Hi,
How do I call the onAfterOrderConfirm(&$order,&$methods,$method_id) function from within a shipping function?

Is there something that must be done first? I am getting a 500 error everytime I include it as a method in my class.
Basically, I want to send some information about the order to the database after it is completed.

Thanks!

Joel

I found the issue. I had the function onAfterOrderConfirm defined previously in my class.
I guess it got lost in all my functions there.
Its working fine again
thanks!
