        }
    }
}

Rule Inheritance ¶

Rule class:

class MyRulesValidator extends RulesValidator
{

    protected function rules(): array
    {
        return [
            ['trim'],
            ['string', 'max' => 191],
            ['validateCountry'],
        ];
    }

    public function validateCountry($model, $attribute, $params, $validator)
    {
        if (!in_array($model->$attribute, ['Russia', 'USA'])) {
            $model->addError($attribute, 'The country must be either "Russia" or "USA".');
        }
    }
}

Model:

class MyModel extends Model
{

    public $country;

    public function rules()
    {
        return [
            ['country', MyRulesValidator::class],
        ];
    }
}
