[PHP] Session or hidden fields?

[timp]

Hey guys,
I suppose i have a rather simple question, but i am not able to answer it myself, yet. This is the scenario:

You collect user input within a form. The page/script the form is directed at (the form's action) should not process the input, but store it for the next script to process. So there is one script and html page between collecting and processing the data. What is the better way to störe the input. Should i write it to the Session or store it in hidden input fields on the html page in between or is there a better way i did not even see yet?

Thanks for your replies!

Session may be a tad more secure but in the example you describe, for most purposes I very little difference between the two.

Hidden fields can be viewed on the source code of the page containing the input (may not be true if it is all in php). Session data can not be viewed.

sessions would do, save the data every time the form is submitted then use the data when the final process will be done..

if you're into HTML5, you can use Local Storage feature of HTML5 to save data and on the final form retrieve the said data..
