Question

我正在开一家只有可下载产品的商店。我需要获得每个客户的可下载产品，并能够按产品名称和sku对其进行排序。我当前的代码可用于检索所有下载链接。

$purchasedItems = Mage::getResourceModel('downloadable/link_purchased_item_collection')
            ->addFieldToFilter('purchased_id', array('in' => $purchasedIds))
            ->addFieldToFilter('status',
                array(
                    'nin' => array(
                        Mage_Downloadable_Model_Link_Purchased_Item::LINK_STATUS_PENDING_PAYMENT,
                        Mage_Downloadable_Model_Link_Purchased_Item::LINK_STATUS_PAYMENT_REVIEW
                    )
                )
            );

但是，这不会返回产品名称或sku。所以我正在尝试将集合连接到catalog_product_flat表。

$productTableName = Mage::getSingleton('core/resource')->getTableName('catalog/product_flat');
$purchasedItems->getSelect()
            ->join(array('products' => $productTableName), 'main_table.product_id = products.entity_id', array('table_alias.*'));

执行var_dump($purchasedItems)会返回Mage_Downloadable_Model_Resource_Link_Purchased_Item_Collection Object。但我无法迭代$purchasedItems。

非常感谢任何帮助。

请查看加入magento定制，我在我的项目中使用它并且它工作正常。

语法

$collection = Mage::getModel('module/model_name')->getCollection();

$collection->getSelect()->join(Mage::getConfig()->getTablePrefix().'table_name_for_join', 'main_table.your_table_field ='.Mage::getConfig()->getTablePrefix().'table_name_for_join.join_table_field',array('field_name_you_want_to_fetch_from_db'));

工作查询示例

$collection = Mage::getModel('module/model_name')->getCollection();
$collection->getSelect()->join(Mage::getConfig()->getTablePrefix().'catalog_product_entity_varchar', 'main_table.products_id ='.Mage::getConfig()->getTablePrefix().'catalog_product_entity_varchar.entity_id',array('value'));

希望这对你也有用！

干杯！
