There is a security issue with this hack. I won't release the detail just yet, but here is what mine currently looks like:

PHP Code:

if ($bbuserinfo['userid'] > 0 and $_GET['styleid'] > 0) {
        $newstyleset = intval($_GET['styleid']);
        if ($allowchangestyles==1) {
                        $DB_site->query("UPDATE session SET styleid='$newstyleset' WHERE sessionhash='".addslashes($session['dbsessionhash'])."'");
                        $DB_site->query("UPDATE user SET styleid='$newstyleset' WHERE userid='$bbuserinfo[userid]' LIMIT 1");
                        vbsetcookie("bbstyleid","",1);
        }
          standardredirect("Style settings have been updated.", $bburl);
        exit;
} 


There extra code is how vB itself deals with changing styles i.e. expiring the style cookie and updating the sessions table.
