PHP Code:

    if (defined('credit_SCRIPT')) {
        $vbulletin->options['selectednavtab'] = 'credit';
        
        $templater = vB_Template::create('credit_navbar_tab');
            $templater->register('links',$link);
        $template_hook['navtab_end'] .= $templater->render();
    } else {
        global $credit_active_items;
        require_once(DIR . '/credit/functions.php');
        
        $template_hook['navtab_end'] .= vB_Template::create('credit_navbar_tab')->render();
        
        if (is_array($credit_active_items[$vbulletin->userinfo['userid']])) {
            $items2show = fetchItemFromCache(
                $credit_active_items[$vbulletin->userinfo['userid']]
                , $vbulletin->credit['phpfile'] . '?do=myitems&itemid=%1$s#item%1$s'
                , 'itemid'
                , true
                , true
            );

            foreach ($items2show as $items2show_tmp) {
                foreach ($items2show_tmp as $item2show) {
                    $useHead = false;
                    $fulllink = $item2show['fulllink'];
                    $link = $item2show['link'];
                    $text = 
                        $item2show['name']
                        . iif($item2show['status_str'],' ' . $item2show['status_str'])
                        . iif($item2show['count'] > 1," x<strong style=\"color:red\">$item2show[count]</strong>");
                        
                    $templater = vB_Template::create('credit_navbar_popup_menu_bit');
                        $templater->register('useHead', $useHead);
                        $templater->register('fulllink', $fulllink);
                        $templater->register('link', $link);
                        $templater->register('text', $text);
                    $template_hook['credit_navbar_popup_menu_more'] .= $templater->render();
                }
            }
        }
        
        ($hook = vBulletinHook::fetch_hook('credit_navbar_popup_menu')) ? eval($hook) : false;
        
        $templater = vB_Template::create('credit_navbar_popup_menu_bit');
            $templater->register('useHead', false);
            $templater->register('fulllink', true);
            $templater->register('link', '#');
            $templater->register('text', $vbulletin->credit['name'] . ': ' . $vbulletin->userinfo['credit']);
        $template_hook['credit_navbar_popup_menu_more'] .= $templater->render();
        
        $templater = vB_Template::create('credit_navbar_link');
            $templater->register('template_hook',$template_hook);
        $template_hook['navbar_after_calendar'] .= $templater->render();
