[eluser]Volkscom[/eluser]
Hi,

I'm using php session functions in my project and not using codeiniter's session class.I need to set session time out.How can I do this?.
I write the following function in helper and this give an error

in myhelp_helper.php{

function sesion_timeout(){
// set timeout period in seconds
$inactive = 60;
// check to see if $_SESSION['timeout'] is set
if(isset($_SESSION['timeout']) ) {
$session_life = time() - $_SESSION['start'];
if($session_life > $inactive)
{ session_destroy(); }
}
$_SESSION['timeout'] = time();
}
}

I anyone know to solve this,Please help me.......
Thanks in advance

There is no need to write your own functions for the sessions as CodeIgniter has provided a class for it. There is no difference between CodeIgniter sessions and PHP sessions (in case of confusion)...

I say, use CodeIgniters Session library. You can set session timeouts in the config file.

Yes there is, codeigniter sessions use cookies by default, or the database if you have that option enabled. There is a native session library, though.

@noctrum: I assumed it was using php sessions, however you are correct in saying it uses cookies.
@Volkscom: I would create my session, somewhat like what I have below.

Starting the session:

Code:

function session_create()
{
    session_start();
    
    // timeout in 60 seconds
    $timeout = 60;
    
    $_SESSION['timeout'] = time() + $timeout;
}

Checking if the session has timed-out

Code:

function session_timed_out()
{
    if( time() > $_SESSION['timeout'] )
    {
        session_destroy();
        return TRUE;
    }
    return FALSE;
}

Use it like so:

Code:

session_create();

if( session_timed_out() )
{
    // do something if the session is no longer valid (timed-out)
}
else
{
    // continue the script because the user session is still valid
}

hi,
Thanks for your reply!....
I tried your function and wrote it as a helper.I need to set session time out, when the user is idle for a long time.Now the function is not checking whether the the user is idle for a long time or not. If know how to solve, please help me..
