Passing Form Elements as Session Variables

Jason:

Some time ago you suggested I use the code below to create a Session variable for each form element in a WADA Search Page. You suggested I enter that code on line one of the Results page.

<?php
@session_start();
if($_SERVER["REQUEST_METHOD"] == "POST") {
foreach($_POST as $k => $v) {
// store as session
$_SESSION[$k] = $v;
}
}
?>

Then you suggested I enter the following 2 lines of code on the Update page so that I may retrieve the session variable S_teacherName in that page. That code I entered on line one of the Update page.

<?php @session_start(); echo((isset($_SESSION["S_teacherName"]))?$_SESSION["S_teacherName"]:"") ?>

<?php echo((isset($_SESSION["S_teacherName"]))?$_SESSION["S_teacherName"]:"") ?>

Your suggestions worked well then and I'm sure they would work fine always. However, now I would need to use one of the Session variables in the Results page itself, but when I enter all the code listed above in the Results page, I cannot retrieve any of the new Session Variables in the Results page.

I've also tried not entering the second line of code (<?php @session_star(): echo.....), but it doesn't work either.

What am I not doing right?

Thank you for your attention.

this code:

<?php
@session_start();
if($_SERVER["REQUEST_METHOD"] == "POST") {
foreach($_POST as $k => $v) {
// store as session
$_SESSION[$k] = $v;
}
}
?>


loops through each form element on your page, and creates a session variable of the same name with the value that was entered.

to use those session variables on another page, you need to note the name of the form element, and use that as the session name.

this code:
<?php @session_start(); echo((isset($_SESSION["S_teacherName"]))?$_SESSION["S_teacherName"]:"") ?>

would work if the form element where named "S_teacherName". but if the form element has a different name, you need to change that code accordingly.

Many thanks
