Magento：将捆绑中的简单产品添加到购物车中的单独行

我的客户要求，每当用户添加产品时，他们销售的捆绑产品（服装上衣和下装）中的每个简单产品都应作为单独的行项目添加到购物车中。谁能指导我如何实现这一目标？我对 MVC 和 Zend Framework 相当熟悉，但我需要一些帮助来找到控制将捆绑产品添加到购物车的确切文件，或者单独添加这些项目的替代方法。请假设该服装唯一可能的产品类型是捆绑产品类型。

您将需要一名观察员：

    <checkout_cart_product_add_after>
        <observers>
            <reporting>
                <type>singleton</type>
                <class>Yourcompany_yourmodelname_Model_Observer</class>
                <method>onCartProductAdd</method>
            </reporting>
        </observers>
    </checkout_cart_product_add_after>

然后做观察者：

class ourcompany_yourmodelname_Model_Observer extends Mage_Core_Model_Abstract
{
    /**
     * Binds to the checkout_cart_product_add_after Event and passes control to the helper function to process the quote
     *
     * @param Varien_Event_Observer $observer
     * @return void
     */
    public function onCartProductAdd($observer){
        $product = $observer->getProduct();
        $isProductBundle = ($product->getTypeId() == 'bundle');
        $items_to_add = array();
        $oTypeInstance = $oProduct->getTypeInstance(true);
        $aSelections = $oTypeInstance->getSelectionsCollection($aOptionIds, $product );
        $aOptions = $oTypeInstance->getOptionsByIds($aOptionIds, $product);
        $bundleOptions = $aOptions->appendSelections($aSelections, true);
        foreach ($bundleOptions as $bundleOption) {
            if ($bundleOption->getSelections()) {
                $bundleSelections = $bundleOption->getSelections();    
                foreach ($bundleSelections as $bundleSelection) {
                       $items_to_add[] = $bundleSelection.getID();

               }

            }
       }
       insertExtractedProducts($items_to_add);
    }

     /**
     * Add extracted products into quote
     *
     * @param array $items_to_add
      */
    public function insertExtractedProducts($items_to_add){
        /**@var $cart Mage_Checkout_Model_Cart**/
        $cart = Mage::helper('checkout/cart')->getCart();
        $ids_to_add = array();
        foreach($items_to_add as $item_to_be_added){
            $ids_to_add[] = $item_to_be_added->getProductId();
        }
        $cart->addProductsByIDs($ids_to_add);
        $cart->save();
        Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
        }
   }

虽然只是一个简单的示例，但可能会有所帮助。

Bundled products can be complicated to understand, when working with it via code: Here is a sample image:

每个捆绑产品都有一对多选项，最终将链接到要添加到购物车捆绑中的产品。

Each Option consists of one to many Selections, which will be the linked products that will end up in the Shopping cart, under this bundled product. One Selection, can typically be set as the default, and will already be selected on the product page. More information can be found at this link on how to create and configure bundled products, because in this document, we will only discuss the programming side of it. The bundled product’s display page, will look like this:

单击“添加到购物车”后，它在购物车中可能看起来像这样： 捆绑样品

Sample Shampoo
1 x Moisturiser-125ml $29.95
Default Conditioner
1 x Moisturiser-60g $99.95

当通过代码询问该产品时，您可以像任何普通产品一样加载它：

$oProduct->load($vProductId);

加载后，您需要获取一个产品类型实例，以便您可以加载该产品类型的选项。

$oTypeInstance = $oProduct->getTypeInstance(true);

现在我们可以通过以下方式获取该产品的选项 ID 列表：

$oTypeInstance = $oProduct->getTypeInstance(true);

为了询问选择，我们将选项列表添加到集合中，然后获取选项集合以及它们各自的选择：

$aSelections = $oTypeInstance->getSelectionsCollection($aOptionIds, $oProduct );
$aOptions = $oTypeInstance->getOptionsByIds($aOptionIds, $oProduct);
$bundleOptions = $aOptions->appendSelections($aSelections, true);

现在我们有一个选项集合，每个选项都有一个选择集合。我们现在可以循环浏览选项，并查看它们的选择。

foreach ($bundleOptions as $bundleOption) {
            if ($bundleOption->getSelections()) {
                $bundleSelections = $bundleOption->getSelections();

                foreach ($bundleSelections as $bundleSelection) {
                     // get some data here
                     $vName = $bundleOption->getTitle();
               }

            }
}

要获取捆绑产品的必需选择产品列表，您可以使用以下代码：

$requiredChildren = $this->getChildrenIds($product->getId(),$required=true);

然后，您可以循环遍历 ID 数组并按 ID 加载产品，以获取有关这些产品的更多信息。

购物车中的捆绑产品

为了循环浏览购物卡中捆绑产品的选定选项，您可以使用如下内容：

/**
 * @var Mage_Bundle_Model_Product_Type
 */
$typeInstance = $this->getProduct()->getTypeInstance(true);

// get bundle options
$optionsQuoteItemOption =  $this->getItem()->getOptionByCode('bundle_option_ids');
$bundleOptionsIds = unserialize($optionsQuoteItemOption->getValue());
if ($bundleOptionsIds) {
    /**
    * @var Mage_Bundle_Model_Mysql4_Option_Collection
    */
    $optionsCollection = $typeInstance->getOptionsByIds($bundleOptionsIds, $this->getProduct());

    // get and add bundle selections collection
    $selectionsQuoteItemOption = $this->getItem()->getOptionByCode('bundle_selection_ids');

    $selectionsCollection = $typeInstance->getSelectionsByIds(
        unserialize($selectionsQuoteItemOption->getValue()),
        $this->getProduct()
    );

    $bundleOptions = $optionsCollection->appendSelections($selectionsCollection, true);
    foreach ($bundleOptions as $bundleOption) {
        if ($bundleOption->getSelections()) {
            $label = $bundleOption->getTitle()

            $bundleSelections = $bundleOption->getSelections();

            foreach ($bundleSelections as $bundleSelection) {                        
                    $sName = $bundleSelection->getName();
            }
            // some more code here to do stuff
        }
    }
}

此代码从报价项目捆绑产品中获取选项，然后获取集合中该产品的选项，然后找到“选定”选项选择。
