[zero-two]

i'm new to vbulletin and the hook system, hope i'm not doing mess :P.
i'm not sure but may be perhaps $userdata?
if i use that i get

Fatal error: Cannot use object of type vB_DataManager_User as array in /var/www/forum/hook.php on line 32

where hook.php is the script that sent the data to the other mysql db.
on that line i just say $udata[u_id]=$userinfo['userid']; where userinfo is just the passed array that contains userdata and udata is the new array wich need to be written.

perhaps this is a problem related in used reserved names like userdata , userinfo?

thanks for your assistance, much appreciated
