Participanti can remove the fields from the group, and they work. I can see the fields encoded in post meta in the DB. Spent too much time on it so I'm ditching the groups, but still wondering why...
Code for the Custom fields
<?php add_filter( 'rwmb_meta_boxes', 'gm_meal_plan_recipes' ); function gm_meal_plan_recipes( $meta_boxes ) { $prefix = ''; $meta_boxes[] = [ 'post_types' => ['gb-meal-plan'], 'style' => 'seamless', 'title' => __( 'GBMP Recipe Picker', 'bootscore' ), 'id' => 'gbmp-recipe-picker', 'validation' => [ 'rules' => [ $prefix . 'single_mon_image' => [ 'required' => true, ], ], ], 'tabs' => [ 'tab_mon' => 'Monday', 'tab_tue' => 'Tuesday', 'tab_wed' => 'Wednesday', 'tab_thur' => 'Thursday', 'tab_fri' => 'Friday', 'tab_sat' => 'Saturday', 'tab_collection' => 'Collection', ], 'fields' => [ [ 'type' => 'post', 'id' => $prefix .

ModeratorHello Sean,
Thanks for reaching out.
I'm checking the issue and I will get back to you as soon as I have more information.
January 24, 2026 at 2:36 PM #49667ModeratorHello Sean,
I check the code that you created to output field value in the frontend, and there are some basic issues:
1.
$group_id = "gbr_' . $abbr . '_group";wrong single quotes to get the group field ID. It should be
$group_id = "gbr_" . $abbr . "_group";2.
$img_type = $group[ $field_name ] ?? ''; $image_id = $group[ 'single_mon_image' ] ?? 0;you get the group value with this code
$group_value = rwmb_meta( $group_id, [ 'object_type' => '' ] );but get the subfield value from
$groupvariable. It should be$img_type = $group_value[ $field_name ] ?? ''; $image_id = $group_value[ 'single_mon_image' ] ?? 0;I hope that makes sense.
January 24, 2026 at 2:43 PM #49668ParticipantYes, it makes sense. Targeting the group first had crossed my mind, but I wasn't connecting what
$group_value = rwmb_meta( $group_id, [ 'object_type' => '' ] );was doing... I had it there, I obviously had the variables named incorrectly. I just didn't put two and two together.I'll keep it in mind for next time.
I can see how group can be useful, and I do know you can set a group to store variables however you want. That said, it would be nice if there was a layout option that behaved like a div that only dealt with layout in the editor and you didn't need to think about dimension when calling the custom fields.
Thank you for taking the time to figure out what I did wrong.
