I am trying to send a variable that I get from an input to my controller in the following way

$(document).ready(function() {
    $(".autocomplete").on('blur',function(){
        var occ = $("#oculto_id").val();
        $.ajax({
            url: "{{ path('reg_validacion') }}",
            type: "POST",
            data: occ,
            success: function(data) {
                alert(data);
                //si hago un alert(occ); me imprime la variable,lo que significa que el input no esta en null
            }
        });
    });
});

but the alert (data) returns me:

and in the controller I'm not receiving anything.

public function validatection(Request $request)
{
    $varpost=$request->query->get("occ");

    dump($varpost);
    die();
    return $varpost;

}

Any suggestions on how I can get the occ value of the input in the controller?

The problem is in the controller, when you send the data by GET method, you receive it in this way:

$varpost=$request->query->get("occ");

And when you send the data by POST, you should receive it in this way.

$varpost=$request->request->get("occ");

You can also send it directly via the URL (GET), adjusting your url in the ajax method in this way:

url =  "{{ path('ruta_del_controlador', {'datos_envio':'x1'}) }}";
url = url.replace('x1', variable);

Problem, the OCC value is not being sent correctly,

In ajax it would be

data: {occ:occ}
// o de esta maneta
data: {occ}
// o de esta maneta
data: {"occ":occ}

Remember that you are sending by POST and in symfony the variable is obtained in this way

// parametros por $_GET
$request->query->get('occ');

// parametros por $_POST
$request->request->get('occ');

If you can not deal with these, try one of these:

$this->container->get('request_stack')->getCurrentRequest();
$this->get('request');
$request->query->get('keyWord');
$request->request->get('keyWord');
$request->get('keyWord');
$request->request->getInt('keyWord');
$request->query->all();
