The page is not redirecting after the contact details were put and it also is not sending an email

I can not find my coding mistake.

<?php require 'vendor/autoload.php'; date_default_timezone_set('Asia/Tel_Aviv');

//$log = new Logger('name'); //$log->pushHandler(new StreamHandler('app.txt', Monolog\Logger::WARNING)); //$log->addWarning('Foo');

$app = new \Slim\Slim( array( 'view' => new \Slim\Views\Twig() ));

$view = $app->view(); $view->parserOptions = array( 'debug' => true );

$view->parserExtensions = array( new \Slim\Views\TwigExtension(), );

$app->get('/', function() use($app){ $app->render('about.twig'); });

$app->get('/contact', function() use($app){ $app->render('contact.twig'); });

$app->post('/contact', function() use($app){ $name = $app->request->post('name'); $email = $app->request->post('email'); $msg = $app->request->post('msg');

if(!empty($name) && !empty($email) && !empty($msg)){ $cleanName = filter_var($name, FILTER_SANITIZE_STRING); $cleanEmail = filter_var($email, FILTER_SANITIZE_EMAIL); $cleanMsg = filter_var($msg, FILTER_SANITIZE_STRING); } else { //msg the user there is a problem. $app->redirect('/contact'); }

$transport = Swift_SendmailTransport::newInstance('/usr/sbin/sendmail -bs'); $mailer = \Swift_Mailer::newInstance($transport);

$message = \Swift_Message::newInsntace(); $message->setSubject('Email From Our Website'); $message->setFrom(array( $cleanEmail => $cleanName )); $message->setTo(array('treehouse@localhost')); $message->setBody($cleanMsg);

$result = $mailer->send($message);

if($result > 0){ // send a message to the user thank you. $app->redirect('/'); } else { //send a message to the user the message failed. //log that there was an error. $app->redirect('/contact'); } });

$app->run();
