Re: [PHP] Overriding session length in existing session?
Hi Scott, I'm glad you resolved your problem. I'm curious about your method though, as it seems to be an entirely different approach to my own. How do you refer to your session data throughout the rest of the site? Do you always reference the $_COOKIE variables or do you utilise $_SESSION's at some point?

Everytime I hit a page I open a session with a session time of 7 days. If the user logs in correctly it stores the user information in $_SESSION, and then the site sees their login info and lets them past the login screen. If, at the login screen, they select public terminal it sets the session cookie length to 0 and regenerates the cookie to expire on browser close. Everything after that is pulled from the $_SESSION variable. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

public terminal I use the call set the session cookie length as 0 and
then regenerate the session cookie.
if ($public_term) {
session_set_cookie_params(0);
session_regenerate_id();
}
This way it defaults to a cookie of X days, but if it's a public
terminal it resets the cookie to expire at browser close.

Re: [PHP] Overriding session length in existing session?
The statement should be at the start of every php file that has php code in it. Hi Tedd, Normally I'd agree with this but having never used the function session_set_cookie_params() before, I looked it up, and the manual says to put it before session_start(). Set cookie parameters defined in the php.ini file. The effect of this function only lasts for the duration of the script. Thus, you need to call session_set_cookie_params() for every request and before session_start() is called.

Re: [PHP] Overriding session length in existing session?
This is called globally in *all* my scripts. In another script I'd really like to set the session to expire after the browser closes if a uses clicks public terminal or something. Howdy. Don't sessions expire when the browser closes as a rule? Do you mean the session cookie? Why not store the cookie, if one exists, in a $_SESSION variable in your header file and then refer to that in the rest of your code, rather than the cookie. Then when you want to destroy the session cookie, you can overwrite it and the existing session will still flow using the $_SESSION vars until the browser closes. It's early here, I hope that sort of makes sense and that I've at least sort of understood the problem.

Re: [PHP] Overriding session length in existing session?
I think that my suggestion is still a valid solution, someone correct
me if I'm wrong. Let's say your code went like this:
session_start();
// Check to see if the session variable has already been set, if not
if (!isset($_SESSION['var'])){
// Check to see if it's been stored in a cookie
if (isset($_COOKIE['var'])){
$_SESSION['var'] = $_COOKIE['var'];
}
// If not, set the session variable and store it in a cookie for 7 days
else{
$_SESSION['var'] = value;
setcookie (var, $_SESSION['var'], time()+86400 * 7, /,
.domain.com);
}
}
echo Here I am using my session variable, it's value is .$_SESSION['var'];
So if that's in the header of every page, but you want to make an
acception if the person is using a public computer, you just add
something like:
if ($_POST['public_terminal'] === TRUE){
// Delete the cookie
setcookie(var,,time() - 3600);
}
echo Here I am *still* using my session variable, it's value is
.$_SESSION['var']. and it will expire when the browser closes;

[PHP] Overriding session length in existing session?
I have a global header.php file that sets up a bunch of stuff: DB,
global variables, and does session_start(). My header.php looks like this:
#header.php
$cookie_life = (86400 * 7); // Cookies last for seven days
session_set_cookie_params($cookie_life,/,.domain.com,true);
session_start();
This is called globally in *all* my scripts. In another script I'd
really like to set the session to expire after the browser closes if a
uses clicks public terminal or something.
I thought I could just set the session cookie to expire after the
browser closes. Can I override the already started session by doing
something like this in my index.php:
#index.php
include('header.php');
setcookie(session_name(), '', 0 ,/,.domain.com);
When I do this the session expires IMMEDIATELY. I must be missing something?

Simple answer -- put session_start() at the start of your code -- first line.
