Session data lost between redirects

[eluser]Kobus M[/eluser]
Hi,

This is driving me insane, and I don't know what is causing the problem.

I have posted a brief note on someone else's post that has a very similar problem, but there is no responses there, and perhaps mine is not 100% the same as his problem.

I am using CodeIgniter 1.7.2 (didn't upgrade yet, not sure I am seeing a need to do so yet, as I am still struggling to learn CI).

I wrote a little controller that handles login functionality for me, that records login attempts, failed attempts, last login information, etc. etc. etc., and after a successful login, I use redirect('controller/method') to change to the appropriate controller once login is successful.

Upon redirect, the session variables are lost, and therefore the user is not recorded as logged in.

Is there a better way to preserve session data than with a redirect? I saw a few post of people using flashdata to do this, but my attempts at that were fruitless.

Could anybody please shed some light on what I am doing wrong, please?

Before someone jumps on my back for not providing full information. It seems that people are quick to do that here.

CI version: 1.72
Custom libraries: NONE

Sessions config:

Code:

$config['sess_cookie_name']        = 'admaxsession';
$config['sess_expiration']        = 14400;
$config['sess_encrypt_cookie']    = TRUE;
$config['sess_use_database']    = TRUE;
$config['sess_table_name']        = 'CI_ADMAX_SESSIONS';
$config['sess_match_ip']        = TRUE;
$config['sess_match_useragent']    = FALSE;
$config['sess_time_to_update']     = 14400;

I tried various options. encryption, no encryption. Database, no database, upped the expiration and time to update settings. All possible options in the settings above that I could fathom, and still not working.

I have also followed advice on more than 8 topics with concrete solutions for similar problems here, none solving my problem.

Thanks!

How you can identify, that session variables are lost? You dont forgot to load session library, before try to retrieve session data, right?

just simple test, change your config to this :

Code:

$config['sess_expiration']        =0;

If your running Internet Explorer go into Ie Internet options
and check your cookie restrictions!

My session library is loaded in my config file by default. To test, I loaded the library even in each controller's index function. Still does not resolve.

How do I know the session variables are being lost? I log sessions in the database, and here is what I see:

1. Every page load, there is a new session ID.
2. Every page load, the user_data fields are blank for that page load's entry.

Is there something else I am missing?

Thanks for the response. It does not make any difference.

Have a great day!

Just an idea... do you redirect to another directory?

If so the probem may lie in you cookie settings in config.php. You may have the cookie locked to a certain directory so when you redirect to a different one the cookie is not sent thus having no session data.

config.php

Code:

$config['cookie_domain']    = '.example.com';
$config['cookie_path']        = '/';

Make sure you have a trailing forward slash for cookie path and a fullstop in front of the domain.
