Question

I have an issue with redisplaying a view after a validation failure with a Zend form.

My initial action looks like

public function test1Action() {
    // get a form and pass it to the view
    $this->view->form = $this->getForm(); 

    // extra stuff I need to display 
    $this->view->name = "Bob";
}

and the view

Hello <?= $this->name?>
<?php echo $this->form;?>

The problem comes when the action “test2” called after the form is submitted has a validation error :

public function test2Action() {
    if (!$this->getRequest()->isPost()) {
        return $this->_forward('test1');
    }

    $form = $this->getForm();
    if (!$form->isValid($_POST)) {
        $this->view->form = $form;
        return $this->render('test1'); // go back to test1
    }
}

Indeed, the variable “name” is lost and the view is incorrect. Instead of saying “Hello Bob” it says “Hello”.

How should I handle that ? should I redirect to test1 instead of just rendering test1 again ? how ?

EDIT

Following the answer of Mr Coder, here is what I ended up with :

Controller:

    public function getForm() {
        // what is important is that the form goes to action test3 and not test4
        // SNIP form creation with a field username
        return $form;
    }

    public function test3Action()
    {
        $this->view->form = $this->getForm();
        $this->view->name = "Bob";

        if(!$this->getRequest()->isPost())return;

        if($this->view->form->isValid($_POST))
        {
            //save the data and redirect
            $values = $this->view->form->getValues();
            $username = $values["username"];

            $defaultSession = new Zend_Session_Namespace('asdf');
            $defaultSession->username = $username;

            $this->_helper->redirector('test4');
        }
    }


    public function test4Action()
    {
        $defaultSession = new Zend_Session_Namespace('asdf');
        $this->view->username = $defaultSession->username;
    }

test3.phtml

Hello <?= $this->name?>
<?php echo $this->form;?>

test4.phtml

success for <?php echo $this->username;?>

To bring your bob back do

public function test2Action() {
    if (!$this->getRequest()->isPost()) {
        return $this->_forward('test1');
    }

    $form = $this->getForm();
    if (!$form->isValid($_POST)) {
        $this->view->form = $form;
        $this->view->name = 'bob';        
        return $this->render('test1'); // go back to test1
    }
}

But I will advice my solution of handling form which goes something like

public function test2Action()
{

   $this->view->form = new My_Form();

   if(!$this->getRequest()->isPost())return;   

  if($this->view->form->isValid())
   {
    //save the data and redirect 
       $this->_helper->redirector('success');
   }

  }

inside your test2.phtml

<?php echo $this->form ?>

}

This approach save you from creating multiple action for saving one form and changing view manually.
