I'd rather override Zend_Form::isValid() in that case where for example, based
on a checkbox a set of form elements becomes required:
class MyForm extends Zend_Form
{
public function isValid($data)
{
if (isset($data['shipping']) && (bool) $data['shipping'] === true) {
$this->getElement('shipping-address')->setRequired();
}
return parent::isValid($data);
}
}
Then you keep you logic within the validation steps and not affecting the form
instantiation.
