HS menu: Exclude current node form the option list

This patch doesn't work (anymore?). The $exclude parameter of _hs_menu_apply_config() expects an array of the menu name and item.

The form_alter function needs to be:

/**
 * Implements hook_form_FORMID_alter().
 *
 * Alter the node form's menu form.
 */
function hs_menu_form_node_form_alter(&$form, &$form_state) {
  if (isset($form['menu']['link']['parent']) && $form['menu']['#access']) {
    unset($form['menu']['link']['parent']['#options']);
    $form['menu']['link']['parent']['#type'] = 'hierarchical_select';
    // Get menu name, needed to exclude current node
    $menu_name = explode(':', $form['menu']['link']['parent']['#default_value']);
    _hs_menu_apply_config($form['menu']['link']['parent'], array($menu_name[0], $form['menu']['link']['mlid']['#value'])); // Exclude current node

    // Set custom submit callback.
    array_unshift($form['#submit'], 'hs_menu_node_form_submit');
  }
}

New patch is attached with some small changed to previous comment.

Hello,
we have this issue and it's very prone the crash even whole server if user selects the node itself as parent. I improved the patch a little bit HOWEVER it seems that exclude doesn't work for some reason (Also the additional function $params['exclude'] was always empty so added creation of that). As working solution for now this has jQuery based (inline) failsafe to remove node itself from the parent list.

Committed, thanks!

Possible regression: #2734499: All menus available when selecting the Parent Item
