Question

我想得到:

当前用户购物车中的所有产品变体 ID；

产品变体的价格；

图片;

标题；

我有以下几点:

$store_id = 1;
    $order_type = 'default';
    $entity_manager = \Drupal::entityManager();
    $cart_manager = \Drupal::service('commerce_cart.cart_manager');
    $cart_provider = \Drupal::service('commerce_cart.cart_provider');
    $store = $entity_manager->getStorage('commerce_store')->load($store_id);

    $cart = $cart_provider->getCart($order_type, $store);

    if(isset($cart)){
        $itemNum = count($cart->getItems());
        ($itemNum > 0) ? $variables['items_in_cart'] = $itemNum : '';
    }

        $cart .= 'Subtotal: '.$cart->getSubtotalPrice();
        $cart .= '<br>Total price: '.$cart->getTotalPrice();
        $cart .= '<br>Created: '.$cart->getCreatedTime();
        $cart .= '<br>Customer id: '.$cart->getCustomerId();
        $cart .= '<br>Email: '.$cart->getEmail();
        $cart .= '<br>IP address: '.$cart->getIpAddress();
        $cart .= '<br>Item num. in cart: '.$itemNum;

您需要加载 Product store, cart and variation entity , 您需要从加载的产品中获取产品变体 ID，然后提取 Order ID for the current user, All product variation ID from the current users cart, Prices for Product variations, Images, Titles .

$product_variation = $event->getEntity();
$current_store = \Drupal::service('commerce_store.current_store');
$store = $current_store->getStore();
$cart_provider = \Drupal::service('commerce_cart.cart_provider');
$cart = $cart_provider->getCart("default", $store);

    foreach ($cart->getItems() as $order_item) {
        $productType = $order_item->getPurchasedEntity()->get('type')[0]->get('target_id')->getValue();
           // ksm("Order Item", $order_item);
           // For getting custom and variation field value.
           //$field_custom_value = $product_variation->get('field_custom_value')[0]->get('target_id')->getValue();
              $order_no = $order_item->get('purchased_entity')[0]->get('target_id')->getValue();
               ksm("Order No", $order_no);
              $order_no_id = $order_item->get('order_item_id')[0]->get('value')->getValue();
               ksm("Order No Id", $order_no_id);

    }
