Aren't session variable preserved using "Header('Location: xxx')"?

Jan 18 '06, 01:05 PM

I am trying to pass some info to another page on my site. I set
"session_start( )" in page 1, assign a session variable to a value, then
execute a "header('Locati on: ....')." But on the target page I don't get
any session variable values! BTW, I used a relative location in the
Location header, not an absolute URL. The behavior looks like it started
another session, but it should not have.

Ideas?

TIA,

Larry Woods

Before the header("locatio n: "), call session_write_c lose().

That gave me some serious headaches with mac-based browsers hanging.
Terrible stuff :)

Oh, and you should always use absolute URLs with location. Relative ones do
work, but that's not guaranteed. You could make a function like this to
take care of that for you:

function bounce($url) {
if (sustr($url, 0, 1)=="/") $url="http://".$_SERVER["HTTP_HOST"].$url;
session_write_c lose();
header("Locatio n: ".$url);
exit();
}

or just use that one :-P

Re: Aren't session variable preserved using "Header('L ocation: xxx')"?

Thanks, but I still can't get it to work. Check the following:

Originating Page:

<?
if($_POST['repost']=='y') {
session_start() ;
$_SESSION['xxx']='test';
session_write_c lose();
header('Locatio n: http://www.mysite.com/test/testsess2.php') ;
exit();
}
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dt d">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitl ed Document</title>
</head>
<body>
<form action=<? echo $_SERVER['PHP_SELF']; ?> method="post">
<input type="submit" name="submit" value="Submit" />
<input type="hidden" name="repost" value="y" />
</form>
</body>
</html>

Target Page - testsess2.php:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dt d">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitl ed Document</title>
</head>

<body>
<?
echo "xxx=".$_SESSIO N['xxx'];
?>
</body>
</html>

Try these pages and see if they work for you....

It looks like you're not starting your session in this script:

You need a session_start() right here!

You have to do a "start_session( )" in EVERY script where you use SESSION
variables? I thought that you only had to start the session once.

Larry,

You need to call session_start() at the beginning of EVERY page which
needs session support.

Nope, you need it in every page.

Also, I mistyped - it's session_start() .

And please don't top post.

Not really. You call session_start() on those pages which require
session support, and don't on those which don't need sessions. Saves a
little unnecessary processing time.

Maybe session_connect () might be a better name? :-)

You have to do that every time you want to use the session.

Not to mention the default session handler will only allow two scripts to
use the same session at the same time - if sessions were "always on", then
you'd get timeouts all over the place.

Re: Aren't session variable preserved using "Header('L ocation: xxx')"?

First, I really enjoy working with PHP so I don't want to get something
started, but I also work with ASP and there is no such thing as "turning on
and off" session support. It's just there! The only problem that you run
into is if someone has cookies turned off...but I live with that.

Anyway, I'll remember to put "session_start( )" at the top of each page...and
before any headers...which I also discovered the hard way.

Thanks to all...

Larry
