Variable Scope

Scenario:

I've got a 4 step checkout. During the 2nd step, I collect order info and set to a model variable Order and store that in a session var called session[:order] to process later or repopulate the form if they do not finish checkout. I do NOT, however want to store the credit card number in the session, yet I still need to carry it over from the 2nd step to the final step.

Question:

What's the best way to carry the CC# over a few steps without storing it in the session and without creating a hidden form input. Class variables? The flash?

Thanks, Chad

Hi Chad,

I think using the flash would be your best option. Just pass it from Step2 to Step3, then to Step4. that should do it.

Cheers, Simon

One problem:

Say they get to the review step and hit refresh a few times, or remove a product, or.... Flash goes bye bye.
