Working with sessions and input type=file in a multi-page form
I need to make a multi-page form. One of the pages will have "input type=file" elements.
1. Is it possible to save these values in session variables for posting? Will the actual file upload somehow be done when I finally submit the whole form?
2. Regarding posting generally: How do I post session variables at the end of the process of the user filling in all the pages? Do I make a dummy form with hidden variables for all the variables previously saved as session variables?
