Codeigniter increase session time out not working

Question

I am new to codeigniter framework. I have a problem with session time out with pages. Right now I had enabled with the ip match ,user agent matching but doesn\'t work.

Answer 1

Finally i found the solution for the problem.

The following ways to increase or decrease the session time out. 1.

  ini_set('session.gc_maxlifetime', 60);

  config->config.php

  $config['sess_expiration'] = ''; //in seconds.

2.

 $config['sess_time_to_update'] = '' ;//in seconds (as same in sess_expiration seconds)

3.If you are checking in login controller and all controller for the session data as

$_SESSION['data'] == 'your login id or role or something

.this is not getting session expired the session datas.but we need to check the check with $this->session-> userdata('your id or data need to check') and before once login successfull then need to assign the value to the session as $this->session->set_userdata('your id or something');

while checking the session = $this->session->userdata() is empty or zero need to session_destory() and then need to redirect to your home page. Another way to increase :

1. If your site was running in apache2 and only one website means we can directly mention the session_gc_maxtime.

These two ways i had tried and i found the solution for the session time out.its working fine for me.

Thanks to all.

Answer 2

if you dont have ci_sessions table in your database, create it using the following script.

CREATE TABLE IF NOT EXISTS  `ci_sessions` (
    session_id varchar(40) DEFAULT '0' NOT NULL,
    ip_address varchar(16) DEFAULT '0' NOT NULL,
    user_agent varchar(120) NOT NULL,
    last_activity int(10) unsigned DEFAULT 0 NOT NULL,
    user_data text NOT NULL,
    PRIMARY KEY (session_id),
    KEY `last_activity_idx` (`last_activity`)
);

use $this->session->set_userdata($array); to get session data. Then it should work properly
