I have a multi-page form.
I’d like to have a “prev” and “next” button on page 2, 3 and 4 so that if an user in the middle of filling out page 2 can decide to return to page 1 to edit/enter something and be able to still see values on page 2 where he left off.
Is this possible? any pointers/links would be immensely helpful.
(Yes, I have sessions and I can see the sessions after printr but if Im in the middle of page 2 and click backwards, I still dont see these sessions).
Thanks in advance.
Start the session when the user hits page 1. Each page should look in the session to see if there’s any data there for that page, and if so, render the form with those values pre-filled. When the user hits either PREV or NEXT, process the form as if they hit submit, but instead of saving the values to (for example) a database, save them to the session. Then redirect to the requested NEXT/PREV page. When the user hits DONE (or whatever) on the last page, pull all the values from the session and process them to your database (or whatever.)
