Unregister Nav Menu from Child-Theme

Question

I like to use the Starkers Theme and build child-theme.

So, I`d like to remove the this primary menu

Starkers (functions.php)

function starkers_setup() {
// This theme uses wp_nav_menu() in one location.
register_nav_menus( array(
'primary' => __( 'Primary Navigation', 'starkers' ),
) );


}
endif;

My child-theme functions.php looks like this:

unregister_nav_menu( array(
'primary' => __( 'Primary Navigation', 'starkers' ),
));

// my new nav
register_nav_menus(array(
'primary_navigation' => __('Main', 'starkers'),
'utility_navigation' => __('Meta', 'starkers')
));

But it doesn´t work for me.

What´s wrong?
Thanks

Answer 1

The Starkers theme setup is hooked to after_setup_theme, at a priority of 10. So you basically have to wrap the unregister function inside another function (child themes functions.php file) and add it later than the parent themes setup function, so it gets first added by the parent and later on removed by the child.

function wpse_remove_parent_theme_locations()
{
    // @link http://codex.wordpress.org/Function_Reference/unregister_nav_menu
    unregister_nav_menu( 'primary' );
}
add_action( 'after_setup_theme', 'wpse_remove_parent_theme_locations', 20 );

This should definitely work for you, I just checked out

add_action( 'after_setup_theme', 'remove_default_menu', 11 );
function remove_default_menu(){
unregister_nav_menu('primary');
}
