Question about using a mask?

Question

Yii

what is the essence of the mask form the phone

<?= $form->field($model, 'phone')->widget(\yii\widgets\MaskedInput::className(), [
            'mask' => '[phone]',
            'clearIncomplete'=>true
    ]) ?>

but I need to send it to me exactly as a number without all this tinsel + () - the question is how this can be organized, given the validation.
And in order not to get up twice, how can you then display these phones with a mask to clients? The mask is created purely for the convenience of clients, not for storage in the database.

Answer 1

write logic in beforeSave and afterFind. Accordingly, clean from brackets, the "+" sign and spaces before saving and add after the selection.
