How to search for 2 fields at once in Exist Validator?

Question

Yii

Hi friends!
There is a need to check the existence of a record in the database during validation, but only look for not one field in the table, but two. Can this be done using the standard exist-validator methods?
Now it looks like this:

['zip', 'exist', 'targetClass' => ZipKz::className(), 'targetAttribute' => 'zip_new', 'when' => function($model){
  return $model->geo == 'KZ';
}],

Those. the zip field is checked in the index table, and in this table there are 2 columns (zip_new, zip_old), and you need to look for a match on both.

['zip', 'exists', 'targetClass' => ZipKz::className(), 'targetAttribute' => ['zip_old', 'zip_new'], 'when' => function($model){
  return $model->geo == 'KZ';
}],
