当我使用标准文本时，ajax没有问题，但我想上传文件，我看不到文件数据。
控制器或路由文件没有问题。此外，我的添加表单和更新表单相同。
我在网上搜索了一下，我找到了上面的代码，但我不知道如何使用它？
数据：新FormData($("#slogan"([0](，
谨致问候。
我的html代码低于
<form method="post" id="slogan" class="form-horizontal" data-toggle="validator" enctype="multipart/form-data">
{{ csrf_field() }} {{ method_field('POST') }}
<input type="hidden" name="id" id="id">
<div class="modal-body">
<div class="form-group">
<label for="message-text" class="control-label">Upload Image</label>
<input type="file" id="logo" name="logo" class="form-control">
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Exit</button>
<button id="tamamla" type="submit" class="btn btn-primary btn-save">Save</button>
</div>
</form>
我的Javascript代码低于
<script type="text/javascript">
var table = $('#slogans-table').DataTable({
processing: true,
serverSide: true,
ajax: "{{ url('api/slogan') }}",
columns: [
{data: 'id', name: 'id'},
{data: 'title', name: 'title'},
{data: 'description', name: 'description'},
{data: 'logo', name: 'logo'},
{data: 'hotel.name', name: 'hotel.name'},
{data: 'lang.code', name: 'lang.code'},
{data: 'action', name: 'action', orderable: false, searchable: false}
]
});
function addForm() {
data:new FormData($("#slogan")[0]),
save_method = "add";
$('input[name=_method]').val('POST');
$('#modal-form').modal('show');
$('#modal-form form')[0].reset();
$('.modal-title').text('Slogan Ekle');
}
function editForm(id) {
save_method = 'edit';
$('input[name=_method]').val('PATCH');
$('#modal-form form')[0].reset();
$.ajax({
url: "{{ url('slogan') }}" + '/' + id + "/edit",
type: "GET",
dataType: "JSON",
success: function(data) {
$('#modal-form').modal('show');
$('.modal-title').text('Slogan Düzenle');
$('#id').val(data.id);
$('#name').val(data.name);
$('#hotel_id').val(data.hotel_id);
$('#lang_id').val(data.lang_id);
},
error : function() {
alert("Data Bulunamadı");
}
});
}

namespace AppHttpControllers;
use IlluminateHttpRequest;
use Validator;
use AppAjaxImage;
class AjaxImageUploadController extends Controller
{
public function ajaxImageUpload()

public function ajaxImageUploadPost(Request $request)
{
$validator = Validator::make($request->all(), [

if ($validator->passes()) {

$input['image'] = time().'.'.$request->image->getClientOriginalExtension();
$request->image->move(public_path('images'), $input['image']);
AjaxImage::create($input);
return response()->json(['success'=>'done']);
}
return response()->json(['error'=>$validator->errors()->all()]);
