YII2活动表单显示自定义验证消息 [英] YII2 Active Form show custom validation message

问题描述

我有一个登录表单，用于在其中实现集成twilio API的2因子身份验证.

I have login form which, where I am implementing 2 Factor Authentication integrating twilio API.

API运行正常，我可以获取成功或失败的验证响应.

The API is working fine and I can get the verification response for success or failure.

现在，我无法以某种方式显示消息"OTP验证失败".在表格上.

Now I am somehow not able to display the message "OTP verification Failed" on the form.

这是我的控制器代码:

公共功能actionLogin(){

public function actionLogin() {

    $this->layout = '@app/themes/backend/login';
    $model = new LoginForm(['scenario' => 'login']);
        
        if (Yii::$app->request->isAjax && $model->load($_POST)) {
            $authy_id = Yii::$app->session->get('authy_id');
          //  var_dump($authy_id);exit;
          Yii::$app->response->format = 'json';
        //  var_dump($model);exit;
            if(!empty($authy_id)){                
                $authy_api = new AuthyApi('api-key');
                $token_entered_by_user = $model->otp;
               
                $verification = $authy_api->verifyToken($authy_id, $token_entered_by_user);
                

            if ($verification->ok()) {
                // correct token
              //  Yii::$app->response->format = 'json';
                return \yii\bootstrap\ActiveForm::validate($model);
            }else{
               // Yii::$app->response->format = 'json';
                $model->addError('OTP Verification Failed');
              print_r('error');
              Yii::$app->session->setFlash('error', "OTP verification failed!");
              
                exit;

            }

            }else{
            Yii::$app->response->format = 'json';
        return \yii\bootstrap\ActiveForm::validate($model);
            }
    }
    if ($model->load(Yii::$app->request->post()) && $model->login()) {                    
                if (Yii::$app->user->identity->user_role == 'admin') {
    
                    $path = "../" . Yii::$app->user->identity->user_role;    
                    return $this->redirect($path);
                } 
                elseif(Yii::$app->user->identity->user_role == 'customer') {
                    $path = "../" . Yii::$app->user->identity->user_role .'/default/index';
                    return $this->redirect($path);
                }
                
                else{
                    $path = "../" . "site/index";
                     return $this->redirect($path);
        ...
        }
        
        
    }
    return $this->render('login', [
        'model' => $model,
    ]);
}

在我的查看文件中，我尝试过:

and in my view file I have tried like:

<?php pjax::begin(['id'=>'otp-error']); ?>
      <?php  if(Yii::$app->session->hasFlash('error')):?>
        <div class="info" id="otp-error">
       
        <?= Yii::$app->session->getFlash('error') ?>
        
      </div>
      <?php endif?>
      <?php pjax::end(); ?>

我在这里想念什么?

推荐答案

在设置"OTP验证失败！"后删除 exit; .消息.

Remove the exit; after setting the "OTP verification failed!" message.

设置了该即时消息后，您将无所事事.

You are returning to nowhere just after you set that flash message.

请记住，要使Flash消息正常工作，您的代码必须到达您的视图.如果您之前返回或返回JSON，则它将永远不会到达您的客户端.

Remember that for the flash message to work, your code must reach your view. If you return before, or return a JSON, it will never get to your client.
