Question

How to save the state of $_POST['username'] in PHP. I made a form to login, that form posts to MySql but it also posts to the users page, how to save that state of the user-page so when te user goes to another page the the state wil still be saved until you log in again.

Answer 1

Use Sessions to store it. Find about it here. Use it like below.

set it like below,

session_start();
$_SESSION['username'] = $_POST['username'];

get that back at another page as

session_start();
$username = $_SESSION['username'];
