Please, check the $form->render('field')

@Studentsov Could you please take a look?

Phalcon 3.4.0

If you set the form itself as it's entity, calling clear() method won't have any effect as the form will still be populated with $_POST values. Is this intended behavior or bug?

$form->setEntity($form);

if ($form->isValid($_POST)) {
    echo $form->getValue('password'); // secret
    echo $form->get('password')->getValue(); // secret
    $form->clear();
    echo $form->getValue('password'); // secret
    echo $form->get('password')->getValue(); // secret
}
