I have a store selling fresh produce and quite often have products purchased and paid for that aren't available on the day from the market. I then refund the customer (using the woocommerce manual refund facility) and apply the refund total as a credit on the next order. I am displaying a list of all items refunded from the customers previous order and applying the total refund as a discount (negative cart fee) at checkout. Its working perfectly thanks to code from this answer and here
What I would like though is to override the woocommerce procedure of reducing the refunded order total. In my case I am getting a double discount - i.e the initial order that had a refund is being discounted and the subsequent order is also being discounted by the refunded amount.
What I would like to achieve is to stop woocommerce from changing the order total on a refund i.e keep it the same as what the customer paid. Is this possible?
Here is my code so far:
//Check total of refunded items from last order - add as a fee at checkout
function add_last_order_refund_total_at_checkout($cart_object){
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
$user_id = get_current_user_id(); // The current user ID
$customer = new WC_Customer( $user_id );
$last_order = $customer->get_last_order();
$order_id = $last_order;
// Get the WC_Order Object instance (from the order ID)
$order = wc_get_order( $order_id );
// Get the Order refunds (array of refunds)
$order_refunds = $order->get_refunds();
$total_to_refund = $order->get_total_refunded()*(-1);//WIP need to check which items have tax
if (!empty($order_refunds)) WC()->cart->add_fee( 'Refund', $total_to_refund );
}
add_action( 'woocommerce_cart_calculate_fees', 'add_last_order_refund_total_at_checkout', 10, 1 );
//----------------------------------------------------------------
//get list of refunded items from last order - display in a table at checkout
function the_refunded_tems(){
$user_id = get_current_user_id(); // The current user ID
$customer = new WC_Customer( $user_id );
$last_order = $customer->get_last_order();
$order_id = $last_order;
// Get the WC_Order Object instance (from the order ID)
$order = wc_get_order( $order_id );
// Get the Order refunds (array of refunds)
$order_refunds = $order->get_refunds();
if ($order_refunds){
?>
<div class="refund-checkout-table">
<h4>Refunds from previous order:</h4>

<?php
