Yii2 Kartik Detail View - enableAjaxValidation

Hi all i’m using Kartik Detail View on my standard User model.

My field $user->email in the rules is of "email" type and is "unique" in the database.

I see in Edit-Mode that if i try to insert a wrong-mail i have the right error message.

If i try to insert an existing mail, i don’t have any error, but then when i save i have error on duplicate key.

I know that i must set “enableAjaxValidation” ON, but i don’t try where to set up in the Detail View.

Thank’s for any help.


ok, as usually happend to me, first of all i search over the internet my problem solution or a way that help me.

If i don’t find, i write here.

In the while i’m waiting for any help, i study better each component and i find the solution by myself.

In this case, for future memory i add at the Detail View this configuration:




in the controller i add in the start of the action:

        $check_user = new User();

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

            Yii::$app->response->format = Response::FORMAT_JSON;

            return ActiveForm::validate($check_user);


remember to add these lines in the top of controller:

use yii\web\Response;

use yii\widgets\ActiveForm;

And now my Detail View works fine! :D
