A lightweight package to flash messages

This is a lightweight package to send flash messages in Laravel apps. A flash message is a message that is carried over to the next request by storing it in the session. This package only supports one single flash message at a time.

This is how it can be used:

class MySpecialSnowflakeController
{
    public function store()
    {
        // …

        flash('My message', 'my-class');

        return back();
    }
}

In your view you can do this:

@if(flash()->message)
    <div class="{{ flash()->class }}">
        {{ flash()->message }}
    </div>
@endif

Installation

You can install the package via composer:

composer require spatie/laravel-flash

Usage

Here is an example on how to flash a message.

class MyController
{
    public function store()
    {
        // …

        flash('My message');

        return back();
    }
}

In your view you can use it like this

@if(flash()->message)
    <div>
        {{ flash()->message }}
    </div>
@endif

Using a class name to style the displayed message

You can add a class as the second parameter. This is typically used to style the output in your HTML.

class MyController
{
    public function store()
    {
        // …

        flash('My message', 'my-class'));

        return back();
    }
}

In your view you can use the class like this:

@if(flash()->message)
    <div class="{{ flash()->class }}">
        {{ flash()->message }}
    </div>
@endif

You can also set an array of classes. These will be output by flash()->class by imploding the array with a space-delimiter.

 flash('My message', ['my-class', 'another-class'])); // flash()->class output is: 'my-class another-class'

Adding your own methods

If you don't want to specify a class each time you flash a message you can add a method name to flash.

The easiest way is by passing an array to the levels method. The key is the method name that should be added to flash(). The value is the class that will automatically be used when rendering the message.

// this would probably go in a service provider

\Spatie\Flash\Flash::levels([
    'success' => 'alert-success',
    'warning' => 'alert-warning',
    'error' => 'alert-error',
]);

The above example will make these methods available on flash:

flash()->success('Hurray');
flash()->warning('Mayybeee');
flash()->error('Oh Oh');

Additionally, when you've added your own method, you can also pass that method name as a second parameter to flash itself:

flash('Hurray', 'success'); // `flash()->class` will output 'alert-success'

You can also add a method to flash by using macro.

Here's an example:

// this would probably go in a service provider

use Spatie\Flash\Message;

\Spatie\Flash\Flash::macro('warning', function(string $message) {
    return $this->flashMessage(new Message($message, 'alert alert-warning'));
});

You can now use a warning method on flash:

flash()->warning('Look above you!');

Alternatives

This package is intended to be lightweight. If you need things like multiple messages, support for Bootstrap, overlays, ... take a look at this excellent flash package by Jeffrey Way or Laraflash by Ilya Sakovich.
