Possible to relocate a flag checkbox on node form into another fieldset?

Just move it to the new location:

$form['some_fieldset']['slideshow'] = $form['flag']['slideshow'];
unset($form['flag']['slideshow']);

However this will assign new parents to the element since it's been moved, you'll probably need to do the above plus adding in the original parents:

$form['some_fieldset']['slideshow'] = $form['flag']['slideshow'];
$form['some_fieldset']['slideshow']['#parents'] = array('flag', 'slideshow');
unset($form['flag']['slideshow']);

I ran into a similar issue when I was asked to combine two checkboxes within a single fieldset. One of those fieldsets was a CCK field, and other was created by the flag module. Initially they didn't want to play together. If I used hook_form_alter to move the CCK field into the flag's existing "flag" fieldset, I got an error message upon form submission. (I think this is because flag_nodeapi() assumes that each element inside $node->flag is going to be a flag, and therefore barfs if the flag fieldset contains anything that isn't a flag.) However, I got a different error if I tried to go the other way -- moving the flag into a fieldset with the CCK field.

After reading this discussion, I was able to combine the CCK field and the flag into a single fieldset using the following implementation of hook_form_alter. My CCK field is named "field_hide_upcoming_events", and my flag is named "feature_on_front_carousel":

function mymodule_form_alter(&$form, $form_state, $form_id) {
  if ( $form['#id'] == 'node-form' && $form['type']['#value'] == 'initiative' ) {
    // Some trickery to put CCK field_hide_upcoming_events in the same fieldset
    // as the feature_on_front_carousel flag
    $form['flag_plus'] = array(
      '#type' => 'fieldset',
      '#title' => t('Flags'),
      '#weight' => 0,
      '#collapsible' => TRUE,
      '#collapsed' => FALSE,
    );
    $form['flag_plus']['feature_on_front_carousel'] = $form['flag']['feature_on_front_carousel'];
    $form['flag_plus']['feature_on_front_carousel']['#parents'] = array('flag', 'feature_on_front_carousel');
    unset($form['flag']);
    $form['flag_plus']['field_hide_upcoming_events'] = $form['field_hide_upcoming_events'];
    unset($form['field_hide_upcoming_events']);
  }
}

Am I dreaming, or there is a module that listed the Flag like a field in a content type Manage Fields list?

This allows you drag and drop it to relocate it in the list.

I am pretty sure I used this on a previous site.

I must be crazy ... The Flag field is there in the site I work on, I believe it's a built in feature. I only seen it after I posted the above :-s

Does this also work when you create a forms API field (in this case an item field) and you want to insert it into an existing cck built fieldset?

If so, where would I get the info to populate the parent array that needs to be moved over, if, as far as I know, it has never been assigned to a specific prior parent?

How would this solution differ for Drupal 7?

I am also interested in a Drupal 7 version (got errors using the above mentioned code).

Here's some code that's working for me in Drupal 7. In my case I wanted to alter a blog entry form, to move a front_page_slideshow flag into a group_front_page_slideshow group. Sorry if that's confusing, it just happened to be the way the flag and group were named.

The group_front_page_slideshow group is a vertical tab group from the Field Group module.

function MODULE_NAME_form_alter(&$form, &$form_state, $form_id) {
  switch($form['#id']) {
    case 'blog-entry-node-form':
      // Get front_page_slideshow out of the flag array
      $form['flag_front_page_slideshow'] = $form['flag']['front_page_slideshow'];
      $form['flag_front_page_slideshow']['#parents'] = array('flag', 'front_page_slideshow');
      $form['#groups']['group_front_page_slideshow']->children[] = 'flag_front_page_slideshow';
      $form['#group_children']['flag_front_page_slideshow'] = 'group_front_page_slideshow';
      unset($form['flag']);
      break;
  }
}

A couple of things about this. I'm not sure if adding to the children array of group_front_page_slideshow is entirely necessary. It worked without it but all of the other fields were there so it made sense to me to set it there as well. Also, I've read where unsetting form items in D7 isn't the desired method, but anything else I tried resulted in the flag not being saved.

At the moment according to this issue, and what i found myself the flag module is not compatible with the field group module. If this module provides a field (and it does) it should also act like a field, meaning it should be possible to just drag it and it should appear where i dragged it to. To always put in form alters is not very nice.

I think the issue should be a feature request then.

Gosh I didn't know we had this kicking around.
