Displaying Grouped Data on Frontend

Hey Ben,

This sample code registers a group of fields: contact name, contact email, contact phone number:

add_filter( 'rwmb_meta_boxes', 'prefix_register_contacts' );
function prefix_register_contacts( $meta_boxes ) {
    $meta_boxes[] = array(
        'title' => __( 'Contacts', 'textdomain' ),
        'post_types' => 'post',
        'fields' => array(
            array(
                'id' => 'contacts',
                'type' => 'group',
                'clone' => true,
                'fields' => array(
                    array(
                        'id' => 'name',
                        'type' => 'text',
                        'name' => __( 'Name', 'textdomain' ),
                    ),
                    array(
                        'id' => 'email',
                        'type' => 'text',
                        'name' => __( 'Email', 'textdomain' ),
                    ),
                    array(
                        'id' => 'phone',
                        'type' => 'text',
                        'name' => __( 'Phone', 'textdomain' ),
                    ),
                ),
            ),
        ),
    );
    return $meta_boxes;
}

In the single.php, you can add the following code to display contacts:

$contacts = rwmb_meta( 'contacts' );
if ( ! empty( $contacts ) ) {
    foreach ( $contacts as $contact ) {
        echo '<div class="contact">';
        echo '<h4>', __( 'Contact info', 'textdomain' ), '</h4>';
        echo '<p><label>', __( 'Name:', 'textdomain' ), '<label> ', $contact['name'], '</p>';
        echo '<p><label>', __( 'Email:', 'textdomain' ), '<label> ', $contact['email'], '</p>';
        echo '<p><label>', __( 'Phone number:', 'textdomain' ), '<label> ', $contact['phone'], '</p>';
        echo '</div>';
    }
}
