从可配置的购物车中获取简单的产品 [英] Get Simple Product from Configurable in Cart

问题描述

我正在尝试加载已添加到客户购物车中的简单产品，但是当我检索这些项目时，它会显示可配置的父项.

I'm trying to load the simple products that have been added to a customer's cart, but when I retrieve the items, it's showing the parent configurable.

$cart = Mage::getSingleton('checkout/cart');
$productIds = array();

foreach ($cart->getQuote()->getAllVisibleItems() as $item) {
    $productIds[] = $item->getProduct()->getId();
}

var_dump($productIds);

例如，当我在购物车中添加了小号，中号和大号时，它将返回所有相同的可配置ID.如何获得单个简单产品?我正在尝试检索在简单产品级别设置的属性值.

For instance, this will return all the same configurable id when I've added a small, medium, and large to my cart. How can I get the individual simple products? I'm trying to retrieve an attribute value that's set on the simple product level.

推荐答案

查看了Magento如何在结帐/购物车页面上渲染购物车中的商品后，我可以在app/code/core/Mage/Checkout/Block/Cart/Item/Renderer/Configurable.php

After taking a look at how Magento renders the items in your cart on the checkout/cart page, I was able to find this in app/code/core/Mage/Checkout/Block/Cart/Item/Renderer/Configurable.php

/**
 * Get item configurable child product
 *
 * @return Mage_Catalog_Model_Product
 */
public function getChildProduct()
{
    if ($option = $this->getItem()->getOptionByCode('simple_product')) {
        return $option->getProduct();
    }
    return $this->getProduct();
}

因此，将其应用于问题中的代码段，

So, applying it to the snippet in the question, it would be

foreach ($cart->getQuote()->getAllVisibleItems() as $item) {
    $productId = $item->getProduct()->getId();
    if ($option = $item->getOptionByCode('simple_product')) {
        $productId = $option->getProduct()->getId();
    }
    $productIds[] = $productId;
}
