Slim SessionCookie middleware not working - php

Question

This is my index.php
<?php
$app = new \Slim\Slim(
array(
'templates.path' => dirname(__FILE__).'/templates'
)
);
// Add session cookie middle-ware. Shouldn't this create a cookie?
$app->add(new \Slim\Middleware\SessionCookie());
// Add a custom middle-ware
$app->add(new \CustomMiddleware());
$app->get(
'/',
function () use ($app) {
$app->render('Home.php');
}
);
$app->run();
?>
This is my custom middle-ware:
<?php
class CustomMiddleware extends \Slim\Middleware {
public function call() {
// This session variable should be saved
$_SESSION['test'] = 'Hello!';
$this->next->call();
}
}
?>
And this is my template (Home.php)
<?php
var_dump($_SESSION['test']);
?>
which will output NULL, so the session variable is not saved. Also, when opening the cookies list in the navigator I don't see any. Why isn't the cookie of the session saved? I verified and made sure that the call() function of the SessionCookie class is executed.

How if you add your CustomMiddleware first before Slim\Middleware\SessionCookie?
Something like this:
require 'Slim/Slim.php';
Slim\Slim::registerAutoloader();
class CustomMiddleware extends Slim\Middleware
{
public function call() {
// This session variable should be saved
$_SESSION['test'] = 'Hello!';
$this->next->call();
}
}
$app = new Slim\Slim();
$app->add(new CustomMiddleware());
$app->add(new Slim\Middleware\SessionCookie());
// GET route
$app->get('/', function () use ($app)
{
$app->render('home.php');
});
$app->run();
And your home.php template file:
<?php echo($_SESSION['test']); ?>
For me, it works flawlessly. But if I add Slim\Middleware\SessionCookie before my CustomMiddleware, the output of $_SESSION['test'] remains NULL.
This is how middleware works:
So, your response will never get any $_SESSION value, since you set your $_SESSION before SessionCookie called.
