Custom permalink – append taxonomy name and term name at the end of permalink

You can achieve the following permalink structure by simply overriding (without having to remove) the default one (you specified) for the resources post type:

/resources/%resources%/resources-type/%resources_type% <- preferred
/resources/resources-type/%resources_type%/%resources% <- default

And you can override it via add_permastruct() — first, register the post type without specifying the rewrite parameter which means the rewrite defaults to true/enabled and that the slug would be resources (i.e. the post type key or slug):

register_post_type( 'resources', array(
    'label' => 'Resources',
    'public' => true,
    // no need to set the 'rewrite' arg
    ...
) );

Then right after that, override the permalink structure like so:

add_permastruct( 'resources', '/resources/%resources%/resources-type/%resources_type%' );

where the format is — the important part is the {POST TYPE KEY}, which in your case is resources:

add_permastruct( '{POST TYPE KEY}', '{PERMALINK STRUCTURE}' );

(Don’t forget to flush the rewrite rules — just visit the permalink settings page.)

How to disable /resources/%resources%

/resources/%resources% (i.e. /{POST TYPE KEY}/%{POST TYPE KEY}%) is automatically added if %{POST TYPE KEY}% is found in the permalink structure. You can remove it like so:

add_filter( 'resources_rewrite_rules', 'filter_resources_rewrite_rules' );
function filter_resources_rewrite_rules( $rules ) {
    $pattern = 'resources/([^/]+)/resources-type/';
    $p_length = strlen( $pattern );

    foreach ( $rules as $regex => $query ) {
        if ( $pattern !== substr( $regex, 0, $p_length ) ) {
            unset( $rules[ $regex ] );
        }
    }

    return $rules;
}

If the post type is hierarchical, then the $pattern would be resources/(.+?)/resources-type/.

And if you’d like to use the above code/function with another post type, you basically only need to replace the text “resources” with the proper post type key.

See https://developer.wordpress.org/reference/hooks/permastructname_rewrite_rules/ for more details on that filter.
