在Ecshop后台打印订单页面将商品按货号排序

28891

ECSHOP后台管理里的“打印订单" 页面里的商品排序有点乱，现在想改成按序号来排序，修改方法如下

下面是在2.7.2基础上做的修改

打开 admin/order.php 文件

找到(大约在311行左右)

$sql = "SELECT o.*, IF(o.product_id > 0, p.product_number, g.goods_number) AS storage, o.goods_attr, g.suppliers_id, IFNULL(b.brand_name, '') AS brand_name, p.product_sn
         FROM " . $ecs->table('order_goods') . " AS o
            LEFT JOIN " . $ecs->table('products') . " AS p
                  ON p.product_id = o.product_id
            LEFT JOIN " . $ecs->table('goods') . " AS g
                  ON o.goods_id = g.goods_id
            LEFT JOIN " . $ecs->table('brand') . " AS b
                  ON g.brand_id = b.brand_id
         WHERE o.order_id = '$order[order_id]'";

修改为
