I'm extending the controller class with MY_Controller and using this code:

Code:
$this->load->vars('head', $this->load->view('_inc/head', '', TRUE));

To create commmon template pieces like a header footer sidebar etc.

Can I pass data from a controller method to one of these vars so I can have a unique <title> on each page?

like in my controller, I would have

Code:
$data['title'] = "fish food";

$this->load->view('page_view', $data);

and in the view I have

Code:
&lt;head&gt;

&lt;?=$head?&gt;

&lt;/head

I use this function (thanks to zwero for showing me):

./system/application/libraries/MY_Loader.php

Code:
&lt;?php

class MY_Loader extends CI_Loader {

    function vars($vars = array(), $val = '')

    {

        if ($val != '' AND is_string($vars))

        {

            $vars = array($vars => $val);

        }

        $vars = $this->_ci_object_to_array($vars);

        if (is_array($vars) AND count($vars) > 0)

        {

            foreach ($vars as $key => $val)

            {

                if(strncmp('view:', $key, 5) == 0)

                {

                    $this->_ci_cached_vars[substr($key,5)] = $this->view($val,'',TRUE);

                }

                else

                {

                    $this->_ci_cached_vars[$key] = $val;

                }

            }

        }

    }

}

So loading some data from an imaginary model, and loading the a view using that data, I can do something like this:

Code:
$this->load->vars(array(

        'head_data' => $this->my_model->get_head_data(),

        'view:head' => 'head_view'    # This is where the magic happens, the view is 

        # loaded into a variable named "head". Just ensure that you remember to load the

        # variables needed by the view before you load the view variable itself.

    ));

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

Hope this helps.

thanks!

Looks a little bit complicated, but I may try to implement it.

I guess I could also take the cowards way out and do something like this.

MY_Controller

Code:
$this->load->vars('doctype', $this->load->view('_inc/head', '', TRUE));

// doctype and opening head tag 

$this->load->vars('head', $this->load->view('_inc/head', '', TRUE)); 

// all my css and js and meta stuff

// and closing head tag

then in the view

Code:
&lt;?=$doctype?&gt;

&lt;title&gt;Page Title Here&lt;/title&gt;

&lt;?=$head?&gt;

Yes, that will work just fine (so long as you've loaded any variable dependencies first, of course).

Sorry, it never occurred to me that $this->load->vars() accepted a pair of parameters. I'm too used to calling it all with a single array.
