[RESOLVED] Session variables from page to page

rfusca

I know session variables seem to be one of those things that pop up alot in newbie posts, but I've tried everything I can think of to get this to work and it just doesn't. When I set a session variable and try to access it the next page, it just doesn't show.
I know it maybe something simple but its driving me up the wall.

I'm using windows, apache 2.2.3 and php 5.2.0.

You can check my phpinfo() here if you want.

This is the only code on both pages, just to test. That is trial1.php followed by trail2.php


<?php
session_start();
$_SESSION['var1'] = true;
session_write_close();
header('Location: trial2.php');
exit;
?>



<?php
session_start();
echo $_SESSION['var1'];
exit;
?>

Thanks,
Chris

Change this

session_start();
$_SESSION['var1'] = true;
session_write_close();
header('Location: trial2.php');
exit;

to this (lose the session_write_close())

session_start();
$_SESSION['var1'] = true;
header('Location: trial2.php');
exit;

Is doesn't work that way either, I originally had it like that, but some posts online suggested the close.

Hey

There are a couple of things you can try just to get a handle on whats happening

Change trial1.php to be something like

session_start();

$_SESSION['test1'] = 'testing 123 new value';

print '<br>';

print session_id() . '<br>';

print '<a href="trail2.php">link</a>';

change trial2.php to something like

session_start();

print $_SESSION['test1'] ;

print '<br>';

print session_id() . '<br>';

the session_id on both should be the same, if its not then you may have a problem storing your id in a cookie.

you could always change the link in trial1.php to

print '<a href="trail2.php?id=' . session_id() . '">'

in trial2.php add a line before session_start() to say

 session_id($_GET['id']);

this should then tell the session_start command to use that session id

Hope this helps

When rewritting the code as suggested, the session IDs are the same. And the variable still doesn't print.
Try it here at http://rfusca.dyndns.org/trial1.php.

Another thing to try is:

place print_r($_SESSION); on the pages. This will show you exactly what it store4d in the session.

Note that 'true' will echo as 1 and not true!

rfusca

I realized that true would echo as 1.
This is printed on the first page.

Array ( [test1] => testing 123 new value )

and then just

Array ()

on the second.

Hm.. Could it be that the session safe path doesn't exist or is non-writable (Clutching at fragments of ideas here).

In php.ini check for session.save_path. See whether it exists and is writeable.
What level error reporting are you using? (If the path is not writable, it should show up in the erros / warnings).

timus

another thing to try is add the following to the top of trail1.php

ini_set(session.auto_start ,1);

You may have to check the syntax and this is really clutching at straws now

Hope this helps

Sweet! It worked, my session save path was pointing somewhere off in oblivion, I
changed it to a valid location and away we go.
Thanks!
