Installation

composer require k-ko/slim3-session-middleware

Usage

<?php

$app = new \Slim\App();

$app->get('/', function (Request $request, Response $response) use ($container) {
    if (!isset($container['session']['loggedIn'])) {
        // ...
    }
    // ...
});

// Add as LAST middleware to run 1st
$app->add(new \Middleware\SessionMiddleware([
    'autorefresh'   => true,
    'name'          => 'myapp_session',
    'lifetime'      => '1 hour',
    // optional:
    'handler' => new \Session\MySQLiSessionHandler($container['mysqli'])
]));

$app->run();

Supported Options

Option	Type	Default	Description
`autorefresh`	boolean	`false`	If you want session to be refresh when user activity is made (interaction with server).
`domain`	tring	`null`	Cookie domain, for example 'www.php.net'. To make cookies visible on all subdomains then the domain must be prefixed with a dot like '.php.net'.
`handler`	mixed	`null`	Custom session handler class or object. Must implement `SessionHandlerInterface` as required by PHP.
`httponly`	boolean	`false`	If set to true then PHP will attempt to send the httponly flag when setting the session cookie.
`ini_settings`	array	`null`	Associative array of custom session configuration.
`lifetime`	int or string	`"20 minutes"`	The lifetime of the session cookie. Can be set to any value which `strtotime` can parse.
`name`	string	`"session"`	Name for the session cookie. Defaults to `session` instead of PHP's `PHPSESSID`.
`path`	string	`"/"`	The path on the domain where the cookie will work. Use a single slash ('/') for all paths on the domain.
`secure`	boolean	`false`	Cookies will only be sent over secure connections if true.

Session Helper

The \Session\Helper class can be attached to your app container:

$container = $app->getContainer();

$container['session'] = function ($container) {
    return new \Session\Helper();
};

The helper class can be used to check if a session variable exists in addition to setting, getting and deleting session variables.

$app->get('/', function (Request $request, Response $response) use ($container) {
    // Check if variable exists
    $exists = $container['session']->has('my_key');
    $exists = isset($container['session']->my_key);
    $exists = isset($container['session']['my_key']);

    // Get variable value
    $value = $container['session']->get('my_key', 'default');
    $value = $container['session']->my_key;
    $value = $container['session']['my_key'];

    // Take variable value out from session
    $value = $container['session']->take('my_key', 'default');

    // Set variable value
    $container['session']->set('my_key', 'my_value');
    $container['session']->my_key = 'my_value';
    $container['session']['my_key'] = 'my_value';

    // Remove variable
    $container['session']->remove('my_key');
    unset($container['session']->my_key);
    unset($container['session']['my_key']);
});
