Comment Meta

Comment meta containers add extra fields to the comment edit screens. Field data is stored separately for each comment as comment meta (see add_comment_meta).

use Carbon_Fields\Container;
use Carbon_Fields\Field;

Container::make('comment_meta', 'Comment Information')
        Field::make('text', 'crb_comment_rating', 'Comment Rating'),
        Field::make('text', 'crb_comment_additional_info', 'Additional Comment Information'),

Accessing field values

To access field values you need to use the function carbon_get_comment_meta($comment_id, $name, $type = null), where:

Parameter Description
$comment_id Comment ID where your value was entered.
$name The name of the field to be retrieved.
$type (optional) If the field you want to retrieve is of type complex, you need to pass "complex".
<?php $comments = get_comments(array(
    'post_id' => get_the_ID(),

foreach ( $comments as $comment ) {
    $comment_additional_info = carbon_get_comment_meta($comment->comment_ID, 'crb_comment_additional_info');
    $comment_rating = carbon_get_comment_meta($comment->comment_ID, 'crb_comment_rating');

    if ( !empty($comment_additional_info) ) {
        echo $comment->comment_ID . ' info: '. $comment_additional_info;

    if ( !empty($comment_rating) ) {
        echo 'Rating: ' . $comment_rating;
