cross page error messages

[pberce]

Prior to using Prestashop I was using osCommerce. One of the things I liked about osCommerce was the ability to send messages between pages. What I mean by this is, for example, if the customer changed their account information, when finished with updating the database I would redirect them back to their "account" page from the "account edit" page and also add a "Successful in updating information" message to a message object that would then be displayed on that page once the redirect occurred.

 

I don't see anything like this in Prestashop. What I find I have to do is to append a GET to the redirect URL and then handle this on the next page.

 

A good example of this is credit card charges. I'm implimenting my credit card charge process from my own version of authorize.net payment module. If the payment is successful I want to redirect them to the order history page and then display a "Your order was successfully charged" message. How would you recommend doing this? Is using GET the only option?
