can only seem to access $_SESSION from one model object

[eluser]jmadsen[/eluser]
Hi,

I am unable to use the CI session lib because I am trying to work with a multi-dim array in my session variables, so I am switching over to normal sessions.

However, I'm having a problem.

my main Controller, I load

Code:

parent::Controller();

        $this->load->model('page_model');
        $this->load->model('nav_model');

Inside page_model functions I can access the $_SESSION var, but from the other model, the controller, or views I always get this error:

"Severity: Notice
Message: Undefined variable: _SESSION"

I AM autoloading the session lib still, but am NOT calling session_start() from anywhere (nor does adding it seem to make any difference). It seems strange that it is not an "all or nothing".

The only thing I can think of is that my $_SESSION is really a class variable, and is just fooling me. In which case, how should I be setting this up correctly?

Any idea what I should be looking for?

Thanks,

jeff

I got it:

I DID need to use session_start(), but couldn't find the right place to put it.

All happy now!

I take it that this way isn't sufficient?

Code:

$user_info = array("test"=>array("unit1"=>"1","unit2"=>"2"));
$this->session->set_userdata($user_info);

$data =  $this->session->userdata("test");
echo $data['unit1'];

not really.

my array looks more like this:

Code:

$user_info = array("test"=>array("unit1"=>"1","unit2"=>"2","unit3"=>array("try1"=>2,"try2"=>4)));

and I am looping through certain parts of the different levels at different times, so having to keep passing it into intermediary vars like your suggestion is cludgy.

I know I could write something to do it, but why bother when I have the $_SESSION? There's no login or personal data involved, and I've never had any issues with $_SESSION.

I've seen a suggestion for some code to allow something like:

Code:

$this->session->set_userdata('test'['unit3'][$try_var]);

that's what I am really after.
