方案如下：修改 includes/lib_insert.php 文件，增加一个函数
复制代码代码如下:
/*** 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}有人要进来，有一些人不得不离开。
