foreach Laravel上的多id-PHP问题
我有一个搜索功能，我需要添加帖子的foreach Laravel上的多id-PHP问题,php,database,laravel,Php,Database,Laravel,我有一个搜索功能，我需要添加帖子的id（从表观点，列id）。在我看来，我已经有了主题，我从数据库中通过$user->subject获得它，但在$user->id中，我得到的是用户的id，而不是帖子的id。因此，我需要正确地获取数据。我需要得到基于主题的帖子id 现在，我创建了一个新变量，它返回如下内容： $user = Opinion::where ( 'subject', 'LIKE', '%' . $q . '%' ) ->join('role
id观点id主题$user->subject$user->id$user = Opinion::where ( 'subject', 'LIKE', '%' . $q . '%' )
->join('role_users' , 'role_users.user_id', '=', 'opinions.user_id')
->join('roles' , 'roles.id', '=', 'role_users.role_id')
->join('users', 'users.id', '=', 'opinions.user_id')
->orWhere ( 'opinions.user_id', 'LIKE', '%' . $q . '%' )
->orWhere ( 'opinions.id', '=', 'opinions.subject')
->orWhere('opinions.category_id' ,'=', $category->id)
->orWhere ( 'opinions.user_id', '=', 'users.username')
->get ();
$topic_id = Opinion::select('id', 'subject')

您可以在查询生成器中添加select函数来获取意见id，如下所示
$user = Opinion::where ( 'subject', 'LIKE', '%' . $q . '%' )
->join('role_users' , 'role_users.user_id', '=', 'opinions.user_id')
->join('roles' , 'roles.id', '=', 'role_users.role_id')
->join('users', 'users.id', '=', 'opinions.user_id')
->orWhere ( 'opinions.user_id', 'LIKE', '%' . $q . '%' )
->orWhere ( 'opinions.id', '=', 'opinions.subject')
->orWhere('opinions.category_id' ,'=', $category->id)
->orWhere ( 'opinions.user_id', '=', 'users.username')
->select('opinions.id as id','subject')
->get ();
您已经使用“$OPTIONE->id”获得了OPTIONS表id列，不确定您到底需要什么…使用{{{{$OPTIONE->id}
我得到了未定义的变量。也许问题就在这里->join（'users'、'users.id'、'='、'opinions.user_id'）
因为，从我添加这个时起，post中的id就变成了用户的id。您能否显示使用dd（$user）的输出
pleaseSure，通过Bassem Samir的查询，我获得了正确的帖子id，但现在我需要根据用户id
从表用户
从表意见
中获得用户名
（id和主题也在哪里）。这里是dd（$user）
：嗯，现在我得到了正确的id，但是现在我没有用户id:）我怎么能把它带回来？现在我需要根据表用户id
中的用户id
从表用户中获取用户名
。
将它们添加到上面的选择函数中```->选择（'opinions.id作为id'，'subject'，'users.id作为用户id'，'username'））``opinions.user\u id as users.username？以相同的方式将其添加到选择函数'role\u users.role\u id as role\u id'
