thinkPhp 如何根据子表条件查父表数据
thinkphp 关联查询
旅游线路1:团1:价格1(id,price```)价格2(id,price```)
团2:价格1(id,price```)
价格2(id,price```)
我需要根据价格里的price字段,来筛选团,关系模型已经配了,请问如何封装where条件
回复讨论(解决方案)
建议去看下thinkphp的文档。
thinkphp 文档写的太少 只有一对一关联查询 而且没有涉及到根据关联表的条件查询 而我们开发中往往需要根据关联标的条件来查询 一直不知道这个where因该怎么封装
我想查小于5天的团 而天数line里的days字段
$where["line.days"] = array("elt","5"); 这样不对
我现在是这样解决的
$team = M("Team");
$where = "lineId in (select l.id from line l where l.days $list = $team->where($where)->select();
我感觉现在这样条件一多了 就非常麻烦了 应该有更好地解决办法吧 求大神指点
如果父表和子表关联,可以通过写sql直接连表。
给出表结构看看

恩 sql可以解决 但是想知道有没有thinkphp里有没有跟简单的方法 能不能像hibernate那样 直接把关系表的字段当做自己的属性

那你直接通过thinkphp的 orm写sql吧。

你直接在controller写操作的sql
恩 看来除了写sql,还真没有更好的方法。谢谢各位提供的建议。
