默认情况下,当您加载产品集合时,您将获得有关产品的少量信息。前任:
Array
(
[entity_id] => 9
[entity_type_id] => 4
[attribute_set_id] => 4
[type_id] => simple
[sku] => DLKJFER343
[has_options] => 0
[required_options] => 0
[created_at] => 2012-12-07 16:04:58
[updated_at] => 2012-12-11 16:21:37
[cat_index_position] => 0
[stock_item (Varien_Object)] => Array
(
)
)
您需要明确告诉 Magento 加载额外信息或按如下值过滤:
$_productCollection = Mage::getResourceModel( 'catalog/product_collection' );
// Filter by enabled products
$_productCollection->addAttributeToFilter( 'status', 1 );
// Load all product information
$_productCollection->addAttributeToSelect( '*' );
$_productCollection->addCategoryFilter( $category );
现在你会看到这样的东西($_product->debug()
用来转储一些信息):
Array
(
[entity_id] => 3
[entity_type_id] => 4
[attribute_set_id] => 4
[type_id] => simple
[sku] => DLKJFER343
[has_options] => 0
[required_options] => 0
[created_at] => 2012-12-05 18:47:39
[updated_at] => 2012-12-11 16:20:25
[cat_index_position] => 0
[status] => 1
[visibility] => 4
[enable_googlecheckout] => 1
[tax_class_id] => 2
[is_recurring] => 0
[weight] => 3.0000
[price] => 534.2500
[name] => Sample Product
[url_key] => some-product
[is_returnable] => 2
[msrp_enabled] => 2
[msrp_display_actual_price_type] => 4
[image] => /w/r/something.png
[small_image] => /w/r/something_sm.png
[thumbnail] => /w/r/something_th.png
[options_container] => container2
[url_path] => some-product.html
[image_label] => One image label
[small_image_label] => Another image label
[thumbnail_label] => An image label
[description] => Long winded blah, blah, blah.
[short_description] => Blah, blah, blah.
[stock_item (Varien_Object)] => Array
(

)
媒体库信息(标签等)是一个不同的野兽,必须通过对象的getMediaGalleryImages()
方法专门请求Mage_Catalog_Model_Product
。
但是NULL
,如果在循环通过产品集合时调用此方法将返回。奇怪的是,如果不明确加载产品模型,您将无法访问这些数据(原因我不会在此回复中详细说明)。所以,我们需要尝试这样的事情:
$product = Mage::getModel( 'catalog/product' )->load( $_product->getId() );
$images = $product->getMediaGalleryImages();
但是,在您的收集循环中执行此操作会影响性能,所以要小心。
编辑:
Mage_Catalog_Block_Product->getLoadedProductCollection()
长,长,长话短说(这种方法深入挖掘)......据我所知 getLoadedProductCollection()
,只会显示已Used In Product Listing
设置为Yes
.
原因在于 Mage_Catalog_Model_Resource_Config ...
public function getAttributesUsedInListing()
{
// ... some code above omitted...
->where('main_table.entity_type_id = ?', (int)$this->getEntityTypeId())
// THIS RIGHT HERE IS WHY
->where('additional_table.used_in_product_listing = ?', 1);
return $adapter->fetchAll($select);
}
