My forum needs this hack but it didn't work as expected. I just fixed it and I'm sharing my code with you... I haven't tested it for performance or other installations...

Replace the content of the 'Required Attachment check' plugin to:

PHP Code:

if($type=='thread')
{
 
  $q = "
  SELECT r.forumid, IF(r.extensions LIKE concat( '%*', a.extension, '*%' ), '1', '0') AS ext
  FROM forumrequiredattachment r
  LEFT JOIN " . TABLE_PREFIX . "attachment a ON a.posthash = '" . $vbulletin->db->escape_string($post['posthash']) . "'
         AND a.userid = " . $vbulletin->userinfo['userid'] . "
  WHERE r.forumid ='" . $foruminfo['forumid'] . "'
        ORDER BY a.attachmentid
  ";
  $attachs = $vbulletin->db->query_first_slave($q);
  if(sizeof($attachs) > 0 and $attachs['ext'] == '0')
    $errors[] = $vbphrase['required_attachment_missing'];
}
