Saves the collapsed state of a Drupal collapsible fieldset.

Code

  // Check if user can save fieldset state
  // and confirm that the form is not the test form.
  if (!user_access('save fieldset state') && $form_id != 'fieldset_helper_test') {

  // If the $form object has an id, which will be used in the <form> tag,
  // then replace the $form_id variable.

  // Check the auto_exclude list of forms that do not have collapsible fieldset.
  // This insures that all the below recursive code is only executed on forms that
  // have collapsible fieldsets.
