README

The package helps in working with sessions in a PSR-7/PSR-15 environment.

It also provides a flash message service which helps use one-time messages.

Requirements

PHP 8.2 or higher.

Installation

composer require stefna/session

Session

In order to maintain a session between requests you need to add SessionMiddleware to middleware collection.

Then you will have access to the session storage in the request object and can be retrieved

<?php
$session = $request->getAttribute(\Stefna\Session\SessionStorage::class); 

Flash Messages

You need to add FlashMiddleware to your middleware runner, and it needs to be added after the SessionMiddleware.

Then you will have access to the flash messages in the request object and can be retried

<?php
$messageCollection = $request->getAttribute(\Stefna\Session\Flash\FlashMessages::class); 

Concept

The main concept of package is the separation of using the session from persisting the session.

This is achieved with lazy loading everything. The session is not started until someone needs something from the session.

Usage of session

<?php
use Psr\Http\Message\ServerRequestInterface;

class Action
{
	public function __invoke(ServerRequestInterface $request)
	{
		$session = $request->getAttribute(\Stefna\Session\SessionStorage::class);
		if ($session->getBool('loggedIn')) {
			$session->set('loggedIn', false);
		}
		elseif ($session->has('blocked')) {
			$session->remove('blocked');
		}
	}
}

Usage of flash messages

Add flash messages

<?php
use Psr\Http\Message\ServerRequestInterface;
use Stefna\Session\Flash\FlashMessage;
use Stefna\Session\Flash\FlashMessages;
use Stefna\Session\Flash\MessageType;

class Action
{
	public function __invoke(ServerRequestInterface $request)
	{
		$flashMessages = $request->getAttribute(FlashMessages::class);
		$flashMessages->add(new FlashMessage('Stuff happened', type: MessageType::Live));
	}
}

Get flash messages

Getting the flash messages means that they will be removed from storage.

<?php
use Psr\Http\Message\ServerRequestInterface;
use Stefna\Session\Flash\FlashMessages;
use Stefna\Session\Flash\MessageType;

class Action
{
	public function __invoke(ServerRequestInterface $request)
	{
		$flashMessages = $request->getAttribute(FlashMessages::class);
		$messages = $flashMessages->getMessages(MessageType::Live);
		
		$this->renderGrowMessages($messages);
	}
}
