How to check if two fields are identical?

Question

Yii

There is a rules() function, the standard for Active Form. There are two fields: password and repeat password . Question: is it possible to check them for compliance through the rules? There is a built-in validator, CompareValidator , which can perform this action, but when using it, a problem arises. here is a piece of my rules:

// ...
['password_repeat', 'compare', 'compareAttribute' => 'password', 'operator' => '=','message' => 'Пароли не совпадают!'],
// ...

Theoretically, it should work, but in fact, for any values ​​​​of the password and password_repeat fields, it gives out "Passwords do not match" ... What could be the problem?
(I don't think it matters, but the View snippet looks like this:)

<?= $form->field($model, 'password')->hint('Не меньше шести символов.')?>
        <?= $form->field($model, 'password_repeat')->hint('Повторите ввод пароля')?>

Answer 1

Compare Validator https://github.com/yiisoft/yii2/blob/master/docs/g...
remove
'operator' => '=' from the
validator parameters First you wrote the assignment operator and equals, the equals operators are == or === . And secondly, this validator has the == operator by default.
