Question

我已经覆盖了本地文件夹中的 CompareController.php 但是没有工作，那么我重命名我的控制器和magento的核心 CompareController.php 控制器，但是addtocompare功能正在运行

<?php

//notice that require_once is calling **CompareController.php** under the Product directory
    require_once(Mage::getModuleDir('controllers','Mage_Catalog').DS.'Product'.DS.'CompareController.php');

class Company_Catalog_Product_CompareController extends Mage_Catalog_Product_CompareController
{
public function addAction() {

    if (!$this->_validateFormKey()) {
        $this->_redirectReferer();
        return;
    }

    $productId = (int) $this->getRequest()->getParam('product');

    $product = Mage::getModel('catalog/product')->setStoreId(Mage::app()->getStore()->getId())->load($productId);

    $categoryIds = $product->getCategoryIds();

    $productPresent = false;
    $found = array();
    $compareProducts = Mage::helper('catalog/product_compare')->getItemCollection();

    $itemCount = Mage::helper('catalog/product_compare')->getItemCount();


    if($itemCount) {
        $compareProductId = $compareProducts->getFirstItem()->getId();
        $compareProductCollection = Mage::getModel('catalog/product')->setStoreId(Mage::app()->getStore()->getId())->load($compareProductId);
        $compareProductCats = $compareProductCollection->getCategoryIds();

        foreach($categoryIds as $num) {
            if (in_array($num,$compareProductCats)) {
                $found[$num] = true;
            }
        }

        foreach($compareProducts as $products) {
            if($productId == $products->getId()) {
                $productPresent = true;
            }
        }

        //Check if categories of products to be compared are matching
        if(empty($found)){
            Mage::getSingleton('catalog/session')->addError(
                $this->__('You cannot compare %s with the items in the comparison list. Please select products from the same category.', Mage::helper('core')->escapeHtml($product->getName()))
            );
            $this->_redirectReferer();
            return;
        }            

    }

    //Add product in comparison list
    if ($productId && (Mage::getSingleton('log/visitor')->getId() || Mage::getSingleton('customer/session')->isLoggedIn())) {

        if ($product->getId()/* && !$product->isSuper()*/) {
            Mage::getSingleton('catalog/product_compare_list')->addProduct($product);
            Mage::getSingleton('catalog/session')->addSuccess(
                $this->__('The product %s has been added to the comparison list.', Mage::helper('core')->escapeHtml($product->getName()))
            );
            Mage::dispatchEvent('catalog_product_compare_add_product', array('product'=>$product));
        }

        Mage::helper('catalog/product_compare')->calculate();
    }

    $this->_redirectReferer();
}
}

您无法以这种方式覆盖控制器。 Magento类加载器不在控制器类的本地文件夹中查找。

但是你可以在你想要覆盖的控制器之前添加你自己的控制器的调用为此，您需要使用新控制器创建自己的模块，并在config.xml中添加以下行：

<config>
 ...
<frontend>
    <routers>
        <catalog>
            <args>
                <modules>
                    <MyModule_Compare before="Mage_Catalog">MyModule_Compare</MyModule_Compare>
                </modules>
            </args>
        </catalog>
    </routers>
</frontend>
...
</config>

如何比较magento中的同类产品？
