Enregistrement des champs répétables de metabox

C’est un code que j’adapte https://Gist.github.com/2057532 . Le problème est que je ne parviens pas à enregistrer le contenu des nouveaux champs que j'ai créés. J'avais vérifié les autres questions ici, mais aucune ne m'a aidé. Toute idée où est le problème?

add_action('admin_init', 'slider_metabox_caption', 1);
function slider_metabox_caption() {
add_meta_box( 'repeatable-fields', 'Captions', 'repeatable_metabox_display', 'slide', 'normal', 'high'); }

function repeatable_metabox_display() {
global $post;

$repeatable_fields = get_post_meta($post->ID, 'repeatable_fields', true);
wp_nonce_field( 'repeatable_meta_box_nonce', 'repeatable_meta_box_nonce' ); ?>

<script type="text/javascript">
    jQuery(document).ready(function($) {
        $('.metabox_submit').click(function(e) {
            e.preventDefault();
            $('#publish').click();
        });
        $('#add-row').on('click', function() {
            var row = $('.empty-row.screen-reader-text').clone(true);
            row.removeClass('empty-row screen-reader-text');
            row.insertBefore('#repeatable-fieldset-one tbody>tr:last');
            return false;
        });
        $('.remove-row').on('click', function() {
            $(this).parents('tr').remove();
            return false;
        });

        $('#repeatable-fieldset-one tbody').sortable({
            opacity: 0.6,
            revert: true,
            cursor: 'move',
            handle: '.sort'
        });
    });
</script>

L'utilisation du code suivant vous permet de récupérer le tableau.

foreach ($repeatable_fields as $v) {

}

Ensuite, vous pouvez accéder à des valeurs individuelles avec quelque chose comme ceci:

<?php echo $v['text']; ?>

Peut-être que vous le sauvegardez mal, changez ceci:

if ( !empty( $new ) && $new != $old )
    update_post_meta( $post_id, 'repeatable_fields[$i]', $new );
elseif ( empty($new) && $old )
    delete_post_meta( $post_id, 'repeatable_fields[$i]', $old );

pour ça:

if ( !empty( $new ) && $new != $old )
    update_post_meta( $post_id, 'repeatable_fields', $new );
elseif ( empty($new) && $old )
    delete_post_meta( $post_id, 'repeatable_fields', $old );
