我正在做一个 magento 定制站点我需要将某些产品详细信息添加到数据库中，所以我在 Mage 结帐控制器中使用了函数 addAction()，为了使其成为一个模块，我必须覆盖 cartController 的 Addaction()
我已经引用了 stackoverflow 的最重要的控制器问题，但没有使用它使用 Mage 结帐控制器中的编码
我用过下面的代码，
code\local\SmartGrowth\CompatibleWith\etc
<?xml version="1.0" encoding="UTF-8"?>
<config>
<modules>
<SmartGrowth_CompatibleWith>
<version>0.1.0</version>
</SmartGrowth_CompatibleWith>
</modules>
<!-- Configure our module's behavior in the global scope -->
<global>
<blocks>
<catalog>
<rewrite>
<product_view>SmartGrowth_CompatibleWith_Block_CompatibleWith</product_view>
