PHP Class Phalcon\Validation\Validator\Db\Uniqueness

Validator for checking uniqueness of field in database


$uniqueness = new Uniqueness(
    [
        'table'   => 'users',
        'column'  => 'login',
        'message' => 'already taken',
        'exclude' => [
            'column' => 'id',
            'value' => 1 // Some ID to exclude
        ],
    ],
    $di->get('db');
);

Exclude option is optional. If second parameter will be null (omitted) than validator will try to get database connection from default DI instance with \Phalcon\Di::getDefault()->get('db');
