function admin_menu_init in Administration menu 6.3

Same name and namespace in other branches

1. 6 admin_menu.module \admin_menu_init()
2. 7.3 admin_menu.module \admin_menu_init()

Implements hook_init().

We can't move this into admin_menu_footer(), because PHP-only based themes like chameleon load and output scripts and stylesheets in front of theme_closure(), so we ensure Admin menu's styles and scripts are loaded on all pages via hook_init().

File

./admin_menu.module, line 220

Render an administrative menu as a dropdown menu at the top of the window.

Code

function admin_menu_init() {

  // the active menu name. Also applies to users without access to the
  // Administration menu as they should also get properly working breadcrumbs on
  // administrative pages.
