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
]);
}
}
