用户共同朋友船检查laravel

Question

我在laravel v4.2项目中工作，现在我不明白我如何重新解决这个问题。 我有一个用户数组和登录用户ID现在我想要检查登录用户是否跟随数组中的任何用户，要么是任何单个数组用户跟随登录用户。然后其中一个跟随并且两个数组彼此跟随然后它返回true。但我希望通过laravel relashionship这个问题。 下面是我编码的代码

$login_id = 2;

$users_arr = Array
(
    [0] => 87
    [1] => 9595
    [2] => 8625
    [3] => 18368
    [4] => 18363
    [5] => 18371
)

    class User extends Eloquent  {

            protected $table = 'users';
            protected $primaryKey = 'id';
            protected $guarded = array();
            protected $hidden = array();

        public function mutual_friends() {
           return $this->belongsToMany('User', 'friends', 'follower_id', 'following_id');
        }


        public static function get_users_infomation_by_ids($login_id, $users_arr = array()) {
            $users = User::where(function($sql) use($login_id, $users_arr) {
                        $sql->whereIn('id', $users_arr);
                    })->with(['mutual_friends'=>function($sql) use($login_id){
                        $sql->where('follower_id','=',$login_id);
                        $sql->orWhere('following_id','=',$login_id);
                    }])->get(array('id', 'username', 'full_name', 'is_live', 'message_privacy', 'picture'));
            return (!empty($users) && count($users) > 0) ? $users->toArray() : array();
        }
   }

朋友表包含列{id,follower_id,following_id}

后的列表

现在我希望任何一个条件都为真，然后函数返回true并显示用户信息。

输出

                                )
                        )
                )
        )
)

在上面的outpu id-＆gt; 18363没有相互记录，这只是因为这个 用户即使是跟随此用户的登录用户也不会关注登录用户。

Answer 1

$users = User::whereIn('id', $users_arr)
       ->with('mutual_friends')
       ->where(function ($query)  use ($login_id){
            $query->whereRaw('users.id=friends.follower_id OR users.id=friends.following_id')->where(function($q) use ($login_id){
              $q->where('follower_id',$login_id);
           });
        })
       ->get(array('id', 'username', 'full_name', 'is_live', 'message_privacy', 'picture'));
