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 $number; }
修改模板下goods.dwt文件
增加一行代码
累计售出:{insert name='goods_sells' goods_id=$id}{$goods.measure_unit}
