Question

我想在我的Magento 1.9网站上添加一个链接，该链接显示所有类别的所有待售产品。我发现以下文章介绍了如何通过覆盖Mage_Catalog_Block_Product_List来显示当前类别中的待售产品。

http://inchoo.net/magento/more-flexible-approach-for-listing-out-products-on-sale-in-magento/

所以这让我思考。而不是尝试创建一个新页面来显示销售的产品，而是创建一个名为Sale的类别。然后重写Mage_Catalog_Block_Product_List方法并检查当前类别是否为“销售”类别，并将$this->_productCollection设置为包含所有待售产品的集合。

我在试图让它发挥作用时遇到了一些问题。

事实上，我很难获得我的类别中显示的所有产品的集合，因此我可以将其过滤掉，以便它只包含待售的产品。目前，我的代码将$this->_productCollection设置为包含网站上所有产品的集合（包括我的可配置产品的简单产品）。我只想要在我的类别中显示的产品。

有人可以告诉我如何获取我网站上销售的所有产品以及如何设置$this->_productCollection以便显示促销产品吗？

我已粘贴到目前为止我写的代码

这会将On Sale产品的产品系列设置为当前日期：

    $todayDate  = Mage::app()->getLocale()->date()->toString(Varien_Date::DATETIME_INTERNAL_FORMAT);
    $storeId    = Mage::app()->getStore()->getId();
    $products = Mage::getResourceModel('catalog/product_collection')
        ->addAttributeToSelect(Mage::getSingleton('catalog/config')->getProductAttributes())
        ->addMinimalPrice()
        ->addUrlRewrite()
        ->addTaxPercents()          
        ->addStoreFilter()
        ->addAttributeToFilter('special_to_date', array('date'=>true, 'from'=> $todayDate));

    Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($products);
    Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($products);
    $products->setPageSize($this->getConfig('qty'))->setCurPage(1);
    $this->setProductCollection($products);
