How to upload multiple files in laravel 11

The approach is to send an array from FE

  const formData = new FormData();
  formData.append('files[]', file, fileName);
  const response = await axios.post('/upload', formData, {
      headers: {
          'Content-Type': 'multipart/form-data'
      }
  });

Above the exact code will depend on what framework is being used. The key part is 'files[]' . Laravel/Php will now treat it as an array.

Backend, in laravel controller

class UploadController extends Controller
{
    public function store(Request $request)
    {
        $files = $request->file('files');
        foreach ($files as $file) {      
            $fileName = $file->getClientOriginalName();
            $fileExtension = $file->getClientOriginalExtension();
        }
    }
}

$files = $request->file('files'); is key.
Can also try $request->files and $request->all() for debugging.

Above lack validation

1. we should validate the files request input
2. validate the filename and extension.

The exact validation rules will depend on your application
