session vars won't change value

Anon

Hi all, this is a re-post.
I think I'm missing somthing fundamental.
Please check out the simple scripts below and tell me why $name will not change values?

thanks

Nick

<?
// ses.php
session_start();
session_register(\"name\");
?>

<body>
<form method=\"post\" action =\"ses2.php\">
input name
<br>
<input type=\"text\" name=\"name\">
<br>
<br>
<input type=\"submit\">
</body>

<?
// ses2.php
session_start();
?>

<?
// ses3.php
session_start();
?>

<body>
<br>
<br>
and the name is <? print($name); ?>
<br>
<br>
<a href=\"ses.php\">start again</a>
</body>

I always get the first name I entered?

Hope someone can point out the error of my ways!

much appriciated

Nick

You mean if you go back to the beginning you still get the last name?

I think session variables are set rather than GET/POST variables, so $name is being overwritten with the session one, and not the new form one.

Try session_destroy() or having something like:

<?
// ses2.php
$newname = $name
session_start();
if ($newname) {
$name = $newname;
}
?>

Hope that helps!
