Symfony logout handler

symfony

Solution

Session is destroyed on logout. But you can change this behavior by adding `invalidate_session: false` in your `security.yml` file.

logout:
    path:   /logout
    success_handler: authentication_handler
    invalidate_session: false

Check the reference documentation to have more information.

If you still want to invalidate session, you can set a flag in your Request directly and use it with a Kernel listener.

Problem

I am just trying already couple of hours to figure out how to get flash message working after logout action. security.yml ``` login: pattern: ^/login$ security: false secured_area: pattern: ^/ form_login: check_path: /check login_path: /login failure_handler: authentication_handler logout: path: /logout success_handler: authentication_handler ``` config.yml ``` services: authentication_handler: class: Project\LoginBundle\Handler\AuthenticationHandler ``` AuthenticationHandler.php ``` class AuthenticationHandler implements AuthenticationFailureHandlerInterface, LogoutSuccessHandlerInterface { public function onAuthenticationFailure(Request $request, AuthenticationException $exception) { $referer = $request->headers->get('referer'); $request->getSession()->setFlash('error', $exception->getMessage()); return new RedirectResponse($referer); } public function onLogoutSuccess(Request $request) { $referer = $request->headers->get('referer'); $request->getSession()->setFlash('success', 'Wylogowano'); return new RedirectResponse($referer); } } ``` view hello after login ``` {% extends "ProjectCMSBundle:Secured:layout.html.twig" %} {% block title "Hello " ~ name %} {% block content %} <h1>Hello {{ name }}!</h1> <a href="{{ path('_project_secured_hello_admin', { 'name': name }) }}">Hello resource secured for <strong>admin</strong> only.</a> {% endblock %} {% set code = code(_self) %} ``` view login form ``` {% extends 'ProjectCMSBundle::layout.html.twig' %} {% block title %} Title {% endblock %} {% block content %} <form action="{{ path("_project_security_check") }}" method="post" id="login"> <div class="data"> <div class="username"> <label for="username">&nbsp;</label> <input type="text" id="username" name="_username" value="{{ last_username }}" /> </div> <div class="password"> <label for="password">&nbsp;</label> <input type="password" id="password" name="_password" /> </div> </div> {% if error %} <div class="error">{{ error.message|trans({},'messages') }}</div> {% endif %} <input type="submit" class="submit" /> </form> {% endblock %} {% set code = code(_self) %} ``` layout main template ``` <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <link rel="stylesheet" href="{{ asset('bundles/project/css/demo.css') }}" type="text/css" media="all" /> <title>{% block title %}{% endblock %}</title> <link rel="shortcut icon" href="{{ asset('favicon.ico') }}" /> </head> <body> <div id="symfony-wrapper"> {% if app.session.flash('error') %} <div class="flash-message"> {{ app.session.flash('error')|trans }} </div> {% endif %} {% if app.session.flash('success') %} <div class="flash-message"> {{ app.session.flash('success')}} </div> {% endif %} {% if app.user %} {% block content_header %} <ul id="menu"> {% block content_header_more %} {% endblock %} </ul> <div style="clear: both"></div> {% endblock %} {% endif %} <div class="symfony-content"> {% block content %} {% endblock %} </div> {#{% if code is defined %} <h2>Code behind this page</h2> <div class="symfony-content">{{ code|raw }}</div> {% endif %}#} </div> </body> ``` The problem is that it seems that flash message is getting dropped during redirect. Is there any way to accomplish this? Thanks for the answers.
