【中文标题】如何从 Magento 搜索中过滤掉某些类别的产品？

【英文标题】：How do I filter out products from certain categories from Magento search?

【发布时间】：2013-09-04 06:41:23

【问题描述】：

我尝试在 Mage/Catalog/Block/Product/List.php 上添加以下内容，_getProductCollection()

 $this->_productCollection
->addAttributeToFilter('category_id', array('nin' => array('36,37'),));

但它想出了：

Fatal error: Call to a member function getBackend() on a non-object in C:\app\code\core\Mage\Eav\Model\Entity\Abstract.php on line 816

我怀疑是因为它正在寻找产品没有“category_id”的属性，我尝试添加：

 $this->_productCollection
->joinField('category_id', 'catalog/category_product', 'category_id', 'product_id = entity_id', null, 'left')
    ->addAttributeToFilter('category_id', array('nin' => array('36,37'),));

但这带来了另一个错误：

Joined field with this alias is already declared"

我做错了什么？ Mage/Catalog/Block/Product/List.php 是应用此覆盖的正确文件吗？ 我只是希望它适用于搜索结果，即catalogsearch/result/

【参考方案1】：

尝试使用 ** ->addCategoriesFilter($category);** 而不是 ->addAttributeToFilter(

它对我有用:)

【讨论】：

我试过了，但是 ->addCategoriesFilter($category) 只过滤一个类别，它添加一个类别，而不是删除。我需要删除几个类别。

【参考方案2】：

其实这里需要一点小改动

->addAttributeToFilter('category_ids',array('nin'=>'36'))

category_ids 而不是 category_id ;)

【讨论】：

Hi Sandeep 此更改带来了 SQL 错误：“where 子句”中的未知列“e.category_ids”

使用->printLogQuery(true) 把sql粘贴到这里让我检查

评论太大了。请看下面

【参考方案3】：

这是我使用 addAttributeToFilter('category_ids') 时导致错误的 SQL

选择e.*, search_result.relevance, price_index.price, price_index.tax_class_id, price_index.final_price, IF(price_index.tier_price IS NOT NULL , LEAST(price_index.min_price, price_index.tier_price), price_index.min_price) AS minimal_price, price_index.min_price, price_index.max_price, price_index.tier_price, @9876543337. 987654338@ AS cat_index_position FROM catalog_product_entity AS e INNER JOIN catalogsearch_result AS search_result ON search_result.product_id=e.entity_id AND search_result.query_id='2677' INNER JOIN catalog_product_index_price AS price_index on price_index.entity_id = e.entity_id AND price_index.website_id = '1' AND price_index.customer_group_id = 0 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(3, 4) AND cat_index.category_id='2' WHERE (e.@ 987654349@ NOT IN('36,37')) AND (e.category_ids NOT IN('36,37')) ORDER BY relevance desc LIMIT 20

【参考方案4】：

嗯，我得到了它的工作。试试这个：

/*my rand products here*/
$products->getSelect()->order(new Zend_Db_Expr('RAND()'));
$products->setPageSize(4)->setCurPage(1);
$this->setProductCollection($products);

/*this made the trick*/
$array_ids_cat=array();
foreach($category_ids as $cat_id)
    $array_ids_cat[]=array('finset'=>$cat_id);


$_products = $this->getProductCollection()->joinField('category_id', 'catalog/category_product', 'category_id', 'product_id = entity_id', null, 'left')                                            ->addAttributeToFilter('category_id', $array_ids_cat  );
