How to have a session that never expires ?

#1
Hello Dear CI Community,

I don't understand, i read the documentation and i set the sess_expiration on '0' as the doc said, but even with the tab always open in the browser (Chrome), the session never exceed 2 or 3 hours. After that time, the session file on the server is updated and the user data are removed... (i didn't define a save_path but it's automatically saved in the var/php folder of the server)

Here is my config code : 

PHP Code:
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 0;
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE

PHP Code:
$config['cookie_prefix']    = '';
$config['cookie_domain']    = '.mydomain.com';
$config['cookie_path']        = '/';
$config['cookie_secure']    = FALSE;
$config['cookie_httponly']     = FALSE

Ideally i would have at least a session that doesn't expire as long as the tab is open and in the best way, i would have a running session even when the user is off, in order to avoid to ask him to relog each time he comes to the website. 

If you have any ideas, it will be great !!  Heart

Thanks a lot !!

Cheers.

I have some questions and comments...what version of CI are you using? Your session settings appear to be correct. Although only one of my cookie config settings is different: $config['cookie_domain'] is set to ''. Did you check your PHP.ini Session settings?

Thanks for your help, i use the 3.1.6

Before, the cookie_domain was see to '' and it was the same issue, i just changed it recently cause i found someone on Stack Overflow who recommended it, but it didn't fix anything  Huh

this is the extract of my phpinfo() for the session, first value is the the local value, second is the master value.
If you see something abnormal, don't hesitate to tell me Smile

The only diff are session.cookie_domain, session.cookie_httponly, [b]session.name,  session.save_handler, [b]session.sid_length and [/b][/b]session.use_strict_mode.

The problem is here

PHP Code:
$config['sess_save_path'] = NULL

When using the file driver the value must be an absolute path to the folder to be used for the session files.

Read the Files Driver Documentation until you see the comment about absolute paths.

Thanks for the info !  Heart
But i don't get it, actually when $config['sess_save_path'] is empty, the default path is "/srv/data/var/php/www" as you can see in my phpinfo()
Do i need to copy/past that in the $config['sess_save_path'] or do i need to create another custom folder ? 

Thanks a lot for your help !!

Read the documentation one more time. Oh, never mind.  It says

Quote:[The files driver] doesn’t support PHP’s directory level and mode formats used in session.save_path,

Yes, you could explicitly set it like this.

PHP Code:
$config['sess_save_path'] = "/srv/data/var/php/www"

But that's not a good place if  /srv/data/var/php/www is where index.php is located. It is wise to put session storage outside a site's public accessible folders. You should consider creating a different folder. Perhaps /srv/data/var/php/sessions/. The owner should be www-data and with permissions set to 0700. If you were to create what was just described then you would use

PHP Code:
$config['sess_save_path'] = "/srv/data/var/php/sessions"

I tried your solution but always the same issue, after a short time the session expires...

When you say "the session expires" you mean that the session data is gone?

I have a GitHub Repository that is designed to test CodeIgniter (v3.x.x) session configuration. It contains one controller and one view file. Give it a try it may help you determine if you have a config issue or some other "logic" problem.

@Coool6,
This probably doesn't matter but what version of PHP are you using?

Earlier I recommended

PHP Code:
$config['sess_save_path'] = "/srv/data/var/php/sessions"

Which might be wrong because it is missing a trailing slash. Try this.

PHP Code:
$config['sess_save_path'] = "/srv/data/var/php/sessions/"
