Use below code in view file form variable :

<?php $form = ActiveForm::begin([
                'id' => 'login-form', //your form id
                'enableAjaxValidation' => true,
                'enableClientValidation' => false,
                'validateOnBlur' => false,
                'validateOnType' => false,
                'validateOnChange' => false,
            ]) ?> 

Use below code in your controllers action :

public function actionCreate()
{
    $model = new Developers();
    if(Yii::$app->request->isAjax && $model->load(Yii::$app->request->post()) )
    {
      if($model->validate())
      {
        // do here anything 
        $model->save();
      }
      else
      {
        Yii::$app->response->format = 'json';
        return ActiveForm::validate($model);
      }
    }
    else
    {
     return $this->render('_form', [
        'model' => $model
     ]);
    }
}
