仅比较那些具有相同类别magento的产品
问题描述：
我只想比较那些具有相同父级的类别，
i want to compare only those category who have same parent,
例如， 用户可以将诺基亚手机与三星手机进行比较 但是如果用户想将诺基亚手机与鞋子进行比较，则不允许比较这些产品
for Example, user can compare nokia mobile with samsung mobile but if user want to compare nokia mobile with shoes than it will not allow to compare those products
给予了极大的帮助
先谢谢您

在app \ code \ core \ Mage \ Catalog \ controllers \ Product \ CompareController.php \中进行如下更改
In app\code\core\Mage\Catalog\controllers\Product\CompareController.php\ make changes like the following
if ($product->getId() /* && !$product->isSuper() */ ) {
$categoryIds = $product->getCategoryIds();
if (is_array($categoryIds) and count($categoryIds) > 1) {
$cat = Mage::getModel('catalog/category')->load($categoryIds[2]);
if(!isset($_SESSION['compare']))
{
$_SESSION['compare']=$cat->getId();
$_SESSION['comparecount']=0;
}
if($cat->getId() == $_SESSION['compare'] /* || $cat->getId() == 13 ||$cat->getId() == 18 ||$cat->getId() == 35*/ ) ///come back here
{
$_SESSION['comparecount']++;
Mage::getSingleton('catalog/product_compare_list')->addProduct($product);
Mage::getSingleton('catalog/session')->addSuccess(
$this->__('The product %s has been added to comparison list.:)', Mage::helper('core')->escapeHtml($product->getName()))
);
Mage::dispatchEvent('catalog_product_compare_add_product', array('product'=>$product));
}else
{
Mage::getSingleton('catalog/session')->addSuccess(
$this->__('The product %s not possible to add in comparison list.:(', Mage::helper('core')->escapeHtml($product->getName()))
);
}
}}
//// Same file in function removeAction() after condition
if($item->getId()) {
$item->delete();
/// add the following lines
$_SESSION['comparecount']--;
if($_SESSION['comparecount']<1) { unset($_SESSION['comparecount']); unset($_SESSION['compare']); }
//// Same file in function clearAction() after try { $items->clear();
//// add the following lines
unset($_SESSION['compare']);
