Question

在Magento中，我使用以下代码来获取畅销书数据集：

模型功能：

  public function bestSellers($limit = 12){

    $storeId    = Mage::app()->getStore()->getId();
    $_productCollection = Mage::getResourceModel('reports/product_collection')
        ->addOrderedQty()
        ->addAttributeToSelect('id')
        ->setStoreId($storeId)
        ->addStoreFilter($storeId)
        ->setOrder('ordered_qty', 'desc') //best sellers on top
        ->setPageSize($limit); 

    Mage::getSingleton('catalog/product_status')->addVisibleFilterToCollection($_productCollection);
    Mage::getSingleton('catalog/product_visibility')->addVisibleInCatalogFilterToCollection($_productCollection);

    return $_productCollection; 

}

阻止输出：

<?php $products = Mage::getModel('tabs/collections')->bestSellers($limit); ?>
<pre>
    <?php print_r($productCollection->getData()); ?>
</pre>

但是当在模型函数中使用addVisibleInCatalogFilterToCollection行时，它什么都不返回，但是如果我删除了addVisibleInCatalogFilterToCollection行，那么它返回一个预期的畅销产品数据的数组（包括那些在目录中不可见的数据）

如何使用可见性过滤器工作原样返回我的数据数组？而不是一无所获。非常困惑。提前谢谢！

这是getSelect：

   SELECT SUM(order_items.qty_ordered) AS `ordered_qty`, `order_items`.`name` AS `order_items_name`, `order_items`.`product_id` AS `entity_id`, `e`.`entity_type_id`, `e`.`attribute_set_id`, `e`.`type_id`, `e`.`sku`, `e`.`has_options`, `e`.`required_options`, `e`.`created_at`, `e`.`updated_at`, `cat_index`.`position` AS `cat_index_position` FROM `sales_flat_order_item` AS `order_items`
  INNER JOIN `sales_flat_order` AS `order` ON `order`.entity_id = order_items.order_id AND `order`.state <> 'canceled'
  LEFT JOIN `catalog_product_entity` AS `e` ON (e.type_id NOT IN ('grouped', 'configurable', 'bundle')) AND e.entity_id = order_items.product_id AND e.entity_type_id = 4
  INNER JOIN `catalog_category_product_index` AS `cat_index` ON cat_index.product_id=e.entity_id AND cat_index.store_id='1' AND cat_index.visibility IN(2, 4) AND cat_index.category_id='2' WHERE (parent_item_id IS NULL) GROUP BY `order_items`.`product_id` HAVING (SUM(order_items.qty_ordered) > 0) ORDER BY `ordered_qty` desc

我认为这是因为addVisibleInCatalogFilterToCollection()比你想象的更多。我们来看看它的代码(app\code\core\Mage\Catalog\Model\Product\Visibility.php, line 66)：

public function addVisibleInCatalogFilterToCollection(Mage_Eav_Model_Entity_Collection_Abstract $collection)
{
    $collection->setVisibility($this->getVisibleInCatalogIds());

// $ collection-＆gt; addAttributeToFilter（'visibility'，array（'in'=＆gt; $ this-＆gt; getVisibleInCatalogIds（）））; 返回$ this; }

现在，让我们仔细看看$collection->setVisibility($this->getVisibleInCatalogIds())。我们去\app\code\core\Mage\Catalog\Model\Resource\Product\Collection.php：

public function setVisibility($visibility)
{
    $this->_productLimitationFilters['visibility'] = $visibility;
    $this->_applyProductLimitations();

    return $this;
}

/**
 * Apply limitation filters to collection
 * Method allows using one time category product index table (or product website table)
 * for different combinations of store_id/category_id/visibility filter states
 * Method supports multiple changes in one collection object for this parameters
 *
 * @return Mage_Catalog_Model_Resource_Product_Collection
 */
protected function _applyProductLimitations()
{
    $this->_prepareProductLimitationFilters();
    $this->_productLimitationJoinWebsite();
    $this->_productLimitationJoinPrice();
    $filters = $this->_productLimitationFilters;

    if (!isset($filters['category_id']) && !isset($filters['visibility'])) {
        return $this;
    }

    $conditions = array(
        'cat_index.product_id=e.entity_id',
        $this->getConnection()->quoteInto('cat_index.store_id=?', $filters['store_id'])
    );
    if (isset($filters['visibility']) && !isset($filters['store_table'])) {
        $conditions[] = $this->getConnection()
            ->quoteInto('cat_index.visibility IN(?)', $filters['visibility']);
    }
    $conditions[] = $this->getConnection()
        ->quoteInto('cat_index.category_id=?', $filters['category_id']);
    if (isset($filters['category_is_anchor'])) {
        $conditions[] = $this->getConnection()
            ->quoteInto('cat_index.is_parent=?', $filters['category_is_anchor']);
    }

    $joinCond = join(' AND ', $conditions);
    $fromPart = $this->getSelect()->getPart(Zend_Db_Select::FROM);
    if (isset($fromPart['cat_index'])) {
        $fromPart['cat_index']['joinCondition'] = $joinCond;
        $this->getSelect()->setPart(Zend_Db_Select::FROM, $fromPart);
    }
    else {
        $this->getSelect()->join(
            array('cat_index' => $this->getTable('catalog/category_product_index')),
            $joinCond,
            array('cat_index_position' => 'position')
        );
    }

    $this->_productLimitationJoinStore();

    Mage::dispatchEvent('catalog_product_collection_apply_limitations_after', array(
        'collection'    => $this
    ));

    return $this;
}

因此，正如您所看到的，产品应分配到当前网站，并应从当前网站添加到某个类别，以显示在产品集合中。此外，您还可以看到其他一些要求。

这是我用来获得畅销书的Block。它还提供简单的产品，这些产品是父母可配置产品的变体，可配置产品（仅当一个简单产品被分配给最多1个可配置产品时才能正常工作）：http://devblog.fishol.pl/bestselling-products-in-magento/

Answer 3

仅供将来参考。

我遇到了类似的问题。

其中一个小部件没有显示随机产品。

因为

Mage::getSingleton('catalog/product_visibility')->addVisibleInSearchFilterToCollection($collection);

必须为目录设置产品（产品 - ＆gt;可见性 - ＆gt;目录，搜索）。

使用addVisibleInCatalogFilterToCollection的Magento什么时候不返回
