Slim Framework Flash Messages

Build Status

This repository contains a Slim Framework Flash messages service provider. This enables you to define transient messages that persist only from the current request to the next request.


Via Composer

$ composer require slim/flash

Requires Slim 3.0.0 or newer.


// Start PHP session

$app = new \Slim\App();

// Fetch DI Container $container = $app->getContainer();

// Register provider $container['flash'] = function () { return new \Slim\Flash\Messages(); };

$app->get('/foo', function ($req, $res, $args) { // Set flash message for next request $this->flash->addMessage('Test', 'This is a message');

// Redirect
return $res->withStatus(302)->withHeader('Location', '/bar');


$app->get('/bar', function ($req, $res, $args) { // Get flash messages from previous request $messages = $this->flash->getMessages(); print_r($messages);

// Get the first message from a specific key
$test = $this->flash->getFirstMessage('Test');



Please note that a message could be a string, object or array. Please check what your storage can handle.

Using with Twig-View

If you use Twig-View, then slim-twig-flash may be a useful integration package.
