Laravel 4 Flash Notifications
, (*1)
A simple and easy to use flash notification setup for Laravel 4., (*2)
Extension
By default, the notifications are handled by the Illuminate Session Store but this can be easily replaced by implementing the Jralph\Notification\Contracts\Store contract provided and then bound using the IoC container. Once done, any existing code will continue to work as normal. For example, you could easily switch out the Session Store for your own form of storage for flash messages., (*3)
Usage
Laravel
To use the Notification in Laravel, you can add the service provider and alias to your app/config/app.php file., (*4)
<?php
...
'providers' => array(
...
'Jralph\Notification\NotificationServiceProvider',
...
),
...
'aliases' => array(
...
'Notification' => 'Jralph\Notification\Facades\Notification'
...
),
...
?>
Once this is done, you can use the facade like so., (*5)
<?php
Notification::put('key', 'value');
?>
See below for more information on the methods the class provides., (*6)
Methods
PUT, (*7)
The put method flashes a key => value message to the session., (*8)
<?php
Notification::put('key', 'value');
?>
GET, (*9)
The get method retrieves a value from the session by key., (*10)
<?php
Notification::get('key'); // If using the above put somewhere, this will return (string) 'value'.
?>
HAS, (*11)
The has method checks if a key exists in the notification session storage., (*12)
<?php
Notification::has('key',); // If using the above put somewhere, this will return true.
?>
TAGS, (*13)
The tags method can be combined with the put method to tag specific notifications., (*14)
<?php
Notification::tags(['tag1', 'tag2'])->put('key', 'value');
?>
TAG, (*15)
The tag method is used to retrieve an array of notifications attached to a specific tag., (*16)
<?php
Notification::tag('tag1'); // Returns an array of all notifications tagged as `tag1`.
?>
Example Usage
In a controller processing login somewhere., (*17)
fails())
{
Notification::tags(['error'])->put('validation_failed', 'The form validation has failed.'); // Note you could pass an array as the value.
return Redirect::back();
}
// Process User Login
}
}
?>
Somewhere in a view displaying the login form somewhere., (*18)
@foreach (Notification::tag('error') as $key => $notification)
<div class="notification">
<strong>{{ $key }}</strong> {{ $notification }}
</div>
@endforeach
You could also disregard the tags for a simpler approach and just display the validation failed error., (*19)
@if (Notification::has('validation_failed'))
<div class="notification">
<strong>Validation Failed</strong> {{ Notification::get('validation_failed') }}
</div>
@endif
Upcoming Features
- Add a default tag that is not overwritten.
-
OR add the
Notification::all() method to retrieve all messages.
