方案如下：

修改includes/lib_insert.php文件，

增加一個函數

/**

*調用某商品的累積售出

*/

functioninsert_goods_sells($arr)

{

$sql='SELECTSUM(goods_number)ASnumber'.

'FROM'.$GLOBALS['ecs']->table('order_goods')."ASog,".$GLOBALS['ecs']->table('order_info')."ASo".

"WHEREog.order_id=o.order_idandog.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

增加一行代碼

<strong>累計售出：</strong>{insertname='goods_sells'goods_id=$id}{$goods.measure_unit}
