ParticipantI have a field group (ptm_elements) with subfields (not clonable).
The function stops because $group = empty but it isn't. What is wrong?
function showElement($type) {
$group = rwmb_meta( 'ptm_elements');
if ( empty( $group ) ) {
return '';
}
$output = '';
$output = $group[$type] ?? '';
return $output;

ModeratorHi Cees,
You can try to pass the post ID to the helper function
rwmb_meta()like thisfunction showElement($type, $post_id) { $group = rwmb_meta( 'ptm_elements', '', $post_id); ... }Refer to the documentation https://docs.metabox.io/rwmb-meta/
December 2, 2021 at 6:54 PM #32363ParticipantHi Long,
I don't understand which post_id U have to use.
The function is placed on an element of a page (in Oxygen) and decide of it is hide or not.
December 3, 2021 at 12:46 PM #32387ModeratorHi,
When you call the custom function and pass the
typeto the group, you need to pass the post ID also. For exampleshowElement( 'my-type', 12345 )Or you can contact Oxygen support to get the post ID and pass it to the helper function
rwmb_meta().December 3, 2021 at 2:53 PM #32390ParticipantPlease for me: why I the post-id not in the documentation here:
https://docs.metabox.io/extensions/meta-box-group/Sometimes it cost me a lot of time to figure out how it works.
December 4, 2021 at 10:45 PM #32421ModeratorHi Cees,
The post ID is written down in the helper function
rwmb_meta()documentation as I posted above.
