通过学习、查询，解决该问题。

方案如下：

修改 includes/lib_insert.php 文件，

增加一个函数

代码如下:

/**

* 调用某商品的累积售出

*/

function insert_goods_sells($arr)

{

$sql = 'select sum(goods_number) as number ' .

' from ' . $globals['ecs']->table('order_goods') . as og , . $globals['ecs']->table('order_info') . as o .

where og.order_id = o.order_id and og.goods_id=.$arr['goods_id'];

$row = $globals['db']->getrow($sql);

if ($row)

{

$number = intval($row['number']);

}

else

{

$number = 0;

}

return $number;

}

修改模板下goods.dwt文件

增加一行代码

<strong>累计售出：</strong>{insert name='goods_sells' goods_id=$id}{$goods.measure_unit}
