In Laravel, the best way to pass different types of flash messages in the session

Question

I\'m making my first app in Laravel and am trying to get my head around the session flash messages. As far as I\'m aware in my controller action I can set a flash message ei

Answer 1

For my application i made a helper function:

function message( $message , $status = 'success', $redirectPath = null )
{
     $redirectPath = $redirectPath == null ? back() : redirect( $redirectPath );

     return $redirectPath->with([
         'message'   =>  $message,
         'status'    =>  $status,
    ]);
}

message layout, main.layouts.message:

@if($status)
   <div class="center-block affix alert alert-{{$status}}">
     <i class="fa fa-{{ $status == 'success' ? 'check' : $status}}"></i>
     <span>
        {{ $message }}
     </span>
   </div>
@endif

and import every where to show message:

@include('main.layouts.message', [
    'status'    =>  session('status'),
    'message'   =>  session('message'),
])

In your view:

<div class="flash-message">
  @foreach (['danger', 'warning', 'success', 'info'] as $msg)
    @if(Session::has('alert-' . $msg))
    <p class="alert alert-{{ $msg }}">{{ Session::get('alert-' . $msg) }}</p>
    @endif
  @endforeach
</div>

Then set a flash message in the controller:

Session::flash('alert-danger', 'danger');
Session::flash('alert-warning', 'warning');
Session::flash('alert-success', 'success');
Session::flash('alert-info', 'info');

Simply return with the 'flag' that you want to be treated without using any additional user function. The Controller:

return \Redirect::back()->withSuccess( 'Message you want show in View' );

Notice that I used the 'Success' flag.

The View:

@if( Session::has( 'success' ))
     {{ Session::get( 'success' ) }}
@elseif( Session::has( 'warning' ))
     {{ Session::get( 'warning' ) }} <!-- here to 'withWarning()' -->
@endif

Yes, it really works!

Answer 4

Another solution would be to create a helper class How to Create helper classes here

class Helper{
     public static function format_message($message,$type)
    {
         return '<p class="alert alert-'.$type.'">'.$message.'</p>'
    }
}

Then you can do this.

Redirect::to('users/login')->with('message', Helper::format_message('A bla blah occured','error'));

or

Redirect::to('users/login')->with('message', Helper::format_message('Thanks for registering!','info'));

and in your view

@if(Session::has('message'))
    {{Session::get('message')}}
@endif

I think the following would work well with lesser line of codes.

        session()->flash('toast', [
        'status' => 'success', 
        'body' => 'Body',
        'topic' => 'Success']
    );

I'm using a toaster package, but you can have something like this in your view.

             toastr.{{session('toast.status')}}(
              '{{session('toast.body')}}', 
              '{{session('toast.topic')}}'
             );

You can make a multiple messages and with different types. Follow these steps below:

1. Create a file: "app/Components/FlashMessages.php"

namespace App\Components;

trait FlashMessages
{
  protected static function message($level = 'info', $message = null)
  {
      if (session()->has('messages')) {
          $messages = session()->pull('messages');
      }

      $messages[] = $message = ['level' => $level, 'message' => $message];

      session()->flash('messages', $messages);

      return $message;
  }

  protected static function messages()
  {
      return self::hasMessages() ? session()->pull('messages') : [];
  }

  protected static function hasMessages()
  {
      return session()->has('messages');
  }

  protected static function success($message)
  {
      return self::message('success', $message);
  }

  protected static function info($message)
  {
      return self::message('info', $message);
  }

  protected static function warning($message)
  {
      return self::message('warning', $message);
  }

  protected static function danger($message)
  {
      return self::message('danger', $message);
  }
}

2. On your base controller "app/Http/Controllers/Controller.php".

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesResources;

use App\Components\FlashMessages;

class Controller extends BaseController
{
    use AuthorizesRequests, AuthorizesResources, DispatchesJobs, ValidatesRequests;

    use FlashMessages;
}

This will make the FlashMessages trait available to all controllers that extending this class.

3. Create a blade template for our messages: "views/partials/messages.blade.php"

@if (count($messages))
<div class="row">
  <div class="col-md-12">
  @foreach ($messages as $message)
      <div class="alert alert-{{ $message['level'] }}">{!! $message['message'] !!}</div>
  @endforeach
  </div>
</div>
@endif

4. On "boot()" method of "app/Providers/AppServiceProvider.php":

namespace App\Providers;

use Illuminate\Support\ServiceProvider; 

use App\Components\FlashMessages;

class AppServiceProvider extends ServiceProvider
{
  use FlashMessages;

    public function boot()
    {
        view()->composer('partials.messages', function ($view) {

          $messages = self::messages();

          return $view->with('messages', $messages);
      });
    }

    ...
}

This will make the $messages variable available to "views/partials/message.blade.php" template whenever it is called.

5. On your template, include our messages template - "views/partials/messages.blade.php"

<div class="row">
  <p>Page title goes here</p>
</div>

@include ('partials.messages')

<div class="row">
  <div class="col-md-12">
      Page content goes here
  </div>
</div>

You only need to include the messages template wherever you want to display the messages on your page.

6. On your controller, you can simply do this to push flash messages:

use App\Components\FlashMessages;

class ProductsController {

  use FlashMessages;

  public function store(Request $request)
  {
      self::message('info', 'Just a plain message.');
      self::message('success', 'Item has been added.');
      self::message('warning', 'Service is currently under maintenance.');
      self::message('danger', 'An unknown error occured.');

      //or

      self::info('Just a plain message.');
      self::success('Item has been added.');
      self::warning('Service is currently under maintenance.');
      self::danger('An unknown error occured.');
  }

  ...

Hope it'l help you.
