Issues with PHP sessions

[ryanhellyer]

I read the other topic on here recently about PHP sessions. So I decided to have a crack at setting them up myself for a small project I'm working on. However I'm having trouble with my code

The following code does exactly what I want it to, but I need to click submit twice for the effects to be shown.

PHP Code:

<?php session_start(); ?>

<form method="post" action="example2.php">
    <input type="text" name="bla" value="<?php echo $bla; ?>" />
    <input type="hidden" name="action" value="update" />
    <input type="submit" name="Submit" /></p>
</form>

<h1><?php echo $bla; ?></h1>

<?php
    foreach ($_POST as $key=>$value)
    {$_SESSION[$key] = $value;}
?>

Do any of you know what I'm doing wrong?

Your session data doesnt exist untill after the form is done.

Move the following code to the top of your page, just below session_start().

PHP Code:

<?php
    foreach ($_POST as $key=>$value)
    {$_SESSION[$key] = $value;}
?>

That did the trick!
