http://localhost/works/upwork_api AND it’s working again. Actually to get the access token and call a function (like User), it takes four web call.
SORRY, ONLY ADMIN CAN SHOW THIS!

Because I failed to get the access token from ‘get_access_token’ function, I tried to use Custom Page Template (Please read Add Page Templates to WordPress with a Plugin) like I used to use it for Elance API. But it different here. I dont have to inject the php file in the active theme. I can use it from my plugin!
Okay. I need to clean my code and remove the previous changes above (from #9 and #14) about the tokens field and the ‘get_access_token’ function.
SORRY, ONLY ADMIN CAN SHOW THIS!
SO I BACK TO THE PREVIOUS CODE WHERE THE WP_Upwork plugin in the admin page only to store API Key and API Secret!
Back to our custom page template, create a new file ‘template.php’ in /includes/ directory. this file would consist of a class ‘WP_Upwork_Template’. This class would get the template file, show it on the page/post page dropdown template and render/view it.

The template name is in a file ‘upwork-template.php’ in the same directory (/includes/). this file is the main page to connect to Upwork API (authenticate, authorize/get access token and call the Upwork API functions). This content looks like same with https://github.com/upwork/php-upwork/blob/master/example/web.php. Only API key and API secret I got from database. For a test only and to prove it can work as expected, here is the file content:

The template name is ‘Upwork Template’

Then create a new page ‘Upwork’ and select the template ‘Upwork Template’

Okay. One more thing. It’s better to change the permalink of our page url to http://localhost/works/wordpress_local/upwork/ instead of http://localhost/works/wordpress_local/?p=123. To do this, please go to Settings -> Permalinks -> Select ‘Post name’ Then Click ‘Save Changes’. It’d change the page url like above. BUT if you open the link and show 404 error, it means something wrong on your .htaccess or the permission or the apache2 setting. I tried many thing from

teddy@teddy-K43SJ:~/Documents/works/wordpress_local$ sudo chmod 777 .htaccess 
teddy@teddy-K43SJ:~/Documents/works/wordpress_local$ sudo service apache2 restart

1 2	teddy@teddy-K43SJ:~/Documents/works/wordpress_local$ sudo chmod 777 .htaccess teddy@teddy-K43SJ:~/Documents/works/wordpress_local$ sudo service apache2 restart

teddy@teddy-K43SJ:~/Documents/works/wordpress_local$ sudo a2enmod rewrite
Module rewrite already enabled

1 2	teddy@teddy-K43SJ:~/Documents/works/wordpress_local$ sudo a2enmod rewrite Module rewrite already enabled

BUT NOTHING IS WORKING. IT’S FINALLY WORKING IS FROM http://askubuntu.com/questions/48362/how-to-enable-mod-rewrite-in-apache. I need to put ‘AllowOverride All’ in the default apache2 configuration file:

teddy@teddy-K43SJ:~/Documents/works/wordpress_local$ sudo gedit /etc/apache2/sites-available/000-default.conf

1	teddy@teddy-K43SJ:~/Documents/works/wordpress_local$ sudo gedit /etc/apache2/sites-available/000-default.conf

Then add these lines:

<VirtualHost *:80>
	...
	DocumentRoot /var/www/html
	
	<Directory "/var/www/html">
		AllowOverride All
	</Directory>

	...
</VirtualHost>

...

DocumentRoot /var/www/html

AllowOverride All

</Directory>

...

</VirtualHost>

Then restart apache2 server.
Okay. It’s working now. It can open http://localhost/works/wordpress_local/upwork correctly. ALSO DON’T FORGET TO CHANGE AND SAVE Callback URL IN UPWORK API PAGE (https://www.upwork.com/services/api/keys).
SORRY, ONLY ADMIN CAN SHOW THIS!

Modify ‘upwork-template.php’ so we can save the access token and no need to get new token each API call. I tried like this:
