Session keeps getting Error

Question

On my index.php page I have this:

session_start();

if($_SESSION['logged_in']==true) {
   header("Location:home.php");
} else {
   header("Location:login.php");
}

On my login page, whenever the user correctly inputs the username and password I wrote this:

$_SESSION['username']=$username;

I used this as a reference to the future pages. But on my home.php, no matter what I do it keeps giving me this error:

 Undefined variable: _SESSION in C:\xampp\htdocs\website\home.php on line 8

The line 8 is:

$user= $_SESSION['username'];

why the two different session arrays? – Funk Forty Niner Mar 28 '17 at 22:51 — Funk Forty Niner, Mar 28 '17 at 22:51
and start the session in the 2nd file – Funk Forty Niner Mar 28 '17 at 22:52 — Funk Forty Niner, Mar 28 '17 at 22:52

In home.php you must call session_start(); at the very beginning of the file too.

Thanks! I thought that you will only have to call a `session_start()` only once per site. That's why I only placed it on the `index.php` – Dranreb Mar 28 '17 at 23:19

You need to call session_start() on each php file that is loaded.

Since php works by parsing each php file individually, you will have to have this at every page you have.
