if (empty($post_thanks_done))
{
$post_thanks_querys = $db->query("SELECT postid FROM ". TABLE_PREFIX ."post WHERE threadid = '$post[threadid]'");
    $post_thanks_postids = 0;
    
    while ($post_thanks_query = $db->fetch_array($post_thanks_querys))
    {
      $post_thanks_postids .= ",$post_thanks_query[postid]";
    }

    $post_thanks_cashe = $db->query("SELECT * FROM " .TABLE_PREFIX. "post_thanks WHERE postid IN ($post_thanks_postids) ORDER BY username ASC");
