Where is the this code coming from?

[eluser]matt6805[/eluser]
I have a controller passing a header template file to a view like this:

Code:

class Home extends Controller {

    function Home()
    {
        parent::Controller();    
    }
    
    function index()
    {
        $data['title'] = 'Homepage';
                //this is the navigation
        $data['nav'] = $this->load->view("template/nav");
        $this->load->view('home', $data);
    }
}

Now this is where it get's weird. If i take <?php echo $nav; ?> OUT of the homepage view, i still see the navigation! I can't get rid of it. This is the only controller passing anything to the homepage view. Even if i create a new blank home view file, the nav is still there.

Has anyone experienced something like this?

When in doubt, read the user guide: http://ellislab.com/codeigniter/user-gui...views.html ... alll the waaaay down at the bottom... where it talks about the third parameter...

There is a third optional parameter lets you change the behavior of the function so that it returns data as a string rather than sending it to your browser.

Right now you're loading and viewing it... not returning it...

You could also just load the nav in the views that need it, and omit it where you don't want it.

Loading the Nav as needed is not the issue i was having. As the documentation says, when you pass the view as a variable rather then just loading a view, you have control over where and when it displays.

So for example:

Code:

$data['nav'] = $this->load->view("template/nav");

This will load the nav even before any HTML is written to the browser. It puts it at the very top of the page, and I have no control over it.

But, if I do this:

Code:

$data['nav'] = $this->load->view("template/nav", "", true);

Now, in my view, I have access to the contents of "template/nav" though the variable $nav. I can place it and process it anywhere i wish. That's the difference.
