'Posts needing replies' widget

[ddrake]

I'm using a PHP direct execution widget to find "Posts Needing Replies". These are defined as visible, non-sticky posts in a specific set of forums with 0 replies. But some of the forums are not available to all users, so I want to modify the query to hide any posts that are not accessible by the current user. Can anyone help?

PHP Code:

ob_start();
  require_once('./includes/functions_user.php');
  require_once('./includes/functions_bigthree.php');
  // Get Popular Threads
  $need_replies_get = vB::$db->query_read("
    SELECT * FROM ".TABLE_PREFIX."thread
    WHERE visible=1 AND replycount=0 AND forumid in(9,10,12,15,16) AND sticky = 0
   ORDER BY replycount DESC
   LIMIT 5");
  $output_bits = '';
  while($need_replies = vB::$db->fetch_array($need_replies_get))
  {
        $output_bits .= '<a target="_self" href="showthread.php?t='.$need_replies[threadid].'">'.$need_replies[title].'</a><br />';
  }
  $output = $output_bits;
  ob_end_clean();

My problem is really just that I don't know how to get the id of the current user or a userinfo object from inside the PHP widget. I'm sure it's really simple, but I can't find an API for vb4...

Ok, after floundering a bit, this seems to work: vB::$vbulletin->userinfo['userid']
Please, anyone feel free to correct me if I'm making this harder than it needs to be...
