Question

我正在使用magneto 1.6，我正在尝试使用本地池中的自定义控制器重写核心Onepagecontroller。

它的工作到目前为止，但是当我安装其他支付模块时，也使用自定义Onepagecontroller，＆＃39;它不能正常工作＆＃39;。

Magneto没有读取我的自定义OnepageController，磁铁只是从其他模块读取自定义OnepageController

这是我的文件结构和代码：

我的自定义OnepageController： \ app \ code \ local \ Sprint \ Migs \ controllers \ Checkout \ OnepageController.php

config.xml文件： \ app \ code \ local \ Sprint \ Migs \ etc \ config.xml

    <?xml version="1.0"?>

这是我的自定义单页控制器

Answer 1

您在config.xml中做得很好，但最好删除结帐时的<use>standard</use>节点。

另外，您是否在课前要求原始控制器？它应该是这样的：

<?php

require_once Mage::getModuleDir('controllers', 'Mage_Checkout') . DS . 'OnepageController.php';

class Sprint_Migs_Checkout_OnepageController 
           extends Mage_Checkout_OnepageController
{
    /* Your New / Overrided Functions */
}

Answer 2

问题解决了，我使用观察者事件也捕获自定义字段并保存到自定义表

但我只是想知道，使用观察者事件和覆盖一个页面控制器之间有什么不同？

自定义单页控制器不会覆盖
