I followed this great tutorial by Justin Tadlock to add some custom metaboxes to a custom post type. It worked great! I’m trying to take things a step further and pass some additional arguments to the function that is doing the updating. But I’m getting this error when saving the post.
Fatal error: Call to undefined function wp_verify_nonce()
From the tutorial I’m trying to pass additional arguments to the function smashing_save_post_class_meta().
