prestashop获取订单的产品

Question

我从递送地址中获得了我想要的所有数据：

public function getOrderShippingCost($params, $shipping_cost)
    {
        global $smarty;
$url = Tools::getHttpHost(true).__PS_BASE_URI__;
$address = new Address($this->context->cart->id_address_delivery);
        $state = new State ($address->id_state);
        $country = new Country ($address->id_country);

echo $address->postcode;

        echo $address->country;

        echo $address->address1;

        echo $address->address2;

        echo $state->name;

        echo $country->iso_code;

结果很好，但是现在我如何才能获得订单的产品？

我尝试了下面的代码：

$products = $params['cart']->getProducts(true);

但是这样做的结果是Fatal error: Cannot use object of type Cart as array in

如果我尝试这样的东西：

$order = new Order($this->context->order->id_order);

结果是两个错误：

Notice: Undefined property: Context::$order in /var/www/prestashop/modules/mycarrier/mycarrier.php on line 325

Notice: Trying to get property of non-object in /var/www/prestashop/modules/mycarrier/mycarrier.php on line 325

怎样才能得到产品呢？

Answer 1

您已经在使用：

new Address($this->context->cart->id_address_delivery);

所以我认为你可以使用：

$products = $this->context->cart->getProducts(true);

Answer 2

您需要加载order detail对象来获取prestashop中特定订单id的产品。

$ProductDetailObject = new OrderDetail;
$product_detail = $ProductDetailObject->getList($order_id);
