Class Phalcon\Validation\Validator\Uniqueness¶extends abstract class Phalcon\Validation\CombinedFieldsValidator implements Phalcon\Validation\ValidatorInterface Check that a field is unique in the related table <?php
use Phalcon\Validation\Validator\Uniqueness as UniquenessValidator;
$validator->add('username', new UniquenessValidator([
'model' => new Users(),
'message' => ':field must be unique'
]));
Different attribute from the field:
<?php
$validator->add('username', new UniquenessValidator([
'model' => new Users(),
'attribute' => 'nick'
]));
In model:
<?php
$validator->add('username', new UniquenessValidator());
Combination of fields in model:
<?php
$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:
<?php
$validator->add('username', new UniquenessValidator([
'convert' => function (array $values) {
$values['username'] = strtolower($values['username']);
return $values;
}
]));
