Can you be more specific? Any variables you want to pass through to a view should be defined in an array, and passed as the second parameter when loading a view.

Code:
class site extends Controller {

   function index()

   {

        $data = array(

               'main_content' => 'mypage',

           'menu_name' => 'home',

               'title' => 'titolo di mypage',

               'description' => 'descrizione di mypage',

               'keywords' => 'keywords di mypage'

          );

        $this->load->view('includes/template', $data);

   }

   function about()

   {

        $data = array(

               'main_content' => 'about',

           'menu_name' => 'about',

               'title' => 'titolo di about',

               'description' => 'descrizione di about',

               'keywords' => 'keywords di about'

          );

        $this->load->view('includes/template', $data);

   }

this is my controller, as you can see there is menu_name in both function ... i'd like to show them (both) in one view. Or have a function that select them in another variable, and then pass it to the view.

You could do it this way:

Code:
class Site extends Controller {   // Fixed case of class name

    function __construct()  {

       parent::Controller();

       $this->data = array(

                      'common_item' => 'common string here',

                      );

    }

// In your other methods you could merge_array() with a new construct, overwriting common bits,

// adding other bits, etc.  Obviously you would then pass $this->data to your views.

Note that menu_name does exist in both functions, but has a different value in both functions, so I'm not sure how you can cut down on the number of times you define that variable.

You might also want to hit the [url="/wiki/FAQ"]FAQ[/url], hit the commonly asked question 'I'm repeating lots of bits of code, is there anyway around that?' and then follow the link to my rant. Also accessible from the [url="/wiki"]main wiki[/url] front page if you follow the Approaches yellow brick path. It sounds like what you're trying to do is covered, at least in part, by that.
