update_post_meta() whenever custom post type is updated

You’re right to use ‘save_post’ action hook. Try this: <?php add_action(‘save_post’, ‘some_function’); function some_function($post_id) { if(get_post_type($post_id) != “VA_LISTING_PTYPE”) return; $meta_value = get_post_meta( $post_id, ‘featured-cat’, true ); if($meta_value != 1) return; update_post_meta($post_id, ‘website’, ”); update_post_meta($post_id, ‘twitter’, ”); update_post_meta($post_id, ‘facebook’, ”); } if you’re on WordPress 3.7 or higher, you can use it this way: add_action(‘save_post_VA_LISTING_PTYPE’, ‘some_function’); … Read more
