我写了一个Prestashop的自定义控制器。可以完成一个简单的任务：1.如果尚未创建新购物车（工作正常）2.从数据库获取属性ID（工作正常）3.分配自定义（一个文本字段）4.添加此产品购物车。

我当前的代码：

$idProduct = 1; // for me it's always one
$qty= 1; // always add one item

// get cart id if exists
if ($this->context->cookie->id_cart)
{
    $cart = new Cart($this->context->cookie->id_cart);
}

// create new cart if needed
if (!isset($cart) OR !$cart->id)
{
    $cart = new Cart();
    $cart->id_customer = (int)($this->context->cookie->id_customer);
    $cart->id_address_delivery = (int)  (Address::getFirstCustomerAddressId($cart->id_customer));
    $cart->id_address_invoice = $cart->id_address_delivery;
    $cart->id_lang = (int)($this->context->cookie->id_lang);
    $cart->id_currency = (int)($this->context->cookie->id_currency);
    $cart->id_carrier = …
