Sessions and passing variables

Go to solution Solved by teamatomic,

I'm creating a questionnaire to try and get better at understanding sessions but I've stupidly fallen at the first hurdle.


My problem is that I can't successfully pass variables from one page to another. You see, I'm trying to split my questionnaire into smaller questions, rather than having really long list of questions.


Here is what the php code in my first page looks like;


$_SESSION['contact_us'] = $contact_us;
$_SESSION['response_time_email'] = $response_time_email;

//checks to see if form is submitted and a question (tick box) has been checked
if(isset($_POST['submitted'])) {
if(!isset($_POST['contact_us'])) {

                //if check box empty display
	$must_complete = "<div id=\"fail\"><p>Please select a contact method; <strong>email, tel, fax or post</strong></p></div> ";

                 //if checked take them to the next page

	//$confirm = 'yes '.$contact_us.'';


the two variables $contact_us and $response_time_email are there to store the variables and then pass them to the next page.


Here is the php code in my second page, that receives it


$contact_us = $_POST['contact_us'];
$response_time_email =  $_POST['response_time_email'];

//if previous button is submitted go to previous page
if(isset($_POST['previous'])) {




I think I could have it all mixed up here. If anyone can point in the right direction I would be grateful.


Many thanks

In your first page you set the session vars, good. In your next page you convert POST to $contact_us. Bad, if you want what was in the session var. On your second page you need to do the reverse of the first page:


instead of using POST, that is just for posted form data.
