What am I doing wrong when I install dropzone programmatically?

Question

JavaScript

<div id="dropZed" class="dropzone"></div>

js скрипт в самом конце файла
<script>
        var dzone = new Dropzone("#dropZed", {
            paramName: "img_url",
            url: "/admin/MyGallery/create",
            method: "files"
        });
        Dropzone.autoDiscover = false;
    </script>

php обработчик
if(isset($_POST['submit'])){
            print_r($_FILES['img_url']);
        }

But I have
Undefined index: img_url; Why did I specify both the method and the parameter in js, the url checked everything correctly.
