Think I posted this in the wrong forum before,, so..
Having searched everywhere for a oscommerse contribution or donations modification I decided to do it myself. And very successfully I might add. This was not an easy task and I can see why there does not appear to be one.
To see this modification use this link. Enter any donation amount. Take it all the way to where you would add a credit card. :) make a donation if you’d like. Notes: You can add as many items as you want to the shopping cart and add a donation as well. The modification uses sessions and database calls.
As much as I love and appreciate Open Source Coding, I do not have the time to make this a formal contribution. I code for all the major eCommerce packages. If your interested in applying this to your site. Contact me thru the forums section here.
