I apologize if this is a difficult question to understand, but really it's a template hierarchy / rewrites question.

I have set up a few rewrite rules that are successful, but I'm hoping that I can manipulate them to call different template files in the hierarchy, so I can control archive pages more logically. I have a team-news custom post type, and a sport taxonomy. My goal is to have a team-news archive of posts only from a specific sport, and a separate sport archive for all posts and pages associated with that taxonomy. Unfortunately, I'm only able to access the sport taxonomy archive with my current rewrites, not the team-news CPT archive.

Here are my rewrite rules and an explanation of what I think happens:

add_rewrite_rule('^athletics/team/([^/]*)/news/?','index.php?post_type=team-news&sport=$matches[1]', 'top');

This one brings up taxonomy-sport.php, although I was hoping it would bring up archive-team-news.php. I need the sport= part, because I only want to show team-news posts for that sport.

add_rewrite_rule('^athletics/sport/([^/]*)/?','index.php?sport=$matches[1]', 'top');

This one rightly brings up taxonomy-sport.php as I had hoped.

According to the Query Monitor plugin, the template hierarchy when requesting the url /athletics/team/varsity-football/news/ is this:

  1. taxonomy-sport-varsity-football.php
  2. taxonomy-sport.php --- The one it's using
  3. taxonomy.php
  4. archive-team-news.php --- The one I want it to be
  5. archive.php
  6. index.php

Is there any way to make archive-team-news.php work for that URL? Would I need to filter the hierarchy? I'm pretty new to WP, so I don't want to change up too much...

EDIT 1: To simplify my goal --

?post_type=[1]&taxonomy=[2] will always pull up a taxonomy archive page, as far as I can tell. Can I make it pull up the post-type archive page instead?

EDIT 2: I've changed the 2nd parameter of the first rewrite rule to 'index.php?post_type=team-news', and now the correct archive page is being displayed (archive-team-news.php) but I still need to filter further by taxonomy somehow.

NOTE: the taxonomy slug is in the URL as athletics/team/[taxonomy]/news/, so now I'm trying to parse the URL for that value in PHP, but I'd prefer a WP solution (less hacky).

  • if you change the order in URL, does it change something index.php?sport=$matches[1]&post_type=team-news ? – mmm Nov 16 '17 at 22:29
  • Good idea, but no. That's what I had at first, so I thought if I "prioritized" the post type by putting it first, it might work, but it didn't. :/ – Peter Arthur Nov 16 '17 at 22:41
  • One thing you can try is to use a custom query var to pass the tax slug, then hook pre_get_posts to manually add the tax query. Another possible solution is to hook parse_query and force a post type archive. You could filter the hierarchy as you mention, but it’ll still be identified as a tax archive in things like body_class. – Milo Nov 17 '17 at 2:34

I handled this with a pre_get_posts hook (thanks, @Milo), passing in the URL part that corresponds to the slug I need. Hope this helps someone down the road. Improvements are welcome. Thanks.

function filter_team_news_archives_by_sport_taxonomy($query) {

    if (is_post_type_archive('team-news') && $query->is_main_query()){

            // Get $sport_slug from URL  --  https://stackoverflow.com/a/36002190/4107296
            $url = (isset($_SERVER['HTTPS']) ? "https" : "http") . "://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
            $parsed = parse_url( $url );
            $chunks = explode( '/', trim($parsed['path'],'/') );
            // if the URL is in this format: /athletics/team/[sport-slug]/news 
            if ($chunks[0] === 'athletics' && $chunks[1] === 'team' && $chunks[3] === 'news') {
                $sport_slug = $chunks[2];
                $query->set('tax_query', array(array(
                    'taxonomy' => 'sport',
                    'field'    => 'slug',
                    'terms'    => $sport_slug,
                )));
            }
    }
}

add_action('pre_get_posts', 'filter_team_news_archives_by_sport_taxonomy');
