以编程方式将捆绑产品添加到购物车 Magento

Question

所以我有一个捆绑产品，其中包含 6 个产品。我已经编写了将此捆绑包添加到购物车的代码，以编程方式将所有 6 个选项添加到捆绑包中……但我得到了这个 Call to a member function getPosition() on a non-object 错误……它发生在 shakeSelections 函数中，但它不会感觉是因为所有的对象和东西都需要去，比如$a和$b需要是Mage_Catalog_Model_Product数据类型，它们只是getOption方法在其中不存在......有什么我做错了吗？

这是我的自定义控制器中的自定义 addAction：

public function addAction() {
        $prdId = $this->getRequest()->getParam('product');

        $cart = Mage::getModel('checkout/cart');
        $cart->init();

        $_return = array('code' => 0, 'message' => 'Something went wrong...');

        if (!empty($prdId)) {
            $product = new Mage_Catalog_Model_Product();
            $product->load($prdId);

            if ($product->getTypeId() == Mage_Catalog_Model_Product_Type::TYPE_BUNDLE) {
                $typeInstance = $product->getTypeInstance(true);
                $optionCollection = $typeInstance->getOptionsCollection($product);

                $selectionCollection = $typeInstance->getSelectionsCollection(
                    $typeInstance->getOptionsIds($product),
                    $product
                    );

                $this->_options = $optionCollection->appendSelections($selectionCollection, false,
                    Mage::helper('catalog/product')->getSkipSaleableCheck()
                    );

                $bundle_option = array();

                foreach ($this->_options as $key => $value) {
                    foreach ($value['selections'] as $selKey => $selection) {
                        $bundle_option[$selection->option_id][] = $selection['selection_id'];
                    }
                }

                $params = array(
                    'product' => $prdId,
                    'related_product' => '',
                    'bundle_option' => $bundle_option,
                    'qty' => '1',
                );

                $cart->addProduct($product, $params);
                $cart->save();
            }
        }
    }

url 基本上是：/forty/cart/add/product/11 其中 11 是捆绑产品的 id。

这里应该对你的代码进行一些修改

$cart = Mage::getModel('checkout/cart');
$cart->init();

$params = $this->getRequest()->getParams();
$productId = $this->getRequest()->getParam('product');

$product = Mage::getModel('catalog/product')->setStoreId(Mage::app()->getStore()->getId())->load($productId);

if($product->getTypeId() == "bundle"){

    $bundled_items = array();
    $optionCollection = $product->getTypeInstance()->getOptionsCollection();
    $selectionCollection = $product->getTypeInstance()->getSelectionsCollection($product->getTypeInstance()->getOptionsIds());
    $options = $optionCollection->appendSelections($selectionCollection);

    foreach($options as $option) {
        $_selections = $option->getSelections();

        foreach($_selections as $selection) {
            $bundled_items[$option->getOptionId()][] = $selection->getSelectionId();
        }
    }

    $params = array('bundle_option' => $bundled_items,'qty' => 1,'product'=>$productId);
}

if (isset($params['qty'])) {
    $filter = new Zend_Filter_LocalizedToNormalized(
        array('locale' => Mage::app()->getLocale()->getLocaleCode())
        );
    $params['qty'] = $filter->filter($params['qty']);
}

$product = new Mage_Catalog_Model_Product();
$product->load($productId);

$cart->addProduct($product, $params);
$cart->save();

Mage::dispatchEvent('checkout_cart_add_product_complete',
    array('product' => $product, 'request' => $this->getRequest(), 'response' => $this->getResponse())
);

希望这对你有用。
