[Plugin: Posts 2 Posts] Adding More Arguments to Query Posts

    I am trying to add a url rewrite rule that finds any posts that are connected to the current post. This is my rule that I am working with, but I don’t have the post_id as a part of my url, so I can’t get that via regex.

    add_rewrite_rule("cleats/([^/]+)/news", "index.php?tag=\$matches[1]", 'top');

    What I want to happen is show only related news articles. For instance, I have a Manchester United page (custom post type of club) at /clubs/manchester-united. I want /clubs/manchester-united/news to show a listing of blog articles that are connected to that post. Keeping it this way instead of via tags keeps me from having to doubly maintain a list of tags that exactly match the custom post types that I have.

    Where the query string for returning tags is as simple as ?tag=manchester-united, it works a little differently in my case. What I need is ?connected=45, where 45 is the post->ID of manchester-united. The regex in the rewrite rule above returns the slug “manchester-united”, but that isn’t enough information for my query.

    I would propose being able to pass in some other arguments into the query string. For example, instead of just an ID, maybe you pass in a post_type and a slug variable. To help be even more specific, you could also include a parent ID or parent slug. That would make a regex rewrite rule possible and scalable.

    What do you think scribu?

    You can achieve the desired result with the current query vars, as long as you can distinguish between the club page and the /news page:

    global $wp;
$wp->add_query_var('news');
add_rewrite_rule('clubs/([^/]+)/news', 'index.php?club=$matches[1]&news=1', 'top');

    Going to:

    /clubs/manchester-united/news

    is equivalent to going to:

    /clubs/manchester-united/?news=1

    Now, in your theme (single-club.php), you can look for the ‘news’ arg:

    <?php
if ( get_query_var('news') ) {
query_posts( array(
  'connected' => $wp_query->get_queried_object_id()
) );
}

    where $wp_query->get_queried_object_id() returns precisely the ID of the Manchester United club.
