WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I use a menu on top of my wordpress which shows 3 links.

  1. Main page
  2. Custom Page
  3. Custom Page

Can I add a 4th link to my menu which is visible and accessible to admins only (without plugins)? This 4th page would also be a custom page I make. How would I go about setting this up, or does anyone have somewhere to start?

Saying without plugins is akin to saying without code. –  Wyck Jun 18 '13 at 3:50
    
How is your menu output in your theme, is it a Navigation Menu, or wp_list_pages, or? –  Milo Jun 18 '13 at 3:58
    
@Wyck Maybe I used bad wording, but basically I don't want to use someone elses code added as a plugin. I want to edit the php pages myself if that makes sense. The information is sensitive and I don't like blindly trusting plugins which I don't really know about. –  Cully Jun 18 '13 at 5:55
    
@Milo I'm not sure what you mean. Here's what loads the menu on my header.php: echo theme_get_menu(array('source' => theme_get_option('theme_menu_source'), 'depth' => theme_get_option('theme_menu_depth'), 'menu' => 'primary-menu', 'class' => 'fmls-hmenu')); Does that answer your question? –  Cully Jun 18 '13 at 5:57

You can show or hide something based on a user's role with the current_user_can() function. For the Administrator role you would check if current_user_can( 'administrator' ).

Here's a quick and dirty example of hiding a nav menu item by first checking if the title matches a particular page, and then checking if the current user is not an administrator, via the wp_nav_menu_objects filter. If both conditions are satisfied, the menu item is removed via php's unset.

function wpa_filter_nav_menu_objects( $items ){
    foreach( $items as $key => $item ){
        if( 'Private page' == $item->title && !current_user_can( 'administrator' ) ){
            unset( $items[$key] );
        }
    }
    return $items;
}
add_filter( 'wp_nav_menu_objects', 'wpa_filter_nav_menu_objects' );

Please remember, the title of the page is case-sensitive. –  gurung Mar 27 at 17:19
