我有一个bundle product，它包含6个产品。我已经编写了代码将这个包添加到购物车中，以编程方式将所有6个选项添加到包中…但是我得到这个Call to a member function getPosition() on a non-object错误…它发生在shakeSelections函数中，但它没有意义，因为所有的对象和东西都需要去，像$a和$b需要是Mage_Catalog_Model_Product数据类型，它们是，它只是getOption方法不存在于其中…我做错什么了吗?
这是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基本为:/forty/cart/add/product/11其中11为绑定产品的id
您的代码中的一些修改应该是工作
$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())
);
希望这对你一定有用。
