access session data inside ouput class in codeigniter

Question

I want to access codeigniter session data ie $this->session->userdata('session_id');

inside ouput class ie secure_system_folder/core/Output.php .

Answer 1

$CI =& get_instance;
$sess_id = $CI->session->userdata('session_id');

But what you're probably looking for is hooks , they're a much easier way to extend the core without directly editing (and therefore possibly breaking) core files.
