请教各位大神, ecshop商品属性多条件筛选, 只能在商品分类列表页才能实现, 请问如何才能在全站都能实现这个功能呢?
类似京东的全部商品分类, 急求, 试了很多方法都不能成功调用...
该问题已经解决, 贴出来给大家分享一下, 如果不正确的地方, 希望指出, 谢谢
把下面这段代码 Copy到程序根目录 index.php里面
/**
* 获得分类的信息
*
* @param integer $cat_id

* @return void
*/

" WHERE cat_id = '$cat_id'");
}
/**
* 获取商品类型属性
* @param $cat_id 栏目ID
* @return array 商品属性
*/
function get_my_class($cat_id)
{
$children = get_children($cat_id);
$cat = get_cat_info($cat_id); // 获得分类的相关信息
/* 属性筛选 */
$ext = ''; //商品查询条件扩展
if ($cat['filter_attr'] > 0)
{
$cat_filter_attr = explode(',', $cat['filter_attr']); //提取出此分类的筛选属性
$all_attr_list = array();

{

调用的时候
$all_attr_list = get_my_class(22);
$smarty->assign('woshi', $all_attr_list);
