Question

我在我的应用中使用toastr通知。当表单提交因验证失败或表单提交成功时，我发送通知。我通常这样做：

public function store(Request $request) {
        $data = $request->all();
        $rules = [
            'name' => 'required|string',
            'email' => 'required|email',
            'message' => 'required|string',
            'g-recaptcha-response' => 'required|captcha',
        ];
        $validate = Validator::make($data, $rules);
        if ($validate->fails()) {
            $error = array(
                'message' => "Error sending the message!",
                'alert-type' => 'error'
            );
            return back()->withErrors($validate)->withInput()->with($error);
        }

        Feedback::create($data);
        $success = array(
            'message' => "Thanks for the feedback! Your message was sent successfully!",
            'alert-type' => 'success'
        );
        return redirect()->route('contactus')->with($success);
    }

但是当表列数很大（10列或更多）时，我想使用表单请求类而不是在store方法中声明规则。所以它变成了这样：

public function store(FeedbackRequest $request) {
        $data = $request->all();

        Feedback::create($data);
        $success = array(
            'message' => "Thanks for the feedback! Your message was sent successfully!",
            'alert-type' => 'success'
        );
        return redirect()->route('contactus')->with($success);
    }

问题是，当使用表单请求时，我不知道如何在验证失败时发送错误通知。有没有办法检查表单请求类验证是否失败，以便我可以发送错误通知？这就是全部，谢谢！

Adding After Hooks To Form Requests正是您在Request类中所需要的：

public function withValidator($validator)
{
    $validator->after(function ($validator) {
        if ($validator->failed()) {
            $validator->errors()->add('field', 'Something is wrong with this field!'); // handle your new error message here
        }
    });
}
