对于我的类别视图。我有一个选择下拉列表,它使用ajax设置带有选项值的会话。
我已覆盖Mage_Catalog_Block_Product_List
。
从ajax处理的会话值在' protected function _getProductCollection()
'覆盖以根据需要过滤产品集合。
我的第一个问题是我想基于这些属性的三个值来过滤属性:
$collection = parent::_getProductCollection();
$collection ->addAttributeToFilter('name', array('in' => array('Cat','Adam', 'Paul')));
$collection->addAttributeToSort('name = Cat', 'DESC');
$collection->addAttributeToSort('name = Adam', 'DESC');
$collection->addAttributeToSort('name = Paul', 'DESC');
return $this->_productCollection;
问题是我想根据需要定位这些。例如,我首先需要Cat然后是Adam然后是Paul。有没有办法定位这些?
第二个问题是我需要定位' sort by
'选项。 ' asc
'是默认值,但是我需要将它降为默认值。
到目前为止,我已覆盖'Mage_Catalog_Block_Product_List_Toolbar'
并使用此代码:
protected $_direction = 'desc';
但这并没有改变方向。
排序是否优先于我创建的自定义产品系列?

答案 0 :(得分:0)
尝试使用finset:
$collection->addAttributeToFilter('name', array('finset'=>array('Cat','Adam','Paul')));
finset使用MySQL的FIND_IN_SET函数
