在将产品添加到购物车时更改报价的价格：magento

Question

我想在将产品添加到购物车时更改产品价格。

怎么可能让我知道...

Answer 1

做到这一点的方法是添加一个观察该事件的观察者'sales_quote_add_item'：<events>&nbsp; &nbsp; <sales_quote_add_item>&nbsp; &nbsp; &nbsp; &nbsp; <observers>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <priceupdate_observer>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <type>singleton</type>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <class>mymodule/observer</class>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <method>updatePrice</method>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </priceupdate_observer>&nbsp; &nbsp; &nbsp; &nbsp; </observers>&nbsp; &nbsp; </sales_quote_add_item></events>观察者应具有执行以下操作的方法：public function updatePrice($observer) {&nbsp; &nbsp; $event = $observer->getEvent();&nbsp; &nbsp; $quote_item = $event->getQuoteItem();&nbsp; &nbsp; $new_price = <insert logic>&nbsp; &nbsp; $quote_item->setOriginalCustomPrice($new_price);&nbsp; &nbsp; $quote_item->save();}

您可以使用观察者类来收听checkout_cart_product_add_after，并使用产品的“超级模式”为报价项设置自定义价格。在您的/app/code/local/{namespace}/{yourmodule}/etc/config.xml中：<config>&nbsp; &nbsp; ...&nbsp; &nbsp; <frontend>&nbsp; &nbsp; &nbsp; &nbsp; ...&nbsp; &nbsp; &nbsp; &nbsp; <events>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <checkout_cart_product_add_after>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <observers>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <unique_event_name>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <class>{{modulename}}/observer</class>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <method>modifyPrice</method>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </unique_event_name>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </observers>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </checkout_cart_product_add_after>&nbsp; &nbsp; &nbsp; &nbsp; </events>&nbsp; &nbsp; &nbsp; &nbsp; ...&nbsp; &nbsp; </frontend>&nbsp; &nbsp; ...</config>然后在/app/code/local/{namespace}/{yourmodule}/Model/Observer.php中创建一个Observer类&nbsp; &nbsp; <?php&nbsp; &nbsp; &nbsp; &nbsp; class <namespace>_<modulename>_Model_Observer&nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; public function modifyPrice(Varien_Event_Observer $obs)&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $customPrice = Mage::getSingleton(’core/session’)->getCustomPriceCalcuation(); // Provide you price i have set with session&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $p = $obs->getQuoteItem();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $p->setCustomPrice($customPrice)->setOriginalCustomPrice($customPrice);&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }
