In Drupal 7, how I can intercept menu rendering in template.php and add pipes after menu links?

I tried using template_preprocess_menu_tree but I don't think that is what I am looking for. I want to change the HTML structure of a couple of menus.

  • Are you talking of any menu link, or just to the menu local task links? – kiamlaluno Aug 12 '11 at 15:19
  • Custom menus, Main Menu, not local tasks. – Kevin Aug 12 '11 at 15:20

theme_menu_link() did the trick. It contains an array under element of #original_link which has the menu name in it. Using that, I can add pipe delimited links to certain menus.

This may be helpful. You can use preprocess functions to change or add something to menu link.

function THEME_preprocess_menu_link(&$variables) {
  $variables['element']['#below']['#markup'] = ' <span>→</span>';
}

In this code span added to every navigation link item.

Personally I'd just add the pipe with CSS - you don't really want the pipes in your markup as they're purely presentational:

.breadcrumb li:after {
  content: "|";
  margin: 0 5px; // optional styling nicety
}

.breadcrumb li:last-child::after {
  content: "";
}

Using HTML in a menu option would be very useful from a module too, i.e. inserting an image as a menu option. Is there a way to do use something like function MODULE_preprocess_menu_link(&$variables).

PS: I'll ask this as a separate question too.

Menus are themed with the theme_links function. You'll want to create a copy in your [themes folder]/MYTHEME/template.php and rename it to MYTHEME_links. You can find the default function for drupal 7 by visiting: http://api.drupal.org/api/drupal/includes--theme.inc/function/theme_links/7

Now you'll be able to customize how the menus look from the template.php file.

  • This isn't working either. It only dumps the contextual links (using krumo and var_dump on $variables). This is what I used in D6 pretty sure, but doesn't seem to touch menus in a menu block. – Kevin Aug 15 '11 at 13:35
  • I needed to only do this to certain menus, this answer helped. theme_menu_link contains an array about the menu it is in, so I could then adjust the output if it was a particular menu. stackoverflow.com/questions/2317462/… – Kevin Aug 15 '11 at 14:04
