How to dynamically add validation rules in Yii2?

Question

JavaScript

I am using Active Form. Some form fields are taken from the database. Their type, name and validation rules are stored there. The fields are different and have different characteristics. How to set validation rules for these fields? So that the framework understands them, both on the server side and on the client side.
Stayed to use DynamicModel . But the class needs to pass an attribute with the field value. Means approaches only for server validation. What about the client?

Answer 1

With client validation, you need to add js code

in models, you can assign rules for scenarios

Answer 2

use DynamicModel for this

$model = DynamicModel::validateData(compact('name', 'email'), [
        [['name', 'email'], 'string', 'max' => 128],
        ['email', 'email'],
    ]);

here are the docks:

did this as a form generator (questionnaires), while the data about the fields and their settings are stored in the database in json
