How to use datamanager to post as Guest ?

[memic4]

Hi,
How can I insert guest posts from a non-vb page using datamanager? (guest posting is enabled from cp)

At the moment I use the following code (and it works) to add posts to a thread but only for registered users:

PHP Code:

.........

// TDM Settings
    $tdm =& datamanager_init('Post', $vbulletin, ERRTYPE_ARRAY, 'threadpost');
            
    $tdm->set('userid', $user_id); 
    $tdm->set('pagetext', $text);
    $tdm->set('allowsmilie', 1);
    $tdm->set('visible', 1);
    $tdm->set('threadid', $thread_id);
    $tdm->set('dateline', $date);
    $id = $tdm->save();
        
    // rebuild  counters
    build_thread_counters($thread_id);
    build_forum_counters($forum_id);

    return $id; 


Thanks
