Hi Darren,

So you are trying to make that URL:

https://creativecamera.online/courses-photography-ideas/

To:

https://creativecamera.online/courses/photography-ideas/

In this case you can only make with custom coding because WordPress doesn't allow adding forward slashes in permalinks.

Optionally, you can make all portfolio items with prefix /courses in Theme Options > Portfolio Settings > Portfolio Page > URL Rewrite Options:

But then all portfolio items will have /courses prefix. Will that work for you?

I've added the following code in functions.php of child theme:

// Custom rewrite URL (The first parameter is how you want the URL to be.)
add_action( 'init', function() {
    add_rewrite_rule( '^courses/photography-ideas/?', 'index.php?portfolio=courses-photography-ideas', 'top' );
} );

https://creativecamera.online/courses/photography-ideas/

Please note that if you change the slug of that portfolio item you have to replace it in index.php?portfolio=your-new-slug

Hi Darren,

For custom URL structure like that it requires custom coding, so I am giving you an idea how you can change the appearing URL of that item, so by adding:

add_filter( 'wp_setup_nav_menu_item', function( $menu_item) {
    if ( $menu_item instanceof WP_Post && strpos( $menu_item->url, 'courses-photography-ideas' ) !== false ) {
        $menu_item->url = home_url( 'courses/photography-ideas/' );
    }
    return $menu_item;
} );

In the menu will look like:

https://d.pr/v/TLNtZZ

So based on this pattern you can replace for other pages. 

Note that this is custom code, since we do not provide custom work in support I gave you this time to help you out of support scope.
