Set a main-menu item as active with custom code

Question

I want to set a menu item of the main menu as active (class="active").

I'm specifically looking for a hook or function, not a contrib module.

I have seen recommendations for Context, and I have looked in the module code, but it uses hooks which I cannot find on the API-Site.

Answer 1

If you simply want to add the 'active' class to a menu item you could do it in the code before printing the menu. If you want the menu item to also act like an active item you could use menu_tree_set_path() that was supposedly added in Drupal 7.9.

In earlier versions and Drupal 6 I used this:

function mymodule_init() {
  $item = menu_get_item($_GET['q']);
  $item['href'] = 'node/1';
  menu_set_item(NULL, $item);
}

However both options just add the 'active-trail' (not 'active') class(es), but that should suffice in most cases.

Answer 2

You could use menu_set_active_trail to set which menu should be rendered as active.

Another way is to mess with $_GET['q'], but you really want to avoid that if at all possible, since it can lead to some strange bugs.

Answer 3

My solution is this:

function mymodule_init() {
    $link=menu_link_load(346);
    $link["options"]["attributes"]["class"]="active";
    menu_link_save($link);
}

The id 346 is the mlid no idea what this mean but I got this id with this little dump:

echo('<pre>');
dump(menu_tree_all_data('main-menu'));
echo('</pre>');

You can also use hook_translated_menu_link_alter()

/**
 * Implements hook_translated_menu_link_alter()
 */
function Module_translated_menu_link_alter(&$item, $map) {

    if ($item['menu_name'] == 'menu-name') {

        //check first two arg from url
        $path = arg(0)."/".arg(1);

        //add class active-trail if path match
        if (strpos($item['link_path'], $path) !== false) {
            $item['in_active_trail'] = true;

        }

    }
}
