我有下面的代码，可以在预定的活动后更改常规帖子的一个类别。它工作得很好。然而，我需要它来定位WooCommerce产品类别。我的问题：有没有办法调整我当前的代码以适应自定义的帖子类型？

// runs when a post is published
add_action( \'publish_post\', \'wcsri_schedule_post_check\' );

function wcsri_schedule_post_check( $post_id ) {

// set the time when the event should be scheduled
$timestamp = strtotime( \'+7 days\' );

// Schedule the event
wp_schedule_single_event( $timestamp, \'wcsri_check_post\', array( $post_id ) 
);    
}

// a custom hook to schedule
add_action( \'wcsri_check_post\', \'wcsri_check_post_cats\', 10, 1 );

// replace post categories
function wcsri_check_post_cats( $post_id ) {

//categories
$old_cat = get_the_terms($post->ID, "foo");
$new_cat = get_the_terms($post->ID, "bar");

// check for the old category
if ( has_category( $old_cat, $post_id ) ) {
    // update post with new category
    $args = array(
        \'ID\'            => $post_id,
        \'post_category\' => array( $new_cat ),
    );
    wp_update_post($args);
}
}
