Data Manager Programming Problems

You need to pass a valid vBulletin registry object to the datamanager; in your script, $vbulletin doesn't have the proper scope in your method.

Pass $vbulletin through the constructor:

PHP Code:

function codeigniter bridge(&$registry) {
    $this->registry =& $registry;
}

// *** .....

 $vb =& new codeigniter_bridge($vbulletin);
