hello daniweb members
i have added custom post type in Wordpress that works like slideshow,
all slides are clickable and open in products slug.
how can i query posts subcategories that match with the slide clicked?

code for custom post type is this

add_action( 'init', 'products_post_type' );
function products_post_type() {
  register_post_type( 'products',
    array(
      'labels' => array(
        'name' => 'Products',
        'singular_name' => 'Products'
      ),
      'public' => true,
      'has_archive' => true,
      'supports' => array( 'title', 'editor', 'excerpt', 'thumbnail' )
    )
  );
}
