Magento:缺货中显示产品类别页最后的产品

问题描述:

我正在使用Magento 1.7.0.2,并且我在/ app/code/core/Mage/Catalog/Block/Product/list中使用了此代码行。 php:Magento:缺货中显示产品类别页最后的产品

$this->_productCollection = $layer->getProductCollection() 
        ->joinField(
         'inventory_in_stock', 
         'cataloginventory_stock_item', 
         'is_in_stock', 
         'product_id=entity_id', 
         'is_in_stock>=0', 
         'left') 
        ->setOrder('inventory_in_stock','desc'); 

当排序的位置和名称缺货产品是最后一次。但是,当按价格排序时,缺货产品的排列顺序并不是最后的。

我该如何使缺货产品即使在价格之后也能持续使用?

我找到了答案

您必须添加以下代码:

$this->getSelect()->joinLeft(
      array('_inventory_table'=>$this->getTable('cataloginventory/stock_item')), 
      "_inventory_table.product_id = e.entity_id", 
      array('is_in_stock', 'manage_stock') 
     ); 
     $this->addExpressionAttributeToSelect('on_top', 
     '(CASE WHEN (((_inventory_table.use_config_manage_stock = 1) AND (_inventory_table.is_in_stock = 1)) OR ((_inventory_table.use_config_manage_stock = 0) AND (1 - _inventory_table.manage_stock + _inventory_table.is_in_stock >= 1))) THEN 1 ELSE 0 END)', 
     array()); 
     $this->getSelect()->order('on_top DESC'); 

就在

if ($attribute == 'price' && $storeId != 0) { 
在应用

/码/ COR如果你有Magento 1.7,或者在app/code/core/Mage/Catalog/Model/Resource/Product/Collection.php中。 0.0 +

我推荐你跑两个系列 1.收藏的产品有现货按价格排序。 - > addAttributeToFilter('is_in_stock',array('gt'=> 0)); 参考链接集合: http://www.magentocommerce.com/knowledge-base/entry/magento-for-dev-part-8-varien-data-collections

  1. 收集的是由价格outofstock排序产品。
  2. 请参考以下链接: Magento List all out of stock items

如果你能告诉我究竟该怎么做或给我的代码将是完美的:) – Alex 2013-04-08 19:37:53

很好找Alex!小贴士:如果你想避免更改核心文件(也可能使之成为一个模块这一点),你可以将其添加到事件侦听器,像这样(在1.8.1.0测试):

/** 
* Fires before a product collection is loaded 
* 
* @param Varien_Event_Observer $observer 
*/ 
public function catalog_product_collection_load_before($observer) 
{ 
    $collection = $observer->getCollection(); 
    $collection->getSelect()->joinLeft(
     array('_inventory_table'=>$collection->getTable('cataloginventory/stock_item')), 
     "_inventory_table.product_id = e.entity_id", 
     array('is_in_stock', 'manage_stock') 
    ); 
    $collection->addExpressionAttributeToSelect(
     'on_top', 
     '(CASE WHEN (((_inventory_table.use_config_manage_stock = 1) AND (_inventory_table.is_in_stock = 1)) OR ((_inventory_table.use_config_manage_stock = 0) AND (1 - _inventory_table.manage_stock + _inventory_table.is_in_stock >= 1))) THEN 1 ELSE 0 END)', 
     array() 
    ); 
    $collection->getSelect()->order('on_top DESC'); 
    // Make sure on_top is the first order directive 
    $order = $collection->getSelect()->getPart('order'); 
    array_unshift($order, array_pop($order)); 
    $collection->getSelect()->setPart('order', $order); 
} 

编辑:改变返回catalog_product_collection_load_before from catalog_product_collection_apply_limitations_before和固定订单部分优先级。
