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

I usually do this

in my store() function i put success alert once it saved properly.

\Session::flash('flash_message','Office successfully updated.');

in my destroy() function, I wanted to color the alert red so to notify that its deleted

\Session::flash('flash_message_delete','Office successfully deleted.');

Notice, we create two alerts with different flash names.

And in my view, I will add condtion to when the right time the specific alert will be called

@if(Session::has('flash_message'))
    <div class="alert alert-success"><span class="glyphicon glyphicon-ok"></span><em> {!! session('flash_message') !!}</em></div>
@endif
@if(Session::has('flash_message_delete'))
    <div class="alert alert-danger"><span class="glyphicon glyphicon-ok"></span><em> {!! session('flash_message_delete') !!}</em></div>
@endif

One solution would be to flash two variables into the session:

1. The message itself
2. The "class" of your alert

for example:

Session::flash('message', 'This is a message!'); 
Session::flash('alert-class', 'alert-danger'); 

Then in your view:

@if(Session::has('message'))
<p class="alert {{ Session::get('alert-class', 'alert-info') }}">{{ Session::get('message') }}</p>
@endif

Note I've put a default value into the Session::get(). that way you only need to override it if the warning should be something other than the alert-info class.

(that is a quick example, and untested :) )

If you want to use Bootstrap Alert to make your view more interactive. You can do something like this:

In your function:-

if($author->save()){
    Session::flash('message', 'Author has been successfully added');
    Session::flash('class', 'success'); //you can replace success by [info,warning,danger]
    return redirect('main/successlogin');

In your views:-

@if(Session::has('message'))
    <div class="alert alert-{{Session::get('class')}} alert-dismissible fade show w-50 ml-auto alert-custom"
        role="alert">
        {{ Session::get('message') }}
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
@endif

My way is to always Redirect::back() or Redirect::to():

Redirect::back()->with('message', 'error|There was an error...');

Redirect::back()->with('message', 'message|Record updated.');

Redirect::to('/')->with('message', 'success|Record updated.');

I have a helper function to make it work for me, usually this is in a separate service:

function displayAlert()
{
      if (Session::has('message'))
      {
         list($type, $message) = explode('|', Session::get('message'));

         $type = $type == 'error' : 'danger';
         $type = $type == 'message' : 'info';

         return sprintf('<div class="alert alert-%s">%s</div>', $type, message);
      }

      return '';
}

And in my view or layout I just do

{{ displayAlert() }}
