Very similar to this previous question: Changing 'rewrite' argument after custom post type is registered
I am trying to make MarketPress Products hierarchical - I can do it with hacking the plugin files, but I would like to stay away from them if I can.
Is it possible to change arguments of a custom post type after it has been registered, but before all the internal rewrite stuff has been done?
UPDATE: Here's the solution
And as it usually happens, I find the answer a few minutes after posting the question...
So here's what I did in my theme's functions.php file to solve my problem:
function modify_products() {
if ( post_type_exists( 'product' ) ) {
/* Give products hierarchy (for house plans) */
global $wp_post_types, $wp_rewrite;
$wp_post_types['product']->hierarchical = true;
$args = $wp_post_types['product'];
$wp_rewrite->add_rewrite_tag("%product%", '(.+?)', $args->query_var ? "{$args->query_var}=" : "post_type=product&name=");
add_post_type_support('product','page-attributes');
}
}
add_action( 'init', 'modify_products', 1 );
Everything works: hierarchy, rewriting, etc :)
