How to add new tab in user edit page drupal

Question

How can i add a new tab in user edit page. In user view page it is coming , but user edit page is not giving any result.

function usermail_menu() { 
$items = array();
$items['user/%/invoice'] = array(
    'type' => MENU_LOCAL_TASK,
    'title' => 'Subscription Invoice',
    'page callback' => 'usermail_invoice',
    'access callback' => 'user_is_logged_in',
    'weight' => 3 
);
return $items;
}

This is working correctly. For user edit page i changed the path as

function usermail_menu() { 
$items = array();
$items['user/%/edit/invoice'] = array(
    'type' => MENU_LOCAL_TASK,
    'title' => 'Subscription Invoice',
    'page callback' => 'usermail_invoice',
    'access callback' => 'user_is_logged_in',
    'weight' => 3 
);
return $items;
}

But it is not coming. Please help me. Do i want to add something else?

Answer 1

In user.module I saw

$items['user/%user/edit'] = array(
    'title' => 'Edit',
    'page callback' => 'drupal_get_form',
    'page arguments' => array('user_profile_form', 1),
    'access callback' => 'user_edit_access',
    'access arguments' => array(1),
    'type' => MENU_LOCAL_TASK,
    'file' => 'user.pages.inc',
);

So user/%user/edit will be considered as a parent menu item.

Try this:

function usermail_menu() { 
  $items = array();
  $items['user/%/edit/invoice'] = array(
    'type' => MENU_LOCAL_ACTION,
    'title' => 'Subscription Invoice',
    'page callback' => 'usermail_invoice',
    'access callback' => 'user_is_logged_in',
    'weight' => 3,
  );

  return $items;
}

MENU_LOCAL_ACTION allows you to add actions on the parent item.

Clear menu cache after making changes.

You just need one item only. Please make the following change

$items['user/%user/invoice'] = array(
    'type' => MENU_LOCAL_TASK,
    'title' => 'Subscription Invoice',
    'page arguments' => array('user', 1),
    'page callback' => 'usermail_invoice',
    'access callback' => 'user_is_logged_in',
    'weight' => 3 
);
