Stack/Session

Session stack middleware.

Enables the request session for subsequent middlewares.

Example

Here's an example giving a silex app access to the session using stack/stack:

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\RedirectResponse;

$app = new Silex\Application();

$app->get('/login', function (Request $request) {
    $session = $request->getSession();

    $username = $request->server->get('PHP_AUTH_USER');
    $password = $request->server->get('PHP_AUTH_PW');

    if ('igor' === $username && 'password' === $password) {
        $session->set('user', array('username' => $username));
        return new RedirectResponse('/account');
    }

    return new Response('Please sign in.', 401, [
        'WWW-Authenticate' => sprintf('Basic realm="%s"', 'site_login'),
    ]);
});

$app->get('/account', function (Request $request) {
    $session = $request->getSession();

    if (null === $user = $session->get('user')) {
        return new RedirectResponse('/login');
    }

    return sprintf('Welcome %s!', $user['username']);
});

$stack = (new Stack\Builder())
    ->push('Stack\Session');

$app = $stack->resolve($app);

Options

The following options can be used to configure stack/session:

session.storage.save_path (optional): The path for the NativeFileSessionHandler, defaults to the value of sys_get_temp_dir().
session.storage.options (optional): An array of options that is passed to the constructor of the session.storage service.

In case of the default NativeSessionStorage, the possible options are listed on the PHP manual's session configuration page.
session.default_locale (optional): The default locale, defaults to en.
session.cookie_params (optional): Override parameter values for the session cookie as listed on the PHP manual's session_get_cookie_params page. (allowed keys: lifetime, path, domain, secure, and httponly)

Usage

The session middleware enables the Session object on the request. You can access it through the Request object:

$session = $request->getSession();

$session->start();
$foo = $session->get('foo');
$session->set('foo', 'bar');

Silex SessionServiceProvider

Note that this middleware is a replacement for the silex SessionServiceProvider. If you want to use it with silex, you might want to define the session service as follows:

$app['session'] = $app->share(function ($app) {
    return $app['request']->getSession();
});

This is only needed if you have services that depend on the session service.

Inspiration

This middleware is based on the silex SessionServiceProvider.
