php - Laravel:如何根据用户权限返回验证消息？

Question

我有用于检查用户权限的示例函数:is_admin()、is_university() 和 is_student()。函数的返回值是 bool 值。我有简单的验证方法:

protected function validator(array $data)
{        
    return Validator::make($data, [

        "$this->recipient" => [
            'sometimes',
            'required',
            'email',
            'exists:users,email',
            Rule::notIn([auth()->user()->email])
        ],

        "$this->subject" => 'sometimes|required|min:10',

        "$this->message" => 'sometimes|required|min:50',

    ], $this->validator_messages());
}

现在我无法通过在此处检查用户权限来发送消息:

public function send(Request $request)
{
    $recipient = $request->recipient;

    if(User::is_student() == true AND User::is_student($recipient) == true OR User::is_student() == true AND User::is_admin($recipient) == true){
        return false; // Or here I can redirect to back.
    }

    $this->validator($request->all())->validate();
    $this->create($request->all());
    return redirect($this->redirectToAfterSendMessage);
}

在我的代码中，如果发件人是学生，则学生无法向学生和管理员发送消息。如何通过检查发件人和收件人的权限来返回验证消息？谢谢大家的回答!

你说过你想重定向回来。所以，而不是:

return false;

重定向用户:

return back()->with('error', 'Your error message');
