将产品添加到购物车之前的Magento活动

Question

我想根据客户选择的选项计算价格.例如,有两个可配置的属性length,width

在将产品添加到购物车之前,我想根据选定的长度和宽度修改价格

$finalPrice=$rrp+($length*$width)

有没有可用于实现此目的的活动？

Answer 1

我会看catalog_product_get_final_price,并举例说明Mage_CatalogRule_Model_Observer::processFrontFinalPrice().请注意,在此事件之后处理基于选项的定价; 看到Mage_Catalog_Model_Product_Type_Price::getFinalPrice()和Mage_Catalog_Model_Product_Type_Configurable_Price::getFinalPrice().

请记住,定制此功能需要对不同的报价状态,客户状态,产品类型等进行大量测试.例如,考虑首次添加到购物车中的产品,然后从购物车更新其数量.通常有必要在几个方法/观察者中实现逻辑来处理所有排列.
