You can use add_rewrite_endpoint, which will add a query var and generate the necessary rewrite rules:

function wpd_cid_endpoint() {
    add_rewrite_endpoint( 'cid', EP_PERMALINK );
add_action( 'init', 'wpd_cid_endpoint' );

Don't forget to flush rewrite rules after changing rules. You can do this quickly by visiting the Settings > Permalinks page in admin.


You would need to create a custom rewrite rule that maps not just the post slug but also the cid value, see this article:


And the relevant Codex documentation:

http://codex.wordpress.org/Rewrite_API http://codex.wordpress.org/Rewrite_API/add_rewrite_rule

I'm assuming you don't want to use query strings, since in that case it would be as easy as using this URL:


and getting the value this way:


However, keep in mind that the .../param_name/param_value/ syntax is not the best in terms of semantics and SEO. URLs are supposed to be hierarchical.

Some use /param_name:param_value/ instead, although the most "pure" solution would be to use ?param_name=param_value.


Try this in your init callback:


add_rewrite_tag('%cid%', '([^&]+)');

You can then use the following to get your cid variable value:

global $wp_query;

I used the following functions:
