Laravel Session Flash persists for 2 requests

Question

Recently I have changed to Laravel from Codeigniter, everything was going fine except I encountered a problem with Session::flash.

when I create new user I get success message but It will persist for 2 requests, even I didn't pass the validator:

my code in UsersController:

function getCreateUser(){     $config = array(         'pageName' => 'createUser',         'pageTitle' => 'Create User',         'formUrl'   => action('UsersController@postCreateUser'),         'modelFields'   => array(             array('db_name' => 'employee_id', 'text' => 'Employee Id', 'mandatory' => TRUE),             array('db_name' => 'full_name', 'text' => 'Full Name', 'mandatory' => TRUE),             array('db_name' => 'email', 'text' => 'Email', 'mandatory' => FALSE),             array('db_name' => 'password', 'text' => 'Password','value' => '12345', 'mandatory' => TRUE)             ),         'submit_text' => 'Create'         );     return View::make('layouts.form', $config); }  function postCreateUser(){     $config = array(         'pageName' => 'createUser',         'pageTitle' => 'Create User',         'formUrl'   => action('UsersController@postCreateUser'),         'modelFields'   => array(             array('db_name' => 'employee_id', 'text' => 'Employee Id', 'mandatory' => TRUE),             array('db_name' => 'full_name', 'text' => 'Full Name', 'mandatory' => TRUE),             array('db_name' => 'email', 'text' => 'Email', 'mandatory' => FALSE),             array('db_name' => 'password', 'text' => 'Password','value' => '12345', 'mandatory' => TRUE)             ),         'submit_text' => 'Create'         );     $validator = User::validate(Input::all());     if($validator->passes()){         $user = new User(Input::all());         $user->password = Hash::make(Input::get('password'));         $user->Company_id = '1';         $user->save();          Session::flash('message', 'User Created Successfully!');          Session::flash('alert-class', 'alert-success');         return View::make('layouts.form', $config);     }       return View::make('layouts.form', $config)->withErrors($validator->messages()); } 

in form.blade:

@if ( $errors->count() > 0 ) <div class="alert alert-danger">     <p>The following errors have occurred:</p>      <ul>         @foreach( $errors->all() as $message )         <li>{{ $message }}</li>         @endforeach     </ul> </div> @endif 

in master.blade:

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

Maybe I'm not alone with this issue, here is another unanswered question.

Update

For anyone in future facing this problem: Never flash session data without redirecting.

My code now looks like this:

function postCreateUser(){     $validator = User::validate(Input::all());     if($validator->passes()){         $user = new User(Input::all());         $user->password = Hash::make(Input::get('password'));         $user->Company_id = '1';         $user->save();          Session::flash('message', 'User Created Successfully!');          Session::flash('alert-class', 'alert-success');     } else {         Session::flash('message', Helpers::formatErrors($validator->messages()->all()));         Session::flash('alert-class', 'alert-danger');     }      return Redirect::action('UsersController@getCreateUser'); } 

Answer 1

You are Flashing session data and creating a view instead of redirecting, meaning the message will Flash for this request and for the next one, showing twice.

If you want to show the message on the current request without redirecting, I would suggest providing the errors to your View::make instead of trying to Flash the messages. If you MUST Flash the message on the current request, then you will need to Session::forget('key') or Session::flush() after your view.

Answer 2

The following seems to be available from version 5.1 onward. Although the method is not mentioned on Laravel's documentation page about sessions.

session()->now() 

This is the same as flash, except it won't persist to the next request.
