问题描述
我想以编程方式将产品添加到购物车.另外,我想在添加到购物车时更改产品价格.
I want to add a product to cart programmatically. Also, I want to change the product price when added to cart.
假设我的产品价格是 100 美元.我想在添加到购物车时将其更改为 90 美元.
Suppose, my product's price is $100. I wanted to change it to $90 when added to cart.
我将产品添加到购物车.但是,我无法更改产品价格.
I added product to cart. However, I am unable to change the product price.
有可能吗?
这是将产品添加到购物车的代码:-
Here is the code to add product to cart:-
$cart = Mage::getSingleton('checkout/cart'); try { $cart->addProduct($product, array('qty' => 1)); $cart->save(); } catch (Exception $ex) { echo $ex->getMessage(); }
推荐答案
深入 Magento 的核心代码后,我发现你需要使用 $item->getProduct()->setIsSuperMode(true) 以使 $item->setCustomPrice() 和 $item->setOriginalPrice() 工作.
After digging a bit into Magento's core code, I found that you need to use $item->getProduct()->setIsSuperMode(true) in order to make $item->setCustomPrice() and $item->setOriginalPrice() work.
这里有一些示例代码,您可以在监听 checkout_cart_product_add_after 或 checkout_cart_update_items_after 事件的观察者中使用.代码在逻辑上是相同的,除了 checkout_cart_product_add_after 只为一件商品调用,checkout_cart_update_items_after 为购物车中的所有商品调用.此代码仅作为示例被分离/复制为 2 个方法.
Here is some sample code you can use within an Observer that listens for the checkout_cart_product_add_after or checkout_cart_update_items_after events. The code is logically the same except checkout_cart_product_add_after is called for only one item and checkout_cart_update_items_after is called for all items in the cart. This code is separated/duplicated into 2 methods only as an example.
/** * @param Varien_Event_Observer $observer */ public function applyDiscount(Varien_Event_Observer $observer) { /* @var $item Mage_Sales_Model_Quote_Item */ $item = $observer->getQuoteItem(); if ($item->getParentItem()) { $item = $item->getParentItem(); } // Discounted 25% off $percentDiscount = 0.25; // This makes sure the discount isn't applied over and over when refreshing $specialPrice = $item->getOriginalPrice() - ($item->getOriginalPrice() * $percentDiscount); // Make sure we don't have a negative if ($specialPrice > 0) { $item->setCustomPrice($specialPrice); $item->setOriginalCustomPrice($specialPrice); $item->getProduct()->setIsSuperMode(true); } }
事件:checkout_cart_update_items_after
/** * @param Varien_Event_Observer $observer */ public function applyDiscounts(Varien_Event_Observer $observer) { foreach ($observer->getCart()->getQuote()->getAllVisibleItems() as $item /* @var $item Mage_Sales_Model_Quote_Item */) { if ($item->getParentItem()) { $item = $item->getParentItem(); } // Discounted 25% off $percentDiscount = 0.25; // This makes sure the discount isn't applied over and over when refreshing $specialPrice = $item->getOriginalPrice() - ($item->getOriginalPrice() * $percentDiscount); // Make sure we don't have a negative if ($specialPrice > 0) { $item->setCustomPrice($specialPrice); $item->setOriginalCustomPrice($specialPrice); $item->getProduct()->setIsSuperMode(true); } } }
