How to Install

FlashMessages is ready to be used in any PHP project. You can install it via Composer, the PHP dependency manager. If you're not using Composer yet, it’s time to start!

Install via Composer:

Run this command in your project’s root directory:

composer require nassiry/flash-messages

Default Usage

require __DIR__ . '/vendor/autoload.php';

use Nassiry\FlashMessages\FlashMessages;

// Create an instance
$flash = FlashMessages::create();

// Standard messages
$flash->success('Operation completed successfully.');
$flash->error('Something went wrong!');
$flash->info('Here is some useful information.');
$flash->warning('Be cautious about this!');

// Custom message type
$flash->addCustomType('notification', 'This is a custom notification!', true);
$flash->addCustomType('success-green', 'This is a green-themed success message!', false);


// Render messages on the next page template file
$flash->render();

This will output HTML for each message added, like this:

<div>




<hr>

<h3>
  
  
  Instant vs. Persistent Messages
</h3>

<p>You can control whether a message is shown immediately or stored for the next page load using the $instant parameter.</p>

<ul>
<li>
<strong>Instant Message</strong>: Use $instant = true to display the message on the current page.</li>
<li>
<strong>Persistent Message</strong>: Use $instant = false to store the message in the session, to be rendered on the next page load default is false.
</li>
</ul>

<pre class="brush:php;toolbar:false">// Shown immediately
$flash->success('This is an instant success message!', true);  
// Stored for next page
$flash->error('This error will be shown on the next page.', false);
