I don't know how feasible coming up with an all-encompassing dataset would be. I suppose that I can use DPILink as a starting point, and add more fields as more processors get written. I wonder if having a class for the response would help at all... The data that each processor sends back is pretty different, and it might help to have a class just for handling mapping those results back to a standard. On the other hand, it might just be bloat. That's why I posted a RFC first. :^) > Ie. > > function isCvvValid() > { > return true; // my processing gateway ignores this so don't barf > } > Yeah, each processor has it's own validate() function already. And we'd have to map from whatever the front-end fieldset is to the back-end anyways, with a _prepare() or similar.
