ecshop 首页 商品属性 筛选 如何实现

Question

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 $cat_id
     *
     * @return  void
     */
    function get_cat_info($cat_id)
    {
        return $GLOBALS['db']->getRow('SELECT cat_name, keywords, cat_desc, style, grade, filter_attr, parent_id FROM ' . $GLOBALS['ecs']->table('category') .
            " WHERE cat_id = '$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();

            foreach ($cat_filter_attr AS $key => $value)

                        if (!empty($filter_attr[$key]) AND $filter_attr[$key] == $v['goods_id'])
                        {
                            $all_attr_list[$key]['attr_list'][$temp_key]['selected'] = 1;

            }

            return $all_attr_list;
        }

调用的时候

$all_attr_list = get_my_class(22);
$smarty->assign('woshi',  $all_attr_list);
