I have searched left, right and center and believe that this does not exist as a built in option in WordPress; is there any way to, problematically, display (or not) a metabox in a custom post type edit screen depending on the content of a metakey value?

The only idea i have is to display the content of the metakey in a hidden field, retrieving it's value with jQuery and based on its content deleting the div containing the metabox pr not.

The content of the metabox is quite resource intensive so i am looking for another solution.

Of course...

function generic_cb($post) {
  echo 'This is a test of the emergency callback system.';

add_action( 'add_meta_boxes_page', 'conditional_meta_box' );
function conditional_meta_box($post) {
  $meta = get_post_meta($post->ID,'meta_key',true);
  if ('abc' === $meta) {
        'CB Test',

The add_meta_boxes* hooks pass the $post variable, so use it to check the meta key in question and conditionally add the meta box. There is a generic add_meta_boxes hook that always runs, but other add_meta_boxes_CPTSLUG hooks that are limited to particular post types. My example applies only to pages.

If your content is a resource intensive as you say, I'd look into transients.

  • If you use the register_meta_box_cb key when you call register_post_type(), it's just a shortcode for calling 'add_meta_boxes_' . $this->name, as shown on this page. Therefore, that callback also receives the $post argument. Dec 6, 2022 at 18:55
