Sorry for the strange subject...

I'm using a pretty basic, home-brewed template system. Basically, my controller methods call a "render" function that calls a layout view, then the layout view then calls the "content view". I'd like to know if there's a way for a variable set in the content view to be used by the layout view. Perhaps it's more clear with examples:

A method from a controller:

Code:
function about()

{

    $data['page_title'] = 'About Our Wonderful Stuff';

    $data['extra_css'][] = 'about';

    $this->view->render($data, 'about');

}

Note: In the last line, 'about' is the name of the view to load.

The render function (in a custom library, view.php):

Code:
function render($data, $view, $layout='main')

{

    $data['view'] = $view;

    $data['CI'] =& $this->CI; // Passed through so that the layout file can call "load->view" in order to load the view.

    $data['data'] = $data; // Add $data to itself so that $data will be available in the view (after load->view is called a second time)

    $this->CI->load->view("layouts/{$layout}", $data);

}

Note: I'm adding $view to the $data array.

The "main" layout (as opposed to the "popup" layout or any other layout that the site may use):

Code:
&lt;html&gt;

&lt;head&gt;

    &lt;title&gt;&lt;?= SITE_NAME ?&gt; : &lt;?= $page_title ?&gt;&lt;/title&gt;

    &lt;link type="text/css" rel="stylesheet" href="/css/reset.css" /&gt;

    &lt;link type="text/css" rel="stylesheet" href="/css/main.css" /&gt;

    &lt;? if(isset($extra_css)): ?&gt;

    &lt;? foreach($extra_css as $css) :?&gt;&lt;link type="text/css" rel="stylesheet" href="/css/&lt;?= $css ?&gt;.css" /&gt;&lt;? endforeach; ?&gt;

    &lt;? endif; ?&gt;

&lt;/head&gt;

&lt;body&gt;

    <div id="main_header" class="clearfix">

        Site header goes here

    </div>

    <div id="main_content" class="clearfix">

        &lt;?= $CI->load->view($view, $data); ?&gt;

    </div>

    <div id="main_footer" class="clearfix">

        Site footer goes here

    </div>

&lt;/body&gt;

&lt;/html&gt;

Two things to note: The page_title and extra_css are variables. The "main_content" div is being "loaded" as it's a separate view.

And the "about" view:

Code:
<div id="toffees">

    Blah, blah blah...

</div>

So... my main question: How can I move page_title and extra_css from the "about" method in the controller into the "about" view? So that my "about" view would look like this:

Code:
&lt;? $data['page_title'] = 'About Our Wonderful Stuff'; ?&gt;

&lt;? $data['extra_css'][] = 'about'; ?&gt;

<div id="toffees">

    Blah, blah blah...

</div>

Is it possible?

You can use $this->load->view() like if you're inside the controller. Check it!

Oh, ok, that worked. So I don't need to use that $CI variable.

But, that still doesn't allow variables to be passed "backwards" does it?
