[EXCHANGE]

I changed the Code a little bit.
The Thread titles now are only displayed to users who can view the forum the last post is in.

PHP Code:

//start get last thread title from forums
        $lastposttitle = $DB_site->query("SELECT title FROM thread WHERE forumid='$forum[forumid]' ORDER BY lastpost DESC");
        $lastposttitle = $DB_site->fetch_array($lastposttitle);
        $lastposttitle = $lastposttitle[title];
        $has_access=getpermissions($forum[forumid]);
        if (!$has_access['canview']) {
            $lastposttitle='';
        }
        else
        {
            if (strlen($lastposttitle) > 20) {
               $lastposttitle = substr($lastposttitle,0,18);
               $lastposttitle .= "..";
               }
        }
        //end get last thread title from forums
