我有以下功能：

使用顶部提到的功能，我想搜索名称和一些学校 ID 作为数组给出的成员。所有这些都在 $searchParams 数组中。但是我找不到使用学校 ID 进行搜索的方法。
$searchParams 的一个示例参数是：
[
'name'=>'Sailor'
'schools'=>[1,2,3]
]
我的数据库中的一些示例数据是
成员：
> id| name | email |
> 1 | Sailor Mooon | sailor@moon.com |
> 2 | Monk1ey D Luffy | monkey.d@luffy.com |
学校
> id | name
> 1 | Kokoro Daigaku
> 2 | Oumi Akademy
> 3 | Univercity of Pokemon Battle
在顶部提到的函数中，我收到以下错误：
: [语义错误] 第 0 行，第 71 列靠近 'id IN ( Select': 错误：AppBundle\Entity\Member 类没有名为 school.id [] [] 的字段或关联
你能帮我解决一下吗？

我设法通过更改来部分解决：
$queryBuilder->andWhere('m.schools IN ( Select s.id FROM AppBundle:Schools s WHERE s.id IN (:schools ) )')->setParameters(['schools'=>$searchParams['schools']]);
进入这个：
$queryBuilder->join('AppBundle:School','s')->andWhere('s.id IN (:schools)')->setParameters(['schools'=>$searchParams['schools']]);
但我得到的成员与任何学校都没有关系。
