accessing custom fields with PHP

First of all, This is a great little plugin….! Thank you.

I have created two custom fields labelled wc_order_field_1055 and wc_order_field_3174. The fields work. I can see the data in the subsequent sales order details that are e-mailed.

I also need to pipe these fields into MailChimp. I am using “WooCommerce MailChimp” by SaintSystems for this.

I have some custom PHP:

/************ MAILCHIMP INTEGRATION HOOKS *********/
/*** this code is used by WooCommerce MailChimp by 
     Saint Systems to map custom fields to MailChimp. ***/

/* Shortcodes are... */
add_filter( 'ss_wc_mailchimp_subscribe_merge_tags', 'woocommerce_mailchimp_extra_data', 10, 3 );

/*function for mapping is... */
function woocommerce_mailchimp_extra_data( $merge_tags, $order_id, $email ) {

    // Lets grab the order
    $order = new WC_Order( $order_id );
    $parentOrCh = $order->wc_order_field_1055;
    $source = $order->wc_order_field_3174;
    $zipCode = $order->billing_postcode;

    $new_merge_tags = array(
        'PARENTORCH' => $parentOrCh,
        'SOURCE' => $source,
        'ZIPCODE' => $zipCode
    );

    // combine the two arrays
    $merge_tags = array_merge( $merge_tags, $new_merge_tags );

    return $merge_tags;
}

Here’s my problem, the code transfers the zipcode, but not the two other fields. I suspect I am not accessing the two custom fields properly. Note these two fields are defined in the Order Fields section.

Question: how can I reference the two custom fields please? Thank you, kkc.
