I am using form Api to create a custom form. My form is below.

function myform_form() {
  $form = array();
  $form['name'] = array(
    '#type'          => 'textfield',
    '#title'         => t(''),
    '#required'      => FALSE,
    '#weight'        => 2,
   $form['telephone'] = array(
    '#type'          => 'textfield',
    '#title'         => t(''),
    '#weight' => 3,
     $form['submit'] = array(
      '#type' => 'submit',
      '#value' => t('submit'),
  return $form;

function myform_submit($form, &$form_state) {
  drupal_set_message(t('Your form has been submitted successfully.'));
  $form_state['redirect'] = 'thankyou';

I used to show this form in lightbox as this :

<a href="/myform" rel="lightframe"> Form </a>

Form is correctly showing in lighbox. But when i submit the form it opens the thankyou page in popup.

I used

<a href="/myform" rel="lightmodal"> Form </a>

It closes the popup event if form validation returns false. I don't want to close the popup if there is any validation error. I added this to myform_submit function :


But drupal_add_js is not working in myform_submit function.

Updated :

I send a parameter to thank you page and added this on the page load.

<?php if($_GET['redirect']) { ?>
      window.parent.location = "quick_request_quote";
<?php } ?>

Its redirecting but it shows content in popup for few seconds and redirect after that. I don't want to display popup for a second also after submitting the form.

Solved this by creating a Menu showing processing message and redirect it using :

      window.parent.location = "thankyoupage";

Hope this will help you,

For forms validation on modal dialog you can user Chaos tool suite module.


  • Download and enable Chaos tools and Chaos Tools (CTools) AJAX Example
  • Go to the URL your_site/ctools_ajax_sample
  • You can refer ctools dialog form examples using sites/all/modules/contrib/ctools/ctools_ajax_sample
    • Where contrib is the folder where I keep all my contributed modules.
  • 5
    Could you please explain how to use ctools for that effect? It's a big and complicated set of tools, just pointing at it will be useless for at least some readers.

  • Better now. I did not downvoted you so I cannot un-downvote, and it's still hardly anything but pointing at examples, so I'm not so sure if it deserves upvote. Let's leave it to downvoters and question's author.
