Question

我有一个名为“New”的类别，其中包含14个产品。

我正在使用Mage::getModel('catalog/category')->load(6);加载此类别（6是管理员中的ID）。

如果我致电echo $category->getProductCount();，它会正确显示14（此类别中的产品数量）。

现在，我正在使用

从类别中抓取产品

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

显示所有这14个产品，然后使用简单的foreach()循环，但当我遍历$products对象时，它实际上会返回我的所有产品。

我正在使用1.6.2.0版，我已经清除了缓存。

有没有人有理由不这样做？

修改

调用echo (string) $products->getSelect();返回

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

当简化为：

时，它适用于我

$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);
}

顺便说一句，如果你在getCollection之后立即调用addAttributeToSelect，那么SQL对我来说更具可读性。

addCategoryFilter在Magento中根本不起作用
