display menus on all page except one?

Question

I'm not very good at this, so please bear with me. I have a Wordpress site with sections for different cites, and the different cities each have their own nav menu which shows for all of the pages in that city.

if ( is_page( 'phnom-penh' ) || in_array( '11760', $ancestors ) ) :
    get_sidebar( 'city-phnom-penh' );

However, I want to remove the menu/sidebar just from one page in the Phnom Penh section so I can add a widgetized sidebar to that page instead. Is it possible to have this sidebar apply to all pages in that section except for one?

Answer 1

As I noted in my comment, you can use the negation operator, like so:

if ( ! is_page( 'phnom-penh' ) ) {
    get_sidebar( 'not-phnom-penh' );
} else {
    get_sidebar( 'phnom-penh' );
}

Note the ! before the is_page - that means NOT.

Also note that if you use more than once condition via || or OR and either of the conditions returns true - the sidebar will be returned.
