[fw-general] Zend_Form Form and Action on different function

[Bagus Nugroho]

Hi,
 
How to make validation if form and action on different function, 
==============================================
class FooController extends Zend_Controller_Action{
public function barAction(){
 /**
  function will be defined here
  but action wil be on processAction()
 */
  $form = new My_Form();
  $form->setAction('process');
 
  /** on same function
   if($form->isValid($_POST)){
  */
}
 
public function processAction(){
   /**
    check if the data is valid
   */
   if($????->isValid($_POST)){
      echo 'data inserted';
    }
   }
}
=======================================
 
How we can get form that have been submitted?
 
Thanks in advance
