    Hi,

    I was able to drag some existing fields into a group field. but when I do, I lose the value. When I drag them back them I can see the value is still there. I want to therefore set the new group field value with the old value. I tried to use:

    add_action( 'init', function() {
    $post_id = $postID;
    $field_id = 'the_field_within_the_groups_ID';
    $value = [
        [
           $field_id  => 'Andy',
        ],

    ];
    rwmb_set_meta( $post_id, $field_id, $value );
}, 99 );

    But in this example from your documentation, I do not understand where it needs the group value. Maybe I am getting confused by all the field IDs. Can I clarify what the field_id is? Is this the field ID of the field inside the group, is it the group id or is it the field_id of the entire custom group?

    For my case I have:

    Field Group ID = Research (so this is for all the below custom fields)
$prefix = academic
$IDofTheOriginalFieldIWantToMoveTheValueFrom = $prefix.$year
$GroupFieldID = $prefix.$Reference
$FieldIDInsideTheGroup = $prefix.$year  //It is the same as the original as I dragged it into the group, but the values did not transfer,

    Please let me know how I can fix this so that the value of $FieldIDInsideTheGroup becomes $IDofTheOriginalFieldIWantToMoveTheValueFrom

    And just so you can see where I got up to (might be easier to explain where its going wrong): 

    add_action('init', function() {
    $args = array(
        'post_type' => 'research',
        'order' => 'DESC',
        'nopaging' => true,
    );
    $query = new WP_Query($args);

    if ($query->have_posts()) {
        while ($query->have_posts()) {
            $query->the_post();
            $valueToCopy = rwmb_meta('academicyear', '', $post->ID); // $IDofTheOriginalFieldIWantToMoveTheValueFrom
$year_groups = rwmb_meta('academicreference_group', '', $post->ID) ?? ''; // $GroupFieldID
  
foreach ($year_groups as $year_group) {
$year = $year_group['academicyear'] ?? ''; // $FieldIDInsideTheGroup 
}
rwmb_set_meta($post->ID, $year, $valueToCopy);
;
		}}}, 99);

    Hello,

    This need to have some custom code to move data from a top field to a group field. You can refer to this topic to have a basic knowledge about that https://support.metabox.io/topic/migrating-from-regular-fields-to-a-grouped-field/#post-34319

    If you are not able to complete the task, you can contact us here https://metabox.io/contact/
    our development team will help you with an extra fee.

    Hi Peter,

    Thank you for that! I was able to migrate all text, links etc.

    However, I am really strugling with taxonomies.

    I noticed that when I pulled them into the group, the post was disassociated with the term. I fixed it by reuploading the data into another field outside the group. But I want to pull that data into the group.

    I think I can get the terms, but then it does not work the same way as the text fields. I cannot insert and save.

    Help would be hugely appreciated. Just the functions I can use to do this successfully.

    And in case anyone comes across this thread - this is how I did the text fields:

    add_action('init', 'migratethefields', 99);

function migratethefields() {
    
    $fields = array('year','peer-review', 'doi', 'co_authorYN', 'citation');
    $prefix = 'academic';
    $fieldgroup = 'reference_group';
    $group_field_ID = $prefix . $fieldgroup;

    foreach ($fields as $field) {
        $new = 'justtostoptheinit';
        $field_ID = $prefix . $field;

        if (get_option($new . $field_ID)) {
            continue;
        }

        $args = array(
            'post_type' => 'research',
            'posts_per_page' => -1,
        );
        $query = new WP_Query($args);

        if ($query->have_posts()) {
            while ($query->have_posts()) {
                $query->the_post();
                $post_ID = get_the_ID();

                $valuestotransfer = null;
                $valuestotransfer = rwmb_meta($field_ID, '', $post_ID);

                if (empty($valuestotransfer)) {
                        $valuestotransfer =   rwmb_get_value ($field_ID, '', $post_ID);
                }
				if (is_array($valuestotransfer) && isset($valuestotransfer[0]) && is_object($valuestotransfer[0])) {
    $valuestotransfer = array_map(function($term) {
        return $term->term_id;
    }, $valuestotransfer);
}
                $group_field = rwmb_meta($group_field_ID, '', $post_ID);

                   if (!empty($valuestotransfer) && is_array($group_field) && isset($group_field[0])) {
                        $group_field[0][$field_ID] = $valuestotransfer;
                    }
                  
                    $updated = update_post_meta($post_ID, $group_field_ID, $group_field);
    }
}
