    Hello,

    I would like to display the post id in a custom field, so later I can display it as an admin column. Could you please help me on how to do it?

    Thank you!

    Hi Janos,

    You can create a text field, enable show in admin columns, then use the action hook rwmb_{$field_id}_after_save_field to update the field value by post ID. For example:

    add_action( 'rwmb_fieldID_after_save_field', function ( $null, $field, $new, $old, $post_id ) {
    $storage = $field['storage'];
    $storage->update( $post_id, $field['id'], $post_id );
}, 10, 5 );

    Refer to this documentation https://docs.metabox.io/actions/#rwmb_after_save_field

    Thank you, Long!

    So, if my field ID is pro_new_id and the field label is ID, then the code will look like:

    add_action( 'rwmb_pro_new_id_after_save_field', function ( $null, $field, $new, $old, $post_id ) {
    $storage = $field['ID'];
    $storage->update( $post_id, $field['pro_new_id'], $post_id );
}, 10, 5 );

    Is that correct? Does it matter that I made the field Read-Only? Sorry, I barely speak PHP.

    Thank you!

    Hi,

    Just replace fieldID by your field ID pro_new_id

    add_action( 'rwmb_pro_new_id_after_save_field', function ( $null, $field, $new, $old, $post_id ) {
    $storage = $field['storage'];
    $storage->update( $post_id, $field['id'], $post_id );
}, 10, 5 );
