I have a HTML form on my CakePHP application that passes a variable that is usually over 30 characters long through to my new Symfony2 application. I'm able to pass the variable from the form to Symfony without issue. However, when I echo the variable that's been passed to Symfony the variable only seems to contain just the first character of the 30/40 character sequence.

The variable is usually like this: T2psbWFGWjNXbTRob3p0VGEwVENheVZvTVRSRFRVUnFLMDVmYVhnaU5ucFJNVWgzZVZSUlRXOXI=

The HTML form used by CakePHP is like this:

<form id="TestForm" method="POST" action="/web/app_dev.php/instructors/passport/" name="input">
<input type="text" value="UkVsS1JtMW1VRFZvT21raU1HVXJVQ3RaTVRSS2JVd3JWRjVxVEdnbVZEUkZiakZsV2pjemNVWTM=" name="value">
<input type="submit" value="Go to the New Database">
</form>

The Symfony2 code is like this:

public function passportAction(Request $request)
{
    $passport = $this->getRequest()->get("value");

    // Get variables from the search form
    $value = $passport['value'];

    $session = new Session();
    $session->start();

    $session->set('passport', $value);
    $sessionval = $session->get('passport');

    print_r($sessionval);

    return $this->render('DatabaseBundle:Default:test.html.twig', array(
        'pagename' => 'Database Does Not Exist',
        'branchname' => 'Test Branch',
        'group' => '0',
        'something' => $sessionval
    ));
}

With this code, and using that variable, in Symfony2 the only thing that is displayed when the variable is echoed is T. What is going on?

Your bug comes from the fact that when you wrote : 

$passport = $this->getRequest()->get("value");

$passport already contains your variable as a string, but a string is nothing more than a pseudo array of characters. Then, later on your code, you ask for $passport['value'] and php is not bothered that you use [] on a string because it thinks you are trying to access one character from the whole string. To finish, maybe the trickiest part, where I might be wrong on explaining. You are trying to access to the value pointed by 'value' key, in fact 'value' key does not exist but I think a cast is done by php here, and it is resolved as the value 0.

try this $this->getRequest()->get("TestForm")['value']
