Yii2: ajax form validation on an ajax submitted form

Question

I\'m wondering if any Yii2 experts can help me understand how best to work with ajax forms combined with Yii ajax validation. I think I can explain the issue without taking you

Answer 1

I have found solution :

Form :

  'form-add-contact', 'enableAjaxValidation' => true, 'validationUrl' => Yii::$app->urlManager->createUrl('contacts/contacts/contact-validate')]);
    ?>

Submit Via Ajax :

registerJs($script);
?>

Controller :

/*
     * CREATE CONTACT FORM  AJAX VALIDATION ACTION
     */

    public function actionContactValidate() {
        $model = new ContactsManagement();
        if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
            $model->company_id = Yii::$app->user->identity->company_id;
            $model->created_at = time();
            \Yii::$app->response->format = Response::FORMAT_JSON;
            return ActiveForm::validate($model);
        }
    }


/**
     * Quick Add Contact Action
     * @param type $id
     * @return type
     */
    public function actionAddContact() {           

        $model = new ContactsManagement();

        if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {

            $transaction = \Yii::$app->db->beginTransaction();

            try {
                if ($model->validate()) {
                    $flag = $model->save(false);
                    if ($flag == true) {
                        $transaction->commit();

                        return Json::encode(array( 'status' => 'success', 'type' => 'success', 'message' => 'Contact created successfully.'));
                    } else {
                        $transaction->rollBack();
                    }
                } else {
                    return Json::encode(array('status' => 'warning', 'type' => 'warning', 'message' => 'Contact can not created.'));
                }
            } catch (Exception $ex) {
                $transaction->rollBack();
            }
        }

        return $this->renderAjax('_add_form', [
                    'model' => $model,
        ]);
    }
