Fatal erro przy dodawaniu produktu do koszyka Prestashop 1.7

Recommended Posts

Witam, chciałbym stworzyc prosta funkcje dodajaca produkt o okreslonym atrybucie do koszyka, jednak w trakcie wykonywania ponizszego kodu, otrzymuje blad krytyczny znajdujacy sie ponizej, jednak mimo bledu, odswiezajac w innej karcie koszyk, produkt zostal dodany prawidlowy, ilosc, produkt i atrybut.

prosze o pomoc, w czym tkwi problem?


function addProductToCart($id, $productAttributeID)
    $context = Context::getContext();
    $id_cart = $context->cookie->__get('id_cart');

    $cart = new Cart($id_cart);

    $cart->updateQty(1, (int)$id, (int)$productAttributeID);



addProductToCart(41, 518);
