Question

我尝试通过此代码获取productsCollection：

    $collection = Mage::getModel('catalog/category')->getCollection();
/* @var $collection Mage_Catalog_Model_Resource_Eav_Mysql4_Category_Collection */
$collection->addAttributeToSelect('url_key')
    ->addAttributeToSelect('name')
    ->addAttributeToSelect('is_anchor')
    ->addAttributeToFilter('is_active', 1)
    ->addIdFilter(array(4,5))//$_categories)
    ->setOrder('position', 'ASC')
    ->joinUrlRewrite()
    ->load();

$productCollection = Mage::getResourceModel('catalog/product_collection');
$layer             = Mage::getSingleton('catalog/layer');
$layer->prepareProductCollection($productCollection);
$productCollection->addCountToCategories($collection);
foreach($productCollection as $product){
    print_r($product->getCategoryIds());
}

但是行addIdFilter（array（4,5））不起作用，我看到了所有产品，即使在某些类别中也没有。

有什么问题？

Answer 1

尝试使用逗号分隔的ID传递字符串：

->addIdFilter("4,5")

如果这不起作用，您可以尝试：

->addAttributeToFilter(’id’, array('in' => array(4,5)))

这对我有帮助：

        $collection = $category->getCollection();
    /* @var $collection Mage_Catalog_Model_Resource_Category_Collection */
    $collection->addAttributeToSelect('url_key')
        ->addAttributeToSelect('name')
        ->addAttributeToSelect('all_children')
        ->addAttributeToSelect('is_anchor')
        ->addAttributeToFilter('is_active', 1)
        ->addIdFilter($category->getChildren())
        ->setOrder('position', Varien_Db_Select::SQL_ASC)
        ->joinUrlRewrite()
        ->load();

Magento产品按类别划分
