$data['title'] = "Testing Twig!!";
$this->twig->display('view.html', $data);

CodeIgniter helper functions

If you want to use CodeIgniter helper functions in Twig templates do this in your controller.

$this->load->library('twig'); // load the Twig library
$this->load->helper('url'); // load the CodeIgniter URL helper
// map the base_url() function as a Twig function 
$this->twig->add_function('base_url'); 

Then in your Twig view call the base_url() function like this

{{ base_url() }}
