Here's what we just implemented. This is with 4.0.14. Our conditions are payment method "Checks/Money Orders" and non-Wholesale customers.

1. Pass the paymentid by changing cart.php around line 587 from:
Code:
# # Calculate all prices # $cart = func_array_merge ($cart, func_calculate($cart, $products, $login, $current_area));
to:
Code:
# # Calculate all prices # $cart = func_array_merge ($cart, func_calculate($cart, $products, $login, $current_area, $paymentid));

2. Accept the paymentid by changing include/func.php around line 1007 from:
Code:
function func_calculate($cart, $products, $login, $login_type) {
to:
Code:
function func_calculate($cart, $products, $login, $login_type, $paymentid="") {

3. In the same file and function, pass the paymentid again by changing the following around line 1019:
Code:
$result = func_calculate_single ($cart, $products, $login, $login_type);
to:
Code:
$result = func_calculate_single ($cart, $products, $login, $login_type, "", $paymentid);
and around line 1034 from:
Code:
$result = func_calculate_single ($cart, $_products, $login, $login_type, $provider_for);
to:
Code:
$result = func_calculate_single ($cart, $_products, $login, $login_type, $provider_for, $paymentid);
and around line 1074 from:
Code:
$result = func_calculate_single ($cart, $_products, $login, $login_type);
to:
Code:
$result = func_calculate_single ($cart, $_products, $login, $login_type, "", $paymentid);
These last two changes may not be necessary.

4. In the same file, adjust function func_calculate_single to accept the paymentid by changing:
Code:
function func_calculate_single($cart, $products, $login, $login_type, $provider_for="") {
to:
Code:
function func_calculate_single($cart, $products, $login, $login_type, $provider_for="", $paymentid) {

5. In the same file and function, add the following towards the end of the function:
Code:
if ( ($customer_info[membership] != "Wholesale") && ($paymentid == 5) ) { $discounted_subtotal -= ($subtotal * .05); $display_discounted_subtotal = $discounted_subtotal; }
just above:
Code:
# # Calculate Gift Certificates cost (purchased giftcerts) #
Your paymentid may be different as well as the exact membership name.

6. Adjust skin1/customer/main/cart_totals.tpl by adding the following after the if block for "if $cart.discount gt 0":
Code:
{if ( ($userinfo.membership ne "Wholesale") and ($smarty.get.paymentid eq 5) )} {math equation="x*.05" assign="payment_discount" x=$cart.subtotal} <tr> <td nowrap><font class="FormButton">Payment Discount:</font></td> <td>[img]{$ImagesDir}/null.gif[/img]</td> <td nowrap align="right"><font class="ProductPriceSmall">{include file="currency.tpl" value=$payment_discount}</font></td> <td nowrap align="right">{include file="customer/main/alter_currency_value.tpl" alter_currency_value=$payment_discount}</td> </tr> {/if}


To also display this information in the order history and invoice:

7. Add the following to function func_order_data in include/func.php towards the bottom just above the return:
Code:
if ( ($order[membership] != "Wholesale") && ($order[payment_method] == "Checks/Money Orders") ) { $order[discounted_subtotal] -= ($order[subtotal] * .05); $order[display_discounted_subtotal] = $order[discounted_subtotal]; }

8. Add the following to skin1/mail/html/order_data.tpl after the if block for "if $order.discount gt 0":
Code:
{if ( ($order.membership ne "Wholesale") and ($order.payment_method eq "Checks/Money Orders") )} {math equation="x*.05" assign="payment_discount" x=$order.subtotal} <tr> <td align="right" height="20">Payment Discount:</TD> <td align="right">{include file="currency.tpl" value=$payment_discount}</td> </tr> {/if}
Your exact payment method name may be different.

If anyone has any improvements to this, please post.
