Custom Rewrite Rules Problem.

Hello, I’m using 3.8.1, my custom theme based off _s, local copy.

I’m using Rewrite API to create a simple rule. I have a page on my site, example.com/db-admin. This is a page created by WordPress, ie. index.php?p=5487 or whatever. I want to display different things on this page, based on custom query vars, as is the WP way.

So example.com/db-admin/123456/edit would actually be index.php?p=5487&tour_number=123456&tour_page=edit.

So I created the following rules:

function eadb_add_rewrite_rules(){
    global $wp_rewrite;
    $wp_rewrite->add_rewrite_tag( '%tour_number%', '([0-9]{6}})', 'tour_number=');
    $wp_rewrite->add_rewrite_tag( '%tour_page%', '(edit|add|registry)', 'tour_page=');

    $wp_rewrite->add_rule( '^db-admin\/([0-9]+)\/(edit|add|registry)', 'index.php?p=10300&tour_number=$matches[1]&tour_page=$matches[2]', 'top');

    flush_rewrite_rules();
}
add_action( 'init', 'eadb_add_rewrite_rules' );

However, the query vars created were never passed to the page, and the url was usually rewritten incorrectly. I have tried variations for the regex, but I don’t that’s the problem. Right now, with what I have above, I see my rule in the rules array of the global rewrite object, and my tags as empty query vars. However, when requesting the url in the structure I have above ( example.com/db-admin/123456/edit ) the matched rule is:

(.?.+?)(/[0-9]+)?/?$ | index.php?pagename=$matches[1]&page=$matches[2]Array

…so I am at a loss. Any help would be killer. Thanks.
