Magento:将捆绑中的简单产品添加到购物车中的单独行

My client is requesting that each simple product within a bundled product they are selling (Clothing Top and Bottom) be added as a separate line item in the cart whenever a user adds it. Can anyone direct me in how to accomplish this? I am fairly good with MVC and the Zend Framework, but I need a bit of help finding the exact files that control adding bundled products to the cart, or an alternate method for getting these items added separately. Please assume that the only possible product type for this clothing is the Bundled product type.

你需要一个观察者:

    <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);
        }
   }

只是一个简单的示例，但可能会有所帮助.

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

$oProduct->load($vProductId);

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

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

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

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

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

            }
}

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

/**
 * @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
        }
    }
}
