return cookie value

Please provide us with a little bit more information. First, what exactly do you mean by "output nothing." That appears to be the expected behavior from a fleeting glance at your code; there are no statements made that output anything.

I don't know what you intended, maybe it was just a typo, but you are calling setcookie, PHP's built-in function, not set_cookie, CodeIgniter's alias for Input:et_cookie. Maybe that's what you wanted, but we can't tell from what you have provided here.

Provide some more context so we can help you better.
