The Directive and Controller

            function fn_link(scope, element, attrs) {

                    formdata.append(key, value);
                });
            };

            // NOW UPLOAD THE FILES.
            $scope.uploadFiles = function () {

                var request = {
                    method: 'POST',
                    url: '/api/fileupload/',
                    data: formdata,
                    headers: {
                        'Content-Type': undefined
                    }
                };

                // SEND THE FILES.
                $http(request)
                    .success(function (d) {
