[ygennew]

I have some trouble. Try get in cart custom field:

$ds=','.get_custom_field('ynamicalprice:formatted_list', ', ').',';

and $ds is empty.
How can i get this field information?

I use this code in cart.php:

/**
 * Cart Page
 *
 * @author      WooThemes
 * @package     WooCommerce/Templates
 * @version     2.1.0
 */

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

global $woocommerce,$product,$order,$post;

wc_print_notices();

do_action( 'woocommerce_before_cart' ); ?>

<form action="<?php echo esc_url( WC()->cart->get_cart_url() ); ?>" method="post">

<?php do_action( 'woocommerce_before_cart_table' ); ?>
