I'm asking myself, where is the code that hides "My account" & "Log out" in the user menu? Just curious, to learn from that code. Any way to know where to search if you want to know something like this?

I added a "Log in" link to this menu, and I want to hide this when nobody is logged in.

When you have something that happens with a link, you need to look in the code for a hook_menu(). Then you need to guess which module it is in. In this case, take a look at core User module:

function user_menu() {
  $items['user/login'] = array(
    'title' => 'Log in',
    'access callback' => 'user_is_anonymous',

  return $items;

Note the 'access callback' => 'user_is_anonymous', line. This means that you can only do this if you are anonymous (ie, not logged in). This means that you should just be able to make a menu entry with "user/login" as the path, and the link will only show when you are logged out.


You can add a menu link to user/login, the access callback of that verifies that it is only shown to anonymous users. Just like user/logout is only visible for logged in users.

The definition of these callbacks() are, as mentioned in the other answer, in user_menu()

  • +1 and the same is true for user/register - create the link the usual way through the menu UI, and it only appears for users who aren't logged in automatically. Commented May 17, 2016 at 16:05

Check the menu definitions in user_menu() in user module. The access callback determine, when will the menu item be shown.
