Problems with Codeigniter Session Class

Question

this is my problem... I added to the construct of CI_Controller these lines

    $this->load->library("session");
    if($this->session->userdata("var")==FALSE)
    {
        $this->session->set_userdata("var", "value");   
    }

And when I use $this->session->userdata("var") in a child class, it doesn't have a value. I tested that by showing the value of $this->session->userdata("var") in the construct of CI_COntroller and in the construct of the child class and it shows me the value on the father but no on the child.

There is another thing, after reload the page about 3 or 4 times. It works very well.

I will be grateful for your answers. (And I'm sorry I'm not an English speaker)

mmmm... I use the library session of codeigniter, does not it work with cookies?... I don't understand you — user2065593

The Session library stores data in cookies by default, unless you set the config to use the database to store sessions. — landons

Can you check Firebug or the Webkit console to see if you're getting a Set-Cookie response header on the request? — landons

you should do

$this->load->library("session");
    if(!$this->session->userdata("var"))
    {
        $this->session->set_userdata("var", "value");   
    }

cause userdata() method returns false and true if isset or not session data.

Aren't !$var and $var == FALSE same expression?

You could have done it like this

$this->load->library("session");

$var    =   $this->session->userdata("var");

if(!$var)
{
    $this->session->set_userdata("var", "value");   
}
