I have a multisite environment where I am switching databases to retrieve data in a custom post type entered on one site to show on the other site.
On the site where the data is not stored (and the post type is not defined), I want a permalink like /post-type-name/item-slug/ to end up at a page named /post-type-name/. I can then write code in the page specific template to switch databases, retrieve the data for item-slug, and show it. But I am not sure how to make the permalink work, other than to do it like /post-type-name?item-slug.

Reset to default 0What you need is to register your own Rewrite Rule. To do it you should use add_rewrite_rule function.
function my_custom_external_rewrite_rule() {
add_rewrite_rule('^post-type-name/([^/]+)/?', 'index.php?page_id=<PAGE_ID>&external_page_name=$matches[1]', 'top');
}
add_action( 'init', 'my_custom_external_rewrite_rule' );
And you'll have to register your custom query variable (using query_vars hook):
function my_custom_external_query_var( $query_vars ) {
$query_vars[] = 'external_page_name';
return $query_vars;
}
add_filter( 'query_vars', 'my_custom_external_query_var' );
This way requests to post-type-name/slug/ will cause displaying page with and you will be able to obtain the slug of external post with get_query_var( 'external_page_name' );
