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_close();
header('Location: http://www.mysite.com/test/testsess2.php');
exit();
}
?>

<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.dtd";>
<html xmlns="http://www.w3.org/1999/xhtml";>

<title>Untitled Document</title>

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

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

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('Location: ....')." 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? 

Before the header("location: "), call session_write_close().

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"].$url;
 session_write_close();
 header("Location: ".$url);
 exit();
}

or just use that one :-P



TIA,

Larry,

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

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? :-)
