PHP Session in a page-template?

I know there are a lot of posts out there in how to enable sessions in wordpress. somehow NOTHING works for me.

i’m currently working on a custom page template where i want to save a session cookie.

session_set_cookie_params(0, '/', '.mydomain.com');
				//session_start();
				if(!isset($_SESSION['ftp-password']) ) {
					$_SESSION['ftp-password'] = $_POST['password'];
				}

				var_dump(ini_get_all('session')); //i can't find the cookie, It's not getting saved

I’ve already added the following code to wp-config.php

// enable sessions
if (!session_id())
session_start();

However i can’t quite figure out why my session doesn’t get saved.
Any idea?
