Session between controllers - El Forum - 11-01-2009

[eluser]ping timeout[/eluser]
Hello,
I started an application with CI. I've made Controllers for the registration page, activation, login and user pages.
In my controllers/login.php function index(); I have someting like:

Code:
//code

        if ($this->form_validation->run() == FALSE)

        {

            $this->load->view('login');

        }        

        else

        {    

            $time = time();

            $agent = $this->input->user_agent();    

            $username = array('username' => set_value('username'), 'logged_in' => TRUE);        

            $this->session->set_userdata($username);

            $this->load->view('personal');          

        }

And in views/personal.php

Code:
<h1>Hello &lt;?php echo $this->session->userdata('username'); ?&gt;</h1>

&lt;?php if ($this->session->userdata('logged_in')==TRUE) echo anchor('register', 'Register'); ?&gt;

This works ok it shows both my username and the anchor, but if I change the url or click on the link from the anchor it redirects me to the register page where I have

Code:
function _is_logged_in()

    {

        if ($this->session->userdata('logged_in')==TRUE)

            $this->load->view('personal');

        return TRUE;

    }

And it doesn't do anything, also it doesn't know the username...
I tested a few times, with both database session and cookie sessions, and with bot autoload session library and manual load... What can I do?

Try setting the session variables individually and then echoing directly after to see if it's even getting set at all.

I've changed my code:

Code:
//$username = array('username' => set_value('username'), 'logged_in' => TRUE);        

            //$this->session->set_userdata($username);

            $this->session->set_userdata('username',set_value('username'));

            $this->session->set_userdata('logged_in',TRUE);

            echo $this->session->set_userdata('username');

            //$this->load->view('personal');          

        }

And it just shows a blank page.
And if I let this:

Code:
//echo $this->session->set_userdata('username');

            $this->load->view('personal');

It shows the Hello $username message and anchor.
I've tested with:

Code:
echo $this->session->set_userdata('username');

            $this->load->view('personal');

And the message is just Hello, no $username or anchor.

OK, just do this in your controller

Code:
$this->session->set_userdata('username','test');

$this->session->set_userdata('logged_in',TRUE);

echo $this->session->userdata('username') . " - logged_in=" . $this->session->userdata('logged_in');

What do you get?

I get:
test - logged_in=1

Problem solved.

Looks like set_value('username') doesn't contain anything and instead of checking for logged_in == TRUE just check for logged_in:

Code:
function _is_logged_in()

{

   if ($this->session->userdata('logged_in')) {

      $this->load->view('personal');

      return true;

   }

   else {

   return false;

   }

}

NO, it's not because of set_value(‘username’) - because it has the right value( no form validation errors) and anyway I changed the code to:

Code:
$this->session->set_userdata('username','test');

        $this->session->set_userdata('logged_in',TRUE);

        $this->load->view('personal');

And in views/personal I have

Code:
<h1>Hello &lt;?php echo $this->session->userdata('username'); $username=$this->session->userdata('username'); ?&gt;</h1

&lt;?php echo anchor('personal/user', 'User'); ?&gt;

In controller personal, function user I have:

Code:
function user()

    {

        $this->load->view('personal_user');

    }

views/personal_user:

Code:
<h1>Hello &lt;?php echo $this->session->userdata('username'); $username=$this->session->userdata('username'); ?&gt;</h1

&lt;?php echo anchor('personal', 'Personal'); ?&gt;

In personal I see Hello test, when I click on User, I get only Hello.

I don't get it, anything (captcha, email, form validation...) works fine till here...

Also noticed something:

I've changed my code and it looks like this:

Code:
class Personal extends Controller

{

    function __construct()

    {

        parent::__construct();

    }

    function index()

    {

        $this->_is_logged_in('personal');

    }

    function user()

    {

        $this->_is_logged_in('personal_user');

    }

    function _is_logged_in($link)

    {

        if ($this->session->userdata('logged_in')===TRUE)

            $this->load->view($link);

        $this->load->view('login');

    }

}

1. index.php/personal shows views/login
2. index.php/personal/ shows views/login
3. index.php/personal/user shows views/personal_user only for IE, in FF it shows login
4. index.php/personal/user/ shows views/login

Change logged_in = 1 not true logged_out set to 0
