Custom Permalink Structure with Custom Post Types Using Custom Taxonomies

Question

After a pretty exhaustive search, I'm stumped.

I have a Wordpress custom post type named: listings. Listings have taxonomies called Services and Areas.

The default structure is

/listing/%post-name%

I'm trying to achieve a structure that looks like:

/%services%/%areas%/%post-name%

I was able to achieve something close using the plugin Custom Post Type Permalinks which gives me this working URL:

/listings/%services%/%areas%/%post-name%

And then used the code

function gp_remove_cpt_slug( $post_link, $post, $leavename ) {

    if ( 'listing' != $post->post_type || 'publish' != $post->post_status ) {
        return $post_link;
    }

    $post_link = str_replace( '/' . $post->post_type . '/', '/', $post_link );

    return $post_link;
}
add_filter( 'post_type_link', 'gp_remove_cpt_slug', 10, 3 );

That shows a permalink of what I want when I edit the listing but there's a 404 error when I go to that URL. I'm not sure where to go from here. Please help.

A simple solution would be using the rewrite and 'with_front arguments while registering the post type. Try this..

'with_front' => false,
'rewrite' => array( 'slug' => '%services%/%areas%'),

Then add a filter to post_type_link to replace the tags with terms.

function wpse277778_rewrite_urls( $url, $post ) {

   if ( 'listings' == get_post_type( $post ) ) {
        $services = wp_get_post_terms( $post->ID, 'services' );
        $areas = wp_get_post_terms( $post->ID, 'areas' );

        $url = str_replace( '%services%', $services[0]->slug, $url );
        $url = str_replace( '%areas%', $areas[0]->slug, $url );


    }
    return $url;
}
add_filter( 'post_type_link', 'wpse277778_rewrite_urls', 10, 2 );

Please note, this is a barebone code and you need to do some checking with conditional tags to output error free $url. Also, you should set a default services and area in case no terms are associated.
