Easy Flash Messages for Your Laravel App for Bootstrap 4

Installation

First, pull in the package through Composer.

Run composer require laracasts/flash

And then, if using Laravel 5, include the service provider within config/app.php.

'providers' => [
    Laracasts\Flash\FlashServiceProvider::class,
];

Usage

Within your controllers, before you perform a redirect...

public function store()
{
    flash('Welcome Aboard!');

    return home();
}

You may also do:

  • flash('Message', 'title', 'info')
  • flash('Message', 'title', 'success')
  • flash('Message', 'title', 'danger')
  • flash('Message', 'title', 'warning')
  • flash()->overlay('Modal Message', 'Modal Title')
  • flash('Message', 'title')->important()

Behind the scenes, this will set a few keys in the session:

  • 'flash_notification.message' - The message you're flashing
  • 'flash_notification.title' - The title you're flashing
  • 'flash_notification.level' - A string that represents the type of notification (good for applying HTML class names)

With this message flashed to the session, you may now display it in your view(s). Maybe something like:

@if (session()->has('flash_notification.message'))
    <div class="alert alert-{{ session('flash_notification.level') }}">
        <button type="button" class="close" data-dismiss="alert" aria-hidden="true">&times;</button>

        {!! session('flash_notification.message') !!}
    </div>
@endif

Note that this package is optimized for use with Twitter Bootstrap.

Because flash messages and overlays are so common, if you want, you may use (or modify) the views that are included with this package. Simply append to your layout view:

@include('flash::message')

Example

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
</head>
<body>

<div class="container">
    @include('flash::message')

    <p>Welcome to my website...</p>
</div>

<!-- This is only necessary if you do Flash::overlay('...') -->
<script src="//code.jquery.com/jquery.js"></script>
<script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

<script>
    $('#flash-overlay-modal').modal();
</script>

</body>
</html>

If you need to modify the flash message partials, you can run:

php artisan vendor:publish

The two package views will now be located in the app/views/packages/laracasts/flash/ directory.

flash('Welcome Aboard!');

return home();

flash('Sorry! Please try again.', 'danger');

return home();

https://dl.dropboxusercontent.com/u/774859/GitHub-Repos/flash/error.png

flash()->overlay('Notice', 'You are now a Laracasts member!');

return home();

Hiding Flash Messages

A common desire is to display a flash message for a few seconds, and then hide it. To handle this, write a simple bit of JavaScript. For example, using jQuery, you might add the following snippet just before the closing </body> tag.

<script>
$('div.alert').not('.alert-important').delay(3000).fadeOut(350);
</script>

This will find any alerts - excluding the important ones, which should remain until manually closed by the user - wait three seconds, and then fade them out.
