我正在使用以下教程按选项(过滤)显示最畅销的产品,以显示在 magento 的产品列表页面上?
/app/code/local/Mage/Catalog/Model/Resource/Product/collection.php
<?php
public function sortByReview($dir){
$table = $this->getTable('review/review');
$entity_code_id = Mage::getModel('review/review')->getEntityIdByCode(Mage_Rating_Model_Rating::ENTITY_PRODUCT_CODE);
$cond = $this->getConnection()->quoteInto('t2.entity_pk_value = e.entity_id and ','').$this->getConnection()->quoteInto('t2.entity_id = ? ',$entity_code_id);
$this->getSelect()->joinLeft(array('t2'=>$table), $cond,array('review' => new Zend_Db_Expr('count(review_id)')))
->group('e.entity_id')->order("review $dir");
}
?>
但我想对每个类别中最畅销的产品进行排序。
我怎样才能做到这一点?有没有可用的免费扩展?
