    {
        return [

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

            ]);
        }

Answer 1

I guess the parameter named mobile_number does not exist in your data or it is an empty string, so try to add 'skipOnEmpty' => false in your code.

Anyway, it works for me.

public function rules()
{
    return [
        ['mobile_number', 'required', 'skipOnEmpty' => false],
        ['mobile_number', 'myfunction', 'skipOnEmpty' => false],
    ];
}

Answer 2

are you sure you are not extending the model class ? if so you need to put this :

$model->validate()

Answer 3

Your Model:

public function rules()
{
    return [
        ['mobile_number', 'required'],
        ['mobile_number', 'myfunction'],
    ];
}

public function myfunction($attribute,$params)
{
    $this->addError($attribute, 'You have already submitted');
    return false;   
}

And your controller:

public function actionCreate()
{
    $model = new Createuser();

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

Answer 4

try this in your controller

protected function performAjaxValidation($model = NULL) {

        if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
            Yii::$app->response->format = Response::FORMAT_JSON;
            echo json_encode(ActiveForm::validate($model));
            Yii::$app->end();
        }
    }

public function actionCreate()
{
    $model = new Createuser();
    $this->performAjaxValidation($model);
    if ($model->load(Yii::$app->request->post()) && $model->save() && $model->validate()) {
        return $this->redirect(['view', 'id' => $model->id]);
    } else {
        return $this->render('create', [
            'model' => $model,
        ]);
    }
}
