texas-bronius's sandbox: References Dialog: Checkboxes

Provides support for node or entity references as checkboxes for the references_dialog project.

Implements hook_references_dialog_widgets() to take advantage of all the great work on References Dialog:

function references_dialog_checkboxes_references_dialog_widgets() {
  return array(
    'options_buttons' => array(
      'element_type' => 'container',
      'format' => '$label [nid: $entity_id]',
      'views_query' => 'references_dialog_node_reference_views_query',
      'operations' => array(
       'add' => array(
          'function' => 'references_dialog_node_reference_add_link',
          'title' => t('Add dialog'),
        ),
      ),
    ),
  );
}

This sandbox project is out here to share and improve: Currently it makes an assumption about one of the field names for callback.

Status

• Works with API via hook_references_dialog_widgets() to present to parent module references_dialog. This means no contrib module changes were required.
• Adds Create [entity-type] link to the bottom of a configured checkboxes nodereference
• On dialog successful submit and closure, ajax refreshes list of checkboxes
  ..albeit like crawling through a den of snakes..
• Has a hardcoded fieldname specific to my use case/project
