refresh page

Hi all,
I need to make a session last until the browser is closed. The browser can be left open all day. So i thought the best way would be to refresh the page every 20 mins with a
Code: Select all
<meta http-equiv="refresh" content="0; url=home.php">
However i cant simply do this because i pass many variables on this page, which are either posted via a form or sent via a <href> link and i have many variables passed from popups back to this home.php page, so coding for each variable would be crazy.
The question is how can i display what variables are currently passed through the page whether they be <form> or <href> passed?
i tried
but this only displays the variables passed through a <href> link and not <form> variables. any other solutions.
thanks in advance

Try session_cache_limiter('private_no_expire');
[php_man]session_cache_limiter[/php_man]()
[php_man]session_cache_expire[/php_man]()

I done this, so i assume that what will happen is that the session will last 8 hours?
If i open popups from home.php will these still keep the session open?
Code: Select all
session_cache_limiter('private');
$cache_limiter = session_cache_limiter();
session_cache_expire(28800);
session_start();
$cache_expire = session_cache_expire();

Yeah, I'm pretty sure this is the general idea. If you do popups, make sure you call those session functions on those pages as well.

The session does not destroy when you re-login.
I have used
Code: Select all
<?php
session_start();
session_destroy();
session_unset();
?>
seems to cache now. how can i make sure the entire cache resets when you click on the logout link?

I haven't done this type of caching, but this _might_ work
session_cache_expire(0);
session_destroy();

OK, I realized caching it is not a good idea.

any other ideas?

Actually, I'm wrong. Try doing:
Code: Select all
<?php
session_cache_limiter('nocache');
session_cache_expire(0);
session_start();
session_destroy();
?>

Keep using the caching stuff, but use this to set the default back to non-caching sessions and then expire and destroy the cache and session. In concept this seems like it would work, but again I'm not 100%.

i tried everything but once you set
session_cache_limiter('nocache');
you cant give a limiter time.
Once you set it to
session_cache_limiter('private');
you cant take the cache away until you give your browser a control+F5 refresh if you login as another user.
