Forms, Session and Header

[tempi]

Hi there,

 

Is it possible, that a redirect with header("location:X") destroys the postvars?

 

I have site 1.php with a form field:

 

<input name="firstname" type="text" value="<?=$_SESSION['firstname']?>">

 

Now I post that Field on 2.php where I want to save it in the session and redirect back:

 

$_SESSION['firstname'] = $_POST['firstname'];
header ("Location: 1.php?".session_name()."=".session_id());

 

The Sessionvar "firstname" isn't set on the 1.php now - why?

 

I read, that header-redirects loses the session ID so I put them in the URL. Still kinda doesn't work.

 

Any suggestions?

 

Thanks

I've used redirect via header() and never had a session ID destroyed...!?

Well I think the problem is, that the postvars aren't posted correctly because of the redirect. So they won't be saved in the sessionvar.

 

So finally it's maybe not a session-problem but a post-problem?!

 

Did anyone experience something like that?

If you use header() to redirect a user to a new page then yes, the POST vars will be lost. Either pass the data in the URL or look at handling the data differently.

 

$_GET: Get the variables from the URL

$_POST: Get the variables from a form

$_REQUEST: Use either above method but I'm not sure which takes precedence if you have POST and GET with the same name.

But if I save my Postvar into the sessionvar before I redirect with header() - why is it still lost?

Be sure to add session_start() at the start of each script.

yeah I certainly did that.

Am I totally wrong?
