Calculated custom field question

    Hello,

    I need to create a custom field that substracts an existing custom field from an existing order total field. How would I achieve that?

    The result would be :

    [custom_field] = [order_subtotal_minus_discount] – [ecopart]

    I tried using a calculated order field, but sadly it did not work.

    Thanks a lot for the help.

    I did not get very far using PHP since I’m a novice, but, to start, I tried getting the order total and it threw me an error:

    add_filter('woe_get_order_value_order_subtotal_minus_discount_and_ecotax',function ($value, $order, $fieldname) {
    $value = $order->get_line_subtotal();
    return $value;
    },10,3);

    That’s why I was wondering if it was possible to substract one field from another? It would be much simpler this way, since the fields already exists on the order export.

    $order is https://woocommerce.github.io/code-reference/classes/WC-Order.html

    so you should use

    add_filter('woe_get_order_value_order_subtotal_minus_discount_and_ecotax',function ($value, $order, $fieldname) {
    $value = $order->get_subtotal() - $order->get_discount_total() - $order->get_meta("ecopart");
    return $value;
    },10,3);
