I found the solution after all. Simply define _PS_ADMIN_DIR_
and init the config.inc.php
, Prestashop will automatically load the admin environment. However, if you are loading this from a module, its tricky to find the admin directory as its not defined anywhere, so I have written this small script.
$admindir = '';
foreach (glob("../../*/ajaxfilemanager", GLOB_ONLYDIR) as $filename) {
$admindir = str_replace('../../', '', $filename);
$admindir = str_replace('/ajaxfilemanager', '', $admindir);
}
define('_PS_ADMIN_DIR_', getcwd().'/../../'.$admindir);
require(_PS_ADMIN_DIR_.'/../config/config.inc.php');
Enjoy!
