extends abstract class Phalcon\Validation\CombinedFieldsValidator

1 2 3 4 5 6 | $validator->add('username', new UniquenessValidator([ 'model' => new Users(), 'attribute' => 'nick' ]));In model: |
1 2 3 | $validator->add('username', new UniquenessValidator());Combination of fields in model: |
1 2 3 | $validator->add(['firstName', 'lastName'], new UniquenessValidator());It is possible to convert values before validation. This is useful in situations where values need to be converted to do the database lookup: |
1 2 3 4 5 6 7 | $validator->add('username', new UniquenessValidator([ 'convert' => function (array $values) { $values['username'] = strtolower($values['username']); return $values; } ])); |
