Re: [fw-general] how to retain value in form using zend

[Ivan Ruiz Gallego]

Hi Steven,

Using sessions to store form data may lead to data overlapping. That's a 
good point, I didn't take into account. The main point using the session 
was to store form data in case that we have a preview action. In this 
case form data is no longer in the post array. What would be in your 
opinion the best way to store data in this case? Thanks.

Best regards,
Ivan.

people will be using the same form (or multiple forms) in multiple windows,
this results in overlapping data.

Check out this tutorial:

It has a really good example application for forms.

Cheers,
Steven

Hi Rohit83,

I usually use Zend_Session to keep form data between requests. I 
serialize the post array an keep it in an own session namespace. 
Additionally, I pass the form data array to the view in the controller 
action, so that the view does not need to know about the existence of 
sessions. Take a look at the sample code below.

If everyone has a better idea, I would be happy to know!

Best regards,
Ivan.

/* Display form */
public function displayformAction() {
        $this->initView();
        // Check session for form data
        $formSession = new Zend_Session_Namespace('form');
        if (isset($formSession->formData)) {
            $formData = unserialize($formSession->formData);
            $this->view->formData = $formData;
        }
        /* Render form */
}

/* Check user input */
public function checkformAction() {
          // Get POST data
        $request = $this->getRequest();
        $post = $request->getPost();

          /* Validation logic */

          /* If errors, go back to view */
          // Pass error message...
          $this->view->formData = $post;
         // Redirect

       /* If input ok */
       $formSession = new Zend_Session_Namespace('form');
       $formSession->formData = serialize($post);
       // Go to previewAction, e.g.
}

  
Hi All
        I have developed a form using zend framework.When i click on
    
submit
  
button and id if due to validation some error message is displayed , at
    
that
