Payment type discount.

I had this installed fine and it was working no problem, then today when i go to checkout at step 3

Fatal error: Cannot use object of type queryFactoryResult as array in /home/freerang/public_html/shop/includes/modules/order_total/ot_payment.php on line 97

I had installed the Mod hole version, and it worked great before I added other stuff. I have removed the gift voucher option, but this doesn't cure it.

this is the code that line

if (ereg('^GIFT', addslashes($gv_result['products_model']))) {

Thanks I really need a discount option at checkout for Zen Cart 1.2.7.

Got this answered by Langer if anyone needs it:

change the line to read.

if (ereg('^GIFT', addslashes($gv_result->fields['products_model']))) {

Thanks

I've seen references to the Payment Type Discount module but can't seem to find it. There was a link to it in another thread but I get a 404 error.

Can someone point me in the right direction?

Also wondering if I can apply this discount to a specific credit card? (ie. Amex users get a dicount on purchases).

Cheers!

Its in the archived downloads,

and no it works with a payment type not with a certain card

Thanks! I can't find the archived downloads, can you please point me in the right direction?

... So, that module won't do it but can anyone think of another approach that would allow for a discount on a specific credit card or does it sound totally impossible?

This module is using a percentage discount or fee.
Is there a way to change from a percentage to a flat (absolute) discount or fee?

does this work with 1.38a?

Hi,
For anyone who is interested, I got the Payment Type Discount working with 1.3.8a with the following code.

Replace entire code from /includes/modules/order_total/ot_payment.php
with:

Code:
