Uploading multiple files with multer, but from different fields Node JS

i was in a situation where i were to upload audio file along with a graphic for that particular song so i was to upload to different files an image and audio file so i used a way to do that using multer plugin available on link

var multer = require('multer')
var storage = multer.diskStorage({


destination: function(req, file, callback) {
    callback(null, './public/audio');
  },
  filename: function(req, file, callback) {
    console.log(file);
    if(file.originalname.length>6)
      callback(null, file.fieldname + '-' + Date.now() + file.originalname.substr(file.originalname.length-6,file.originalname.length));
    else
      callback(null, file.fieldname + '-' + Date.now() + file.originalname);

  }
});

const upload = multer({ storage: storage });


router.post('/save/audio',upload.fields([{
  name: 'audio', maxCount: 1
}, {
  name: 'graphic', maxCount: 1
}]) ,(req, res) => {

  const audioFile = req.files.audio[0];
  const audioGraphic = req.files.graphic[0];
  const fileName = req.body.title;


  saveAudio(fileName,audioFile.filename,audioGraphic.filename,req.body.artist,function (error,success) {
    req.flash('success','File Uploaded Successfully')

    res.redirect('/')
  });

})
