In the controller:
class MyController extends Controller {
public function __construct ( ) {
parent::__construct ( );
$this->load->library ( 'masterpage' );
}
public function index ( ) {
$this->masterpage->setMasterPage ( 'masterpage_default' );
// content_index is the view file to use.
// content is the tag in the masterpage file we want to replace.
$this->masterpage->addContentPage ( 'content_index', 'content' );
// Show the masterpage to the world!
$this->masterpage->show ( );
}
}
