Can't display custom menu using name?

Question

I want two menus using the new WordPress 3.0 feature.

In functions.php I have:

function register_my_menus() {
 register_nav_menus(
    array(
     'header-menu' => __( 'Header Menu' ),
     'top-menu' => __('Top Menu')
   )
 ); 
}

add_action( 'init', 'register_my_menus' );

And in header.php I have:

<?php wp_nav_menu( array( 'name' => 'Header Menu' ) ); ?>
....
<?php wp_nav_menu( array( 'name' => 'Top Menu' ) ); ?>

Now they seem to fallback or something, always showing the same menu. The menus have been defined and setup in wp-admin "theme-locations".

Why won't they load appropriately?

Answer 1

wp_nav_menu() does not have a name argument. Instead, you should use theme_location.

With register_nav_menus(), you indicate that you have two locations in your theme where you can display a menu. The user can then create multiple menus, and assign them to these locations. This is why we have the indirection via theme_location. If you know the ID, slug or name of the menu you want to use, you can use the menu argument of wp_nav_menu().
