if you still want it the way, it should work, try this:

PHP Code:

if ($permissions['canopenclose'] and (ismoderator($threadinfo[forumid],"canopenclose") or $isstarter=$DB_site->query_first("SELECT postuserid FROM thread WHERE threadid='$threadid' and postuserid='$bbuserinfo[userid]'")))  {
    $closethreadchecked=iif(trim($closethread)=="yes","checked","");
    eval("\$closethreadbox = \"".gettemplate("newpost_closethread")."\";");
  } else {
    $closethreadbox="";
  } 


it checks, if the user can open close own threads (and started this thread) or is moderator with this rights.
