[FIXED] How to test if a session already exists?

Issue

How can I test if a session exists in symfony?

Without the framework we proceed like this:

<?php

if( isset($_SESSION['login'])) {
  echo 'Bonjour '.$_SESSION['login'].' vous etes connecté.<br>';
}

?>

How to do so with the session service in the symfony controller with the Request object?

Solution

In Symfony, session service is an instance of Symfony\Component\HttpFoundation\Session\Session. That said, session does provide several method to either check or manipulate session.

In your particular case, you would do something like this:

$session = $request->getSession();

if ( $session->has('login')){
    $message = 'Bonjour '.$session->get('login').' vous etes connecté.<br>';
}

But, noting the comment from @Gerry, his question is a very valid one.

Hope this helps...
