Login box on multiple pages

[eluser]Funky Fresh[/eluser]
Hey Hey,

I have been reading the article at http://codeigniter.com/wiki/Header_and_F...ge_-_jedd/ for quite some time and i cant wrap my head around how to pull this off.

So im going to post my code here in hopes that someone can help me.

Im trying to include a 'login box' on certain pages of my site ... if you could check it out that would be great.

I extended my core controller and created MY_Controller.php which is as follows

Code:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class MY_Controller extends Controller
{

    function MY_Controller ()
    {
        parent::Controller();
        
        $this->load->helper('form');
        $this->load->library('form_validation');        
        
        // Login Box Info Start
        $tmp_data['check_this_out'] = 'insert data here';
        $tmp_data['config_options'] = 'some config rubbish here';
        
        $this->data['login_box_view'] = $this->load->view('inc/login_form', $tmp_data, TRUE);
        // Login Box Info End
    }

}

In the view that i want to display the login box i have the following code.

Code:

<?php echo $login_box_view; ?>

When i load up the page, i get the following error

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: login_box_view

I think im missing something hehe ... can someone please help me out.

Cheers,

Can you post your other controller code? Like the code that is being executed where your loading the view thats giving you the error?

Im using the Tank Auth library, here is the controller

Code:

<?php if (!defined('BASEPATH')) exit('No direct script access allowed');

class Front extends MY_Controller {

    function Front()
    {
        parent::MY_Controller();
        
        $this->load->library('tank_auth');
        $this->load->helper('form');
        $this->load->library('form_validation');            
    }
    
    function index()
    {
        if (!$this->tank_auth->is_logged_in()) {
            $this->load->view('notloggedin_index');
        } else {
            $data['user_id']    = $this->tank_auth->get_user_id();
            $data['username']    = $this->tank_auth->get_username();
        
            $this->load->view('loggedin_index', $data);
        }
    }
}

It's the line that loads the notloggedin_index view.

Change this:

Code:

$this->data['login_box_view'] = $this->load->view('inc/login_form', $tmp_data, TRUE);

To something like:

Code:

$data['header']    = $this->load->view('inc/header', $tmp_data, TRUE);
$data['login_box'] = $this->load->view('inc/login_form', $tmp_data, TRUE);
$data['footer']    = $this->load->view('inc/footer', $tmp_data, TRUE);

Then pass it to another view:

Code:

$this->load->view('inc/login_page', $data);

#Then pass it to another view:

$this->load->view('inc/login_page', $data);

And on the view:

Code:

<?php echo $header; ?>
<?php echo $login_box; ?>
<?php echo $footer; ?>

In your MY_Controller your saving your data into a class variable called data. In your controller your passing the local variable data and not the class variable.

Change this:

Code:

$data['user_id']    = $this->tank_auth->get_user_id();
            $data['username']    = $this->tank_auth->get_username();
        
            $this->load->view('loggedin_index', $data);

to:

Code:

$this->data['user_id']    = $this->tank_auth->get_user_id();
            $this->data['username']    = $this->tank_auth->get_username();
        
            $this->load->view('loggedin_index', $this->data);

Hey SpooF,

That worked perfect ... thanks heaps for that ... So to sum it up ( sorry about this ) ... using $data is only local and when using $this->data is more global?
