How to make a validation for the entered date so that it is no later than the current day?

Question

Yii

The model has an attribute "birthday". How can I use the built-in validator to check that when editing a profile it is impossible to set the date of birth later than the current day?

Answer 1

['birthday', 'date', 'max' => time(), 'tooBig' => 'Дата рождения должна быть не меньше текущей даты'],

Answer 2

Good afternoon.
Try doing this:

['birthday', 'date', 'when' => function($model){
                 return strtotime($model->birthday) < time());
            }, 'message' => 'Дата рождения должна быть не меньше текущей даты'],
