How are you detecting postback?
No need to tell me how CI does it, because I already know. How are you doing it?

Maybe you could explain how CI does it.

Maybe I can't and was just bluffing.
count($_POST) == 0

You could extend Controller and add something like the following (to MY_Controller):
Code:
function is_post() {
return $_SERVER['REQUEST_METHOD'] == 'POST';

My submit buttons usually have: name="submit", so I just:
Code:
if ($this->input->post('submit'))
{
// do it

I check for some specific required field, usually the most 'obvious' one, and I also have the tendency to put hidden fields in my forms that I check for to be definitive on just what form is being submitted. Some forms I actually use this to handle form submission in my constructor or MY_controller (I handle login this way, so if there is $this->input->post('login_request') is true I try to log the user in before doing anything else). The advantage there is that I can build any form, anywhere on the site, in any way I want and have it 'just work' so long as I stick the right hidden form field or even drop-down field option in a form somewhere.

Looks like all the intuitive ways to detect postback have been mentioned. Thanks, everyone, for all the feedbacks.
My implementation is the same as wabu's way, except I extend Form_validation instead.
