[Done v1.5.5] Payment Methods: Sort Orders 0 and less not honored

I've got a store that has three payment methods:

1. Direct Bank Deposit, sort order 50, no zone restrictions
2. Check/Money Order, sort order 80, zone restriction, disabled
3. PayPal Express Checkout, sort order 0, no zone restrictions
   When the payment methods are displayed on the checkout_payment page, Direct Bank Deposit is listed *before *PPEC. If I change the sort order for PPEC to 1, then it properly displays first. If the sort-order for PPEC is 0 or negative, it is improperly shown after the Direct Bank Deposit method.

When you use a Sort Order greater than 0 on any of the Payment Modules you need a Sort Order on ALL of the Payment Modules that are greater than 0 ... see if that gets them lined up right ...

Ajeh, if I set the sort-order for PPEC to 1 then it properly sorts as the first payment module in the list.

Are you saying that the special handling of a payment module's sort-order, when set to 0, is WAD (working as designed)?

Because an array is built, if you do not have a Sort Order on 1 Payment Module when 1 or more does have a Sort Order > 0 then what happens will be:

1 Display orders can be goobered up

2 One Module could overwrite another module as it will be replaced in the Array

So the rule is, when using any of the Modules:
Payment
Shipping
Order Totals

if 1+ module(s) is given a Sort Order > 0 then ALL need to have their own Sort Order > 0 and it must be unique ...

I told you already!!

@Ajeh, it seems like the processing in each of the admin-level ***Modules ***should do a little detective work and, at a minimum, display a warning to the admin user if "the rule" is violated.

@torvista: You did, but I apparently said it better!:P

There actually is a warning on at least v154, I did not test all versions, but it only shows when there is an obvious conflict on the modules ...

We will try to look into it further to see if that can be changed to if 1 module has a Sort Order but the others do not the warning will still show ... :lookaroun

Fixed in v155. https://github.com/zencart/zencart/pull/703
