CI Session & Cookie Error

[eluser]midknight[/eluser]
Hey Guys!
Been flipping through my files like crazy trying to find out why I am getting errors revolving around sessions and cookies. Been trying to search the forum for similar problems/solutions but I haven't seen anything yet (or it is there just didn't jump out). If someone could help me out that would be awesome!.

Thanks!

Code:

class dhr extends Controller
{

    /**
    * Constructor
    */
    public function __construct()
    {
        parent::Controller();
        session_start();   ----> Causing the issue or so I think it is.
    }

PHP 5.2.2/MySQL 5.0.45/Linux - Server
Checked all of my files for whitespace
Cookie domain is set to the domain name .domainname.com

Can your application write to /var/php_sessions?

Why are you using PHP sessions and the CI session class anyway?

[eluser]midknight[/eluser]
I am not wanting to use PHP sessions I want to use the CI sessions. Not sure why this is happening.

/var/sessions would only matter if I was using PHP session no?

Are you loading the Sessions Class or are you autoloading?

Enjoy

I am autoloading the session class along with email, database and validation.

a) if you are using CI sessions then don't ever use session_start() - CI can't override a true php function, at least I don't believe it can.

b) make sure that /var/php_sessions exists and is writable by your webserver (apache|www-data|httpd|soemthing else) in case you aren't using the database to store the session data.

brianw1975:

Thanks for tip a) that did the trick. I am using a DB to store the session data as well.

LOL from your other posts on the forum I could see why this question gets you mad with us N00Bs!
