Yii2 Simple Ad Hoc Validation

Question

I create a simple validation like :

public function actionMerchant() {

    $post = Yii::$app->request->post();

    $model = DynamicModel::validateData($post, [
        [['mid'], 'required'],
        [['mid'], 'integer'],
        ['email', 'email'],
    ]);

    if ($model->hasErrors()) {
        return [
            "message" => "Validation fail. Please check your input!"
        ];
    }

    return $model;
}

From the above code, I expect if I send the post parameters for both mid and email parameters, both parameters can be validated by the DynamicModel class.

The problem I get, what if I only send email parameters without mid parameters?

I will get Getting unknown property: yii\\base\\DynamicModel::mid error message.

Does the require validation not work?

Thanks

Require validation works fine. Problem is in your DynamicModel, because Yii2 is creating it object attributes from first parameter you pass (for your example thats your $_POST attributes). To make it work correctly, first define model attributes, then load values to it, and then validate.

=== EDIT ===

$model = new DynamicModel(['mid' => null, 'email' => null]);
$model->addRule('email', 'email');
//here add more rules
$model->load($post);
$model->validate();
