SESSION question

[weemikey]

Hi all! I was pointed to the SESSION array by AndyB (thanks) to deal with some temp storage but now I have another question. I'm making a contact manager with checkboxes to select email addresses. There will be multiple pages that a user might visit while selecting these addresses. I need to store all of them in a big CSV. So I've created a session and a new variable to store the email addresses. I check to see if the session variable is set and add a comma, then the address. Or if the session variable isn't set I create it and add the email address. However I'm not getting the variable to stick around. I go to the page, select my emails, echo them to the screen and all's well. If I deselect all the addresses and just choose one, ONLY that one email address gets echoed back. If I understand how this is supposed to work, this should just KEEP adding addresses to my list until I reset or kill the session. Am I wrong in this understanding? Does the SESSION only apply to the current php script? Any advice would be great. Here's the code! Thanks a million!

 

// for each element in the array, do something
foreach($emails as $value) {

// if we already have an exportemails, add a comma and the email address
// otherwise just add the email

if(isset($_SESSION['exportemails'])){
		$_SESSION['exportemails'] = $_SESSION['exportemails'].",".$value;
	} else $_SESSION['exportemails'] = $value;
}

make sure you have session_start();  at the very top of the page.
