How can I "do something" after a successful PPE order?

I thought you guys were continuing the discussion on a theoretical basis, but if there's still concern for my application (thank you) I had it working @ post 24 above.

After looking a little more carefully, I think I've settled on NOTIFY_HEADER_END_CHECKOUT_PROCESS

It gives me all the vars I need, it happens after function after_process() is called (which is what the payment modules uses to update the history), and I think it is tight enough to not have to worry about refreshes. I tried refreshing and there was no ill effect that I could see.

Does that sound right?

The notifier you chose (NOTIFY_HEADER_END_CHECKOUT_PROCESS) will do the trick for you:
1) It's at the absolute end of the checkout_process processing, just before the redirect to checkout_success.
2) It's not a page that is "easy" to refresh, since it's never visible in the customer's browser.

Thanks to both of you, your suggestions have helped me to implement something similar on one of my local dev sites.

I was/am.

Mainly to get ideas - whether they be sound, practical, efficient, best for purpose, or whatever. It's all good IMO.

I see as a result of this thread we already have one person (frank8) that has taken the idea(s) to do something on his own site(s) -
Something that may possibly never have eventuated otherwise.

The choice of HEADER_START or HEADER_END (or both) is certainly going to be dependent on what is needed and what data is available for that need, and with all that is currently known, I too would say that you have made the right choice for your purpose. I might even go as far to say that I may have made the wrong choice for the purpose of the ec_commerce module.

As a result of this discussion, Frank, and others that follow, have the benefit that neither you or I had when we started our projects - We've covered three possible notifiers (and a combination of them) that *could* be used for a purpose, and we've revealed the benefits and pitfalls for each, and the one instance that wasn't a good choice for the need (the NOTIFY_CHECKOUT_PROCESS_HANDLE_AFFILIATES).

It has been (and is) a good discussion even though the initial 'problem' has been solved.

Cheers

Agreed Rod. I just wanted to be clear that I wasn't still waiting for help :)
