Keeping lots of data from one request to the next -- is flashdata usable for this?

[eluser]parham90[/eluser]
Hello,

As said earlier in another thread, I am working on a sign up wizard. Previously, in the second step, the meta data (E.G. first name, last name, etc) were received from the user and added to the database. However, since step two is not the last step and step three actually is, I want the adding of data to not be done until the third step, too, is completed. So, what I need to do is to keep the values entered by the user in the second step, combine it with the data given in the third step, and then add them all together. Now, the question is, how can I do that? Should I use flashdata and keep using keep_flashdata (or whatever the name is; will look it up in the guide if the answer is "Yes").

Thanks!
