I'm trying to swap out the main menu of a page if it uses a specific page template.

This was working perfectly until I added a 2nd menu to the page.

I would greatly appreciate any guidance on how to target only the primary-menu and not all the menus on the page. I tried 'primary-menu' but did not work.

In functions.php:

add_filter('wp_nav_menu_args', function ($args) {
  if (is_page_template('page-template-custom.php')) {
    $args['menu'] = 'custom-menu';
  }
  return $args;
});

Thanks very much!

• 1 Does this answer your question? Two different menus for two different locations? – Michael Commented Mar 13, 2020 at 22:55
• Thanks is brilliant! Thank you Michael! I had to make a small modification though as the brackets may be misplaced and swapped "is_page" with "is_page_template" and voila! – Chumtarou Commented Mar 14, 2020 at 0:45

The $args the filter is receiving includes the theme_location used when the menu was registered, so assuming your main location is primary, you can add the following to your if statement to target only that menu:

    if ( 
      is_page_template( 'page-template-custom.php' ) && 
      isset( $args['theme_location'] ) &&
      'primary' === $args['theme_location'] )
    ) { ...
