  • 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)
        {
            $sql = 'SELECT parent_id FROM ' . $GLOBALS['ecs']->table('category') . " WHERE cat_id = '$cat_id'";
            $parent_id = $GLOBALS['db']->getOne($sql);
        }
        else
        {
            $parent_id = 0;
        }
    
        /*

                }
            }
        }
        return $three_arr;
    }

    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})
