【问题描述】：
我遇到了无法解决的问题。部分原因是我无法用正确的术语来解释它。我是新手，很抱歉这个笨拙的问题。
您可以在下面看到我的目标概览。
我正在使用 Magento CE 1.7.0.2。
管理面板 -> 促销 -> 购物车价格规则 -> 添加新规则 -> 操作（选项卡）
在使用以下信息更新价格对于应用下拉菜单，我想添加我的自定义选项。
我该怎么做。
如何在不影响核心功能的情况下做到这一点...
我对此进行了一些研究，但从未找到任何关于覆盖促销的文章。
开始覆盖核心文件，我发现我应该覆盖以下内容。
- /app/code/core/Mage/Adminhtml/Block/Promo/Quote/Edit/Tab/Actions.php
- /app/code/core/Mage/SalesRule/Model/Rule.php
- /app/code/core/Mage/SalesRule/Model/Validator.php
在我的本地代码池中创建了类似Mage1/AdminhtmlMage1/SalesRule
我的新模块文件夹结构
- /app/code/local/Mage1/Adminhtml/Block/Promo/Quote/Edit/Tab/Actions.php
- /app/code/local/Mage1/SalesRule/Model/Rule.php
- /app/code/local/Mage1/SalesRule/Model/Validator.php

Rule.php
const TO_PERCENT_ACTION = 'to_percent';
const BY_PERCENT_ACTION = 'by_percent';
const TO_FIXED_ACTION = 'to_fixed';
const BY_FIXED_ACTION = 'by_fixed';
const CART_FIXED_ACTION = 'cart_fixed';

const GET_PERCENT_X_MAX_Y_ACTION = 'get_x_max_y';
Validator.php
public function process(Mage_Sales_Model_Quote_Item_Abstract $item) {
Mage::log('I'm Inside Process Function');
switch ($rule->getSimpleAction()) {
case Mage_SalesRule_Model_Rule::GET_PERCENT_X_MAX_Y_ACTION:
Mage::log('Helllll..');
break;
}
}
由于 Actions.php 和 Rule.php 文件编辑，我应该在下拉菜单中获得一个新选项，但我什么也没得到。我在这里做错了什么。
我希望 XML 文件中缺少一些东西。
有什么想法吗？
请帮帮我...
