我从包含一些产品ID的extrenal网站收到请求。 在我的模块中,我尝试加载产品并将其添加到购物车。我用这段代码试了一下:
public function indexAction() {
$ids = explode(',', $this->getRequest()->getParam('products'));
Mage::log('ADDING PRODUCTS');
$cart = Mage::getModel('checkout/cart');
$cart->init();
$pModel = Mage::getSingleton('catalog/product');
//$cart->addProductsByIDs($ids);
foreach ($ids as $id) {
Mage::log('Loading: ' . $id);
$product = $pModel->load($id);
Mage::log('Loaded: ' . $product->getId());
try {
$cart->addProduct($product, array('qty' => '1'));
} catch (Exception $e) {
Mage::log($e);
continue;
}
}
$cart->save();
if ($this->getRequest()->isXmlHttpRequest()) {
exit('1');
}
$this->_redirect('checkout/cart');
}
我可以在system.log中看到它正确加载产品。但重定向后,我在我的购物车中有第二个产品两次。第一个缺失。使用$ cart-> addProductsByIDs($ ids)效果很好,但我不能再影响产品的数量了。
有人知道我做错了什么并给我一个提示吗?

我遇到了同样的问题,我通过在每个循环中加载产品模型来修复它:
public function AddMultipleItemsAction() {
$products = explode(',', $this->getRequest()->getParam('products'));
$quantities = explode(',', $this->getRequest()->getParam('quantities'));
$numProducts = count($products);
$cart = $this->_getCart();
for($i=0;$i<$numProducts;$i++) {
$product_id = $products[$i];
$quantity = $quantities[$i];
if ($product_id == '') continue;
if(!is_numeric($quantity) || $quantity <= 0) continue;
$pModel = Mage::getModel('catalog/product')->load($product_id);
if($pModel->getTypeId() == Mage_Catalog_Model_Product_Type::TYPE_SIMPLE) {
try {
$eventArgs = array(
'product' => $pModel,
'qty' => $quantity,
'additional_ids' => array(),
'request' => $this->getRequest(),
'response' => $this->getResponse(),
);
Mage::dispatchEvent('checkout_cart_before_add', $eventArgs);
$cart->addProduct($pModel, array('product'=>$product_id,'qty' => $quantity));
Mage::dispatchEvent('checkout_cart_after_add', $eventArgs);
Mage::dispatchEvent('checkout_cart_add_product', array('product'=>$pModel));
$message = $this->__('%s was successfully added to your shopping cart.', $pModel->getName());
Mage::getSingleton('checkout/session')->addSuccess($message);
} catch (Mage_Core_Exception $e) {
if (Mage::getSingleton('checkout/session')->getUseNotice(true)) {
Mage::getSingleton('checkout/session')->addNotice($pModel->getName() . ': ' . $e->getMessage());
}
else {
Mage::getSingleton('checkout/session')->addError($pModel->getName() . ': ' . $e->getMessage());
}
} catch (Exception $e) {
Mage::getSingleton('checkout/session')->addException($e, $this->__('Can not add item to shopping cart'));
}
}
}
$cart->save();
$this->_getSession()->setCartWasUpdated(true);
$this->_redirect('checkout/cart');
}
然后我有一个“将所有项目添加到购物车”按钮,该按钮执行以下Javascript代码:
<script type="text/javascript">
function addAllItemsToCart() {
productsArr = new Array();
quantitiesArr = new Array();
$$('#product-listing-table .qty').each(
function (input, index) {
productsArr[index] = encodeURIComponent(input.readAttribute('product_id'));
quantitiesArr[index] = encodeURIComponent(input.value);
}
);
var url = '/MyModule/Cart/AddMultipleItems/products/'+productsArr.join(',')+'/quantities/'+quantitiesArr.join(',')+'/';
setLocation(url);
}
为了能够工作,我在数量文本框中添加了额外的product_id属性,例如:
<input type="text" size="2" product_id="<?php echo $_product->getId();?>" name="productqty_<?php echo $_product->getId();?>" class="qty" />
并且整个产品列表位于ID product-listing-table
的div中答案 1 :(得分:1)
刚刚查看了我已经获得的一些自定义添加到购物车代码,并确认工作正常,我唯一的区别是:
$cart->addProduct($product, array(
'qty' => 1,
'product' => $product->getId(),
'uenc' => Mage::helper('core')->urlEncode(Mage::helper('core/url')->getCurrentUrl())
));
// Also make sure we know that the cart was updated
Mage::getSingleton('checkout/session')->setCartWasUpdated(true);
那就是说,你的错误并不会让你觉得你在这个区域遇到麻烦。我无法想象会是这样,但是每次将产品添加到购物车时,购物车模型是否可能需要save()
d?值得一试。
