Showing Repeatable Group

Hello,

I am trying to add repeatable fields but I can not get the group to display on the front end. For testing purposes I have added the example from the wiki to my theme but still nothing appears.

The data saves in the backend and I can see see it in the database as well. I have other cmb2 fields that are working correctly so I’m kind of at a loss.

Code I’m using

$group_field_id = $cmb->add_field( array(
    'id'          => 'wiki_test_repeat_group',
    'type'        => 'group',
    'description' => __( 'Generates reusable form entries', 'cmb' ),
    'options'     => array(
        'group_title'   => __( 'Entry {#}', 'cmb' ), // since version 1.1.4, {#} gets replaced by row number
        'add_button'    => __( 'Add Another Entry', 'cmb' ),
        'remove_button' => __( 'Remove Entry', 'cmb' ),
        'sortable'      => true, // beta
        // 'closed'     => true, // true to have the groups closed by default
    ),
) );

// Id's for group's fields only need to be unique for the group. Prefix is not needed.
$cmb->add_group_field( $group_field_id, array(
    'name' => 'Entry Title',
    'id'   => 'title',
    'type' => 'text',
    // 'repeatable' => true, // Repeatable fields are supported w/in repeatable groups (for most types)
) );

$cmb->add_group_field( $group_field_id, array(
    'name' => 'Description',
    'description' => 'Write a short description for this entry',
    'id'   => 'description',
    'type' => 'textarea_small',
) );

$cmb->add_group_field( $group_field_id, array(
    'name' => 'Entry Image',
    'id'   => 'image',
    'type' => 'file',
) );

$cmb->add_group_field( $group_field_id, array(
    'name' => 'Image Caption',
    'id'   => 'image_caption',
    'type' => 'text',
) );

Front end code:

<?php

$entries = get_post_meta( get_the_ID(), 'wiki_test_repeat_group', true );

foreach ( (array) $entries as $key => $entry ) {

    $img = $title = $desc = $caption = '';

    if ( isset( $entry['title'] ) )
        $title = esc_html( $entry['title'] );

    if ( isset( $entry['description'] ) )
        $desc = wpautop( $entry['description'] );

    if ( isset( $entry['image_id'] ) ) {
        $img = wp_get_attachment_image( $entry['image_id'], 'share-pick', null, array(
            'class' => 'thumb',
        ) );
    }
    $caption = isset( $entry['image_caption'] ) ? wpautop( $entry['image_caption'] ) : '';

    // Do something with the data

    echo $title;
    //print_r($entry);
}
?>

I only get blank line also when trying out print_r. Any help or direction would be appreciated.

Thanks
