WOL locations for sub-pages

[veenuisthebest]

I know how to create custom WOL locations but How do we create custom online locations for sub-pages like I want the exact location to display when user is viewing page.php?do=this&uid=12

For example, this is the WOL code of ibproarcade:-

Hook: online_location_unknown

PHP Code:

if ($userinfo['activity'] == 'arcade')
{
    $gameid =& $userinfo['gameid'];
    global $wol_games;
    $gametitle =& $wol_games["$gameid"];
    switch($userinfo['values']['do']) 
    {
        case 'play':
            $userinfo['action'] = $vbphrase['ibproarcade_playing_game'];
            $userinfo['where'] = '<a href="arcade.php?' . $vbulletin->session->vars['sessionurl'] . "do=play&amp;gameid=$gameid\">$gametitle</a>";
            break;
        case 'stats':
            $userinfo['action'] = $vbphrase['ibproarcade_viewing_highscores'];
            $userinfo['where'] = '<a href="arcade.php?' . $vbulletin->session->vars['sessionurl'] . "do=stats&amp;gameid=$gameid\">$gametitle</a>";
            break;
        default:
            $userinfo['action'] = $vbphrase['ibproarcade_viewing_home'];
            $userinfo['where'] = '<a href="arcade.php' . $vbulletin->session->vars['sessionurl_q'] . "\">$vbphrase[ibproarcade_home]</a>";
            break;
    }
    $handled = true;
DEVDEBUG("gameid = " . $userinfo['gameid']);
} 


Hook: online_location_process

PHP Code:

if (($filename == 'arcade.php') || ($filename == 'holdsession.php'))
{
    $userinfo['activity'] = 'arcade';
    if (!empty($values['gameid']))
    {
        $userinfo['gameid'] = intval($values['gameid']);
        global $gameids;
        $gameids .= ',' . $userinfo['gameid'];
    } 
} 


Can anybody explain me how its done? Thanks
