form data , not able to go to previous page

[stijn0713]

Hello, i'm trying to make a little survey program.

 

So far, in my view_survey.php page i retrieve all the questions and options from the database and put them in a session. For each new question, i echo a form with question and the options and, after submit i unset that question in the session.

 

I don't think this is a good way, as i cannot go back to the previous question for example.

 

Any suggestions of tackling it another way?

Store the question ID / step number in the session, and use that to fetch the correct question from the database when you need it.

I've answered a very similar question to this one a few weeks back, and outlined how I'd do the process in my reply in that thread. I recommend a search for it, as you should find that thread quite useful.
