ecshop 首页 商品属性 筛选 如何实现

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

            " WHERE cat_id = '$cat_id'");
    }

调用的时候

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