                        @foreach ($errors->all() as $error)
                          <li>{{ $error }}</li>
                        @endforeach
                    </ul>
                </div>
              @endif
                <div class="custom-file">
                    <input type="file" name="file" class="custom-file-input" id="chooseFile">

                </div>
                <button type="submit" name="submit" class="btn btn-primary btn-block mt-4">
                    Upload Files
                </button>
            </form>
