laravel + dropzone file not uploading
<p>Why is it the file i upload not reflecting on the request even though the file is uploaded successfully?</p>

<p><strong>HTML</strong> </p>

<pre><code>&lt;div id="upload_excel" class="dropzone form-control"&gt;

    &lt;div class="fallback"&gt;
        &lt;input name="file" type="file" multiple /&gt;
    &lt;/div&gt;

&lt;/div&gt;
</code></pre>

<p><strong>JS</strong></p>

<pre><code>var baseUrl = "{{ url('/') }}";
var token = "{{ Session::getToken() }}";

Dropzone.autoDiscover = false;

var myDropzone = new Dropzone("#upload_excel", {
    paramName: "file",
    acceptedFiles: ".xls,.xlsx",
    maxFiles: 1,
    maxFilesize: 10,
    url: baseUrl + "/upload",
    params: {
        _token: token
    }
});
</code></pre>

<p><strong>Controller</strong></p>

<pre><code>class UploadsController extends Controller
{
    public function upload(Request $request) {
        return $file = $request-&gt;all();
    }
}
</code></pre>
