How to upload image using ajax in laravel - image

Question

I have a trouble when to upload img using ajax in laravel. I have an error in getClientOriginalExtension() I think that trouble in enctype in ajax because the controller can not read the upload file.
this is my view :
<form name="data-form" id="data-form" enctype="multipart/form-data">
{{ csrf_field() }}
<input type="file" name="img_thumbnail" class="form-control">
</form>
<script type="text/javascript">
$(function () {
$.ajaxSetup({
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')}
});
$('body').on('click', '#saveBtn', function(){
var url;
var registerForm = $("#data-form");
var formData = registerForm.serialize();
$(this).html('saving...');
$('#saveBtn').attr('disabled',true);
$.ajax({
enctype: 'multipart/form-data',
url: '{{ route('blog.store') }}',
type:'POST',
data:formData,
success:function(data) {
console.log(data);
if(data.errors) {
}
if(data.success) {
}
$('#saveBtn').html('Save Data');
$('#saveBtn').attr('disabled',false);
},
error: function (data) {
console.log('Error:', data);
$('#saveBtn').html('Save Data');
}
});
});
});
</script>
and this is my controller
$name_file = time().'.'.$request->img_thumbnail->getClientOriginalExtension();
$request->img_thumbnail->move(public_path('images'), $nama_file);

upload.js
$(function () {
$('#submitBtn').on('click', (e) => {
e.preventDefault();
var formData = new FormData();
let name = $("input[name=name]").val();
let _token = $('meta[name="csrf-token"]').attr('content');
var photo = $('#photo').prop('files')[0];
formData.append('photo', photo);
formData.append('name', name);
$.ajax({
url: 'api/store',
type: 'POST',
contentType: 'multipart/form-data',
cache: false,
contentType: false,
processData: false,
data: formData,
success: (response) => {
// success
console.log(response);
},
error: (response) => {
console.log(response);
}
});
});
});
Controller
class MyController extends Controller
{
use StoreImageTrait;
public function store(Request $request)
{
$data = $request->all();
$data['photo'] = $this->verifyAndStoreImage($request, 'photo', 'students');
Student::create($data);
return response($data, 200);
}
}
StoreImageTrait
<?php
namespace App\Traits;
use Illuminate\Http\Request;
trait StoreImageTrait
{
public function verifyAndStoreImage(Request $request, $filename = 'image', $directory = 'unknown')
{
if ($request->hasFile($filename)) {
if (!$request->file($filename)->isValid()) {
flash('Invalid image')->error()->important();
return redirect()->back()->withInput();
}
return $request->file($filename)->store('image/' . $directory, 'public');
}
return null;
}
}
