我们有一个分层导航(screenshot),允许我们的用户按类别,价格和颜色进行过滤。类别和价格工作得很好,因为它们默认为Magento。尝试按颜色(自定义属性)进行过滤时出现问题。
它会引发异常。我能够追踪堆栈跟踪,但我无法理解它。想知道是否有人可以帮我指出正确的方向。跟踪:https://gist.github.com/4490917
我们正在使用Magento Enterprise v1.12.0.2

存在问题使用以下内容换掉你的课程,这个问题应该解决了。
class Mage_Catalog_Model_Resource_Layer_Filter_Attribute extends Mage_Core_Model_Resource_Db_Abstract
{
/**
* Initialize connection and define main table name
*
*/
protected function _construct()
{
$this->_init('catalog/product_index_eav', 'entity_id');

* @param int $value
* @return Mage_Catalog_Model_Resource_Layer_Filter_Attribute
*/
public function applyFilterToCollection($filter, $value)
{
$filterSingleton = FilterSingleton::singleton();
if (!isset($filterSingleton->return)) {
$collection = $filter->getLayer()->getProductCollection();
$attribute = $filter->getAttributeModel();
$connection = $this->_getReadAdapter();
$tableAlias = $attribute->getAttributeCode() . '_idx';
$conditions = array(

您只需从布局中删除enterprisesearch块,例如下面的catalogsearch.xml:
<catalogsearch_result_index translate="label">
...
<reference name="left">
<remove name="enterprisesearch.leftnav"/>
</reference>
<reference name="right">
<block type="catalogsearch/layer" name="catalogsearch.rightnav" before="-" template="catalog/layer/view.phtml"/>
</reference>
...
</catalogsearch_result_index>
发生错误是因为它们是两个块在布局中做同样的事情。默认情况下是企业搜索。
