[Symfony][SF2][Symfony2]Ajaxowe dodawanie do bazy Opcje

[Crea17]

Witam.

Mam problem z ajaxowym dodawaniem do bazy danych. Szukałem informacji na Stackoverflow, dokumentacji i nic.

Bez ajax dodawanie działa prawidłowo (oczywiście jeżeli zakomentuje if($request->isXmlHttpRequest()).

    public function indexAction(Request $request)
    {
        $form = $this->createForm(new AddPostType(), NULL, array(
            'attr' => array('id' => 'ajax_post_add')
        ));
 
        $form->handleRequest($request);
        if($request->isXmlHttpRequest())
        {
            if ($form->isValid())
            {
                if($post = $this->addPost($form->getData()))
                {
                    $json = json_encode(
                        array(
                            'id' => $post->getId()
                        )
                    );
                    $response = new Response($json);
                    $response->headers->set('Content-Type', 'application/json');
                    return $response;
                }
            }
            $json = json_encode(
                array(
                    'error' => json_encode($request->request->get('post'))

        $offset = NULL;
        $posts = $this->getPosts(array('created' => 'DESC', 'id' => 'DESC'), $limit, $offset);
 
 
 
        return array('posts' => $posts, 'form' => $form->createView());
    }

Kod

//Template

{{ form(form) }}

<div id="post_list"></div>

<script type="text/javascript">
        $(function(){

            console.log('ready!');

            $('#ajax_post_add').find('button').click(function(e){
                console.log('clicked!');
                e.preventDefault();
                var $form = $(this).parent().find('#ajax_post_add');
                var $textarea = $form.find('textarea');
                var $url = $form.attr('action');
                var $data = $form.serialize();

                $.ajax({
                    url: $url,
                    data: $data,
                    method: 'post',
                    dataType: 'json',
                    cache: false,
                    success: function(obj){
//                        $('#post_list').prepend(obj.id);
                        alert(obj.error);
                        console.log('success');
                    },
                    complete: function(){
                        console.log('complete');
                    },
                    error: function(err){
                        console.log('error');
                        console.log(err);
//                        alert(err.error);
                    }
                });
            });

        });
    </script>

W Profilerze sprawdziłem i gdy dodaje bez ajax mam Response Content -> my_frontendbundle_addposttype%5Bcontent%5D=asdasd&my_frontendbundle_addposttype%5BOpublikuj%5D=

a z AJAX -> Request content not available (it was retrieved as a resource).

Nie mam pojęcia co z tym zrobić ;/

Do zamknięcia... Błąd był w funkcji jQuery...
