OSClass Tips and Tricks

Create a plugin to remove ad/listing spam. currently the item list only can show 100 ad max. create a plugin so it can remove as many ad as we want???

How to delete more than 100 listing on the ‘manage listing’ page on the admin page?
SOLUTION: (NOT COMPLETED YET) need to learn the code in /oc-admin/items.php

but Params::getParam(‘id’) only can see the ‘id’ on the checked values on the manage list. even though the max listing on the list only 100. so how to delete more than that??? learn again this line:

OK. now how to get the list all of the item id??? or from an item id to another item id??? HOMEWORK!!!
OK. I can do this without use the admin listing page. but instead of creating a new plugin (it’d need more work), I use another plugin (use the functions, model, etc). its real esatet plugin. First of all, in /plugins/realestate_attributes/ModelRealEstate.php file, I added two functions. The first to call the item table and the second to populate the specific item data based on our criteria.

Then in /plugins/realestate_attributes/conf.php file, we call those function at the beginning.

We can run it on our browser with url http://localhost/…/oc-admin/index.php?page=plugins&action=renderplugin&file=realestate_attributes/conf.php. But becareful to use this script. If we have many records that need to be deleted, it’d take many time and computer/server resource. sometimes I got a message: “Fatal error: Maximum execution time of 30 seconds exceeded in /home/…/oc-includes/osclass/model/Item.php on line 128“. So check your server setting! Do you have more elegant solutions?

How to create multi step posting ad page?
currently multi step can’t move back to the previous step (http://localhost/works/kokopage/index.php?page=item&action=item_add). I have to refresh it. but can use ‘previous’ button?
The Steps (previous and next) on each page are showed up by helping of jquery. the jquery script is reside in /themes/classer/js/FormToWizard.js

Then call the script on /themes/classer/item-post.php like this

OSCLASS TIPS & TRICKS
1. show warning and error on page -> Put define(‘OSC_DEBUG’, true) ; in config.php
2. show sql query on page -> Put define(‘OSC_DEBUG_DB’, true) ; in config.php
3. Change item url from http://localhost/Projects/motobroker/sedans/auction-1_i60
to http://localhost/Projects/motobroker/victoria/airport-west/sedans/auction-1_i60 (incluided region and city), pls do this (hard code) :
a. edit oc_t_preference table and find ‘rewrite_item_url’. then change from {CATEGORIES}/{ITEM_TITLE}_i{ITEM_ID}
to {ITEM_REGION}/{ITEM_CITY}/{CATEGORIES}/{ITEM_TITLE}_i{ITEM_ID}
NOTE: We can’t just use {ITEM_REGION}/{ITEM_CITY}/{CATEGORIES}/{ITEM_TITLE} . it’d display 404 page. we must add ‘_i{ITEM_ID}’ at the end
b. find and edit function ‘osc_item_url_from_item’ in /oc-includes/osclass/helpers/hDefines.php. add the region part :
$url = str_replace(‘{ITEM_REGION}’, osc_sanitizeString($item[‘s_region’]), $url);
so it’ll be
function osc_item_url_from_item($item, $locale = ”)
{
if ( osc_rewrite_enabled() ) {
$url = osc_get_preference(‘rewrite_item_url’);
if( preg_match(‘|{CATEGORIES}|’, $url) ) {
$sanitized_categories = array();
$cat = Category::newInstance()->hierarchy($item[‘fk_i_category_id’]);
for ($i = (count($cat)); $i > 0; $i–) {
$sanitized_categories[] = $cat[$i – 1][‘s_slug’];
}
$url = str_replace(‘{CATEGORIES}’, implode(“/”, $sanitized_categories), $url);
}
$url = str_replace(‘{ITEM_ID}’, osc_sanitizeString($item[‘pk_i_id’]), $url);
$url = str_replace(‘{ITEM_REGION}’, osc_sanitizeString($item[‘s_region’]), $url);
$url = str_replace(‘{ITEM_CITY}’, osc_sanitizeString($item[‘s_city’]), $url);
$url = str_replace(‘{ITEM_TITLE}’, osc_sanitizeString($item[‘s_title’]), $url);
$url = str_replace(‘?’, ”, $url);
if($locale!=”) {
$path = osc_base_url().$locale.”/”.$url;
} else {
$path = osc_base_url().$url;
}
} else {
$path = osc_item_url_ns($item[‘pk_i_id’], $locale);
}
return $path;
}

4. Get static page url : If we want to get an url of the static/customized page, pls do like this (http://forums.osclass.org/general-help/get-url-of-a-page/):
<?php osc_get_static_page(‘page_name’); ?>
<a href=”<? php echo osc_static_page_url(); ?>”>Page Title</a>

5. How to find out if this the admin page or not?
Pls use:    if( OC_ADMIN ) {

5. How to send/flash message?
Pls use like this (before the redirection):
osc_add_flash_ok_message(__(‘Killer form deleted correctly’, ‘jobboard’), ‘admin’); //success/ok message
osc_add_flash_info_message(__(‘Killer form deleted correctly’, ‘jobboard’), ‘admin’); //info/notif message
osc_add_flash_message(__(‘Problems tring to remove killer question form. Try it again.’, ‘jobboard’), ‘admin’);//errro message
osc_add_flash_error_message(__(“Name is required”, ‘jobboard’));//error message
For the redirection, pls use:
osc_redirect_to(osc_admin_render_plugin_url(“jobboard/manage_killer.php”)); //sometime return error/warning
job_js_redirect_to(osc_admin_render_plugin_url(“jobboard/manage_killer.php”)); //sometime return error/warning
header(‘Location: ‘ . osc_admin_render_plugin_url(“jobboard/people.php”)); exit;//usually success

6. How to load the classes in the plugin? especially for loading MVC (model, view and controller) class (no controller here)
pls do like this (in plugin index.php): ref: /osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/index.php

define(‘JOBBOARD_PATH’, dirname(__FILE__) . ‘/’);
define(‘JOBBOARD_VIEWS’, JOBBOARD_PATH . ‘views/’);

require_once(JOBBOARD_PATH . ‘model/ModelJB.php’);
require_once(JOBBOARD_PATH . ‘model/ModelKQ.php’);
…

7. Put all actions (hooks) in a class
usually hooks reside in index.php of plugins. but here we can put them in a class and call it like this:
/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/index.php:
define(‘JOBBOARD_PATH’, dirname(__FILE__) . ‘/’);
define(‘JOBBOARD_VIEWS’, JOBBOARD_PATH . ‘views/’);

…
require_once(JOBBOARD_PATH . ‘class/JobboardListingActions.php’);
…

// init classes
…
$jb_listing_actions = new JobboardListingActions();
…

/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/class/JobboardListingActions.php:
class JobboardListingActions
{
public function __construct() {
// add/add-post
osc_add_hook(‘item_form’,          array(&$this, ‘jobboard_form’) );
osc_add_hook(‘posted_item’,        array(&$this, ‘jobboard_form_post’) );
…
}

function jobboard_form($catID = null) {
…
}
}
Here we must use a reference (&) to return the callback values like this: array(&$this, ‘jobboard_form’) )

8. how to create/display a toolbar menu in admin dashboard?
we can put them in a class and call it like this:
/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/index.php:
define(‘JOBBOARD_PATH’, dirname(__FILE__) . ‘/’);
define(‘JOBBOARD_VIEWS’, JOBBOARD_PATH . ‘views/’);

…
if( OC_ADMIN ) {
…
require_once(JOBBOARD_PATH . ‘class/JobboardAdminMenu.php’);
…

// init oc-admin classes
…
$jb_admin_menu      = new JobboardAdminMenu();
…
}
…

/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/class/JobboardAdminMenu.php:
class JobboardAdminMenu
{
public function __construct() {
osc_add_hook(‘admin_menu_init’, array(&$this, ‘init’));
}

/**
* Add new menu entries
*/
public function init() {
osc_add_admin_menu_page(
__(‘Jobboard’, ‘jobboard’),
osc_admin_render_plugin_url(“jobboard/dashboard.php”),
‘jobboard’,
‘moderator’
);

osc_add_admin_submenu_page(
‘jobboard’,
__(‘Dashboard’, ‘jobboard’),
osc_admin_render_plugin_url(“jobboard/dashboard.php”),
‘jobboard_dash’,
‘moderator’
);

osc_add_admin_submenu_page(
‘jobboard’,
__(‘Applicants’, ‘jobboard’),
osc_admin_render_plugin_url(“jobboard/people.php”),
‘jobboard_people’,
‘moderator’
);

// killer questions menu
osc_add_admin_submenu_page(
‘jobboard’,
__(‘Killer Questions’, ‘jobboard’),
osc_admin_render_plugin_url(“jobboard/manage_killer.php”),
‘jobboard_killer’,
‘moderator’
);

osc_add_admin_submenu_page(
‘jobboard’,
__(‘Download resumes’, ‘jobboard’),
osc_admin_render_plugin_url(“jobboard/resume_download.php”),
‘jobboard_resumedownload’,
‘moderator’
);

osc_add_admin_submenu_page(
‘jobboard’,
__(‘Default locations’, ‘jobboard’),
osc_admin_render_plugin_url(“jobboard/admin/settings.php”),
‘jobboard_locations’,
‘moderator’
);
}

Here we use ‘osc_add_admin_menu_page’ to create the toolbar and ‘osc_add_admin_submenu_page’ to create the sub-toolbar

9. We better use ‘Cookie’ to send a value just from a page to another page instead of ‘Session’. in the another page we can use ????? With ‘cookies’ we can set and store how long (day, month or year) the values would last but ‘session’ only for current values (in a day)
ref:/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/index.php:
…
if( Params::getParam(‘iDisplayLength’) != ” ) {
Cookie::newInstance()->push(‘applicants_iDisplayLength’, Params::getParam(‘iDisplayLength’));
Cookie::newInstance()->set();
} else {
// set a default value if it’s set in the cookie
if( Cookie::newInstance()->get_value(‘applicants_iDisplayLength’) != ” ) {
Params::setParam(‘iDisplayLength’, Cookie::newInstance()->get_value(‘applicants_iDisplayLength’));
} else {
Params::setParam(‘iDisplayLength’, 10);
}
}

9. Is it better to use ‘osc_get_preference’ and ‘osc_set_preference’??
Its better to use those functions to store/get values for the plugins settings
example:
ref:/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/people.php:
$feature = (int) osc_get_preference(‘new_feature_add_applicant’, ‘jobboard_plugin’);
if( $feature === 0 ) {
osc_set_preference(‘new_feature_add_applicant’, 1, ‘jobboard_plugin’);
}

10. For what and why use View::newInstance()->_exportVariableToView(‘items’, $aItems); ??
The code will export/spit out items with some ‘items helper’ function on ‘View’ class that we can use like osc_item_id(), osc_item_category_id(), etc
We can use this code to get the ‘items’ data by primary key without the helpers:
$item = Item::newInstance()->findByPrimaryKey($applicant[‘fk_i_item_id’]);
echo $item[‘s_title’]; –> CAN’T GET $item[‘s_title’]
another variations:
ref:/plugins/mb_auction/ModelMBAuction.php:
View::newInstance()->_exportVariableToView(‘items’, Search::newInstance()->doSearch());
View::newInstance()->_exportVariableToView(“item”, Item::newInstance()->findByPrimaryKey($itemId));
ref:/plugins/mb_auction/themes/default/auction_dashboard_widget.php:
View::newInstance()->_exportVariableToView(‘footer_link’, $f);
10. How to loop search result (can use osc_item_id())
Pls do this:
ref:/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/people.php:
$mSearch = new Search();
$mSearch->limit(0, 100);
$aItems = $mSearch->doSearch();
View::newInstance()->_exportVariableToView(‘items’, $aItems);
then we can use the helpers functions like ‘osc_item_id()’
if we want to search something simple and just return the result count, we can do it like this:
ref:/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/dashboard.php:
<?php
$mSearch = new Search(true);
$mSearch->addItemConditions(DB_TABLE_PREFIX.’t_item.b_enabled = 1′);
?>
</div>
<b><?php echo $mSearch->count(); ?></b>
‘new Search(true)’ mean we can also search the ‘expired’ item (ref:/oc-includes/osclass/model/Search.php)
‘Search’ class only to search data in the ‘oc_t_item’ table.
or we can also use like this with some search queries (use ‘addItemConditions’):
ref:/kokopage/oc-content/themes/classer/functions.php: (similar query)
View::newInstance()->_exportVariableToView(‘items’, array());//I dont know if its better to empty the ‘items’ first
$mSearch = new Search();
$mSearch->addCategory(osc_item_category_id());
$mSearch->addItemConditions(sprintf(“%st_item.pk_i_id != %s “, DB_TABLE_PREFIX, osc_item_id()));
$mSearch->limit(‘0’, $max_item);

$aItems = $mSearch->doSearch();
$iTotalItems = count($aItems);
if( $iTotalItems > 0 ) {
View::newInstance()->_exportVariableToView(‘items’, $aItems);
return $iTotalItems;
}
unset($mSearch);

return 0;
then in the loop:
<?php while( osc_has_items() ) { ?>
<?php echo osc_item_id(); ?>
<?php } ?>

or we can also do like this (more complex queries):
ref:/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/dashboard.php:
$mSearch4 = new Search(true);
$mSearch4->addTable(DB_TABLE_PREFIX.”t_item_stats”);
$mSearch4->addField(“SUM(“.DB_TABLE_PREFIX.”t_item_stats.i_num_views) as i_num_views”);
$mSearch4->addConditions(DB_TABLE_PREFIX.”t_item_stats.fk_i_item_id = “.DB_TABLE_PREFIX.”t_item.pk_i_id”);
$mSearch4->order(‘i_num_views’);
$mSearch4->set_rpp(1);
$mSearch4->addGroupBy(“fk_i_item_id”);
$mostViewedJob = $mSearch4->doSearch();
Without export it to ‘View’ because it only return 1 record, we can get the data without looping like this:
$mostViewedJob[0][‘i_num_views’]
$mostViewedJob[0][‘fk_i_item_id’]
$mostViewedJob[0][‘s_title’]

or even like this (more2 complex query):
ref:/kokopage/oc-content/themes/classer/functions.php: (featured listing):
function featured_listings() {
$category_id=0;
$category_query=””;
if(Params::getParam(‘sCategory’)){
$cats=array();
$cat=Category::newInstance()->findNameByPrimaryKey(Params::getParam(‘sCategory’));
if($cat){
//find in the sub category
$subCategories = Category::newInstance()->toSubTree(Params::getParam(‘sCategory’));
if($subCategories){
foreach($subCategories as $s){
$cats[]=$s[‘pk_i_id’];
}
$category_id=Params::getParam(‘sCategory’).’,’.implode($cats,’,’);
$category_query=”IN (“.$category_id.”)”;
}else{
$category_id=Params::getParam(‘sCategory’);
$category_query=”= “.$category_id;
}
}else{
//category id is not exist
$category_id=-1;
$category_query=”= -1″;
}
}
$max_item=16;
$mSearch = new Search();
$mSearch->addTable(DB_TABLE_PREFIX.”t_item_promoted_ad”);
$mSearch->addConditions(DB_TABLE_PREFIX.”t_item.pk_i_id = “.DB_TABLE_PREFIX.”t_item_promoted_ad.fk_i_item_id”);
if($category_id)
$mSearch->addConditions(DB_TABLE_PREFIX.”t_item.fk_i_category_id “.$category_query);
$mSearch->addConditions(DB_TABLE_PREFIX.”t_item_promoted_ad.i_paid = 1″);
$mSearch->addConditions(DB_TABLE_PREFIX.”t_item_promoted_ad.dt_expiration IS NOT NULL”);
$mSearch->order(DB_TABLE_PREFIX.”t_item.pk_i_id”);
$mSearch->addGroupBy(DB_TABLE_PREFIX.”t_item.pk_i_id”);
$mSearch->limit(‘0’, $max_item);

$aItems = $mSearch->doSearch();
$iTotalItems = count($aItems);
if( $iTotalItems > 0 ) {
View::newInstance()->_exportVariableToView(‘items’, $aItems);
return $iTotalItems;
}
unset($mSearch);

return 0;
}

11. How to find ‘Total View’?
pls use ‘ItemStats’ static class like this:
ref:/osclass_plugin_test/oc-content/plugins/plugin-jobboard-master/dashboard.php:

define(‘ABS_PATH’, dirname(dirname(dirname(dirname($_SERVER[‘SCRIPT_FILENAME’])))) . ‘/’);
require_once(ABS_PATH . ‘oc-load.php’);
or if we know the file we want to include in ‘/oc-includes’ directory, just use ‘osc_lib_path()’ like this:
require_once(osc_lib_path() . ‘osclass/helpers/hErrors.php’);
13. How to make ‘download/upload’ pdf file?

21. we can render custom ‘user menu’ (the left section that hase some links like : dashboard, profile, account, paymnet, etc) on the user dashboard (like here http://localhost/Projects/kokopage/index.php?page=user&action=items). on the /classer/user-items.php we can display it like this:
<div class=”userMenus boxwhite hasmb”>
<?php echo osc_private_user_menu( get_user_menu() ); ?>
<?php //echo osc_private_user_menu(  );//<–default user menu ?>
</div>
Here is the custom ‘user menu’ function ‘get_user_menu’ defined in /classer/functions.php:
function get_user_menu() {
$options   = array();
$options[] = array(
‘name’ => __(‘<i class=”icon-certificate”></i> Public Profile’),
‘url’ => osc_user_public_profile_url(),
‘class’ => ‘opt_publicprofile’
);
$options[] = array(
‘name’  => __(‘<i class=”icon-list-numbered”></i> Listings’, ‘classer’),
‘url’   => osc_user_list_items_url(),
‘class’ => ‘opt_items’
);
$options[] = array(
‘name’ => __(‘<i class=”icon-bell-alt”></i> Alerts’, ‘classer’),
‘url’ => osc_user_alerts_url(),
‘class’ => ‘opt_alerts’
);
$options[] = array(
‘name’  => __(‘<i class=”icon-cogs”></i> Account’, ‘classer’),
‘url’   => osc_user_profile_url(),
‘class’ => ‘opt_account’
);
$options[] = array(
‘name’  => __(‘<i class=”icon-mail-2″></i> Change email’, ‘classer’),
‘url’   => osc_change_user_email_url(),
‘class’ => ‘opt_change_email’
);
$options[] = array(
‘name’  => __(‘<i class=”icon-edit-1″></i> Edit username’, ‘classer’),
‘url’   => osc_change_user_username_url(),
‘class’ => ‘opt_change_username’
);
$options[] = array(
‘name’  => __(‘<i class=”icon-key”></i> Change password’, ‘classer’),
‘url’   => osc_change_user_password_url(),
‘class’ => ‘opt_change_password’
);
$options[] = array(
‘name’  => __(‘<i class=”icon-trash”></i> Delete account’, ‘classer’),
‘url’   => ‘#’,
‘class’ => ‘opt_delete_account’
);

return $options;
}
22. How to find out how many ‘paid ads’ or ‘premium ads’?
pls use this: (/classer/inc/user-stats.php)
<?php
$searchPrem = new Search();
$searchPrem->addConditions(sprintf(“b_premium = %d”, 1));
$searchPrem->addConditions(sprintf(“fk_i_user_id = %d”, osc_logged_user_id()));
$searchPrem->limit(0, 1000);//<– dont forget to add ‘limit’. somehow it just came up with 10 data
$premiumItems = $searchPrem->doSearch();
echo count($premiumItems);
?>
somehow i can’t use <?php echo osc_priv_count_premiums(); ?>
23. How to find out how many ‘alerts’?
pls use this: (/classer/inc/user-stats.php)
<?php
$searchAlert = new Search();
$searchAlert->addTable(DB_TABLE_PREFIX.”t_alerts”);
$searchAlert->addConditions(sprintf(“b_active = %d”, 1));
$searchAlert->addConditions(sprintf(“fk_i_user_id = %d”, osc_logged_user_id()));
$searchAlert->limit(0, 1000);//<– dont forget to add ‘limit’. somehow it just came up with 10 data
$alerts = $searchAlert->doSearch();
echo count($alerts);
?>
somehow i can’t use <?php echo osc_count_alerts(); ?>

24. jQuery is not be recognized in certain page (ie. user change email or user change password).
We can include it at the top of those page by using:
osc_enqueue_script(‘jquery-validate’);
note: ‘jquery-validate’ script must exist in the current theme.
25. ‘osc_user_items_validated’ function in /classer/inc/user-stats.php didnt work also on the overlay header. the case is same with above (‘osc_user_id’ didnt give any result so use ‘osc_logged_user_id’ instead):
<?php
if(osc_user_id())
echo osc_user_items_validated();
else{
$searchItem = new Search();
$searchItem->addConditions(sprintf(“b_enabled = %d”, 1));
$searchItem->addConditions(sprintf(“fk_i_user_id = %d”, osc_logged_user_id()));
$searchItem->limit(0, 1000);//<– dont forget to add ‘limit’. somehow it just came up with 10 data
$items = $searchItem->doSearch();
echo count($items);
}
?>
26. Modifying the pagination display:
ref: /plugins/payment/admin/manage.php:
function showingResults(){
$aData = __get(“aData”);
echo ‘<ul class=”showing-results”><li><span>’.osc_pagination_showing((Params::getParam(‘iPage’)-1)*$aData[‘iDisplayLength’]+1, ((Params::getParam(‘iPage’)-1)*$aData[‘iDisplayLength’])+count($aData[‘aRows’]), $aData[‘iTotalDisplayRecords’], $aData[‘iTotalRecords’]).'</span></li></ul>’;
}
osc_add_hook(‘before_show_pagination_admin’,’showingResults’);
osc_show_pagination_admin($aData);

27. Load the items with the pagination:
ref:kokopage/oc-content/plugins/watchlist/watchlist.php
$i_userId = osc_logged_user_id();
if(Params::getParam(‘delete’) != ” && osc_is_web_user_logged_in()){
delete_item(Params::getParam(‘delete’), $i_userId);
}

$itemsPerPage = (Params::getParam(‘itemsPerPage’) != ”) ? Params::getParam(‘itemsPerPage’) : 5;
$iPage        = (Params::getParam(‘iPage’) != ”) ? Params::getParam(‘iPage’) : 0;

Search::newInstance()->addConditions(sprintf(“%st_item_watchlist.fk_i_user_id = %d”, DB_TABLE_PREFIX, $i_userId));
Search::newInstance()->addConditions(sprintf(“%st_item_watchlist.fk_i_item_id = %st_item.pk_i_id”, DB_TABLE_PREFIX, DB_TABLE_PREFIX));
Search::newInstance()->addTable(sprintf(“%st_item_watchlist”, DB_TABLE_PREFIX));
Search::newInstance()->page($iPage, $itemsPerPage);

$aItems      = Search::newInstance()->doSearch();
$iTotalItems = Search::newInstance()->count();
$iNumPages   = ceil($iTotalItems / $itemsPerPage) ;

View::newInstance()->_exportVariableToView(‘items’, $aItems);
View::newInstance()->_exportVariableToView(‘search_total_pages’, $iNumPages);
View::newInstance()->_exportVariableToView(‘search_page’, $iPage) ;

or kokopage/oc-content/plugins/payment/user/menu.php

View::newInstance()->_exportVariableToView(‘search_total_pages’, $iNumPages);
View::newInstance()->_exportVariableToView(‘search_page’, $page) ;

29. If we manually loop some items and we want to show the items properties (like title, description, images, etc), usually we can do it by using like this:
<?php foreach($payments as $pay) { ?>
…
<?php
$itemId=$pay[‘fk_i_item_id’];
if($itemId != 0){
View::newInstance()->_exportVariableToView(“item”, Item::newInstance()->findByPrimaryKey($itemId));
…
?>
<?php if(osc_count_item_resources()) { ?>
<div class=”img”>
<a class=”listing-thumb” href=”<?php echo osc_item_url() ; ?>” title=”<?php echo osc_esc_html(osc_item_title()) ; ?>”>
<img src=”<?php echo osc_resource_thumbnail_url(); ?>” title=”” alt=”<?php echo osc_esc_html(osc_item_title()) ; ?>” width=”<?php echo $size[0]; ?>” height=”<?php echo $size[1]; ?>”>
</a>
</div>
<?php } else { ?>
<div class=”img”>
<a class=”listing-thumb” href=”<?php echo osc_item_url() ; ?>” title=”<?php echo osc_esc_html(osc_item_title()) ; ?>”>
<img src=”<?php echo osc_current_web_theme_url(‘images/no_photo.gif’); ?>” title=”” alt=”<?php echo osc_esc_html(osc_item_title()) ; ?>” width=”<?php echo $size[0]; ?>” height=”<?php echo $size[1]; ?>”>
</a>
</div>
<?php } ?>
<?php
…
}
?>
<?php } ?>
BUT IF WE DID LIKE ABOVE WE’D FIND THE SAME IMAGE FOR EACH ITEM. THIS IS HAPPENED BECAUSE WE FORGET TO CLEAR THE ‘resources’ KEY FROM THE PREVIOUS ITEM!!!. SO DO LIKE THIS:
<?php foreach($payments as $pay) { ?>
<?php
if(View::newInstance()->_exists(‘item’))
View::newInstance()->_erase(‘item’);
if(View::newInstance()->_exists(‘resources’))
View::newInstance()->_erase(‘resources’);
$itemId=$pay[‘fk_i_item_id’];
if($itemId != 0){
View::newInstance()->_exportVariableToView(“item”, Item::newInstance()->findByPrimaryKey($itemId));
…
?>
View::newInstance()->_erase(‘resources’) WILL CLEAR THE PREVIOUS ‘resources’ KEY, SO ‘osc_count_item_resources’ function WOULD LOAD THE NEW ONE. PLS SEE ‘osc_count_item_resources’ function code in /oc-includes/osclass/helpers/hItems.php
ref:/plugins/payment/user/user-payment-list.php
link:http://localhost/Projects/kokopage/index.php?page=custom&route=user-payment-list-url

30. When we use ‘osc_redirect_to’ function, sometime we get some warning:
‘Warning: Cannot modify header information – headers already sent by…’
then we use ‘header’ instead. I THINK WE STILL CAN USE ‘osc_redirect_to’ function by adding ‘ob_get_clean()’ function on the previous line like this: (TODO: NEED TEST!!!)
…
// HACK : This will make possible use of the flash messages 😉
ob_get_clean();
osc_add_flash_ok_message(__(‘Congratulations, the plugin is now configured’, ‘cookie’), ‘admin’);
osc_redirect_to(osc_route_admin_url(‘cookie-conf’));
ref:/plugins/cookies/admin/conf.php

31. IS A CUSTOM HOOK BEHAVIOUR LIKE GLOBAL FUNCTIONS????? IT CAN BE CALLED FROM ANYWHERE???

32. Customized get latest Items
View::newInstance()->_exportVariableToView(‘items’, $osclassItems);
if(osc_is_home_page()) {
$latestSearch = new Search();
$latestSearch->limit (0, osc_get_preference(‘maxLatestItems@home’, ‘osclass’));
$latestItems = $latestSearch->getLatestItems();

View::newInstance()->_exportVariableToView(‘items’, $latestItems);
}
ref:/osclass_plugin_test/oc-content/plugins/carousel_for_osclass/carousel_detail.php

33. How to validate form input on the plugins (for plugin admin page also)
Register and enqueue ‘jquery-validate’ on the init hook like this:
ref:/osclass.3.5.9/oc-content/plugins/mb_auction/index.php
function mb_auction_load_js_css() {
…
osc_register_script(‘auction_js’, mb_auction_plugin_directory().’js/auction.js’, ‘jquery’);
osc_register_script(‘jquery-validate’, osc_base_url() . ‘oc-includes/osclass/assets/js/jquery.validate.min.js’, ‘jquery’);
osc_register_script(‘jquery-validate-additional’, mb_auction_plugin_directory().’js/additional-methods.min.js’, array(‘jquery’, ‘jquery-validate’,’jquery-ui’));

…
osc_enqueue_script(‘auction_js’);
osc_enqueue_script(‘jquery-validate’);
osc_enqueue_script(‘jquery-validate-additional’);

osc_enqueue_style(‘auctionCss’, mb_auction_plugin_directory().’css/style.css’);
}
then you can use it anywhere on your plugin:
ref:/osclass.3.5.9/oc-content/plugins/mb_auction/admin/manage.php
<script type=”text/javascript”>

OSCLASS PROBLEMS & SOLUTIONS :
1. Problem : homepage/admin show blank page
Solution : Put define(‘OSC_DEBUG’, true) ; in config.php and refresh browser. pls see the error/warning output
or chmod 777 -R the osclass directory
or check again config.php (at part REL_WEB_URL and WEB_PATH)

2. Problem : front page show “We are sorry for any inconvenience. MyPage is undergoing maintenance.”
Solution : go to admin page (/oc-admin) on the browser then Show more -> Tools -> Maintenance mode then click “Disable maintenance mode”
then refresh again the front page

3. Problem : Warning : cannot open ‘HTMLPurifier/Bootstrap.php’. failed to open in …..
Solution : May be you just renamed the directory of the osclass project and the osclass cache still intact. pls change back the directory name and refresh

4. Problem : The requested URL /index.php was not found on this server.(can’t open url-friendly page)
Solution : check again your .htaccess
if the root of osclass in a sub directory, so change from
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
Options -MultiViews
</IfModule>
to (for example)
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /Projects/motobroker/
RewriteRule ^index\.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /Projects/motobroker/index.php [L]
</IfModule>

5. Problem : Can’t open the plugin link. for example this link : http://motobroker.dev/oc-admin/index.php?page=plugins&action=renderplugin&route=mb-facebook-manage&section=facebook just open a blank content
Solution : Check another plugin for the same route name. for example in mb_auction, there is ‘mb-facebook-manage’ route. after searching in another plugin, there is a same route in get_my_listing plugin. Pls change/rename the route in one of the plugin.

6. Add/attach ‘image’ (also how many image can be attached) and/or add ‘Price’ was not displayed on the item post/edit page
Solution: There is a setting in admin page -> Listings -> Settings (or by url:http://localhost/Projects/osclass_plugin_test/oc-admin/index.php?page=items&action=settings)
Pls check on ‘Optional fields’ : ‘Attach Images’ and ‘Price’
To set how many image can be attached, pls fill the ‘Attach ### images per listing’

LEARN THIS!!
HOW ‘wallet_button’ function defined in /plugins/payment/functions.php CAN BE CALLED FROM /plugins/promote_ad/user/payment.php???
THE SAME CASE FOR ‘Paypal::button’ static function defined in /plugins/payment/payments/paypal/Paypal.php ??
THE SAME CASE FOR ‘StripePayment::button’ static function defined in /plugins/payment/payments/stripe/StripePayment.php ???
SOLUTION!!!
In /plugins/payment/index.php, THOSE FUNCTIONS ALREADY INCLUDED GLOBALLY! LIKE THIS:

SO WHEN THE payment PLUGIN IS LOADED, ANOTHER PLUGIN CAN CALL THE FUNCTION???
WHAT IS THE DIFFERENT WITH osc_add_hook(‘init’, ‘payment_load_lib’);???
OR osc_add_hook(osc_plugin_path(__FILE__).”_enable”, ‘payment_update_version’);???
