Toastr通知失败表单提交

Question

我在我的应用程序中使用toastr通知。当表单提交由于验证失败或表单提交成功时，我会发送通知。我通常做这种方式：

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); 
    } 

但是当表中的列数大（10列或更多），我想使用表单请求类代替，而不是在店里方法声明的规则。因此，它成了这个样子：

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); 
    } 

的问题是，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？这一切，并感谢！

Adding After Hooks To Form Requests正是你需要在你的请求类的内容：

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 
     } 
    }); 
}
