Set a CPT slug as a base name for all the taxonomies

Question

I'm looking for help because I tried to look on the web for a solution but I can't to solve my 404 page issue.

I'm bulding a custom WordPress plugin for my photo club. This plugin wants to display portfolio for each members. Picture are classified by :

• Author (photographer)
• Color
• Theme (the category)

I created a custom post type ms_photo_porfolio and the 3 taxonomies :

• ms_photo_author for the taxonomy Author
• ms_photo_color for the taxonomy Color
• ms_photo_cat for the taxonomy Theme

I want to set the slug /photographies/ of the custom post type as a basename for these 3 taxonomy slugs.

These URLs actually work :

• thewebsite/photographies/
• thewebsite/themes/
• thewebsite/couleurs/
• thewebsite/membres/

I created 4 pages, and created the template files as index pages.

However I want to transform these URLs to :

• thewebsite/photographies/
• thewebsite/photographies/themes/
• thewebsite/photographies/couleurs/
• thewebsite/photographies/membres/

I set the parent page Photographie for last 3 pages but these pages leads to a 404 page. It's vital to keep a hierarchical structure for a good SEO.

I know there are a lot of subjets about this issue but I'm confused and lost. I don't want to install a plugin in order to fix my problem (security issues).

Here is the code used in order to register my CPT and taxonomies :

     function ms_register_post_type() {
  $gallery_labels = array(
            'name'                  => _x( 'Photographies des membres', 'Post type general name', 'ms-photo-gallery' ),
            'singular_name'         => _x( 'Galerie', 'Post type singular name', 'ms-photo-gallery' ),
            'menu_name'             => _x( 'Galeries', 'Admin Menu text', 'ms-photo-gallery' ),
            'name_admin_bar'        => _x( 'Galeries', 'Add New on Toolbar', 'ms-photo-gallery' ),
        );
        $gallery_args = array(
            'labels'             => $gallery_labels,

I think if you change the rewrite in your register_taxonomy $args

'rewrite' => array( 'slug' => 'photographies/couleurs','with_front' => false  ),

This will probably clash with rewriting the custom post type so you'll more than likely get a 404 on this url: http://thewebsite/photographies/ but if you don't need that url then this solution will help you get closer to what you want but I'm pretty sure: http://thewebsite/photographies/couleurs/ will always give you a 404 as within a taxonomy you'll need to create terms then you can link to a page with those terms e.g. http://thewebsite/photographies/couleurs/black-and-white.
