Overriding default behaviors
...
The solution is to use the following override of the MySQLCore class:
| Code Block |
|---|
<?php
class MySQL extends MySQLCore
{
public function __construct($server, $user, $password, $database, $newlink = false)
{
$this->_server = $server;
$this->_user = $user;
$this->_password = $password;
$this->_type = _DB_TYPE_;
$this->_database = $database;
$this->connect($newlink);
}
public function connect($newlink = false)
{
if (!defined('_PS_DEBUG_SQL_'))
define('_PS_DEBUG_SQL_', false);
if ($this->_link = mysql_connect($this->_server, $this->_user, $this->_password, $newlink) )
{
if (!$this->set_db($this->_database))
die(Tools::displayError('The database selection cannot be made.'));
}
else
die(Tools::displayError('Link to database cannot be established.'));
/* UTF-8 support */
if (!mysql_query('SET NAMES \'utf8\'', $this->_link))
die(Tools::displayError('PrestaShop Fatal error: no utf-8 support. Please check your server configuration.'));
return $this->_link;
}
}
?>
|
...
The last parameter forces the creation of a MySQL connection.
Example 2
| Code Block |
|---|
/*
* Create a cron task to make periodical database backup
*/
class AdminTab extends AdminTabCore{
public function ajaxProcess()
{
// Here we call the same thing as if we did the old way
// + with "if": maybe we want to limit its use to only adding backup
// note: find yourself a way to get the file link if you want to send it by mail!
if (isset($_REQUEST['addbackup']))
return $this->postProcess();
}
public function displayAjax()
{
if (sizeof($this->_errors) > 0)
{
// handle errors
// for example, send mail with all error msg
$content = '';
foreach($this->_errors as $errorMsg)
$content .= $errorMsg;
$lang = Configuration::get('PS_LANG_DEFAULT');
// here we send a mail to give the result of the process
// notice: you have to create template mails files
Mail::Send($lang, 'backuptaskdone', '[autobackup] report backup error', array('backup_link'=>)), $to);
}
else
{
// no error, but maybe we want a mail ?
if(Configuration::get('PS_NOTICE_SUCCEED_BACKUP'))
{
// fileAttachment available, see 9th param of Send() method in classes/Mail.php
// + we can add a condition "if (Configuration::get('PS_AUTOBACKUP_SEND_FILE'))"
Mail::Send($lang, 'backuptaskerror', '[autobackup] report backup error', array('vars to use in tpl'), $to);
}
}
return true;
}
}

| Code Block |

/*
* This override allows you to use ajax-tab.php to make any admin action.
* Use it for crontask for example
*/
class AdminTab extends AdminTabCore {
public function ajaxProcess()
{
return $this->postProcess();
}
}

Example 3
| Code Block |
|---|
/*
* With this override, you have a new Smarty variable called "currentController" available in header.tpl
* This allows you to use a different header if you are on a product page, category page or home.
*/
class FrontController extends FrontControllerCore {
public function displayHeader()
{
self::$smarty->assign('currentController', get_class($this));
return parent::displayHeader();
}
}
