Symfony2 - Sending other data along with form data via Ajax causes IsValid() to return false

Question

I'm trying to send other data along with a submitted form to a controller inside Symfony2.

When I try this like:

$("#submit_btn").on("click", function(e){
        e.preventDefault();
        $.ajax({
            type: "POST",
            url: post_url,
            data: form.serialize()
        });
    });

I see i got a successful POST request followed by a redirect as intended inside the controller action, If IsValid() returned true.

But when I try to send other data with the form like:

$("#submit_btn").on("click", function(e){
        e.preventDefault();
        $.ajax({
            type: "POST",
            url: post_url,
            data: { form: form.serialize(), otherdata: "test" }
        });
    });

I do not get the redirection 302 response. instead I get only one 200 response when means IsValid() method returned false. My question here how to not only send form, but also other data with it ?

Here's my controller action:

public function postOverviewAction(Request $request, $id)
    {
        $overview = $this->get("doctrine_mongodb")->getRepository("GbrBEBundle:Overview")->findOneById($id);
        $overview_photos = $this->get("doctrine_mongodb")->getRepository("GbrBEBundle:OverviewPhoto")->findAll();
        $form = $this->createForm(new OverviewType(), $overview);
        $form->handleRequest($request);

        $height = $form->get("coordinate_height")->getData();
        $width = $form->get("coordinate_width")->getData();
        $x = $form->get("coordinate_x")->getData();
        $y = $form->get("coordinate_y")->getData();

        if($form->isValid())
        {
            $overview->setCropCoordinates(array('height' => $height, 'width' => $width, 'x' => $x, 'y' => $y));
            $dm = $this->get("doctrine_mongodb")->getManager();
            $dm->persist($overview);
            $dm->flush();
            return $this->redirect($this->generateUrl("gbr_be_get_overview"));
        }
        return $this->render("GbrBEBundle:Default:overview.html.twig", array(
            "form" => $form->createView(),
            "overview" => $overview,
            "overview_photos" => $overview_photos,
        ));
    }

You can add an unmapped field to the form:

How do I add an unbound field to a form in Symfony which is otherwise bound to an entity?

Setting to type text should prove the most versatile.

You can also create a collection field as the unmapped field, and assign the text type to it. This will allow you to have multiple additional text data on the receiving end.

First, Thanks for your answer. My problem is not with the unmapped fields. It's with sending a request that not only include the form data but also other variables set inside jquery. Symfony have some mechanism on calling `IsValid()` method. So apparently it thinks that the form is not posted at all, While in fact it's posted with other variables inside a collection created in jQuery. – Rafael Adel Dec 11 '13 at 08:38
Are you also sending the token? – Flosculus Dec 11 '13 at 08:43

may be try to change:

 data: { form: form.serialize(), otherdata: "test" }

by data: form.serialize()+'&otherdata=test',

i think its because .serialize() return a string.
