Send data to Symfony2 controller with Ajax Post

Question

If someone plays a YouTube video I want to send this information to a Symfony Controller. But somehow the controller receives nothing.

The Ajax Post

 // Check if video is playing (works)
  var myPlayerState;
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING) {
        alert('playing');

         $.ajax({
              url: "{{ path('dbe_user_add_experience') }}",
              type: "POST",
              data: { "data" : 'test' },
              success: function(data) { 
                 alert (data);
              },
              error: function(XMLHttpRequest, textStatus, errorThrown)
              {
                alert('Error: ' +  errorThrown);
              }
           });
    }
    myPlayerState = event.data;
  }

The Routing

<route id="dbe_user_add_experience" pattern="/getexperience">
    <default key="_controller">FOSUserBundle:Level:getExperience</default>
</route>

The Controller

  public function getExperienceAction(){
        $request = $this->container->get('request');
        $data = $request->request->get('data');
        var_dump($data);
        die;


        $url = $this->container->get('router')->generate('fos_user_profile_show');
        $response = new RedirectResponse($url);
        return $response;

        //$this->addExperience(5);
  }

One thing is that you are using POST/->request and then checking the GET/->query part of the request. — qooplmao

okay, I fixed that. but I think somehow it's not sending the information at all. I checked with firebug > Networkanalysis and there is no POST method visible after the click. — Steinbock

Instead of

$data = $request->query->get('data');

Use

$data = $request->get('data');

Okay, I fixed that part. But somehow I still don't see a POST method in the firebug networkanalysis.

do you get any javascript errors? is alert executed? is url properly parsed by twig?

Steinbock Over a year ago

Yes the alert is executed. How can I check if the url is properly parsed? I'm not sure if the ajax post is executed at all? I get one error message in the console: TypeError: $ is undefined

Try to use getexperience path hardcoded instead of path expression or check javascript code at your browser side, check javascript source if url is properly set

If you have $ is undefined it means that you don't have jQuery loaded, which means your ajax call can't be executed

You are using the wrong property to get POST data.

To get GET data :

$request->query->get('data');

To get POST data :

$request->request->get('data');

I found the error: Ajax was in the noconflict modus. Meaning I had to change $.ajax({ to jQuery.ajax({.
