Lost session

[eluser]Moiz[/eluser]
well the issue here is only IE .... why does it happen only on IE.

Works perfectly fine with Mozilla, Opera ..etc. but when i use IE .. there are multiple entries in the database with diff session ID's and the values of the Session as different.

Also ... using IE : my IP address is shown as sumthing else and using Mozilla .. its sumthing else ! im sure its coz of the HTTP_x_FORWARDED value ... but why are multiple entries made in the database for each page i click

Please tell me session time to update
$config['sess_time_to_update'] = ?????

[eluser]Moiz[/eluser]

Code:

$config['sess_cookie_name']= 'ma_session';
$config['sess_expiration']= 1200;
$config['sess_encrypt_cookie']= TRUE;
$config['sess_use_database']= TRUE;
$config['sess_table_name']= 'ci_session';
$config['sess_match_ip']= FALSE;
$config['sess_match_useragent']    = TRUE;
$config['sess_time_to_update']     = 600;

Would you mind to replace:

$config['sess_cookie_name']= 'masession';
$config['sess_expiration']= 7200;
$config['sess_encrypt_cookie']= TRUE;
$config['sess_use_database']= TRUE;
$config['sess_table_name']= 'ci_session';
$config['sess_match_ip']= FALSE;
$config['sess_match_useragent'] = TRUE;
$config['sess_time_to_update'] = 7200;

Actually .. a 2 hour time out is out of the question. it posses a security risk on public computers. the max time of a session time out as per client requirement would be 30 mins. anyway, i have set these vals :

Code:

$config['sess_expiration'] = 3600; // one hour

im goin to test it online rather than a local development env, so if there are any issues ... i'll get back to this thread

[quote author="vibeesh p" date="1240402474"]Please have a try

Check the encoding of your ci_sessions database table field

change it to utf8_general_ci[/quote]

I've already sorted this in another way.
But this tip feels like the solution.
My encoding was set to latin1_swedish_ci.
I'll let y'all know if I try this again.

Thanks!

Hi.
Have tried with some of the suggested methods and... no luck.
Here is my temporal solution while this issue can be solved.

It is pretty obvious but hope it helps:

Code:

<?php
if (! defined( 'BASEPATH' ))
    exit( 'No direct script access allowed' );

require_once 'system/libraries/Session.php';

/**
* Solución temporal al issue de pérdida de sesión
*/
class MY_Session extends CI_Session {
    
    function MY_Session() {
        parent::CI_Session();
    }
    
    function set_userdata($name, $value) {
        $_SESSION ['my_session'] [$name] = serialize( $value );
    }
    
    function userdata($name) {
        
        if (! isset( $_SESSION ['my_session'] [$name] )) {
            return false;
        } else {
            return unserialize( $_SESSION ['my_session'] [$name] );
        }
    
    }
    
    function unset_userdata($name) {
        unset( $_SESSION ['my_session'] [$name] );
    }

}

I was having the same issue and I believe it was caused by certain UTF-8 characters in the session. As a quick fix I used the base64_encode/base64_decode functions in the _serialize/_unserialize methods like this:

Code:

function _serialize($data)
{
    if (is_array($data))
    {
        foreach ($data as $key => $val)
        {
            $data[$key] = str_replace('\\', '{{slash}}', $val);
        }
    }
    else
    {
        $data = str_replace('\\', '{{slash}}', $data);
    }
    
return base64_encode(serialize($data));
}

Code:

function _unserialize($data)
{
    $data = @unserialize(base64_decode(strip_slashes($data)));

    if (is_array($data))
    {
        foreach ($data as $key => $val)
        {
            $data[$key] = str_replace('{{slash}}', '\\', $val);
        }

        return $data;
    }

    return str_replace('{{slash}}', '\\', $data);
}

Certainly not ideal but it got the job done.

Found this which explains the rationale:
PHP Serialize

Having the same issue - James_F's solution fixes it for me. I was getting it using the cart class, adding items that had ( or other characters in it.
