ECSHOP 商品分类树显示商品总数的方法

效果如图：

1、includes/lib_goods.php 下
找到这两个函数改成我这样就行
function
get_categories_tree($cat_id = 0)
function get_child_tree($tree_id = 0)

/**
* 获得指定分类同级的所有分类以及该分类下的子分类
*
* @access  public
* @param   integer     $cat_id     分类编号
* @return  array
*/

{
    if ($cat_id > 0)

    }
    else
    {
        $parent_id = 0;
    }

     判断当前分类中全是是否是底级分类，
     如果是取出底级分类上级分类，

在模板文件中，可能是category_tree.lbi中，也可能是别的库文件名，总之看模板去改

在{$cat.name}后添加：({$cat.goods_num})

在{$child.name}后添加：({$child.goods_num})

在{$childer.name}后添加：({$childer.goods_num})
