File upload using .fetch() in ReactJS

Question

I am trying to upload file using .fetch() in ReactJS as Front End and Laravel as Back End. My ReactJS code is like below

update= (event) => {
let uploadImage =  event.target.file;
let form = new FormData()
form.append('uploadImage',uploadImage)

fetch('http://127.0.0.1:8000/api/addresses/upload', {
  headers: {
    'Authorization': 'Bearer ' + Auth.getToken(),
    'Content-Type': 'multipart/form-data',
  },
  method: "POST",
  body: form,
})
.then(response => response.json())
.catch(error => console.error('Error:', error))
.then(response => console.log('Success:', response));
}

My Laravel code is like below

public function fileUpload(StoreImageRequest $request)
    {
        $image           = $request->uploadImage;
        $imagename       = time() . $image->getClientOriginalName();
        $destinationPath = public_path('/images');
        $uploadValue     = $image->move($destinationPath, $imagename);
        if ($uploadValue) {
            return response()->json($imagename);
        }
    }

I am getting error like below

and

Where is the issue ?

Answer 1

It's because you upload the image with form field name avatar, but in your Laravel method you access it with uploadImage.

So you can try change it to the following:

$request->avatar

Please checkout the Laravel Files documentation and make sure you follow their best practices.
