Problems with the native session - El Forum - 05-20-2009

[eluser]Zorancho[/eluser]
Hi there, i have MY_Controller in the libraries folder and in its constructor i am starting a native session like this:
class MY_Controller extends Controller
{
public function MY_Controller()
{
parent::__construct();
session_start();
}
}

It worked well on my server, but then i put the application on real server and it gets me this error:
A PHP Error was encountered

Severity: Warning

Message: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at system/application/libraries/MY_Controller.php:1)

Where i am suppose to start the session before any output starts?
Thanks in advance
Zoran

I would just put the session_start() in the index.php file
That way you know its going to start before anything else

I removed the autoloading of the session library and i am using only native sessions, but i still get this error:

Are you sure you don't have any whitespace in MY_Controller on line 1?

Out of curiosity, why are you using native sessions over CI sessions?

I will do all of it with the CI Sessions.. but this is how my controller looks like
<?php if(!defined('BASEPATH')) exit('No direct script access allowed');

class MY_Controller extends Controller
{
public function MY_Controller()
{
parent::__construct();
}

public function destroy_sess()
{
$this->session->sess_destroy();
unset($_SESSION['userid']);
unset($_SESSION['logged_in']);
unset($_SESSION['role']);
redirect('servis/');
}
}

I even deleted MY_Controller, but still was getting this error again:
Message: Cannot modify header information - headers already sent by (output started at /home/bpetrusev/servis/system/application/libraries/MY_Controller.php:1)
And i am doing update and commit via svn, but i am still getting the error like MY_Controller still exists. I checked everywhere, but it still gives me the same error.

Either your browser is caching the page, or you're editing the files in the wrong location. If MY_Controller.php has been deleted, then it can't possibly be causing an error, can it?

Well, it would be causing an error saying it can't be found Tongue
But thats not the error we're getting here :-S

I meant in the sense that the error is occurring inside the supposedly deleted script. Don't be so facetious! Tongue

autoload session then forget about calling session_start(), it does the job for me... in this way you can use both the CI session and native sessions, IMO -> i think you autoload the session then calling again session_start() would cause the error.
