How do I print a menu with links generated by my custom module?

Question

If I use

theme('links', array('links' => menu_navigation_links('main-menu'),
'attributes' => array('class'=> array('links', 'main-menu')) ));

It will print the links in my Main Menu. I need to print the links that are created by my custom module, but I do not know what the system menu name is.

For instance:

 //hook_menu
 function custom_menu() {

     //admin page
     $items['admin/custom'] = array(
     'title' => t('Custom Admin Page'),
     'description' => t('Manage Custom Module'),
     'page callback' => 'custom_admin_page',
     'access arguments' => array('access toolbar'),
     'type' => MENU_NORMAL_ITEM,
     );

     //add event
     $items['admin/custom/add'] = array(
     'title' => t('Add Custom'),
     'decription' => t('Add custom'),
     'page callback' => 'custom_add',
     'access arguments' => array('add custom'),
     'type' => MENU_NORMAL_ITEM,
     'file' => 'custom_add.inc',
     'file path' => drupal_get_path('module', 'custom') . '/includes',
     );

The page 'admin/custom' automatically goes into my administration menu, and the page 'admin/custom/add' is seen under the admin/custom link when viewing all of the links in the administration menu, but I want to print that menu (admin/custom) on the 'admin/custom' page so that I can see the link 'admin/custom/add'.

Answer 1

Menus and paths are slightly different things...in hook_menu() you're defining paths that can be consumed; menus create the links to those paths - the two concepts aren't necessarily related (a path can exist without a menu link).

You can assign a particular router path to a menu using the menu_name property in your hook_menu() items, but that menu needs to exist already.

Fortunately Drupal provides a method for adding links to the top of a page through hook_menu(), and you only need to change one line:

$items['admin/custom/add'] = array(
  'title' => t('Add Custom'),
  'decription' => t('Add custom'),
  'page callback' => 'custom_add',
  'access arguments' => array('add custom'),
  'type' => MENU_LOCAL_ACTION, // <-- This one changed
  'file' => 'custom_add.inc',
  'file path' => drupal_get_path('module', 'custom') . '/includes',
);

That will put a link to 'Add Custom' at the top of the 'admin/custom' page; if you're using the Seven theme for administration it'll look like the 'Add Content' link on the content admin page:

You should see hook_menu path added to navigation menu not showing up.

You need to change the following line of code.

'type' => MENU_NORMAL_ITEM,
