Question

我已将管理网格添加了类别过滤器，以下是代码

$cat_ids = implode(',', $CatIdArray['CategoryId']);
$collection->getSelect()
         ->join(array('ccp'=>'catalog_category_product'),
            "ccp.product_id = e.entity_id AND ccp.category_id IN({$cat_ids})",
            array('category_id')
         );

现在问题是，当多个类别具有相同的产品时，它会崩溃，以避免这种情况

$collection->groupByAttribute('entity_id');

它返回了我不同的记录，但这打破了paginaion。我知道这是常见的问题，但任何帮助将不胜感激。感谢

如果你面临逐个问题。我使用这种方式多次解决同样的问题。从magento / lib / Varien / Data / Collection / Db.php复制Db.php文件将其粘贴到本地目录，以便生成的文件夹结构如下所示： magento / app / code / local / Varien / Data / Collection / Db.php。现在打开此文件以编辑并用下面的

替换getSelectCountSql函数

public function getSelectCountSql()
    {
        $this->_renderFilters();

        $countSelect = clone $this->getSelect();
        $countSelect->reset(Zend_Db_Select::ORDER);
        $countSelect->reset(Zend_Db_Select::LIMIT_COUNT);
        $countSelect->reset(Zend_Db_Select::LIMIT_OFFSET);
        $countSelect->reset(Zend_Db_Select::COLUMNS);

        if(count($this->getSelect()->getPart(Zend_Db_Select::GROUP)) > 0) {
            $countSelect->reset(Zend_Db_Select::GROUP);
            $countSelect->distinct(true);
            $group = $this->getSelect()->getPart(Zend_Db_Select::GROUP);
            $countSelect->columns("COUNT(DISTINCT ".implode(", ", $group).")");
        } else {
            $countSelect->columns('COUNT(*)');
        }
        return $countSelect;
    }.Try this , hope this will help you.

而不是

$collection->groupByAttribute('entity_id');

使用此

$collection->getSelect()->group('entity_id');

类别过滤器管理具有不同记录的产品网格（使用分组分页）
