I'd like to replace the link title on the top link of my secondary navbar (called "explorer", links to "mysite.net/explorer", but actually just triggers a dropdown-menu) with a glyphicon and the current user's name.

According to this thread, a title callback is the way to do this. However, adding this code in my template.php has no effect at all.

function mythemename_menu_alter(&$items) {
  $items['explorer']['title callback'] = 'mythemename_title_callback';
}

function mythemename_title_callback($arg1, $arg2) {
  global $user;
  $title = '<span class="glyphicon glyphicon-user" aria-hidden="true"></span>'. $user->name;

  return $title;
}

What am i doing wrong? And why does the callback function take 2 parameters? (It doesn't work with 1 or 0 params.)

The "menu token" module almost crashed my site after installation, so I don't want to use that.

  • Is mysite.net/explorer added by a module, or does it point to a page you created, including a view? – kiamlaluno Jan 24 '15 at 17:57

One way is to use theme_menu_link(). Use debug() or Devel's dpm() to browse through $variables in order to get a grip on how the array is structured. Then locate the particular menu link in your code and theme it to your requirements. In the API documentation there are plenty of examples in the comment area that may suit your needs.

  • Theme functions should be used to alter the way an element is rendered, not to alter a link title. Eventually, the OP should use a preprocess function, but I think an alter hook should be used. – kiamlaluno Jan 24 '15 at 18:07
  • Sure. I should have said 'One quick but dirty way'. – Wtower Jan 25 '15 at 9:29

If you only want to change the title of an menu item, you should be able to do this through the administration. Go to admin/structure/menu and edit the correct item in your secondary menu.

To use hook_menu_alter() you must add it in a custom module not inside your template file. Remember to clear you cache in order for the changes to take effect. To clear the cache you can goto admin/config/development/performance.

  • Themes can implement alter hooks. The problem is that hook_menu_alter() is used to alter what hook_menu() returns, not to alter links added within the user interface. – kiamlaluno Jan 24 '15 at 17:29
  • @kiamlaluno - I tried adding it to my own template file and cleared my cache, but the hook never seemed to be called, so I assumed that one was forced to use a custom module for this. – Cyclonecode Jan 24 '15 at 17:30
  • See drupal_alter(), the code after the "Allow the theme to alter variables after the theme system has been initialized" comment. It is adding $theme_key . '_' . $hook to the $functions[$cid] array of the called functions. – kiamlaluno Jan 24 '15 at 17:36
  • @kiamlaluno - Strange I cant get it to work? Hm I must have made some kind of error. – Cyclonecode Jan 24 '15 at 17:38
