A simple package to allow usage of flash messages using session. Totaly framework and template agnostic.

Install

To install this package

composer require ajani/flash-message

Usage

FlashMessage is KISS oriented. It only offer two major functionnalities :

• Writing a new flash message in session.
• Reading and remove a flash message from session.

To use FlashMessage, include autoload.php from Composer, and use use \FlashMessage\FlashMessage. No need to instanciate class FlashMessage as it's a static class.

Make sure you have enabled session before using FlashMessage or nothing will happen

Store a flash message :

When you want to store a flash message, call the method push($type, $text) and pass it the $type of the message (usually a short string, like error, info, success or danger) and the $text of the message.

<?php
	session_start();
	include('./vendor/autoload.php');
	\FlashMessage\FlashMessage::push('success', 'Congrats, you\'ve just write a message !');

Retrieve a stored message :

When you want to retrieve a previously stored message, you can call two different functions :

• next() to return next unread message and remove it from session.
• next_type($type) to return next unread message of a specific type and remove it from session.

<?php
	session_start();
	include('./vendor/autoload.php');

	while ($message = \FlashMessage\FlashMessage::next())
	{
		echo "Find a flash message.";
		echo "Message type: " . $message['type'];
		echo "Message: " . $message['text'];
	}

Count unread messages

You can count unread messages at any time by calling count() method.

<?php
	session_start();
	include('./vendor/autoload.php');

	echo "You have " . \FlashMessage\FlashMessage::count() . " unread messages.";
