PHP: session isn't saving before header redirect

I have read through the php manual for this problem and it seems quite a common issue but i have yet to find a solution. I am saving sessions in a database. My code is as f

Answer 1

I had the same problem recently. I'm writting a customized MVC Website for school and, as everyone told, start_session() must be written in the very first lines of code.

My problem was THE LOCATION of "session_start()". It must be the first lines of your global controller, not the first lines of the view. $_SESSION was not accessible in controller's files because it was only initiated when the server render the view.

Then, I'm using session_write_close() after the header('location: xxx.php') call to keep session variables for the next request.

ex:

globalController.php :

//First line
session_start();
require_once('Model/Database.php');
require_once('Model/Shop/Client.php');
...

logonController.php:

...
//Users is validated and redirected.
$_SESSION['client'] = $client;
header('location: index.php');
session_write_close();

Hope it solved your problems.
