Magentoのは、現在の動作方法であり、店舗の：私は1.6を使用していますし、場合には、それはあらゆる使用のだ、私はこのようなものを使用しています$ oStoreCollection-> addCategoryFilter（array（ '1'、 '2'））のようにstorecollectionからカテゴリを取得できます。
私はでここに見つけ、あなたを助けるかもしれない解決策に出くわした：次のようになり、
http://www.magentocommerce.com/boards/&/viewthread/201114/#t329230
彼らが使用するコードを： オーバーライドメイジ/カタログ/モデル/リソース/ EAV/Mysql4 /製品/コレクション、および以下のメソッドを追加：
$collection = Mage::getModel('catalog/product')->getCollection()
->addAttributeToSelect('*')
->distinct(true) // THIS IS WHAT YOU NEED TO ADD
->addCategoriesFilter($category->getAllChildren(true)); // Make sure you don't forget to retrieve your category here.
：それは、このように呼び出されます
