Case:
I have form with one field (Company NIP number) which is uniqe in DB. I woudlike to use one form to add and edit actions but in edit action I need to remove my own Uniqueness validator from "NIP" field. How can I do this? Class Phalcon\Forms\Element has only addValidator and getValidators methods.
Ofcourse I can extends \Phalcon\Forms\Element and implement method "removeValidator" ($_validators is protected variable). but also I need to implement render method in each form field class (check, date, email ...)

In the sample below there's one where u can initialize the form with options. you can use to to do some logic checking
public function initialize(Users $user, $options = []) {
$name = new Text('name', array(
'placeholder' => 'Your name',
'using' => array('id', 'name'),
));
$name->setLabel('Name');
if (empty($options['edit'])) { // !in_array('edit') could work depending ...
// don't add validator when you create the form and set a certain option
$name->addValidators(array(
new PresenceOf(array(
'message' => 'Your name is required'
)),
));
}
$this->add($name);
}
