            [
                'message' => 'The captcha is not valid',

The IpValidator validates a valid ip address.

$data['ip'] = $this->request->getPost('ip');

$validation = new \Phalcon\Validation();

$validation->add(
    'ip',

            'message' => 'The IP is not valid.', // Optional
        ]

}

// Validation succeeded without errors

$data['number'] = $this->request->getPost('number');

$validation = new \Phalcon\Validation();

$validation->add(
    'number',
    new \MicheleAngioni\PhalconValidators\NumericValidator(
