Hooks don't work

[eluser]Kamarg[/eluser]
If you want to use hooks for this, it seems like the appropriate hook would be display_override. Then you just need to do something like the below.

Code:

$CI =& get_instance();
$content = $CI->load->view('header_file') . $CI->output->get_output() . $CI->load->view('footer_file');
$CI->output->_display($content); // Maybe just echo $content?

Note that this could also be done by having a _output function within your MY_Controller and making sure all your controllers extend MY_Controller.
