How to enable menu link when creating a new node?

Question

I try to enable the menu link programmatically, here is how I do it:

function create_menu_link() {
    $node = new stdClass();
    $node->type = 'mytype';
    node_object_prepare($node);

    $node->menu['link-title'] = $menu_title;

    node_save($node);
}

But setting only the title is not working. In $node->menu there is some other variables like mlid and plid which are set to 0 it has to do with this ? The menu_name is set to main-menu:0, module is set to menu.

Answer 1

You'll need to create the menu item separately, using menu_link_save

$item = array(
  'menu_name' => 'main-menu',
  'link_title' => $node->title,
  'link_path' => 'node/'. $node->nid,
);
menu_link_save($item);

Answer 2

You don't have to create the link manually. The menu_node_save() hook will take care of link creation automatically when saving the node, if you provide the following variables:

  $node->menu['enabled'] = TRUE;
  $node->menu['link_title'] = t('My title');
  $node->menu['description'] = ''; // Needed even if empty to avoid notices.
