Create multiple step form in Drupal 6

Fri, Apr 24, 2009 by Sae 5 Comments

Multiple step form which consists of multiple steps or pages is useful sometimes. It allows you to create a form workflow and helps to make your web site user-friendly and flexible. For example, you can make different contents on next pages based on user inputs from previous pages.

function example_form_submit($form, &$form_state) {

  if($form_state['storage']['page'] == 1) {

    $form_state[‘rebuild’] = TRUE;

    $form_state[‘storage’][$page][‘values’] = $form_state[‘values’];

    $form_state['storage']['page']++;

  else {

     //process the data

  }

}
