Yii2 Swiftmailer Test Check Smtp Connection

yii2 swiftmailer Check SMTP Connection

I need to check a smtp connection with username and password (without sending an actual email).

After added smtpmail extension file into extension folder, We have to give the set of details like Hostname, Username, Password, Mailer option, Port and SMTPAuth. We must have to configure this details in main.php before send the mail using this extension. I added the code below

Finally i came with this solution

This is Controller....

       
use Swift;
use Swift_Message;
use Swift_Mailer;
use Swift_SmtpTransport;

class AccountController extends Controller {

    public function actionSmtpSetting() {
     $model = new ModelSMTP();

     if ($model->load(Yii::$app->request->post()) && $model->validate()) {           
                $model->save();            
            return $this->redirect(['index']);
        } else {
            return $this->render('smtp-setting', [
                        'model' => $model
            ]);
        }

    }

    public function actionTestsmtpconnection() {

        if (Yii::$app->request->post()) {
            $post = Yii::$app->request->post('DynamicModel');

            $smtp_host_name = $post['smtp_host_name'];
            $smpt_user_name = $post['smpt_user_name'];
            $smtp_password = $post['smtp_password'];
            $smtp_from_email = $post['smtp_from_email'];

            try {
                $transport = Swift_SmtpTransport::newInstance($smtp_host_name, '587', 'tls');
                $transport->setUsername($smpt_user_name);
                $transport->setPassword($smtp_password);
                $mailer = \Swift_Mailer::newInstance($transport);
                $mailer->getTransport()->start();
                return 'ok';
            } catch (Swift_TransportException $e) {
                return $e->getMessage();
            } catch (Exception $e) {
                return $e->getMessage();
            }
        }
        exit;
    }


}


       
 

This is View With Ajax Validation....

       


        $form = ActiveForm::begin(['enableClientValidation' => true, 'enableAjaxValidation' => false,
                    'fieldConfig' => [
                        'template' => "

{label}

{input}{error}
"
                    ],
                    'options' => ['enctype' => 'multipart/form-data',
                        'class' => 'form-horizontal1',
                        'id' => 'smtp-create']]);
        ?>
            
            field($model, 'smtp_host_name')->textInput(['maxlength' => true, 'value' => $smtp_host_name->value, 'readonly' => $flag]) ?> 
            field($model, 'smpt_user_name')->textInput(['maxlength' => true, 'value' => $smpt_user_name->value, 'readonly' => $flag]) ?> 
            field($model, 'smtp_password')->passwordInput(['maxlength' => true, 'value' => $smtp_password->value, 'readonly' => $flag]) ?>
            field($model, 'smtp_from_email')->textInput(['maxlength' => true, 'value' => $smtp_from_email->value, 'readonly' => $flag]) ?>
            
                
         '']); ?>
