How to show a preview / confirmation page before writing the form to the database

[eluser]JeremyApp[/eluser]
Someone correct me if this is a bad way to do it, but I generally use flashdata for this purpose.

Flashdata is a part of the CI session library that stores temporary variables, usually for the next request only (optionally the next two requests). I will usually write the inputted data to flashdata and then display it on the next page. Since it should be valid for another request, I can either choose to write it to the database or discard.
