addCategoryFilter在Magento中根本不起作用

Question

我有一個名爲「New」的類別，其中有14個產品。

我使用Mage::getModel('catalog/category')->load(6);加載此類別（6是管理員中的ID）。

如果我打電話給echo $category->getProductCount();它正確顯示14（該類別中的產品數量）。現在

，我抓住了從產品類別與

$products = Mage::getModel('catalog/product') 
    ->setStoreId(Mage::app()->getStore()->getId()) 
    ->getCollection() 
    ->addAttributeToFilter('visibility', $visibility) 
    ->addCategoryFilter($category) 
    ->addAttributeToSelect("*") 
    ->setOrder('name','asc'); 

顯示這些產品的所有14，然後用一個簡單的循環foreach()，但是當我通過$products對象循環，它實際上回報所有我的產品。

我使用的版本是1.6.2.0，並且我清除了緩存。

有沒有人有一個原因，這是行不通的？

調用echo (string) $products->getSelect();回報

SELECT `e`.*, IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) AS `visibility`, `cat_index`.`position` AS `cat_index_position`, IF(at_name.value_id > 0, at_name.value, at_name_default.value) AS `name` FROM `catalog_product_entity` AS `e` INNER JOIN `catalog_product_entity_int` AS `at_visibility_default` ON (`at_visibility_default`.`entity_id` = `e`.`entity_id`) AND (`at_visibility_default`.`attribute_id` = '95') AND `at_visibility_default`.`store_id` = 0 LEFT JOIN `catalog_product_entity_int` AS `at_visibility` ON (`at_visibility`.`entity_id` = `e`.`entity_id`) AND (`at_visibility`.`attribute_id` = '95') AND (`at_visibility`.`store_id` = 1) INNER JOIN `catalog_category_product_index` AS `cat_index` ON cat_index.product_id=e.entity_id AND cat_index.store_id=1 AND cat_index.category_id='13' AND cat_index.is_parent=1 LEFT JOIN `catalog_product_entity_varchar` AS `at_name_default` ON (`at_name_default`.`entity_id` = `e`.`entity_id`) AND (`at_name_default`.`attribute_id` = '65') AND `at_name_default`.`store_id` = 0 LEFT JOIN `catalog_product_entity_varchar` AS `at_name` ON (`at_name`.`entity_id` = `e`.`entity_id`) AND (`at_name`.`attribute_id` = '65') AND (`at_name`.`store_id` = 1) WHERE (((IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) = '4') OR (IF(at_visibility.value_id > 0, at_visibility.value, at_visibility_default.value) = '2'))) ORDER BY `name` as

時簡化它的工作對我來說：

$cat = Mage::getModel('catalog/product')->setId(198); 

$products = Mage::getModel('catalog/product') 
    ->getCollection() 
    ->addCategoryFilter($cat) 
    ->addAttributeToSelect("*") 
    ->setOrder('name','asc') 
    ->load(); 

foreach($products as $p) { 
    print_r($p->getSku().PHP_EOL); 
} 

順便說一句，SQL更具可讀性（對我來說，反正）如果您在getCollection之後立即放置addAttributeToSelect調用。
