You will need to select the vBulletin database after the code for the advert script is done.

Thats the php function you will need. If you are working with a page that includes vbulletin's global.php you would use this instead:

PHP Code:

$DB_site->select_db($dbname); 


or in vBulletin 3.5:

PHP Code:

$db->select_db($dbname);
