Duplicate/Copy Order Woocommerce

When PayPal sends an IPN subscr_payment update to WooCommerce I'm using this code inside the valid_paypal_standard_ipn_request action to create new orders from existing orders. Once in a while the shipping info is empty on the new order. I'm not sure what's causing that, but this is new code so it might be buggy.

All the components of a WooCommerce order are here. I created this from the logic in class-cw-checkout.php create_order, but used an existing order to provide the values.

<?phpadd_action( 'valid-paypal-standard-ipn-request', 'sapce_valid_paypal_standard_ipn_request', 10, 1 );function sapce_valid_paypal_standard_ipn_request($formdata){    if (!empty($formdata['txn_type'])) {        if ($formdata['txn_type'] === "subscr_signup") {            $custom = unserialize(stripslashes($formdata['custom']));            $order_id = $custom[0];            $payment_profile_id = $formdata['subscr_id'];            addPayPalPaymentProfileIdToAutoShipOrder($order_id, $payment_profile_id);        }        if ($formdata['txn_type'] === "subscr_payment" && $formdata['payment_status'] === "Completed") {            $paypal_transaction_id = $formdata['txn_id'];            $custom = unserialize(stripslashes($formdata['custom']));            $original_order_id = $custom[0];            createNewOrderAndRecordPayment($formdata);        }        if ($formdata['txn_type'] === "subscr_cancel") {            customerCanceledAutoShipOrderFromPayPal($order_id, $payment_profile_id);        }    }}

<?phpinclude_once ('../../../wp-load.php');include_once ('../../../wp-blog-header.php');function createNewOrderAndRecordPayment($formdata) {    global $wpdb;    global $woocommerce;    $paypal_transaction_id = $formdata['txn_id'];

You can copy all the order meta data first using wc_get_order_item_meta(), like this:

$main_order_metadata = get_metadata( 'post', $main_order_id );

And you can add the copied metadata using add_post_meta()

After that you can copy all item meta keys with wc_get_order_item_meta(), like this:

$order_item_metas = wc_get_order_item_meta( $order_item_id, '' );

And you can add the copied item metas using wc_add_order_item_meta()
