ecshop 获取某个商品的 所有订单信息 或者销量

把一下代码放到 lib_main.php

1.统计某个下单商品的人数

function get_goods_ordernum($goods_id){

        $sql = "select count(goods_number) from " . $GLOBALS['ecs']->table('order_goods') . " AS g ,".$GLOBALS['ecs']->table('order_info') . " AS o WHERE o.order_id=g.order_id and g.goods_id = " . $goods_id . " and o.order_status in(1,5) " ;//o.order_status=1 表示确认了的订单才算
return $GLOBALS['db']->getAll($sql); 

}

注意：如果有3个人下单，数量是5 ，那返回结果是3

2.统计某个下单商品的销量，

function get_goods_ordernum($goods_id){

        $sql = "select sum(goods_number) from " . $GLOBALS['ecs']->table('order_goods') . " AS g ,".$GLOBALS['ecs']->table('order_info') . " AS o WHERE o.order_id=g.order_id and g.goods_id = " . $goods_id . " and o.order_status in(1,5) " ;//o.order_status=1 表示确认了的订单才算
return $GLOBALS['db']->getAll($sql); 

}

注意：如果有3个人下单，数量是5 ，那返回结果是5

3.统计某个商品商品订单的详细信息

function get_goods_ordernum($goods_id){

        $sql = "select * from " . $GLOBALS['ecs']->table('order_goods') . " AS g ,".$GLOBALS['ecs']->table('order_info') . " AS o WHERE o.order_id=g.order_id and g.goods_id = " . $goods_id . " and o.order_status in(1,5) " ;//o.order_status=1 表示确认了的订单才算
return $GLOBALS['db']->getAll($sql); 

}

order_status in(1,5)   1表示去人订单，5表示已分单
