Неопределенный пользовательский индекс и переменные пользовательские функции

Таким образом, я получаю эти ошибки на пользовательском веб-сайте. Я не разработчик, но я должен исправить эти ошибки.

Notice: Undefined index: user in /var/server/pages/home.php on line 13

Notice: Undefined variable: customFunctions in /var/server/templates/header.tpl on line 44

Здесь код home.php и ниже, что я буду атаковать header.tpl

     <?php
    session_start();    

    $cart = $_SESSION['cart'];

    if(!is_object($cart)) {
        $cart = new ShoppingCart();
    }


    $user = $_SESSION['user'];

    if(!is_object($user)) {
        $user = new User();
    }


    $mobileDetect = new MobileDetect();
    $deviceType = ($mobileDetect->isMobile() ? ($mobileDetect->isTablet() ? 'tablet' : 'phone') : 'computer');
    $bodyClass = '';


    if('computer' == $deviceType) {
        $bodyClass = 'body-computer';
    }
    else {
        $bodyClass = 'home';
    }



    $collectionDb = new CollectionDB();
    $collection = array();

    $collection = $collectionDb->getLastCollection();

    if(!empty($collection)) {
        $collectionTitle = $collection[0]['collection_title_'.$language];
        $collectionImage = $collection[0]['collection_image'];
    }


    require_once('templates/home.tpl');
?>

Здесь код header.tpl

Заранее спасибо.
