Let's say I have an AJAX callback setup using admin-ajax.php that fetches WordPress posts when query parameters are passed in the URL. A typical URL for an AJAX call using the GET method would look like:

http://example.com/wp-admin/admin-ajax.php/?action=get_posts&user_id=1

Now I would like to rewrite this to something like:

http://example.com/rest/posts/1

I'm able to rewrite URL for pages using WordPress native generate_rewrite_rules hook. But that doesn't work for admin-ajax.php as Wordress hasn't even loaded when admin-ajax.php is called. Any ideas on how to get this setup?

  • I did try earlier, the htaccess hack that you suggested in the answer that you linked. Though it serves the purpose of rewriting the AJAX url to a different location, I'm not sure how it could be modified to map "multiple" query parameters. Like in example above posts should refer to action=get_posts and 1 should refer to user_id=1. And if I have an additional query parameter, let's say page then that should also map correctly.

  • Inspect $_SERVER['REQUEST_URI'] like in the second link.

  • I took a look at the second link but could not find anything relevant to $_SERVER['REQUEST_URI']. Am I missing something?

  • The method get_api_values() does it: strtok( $request, '/' ); separates the values from each other.
