Navigating using PHP

[Anon]

I have a questionaire which offers something like twenty different questions which require multiple choice answers. I would like each question on a different page (all comming from a MySQL database).

The problem is how would I record which question I should be looking at as I move to the next question. In essence I want to be able to move to the previous and next and somehow record the current question number so that I know which should be the next question when navigating.

Any help please?

Many Thanks

mmmm maybe u can save the quest index in a session var and increment or decrement as u move

or just put the current question id in the link to the next/previous question:

echo '<a href='bla.php?iQuestionID='.($iCurrentQuestionID-1).'>prev</a>';

echo '<a href='bla.php?iQuestionID='.($iCurrentQuestionID+1).'>next</a>';

How can I ensure that the variable containing the current question id is incremented before moving to the next step or decremented before moving to the previous step?

I obviously need to do this to ensure that the code:

echo '<a href='bla.php?iQuestionID='.($iCurrentQuestionID-1).'>prev</a>';

echo '<a href='bla.php?iQuestionID='.($iCurrentQuestionID+1).'>next</a>';

• works correctly.

Ehm... what's the problem?

You can do it using cookies... just make sure that the variable that you store in a cookie is an array...

An array containing what?
Don't you think it's a little overkill to store a cookie on the client when a simple link with a parameter would suffice?

Hmm...

I thought he was trying to get advice on how to store answers as he is navigating through the pages... That is why I suggested using cookies and storing result of a 20-question survey into an array...

I think that I might've misunderstood his question...
