uploading 2 images with req.files[0].filename, req.files[1].filename,

i can edit and update the first record only with req.files[0].filename, req.files[1].filename,

NOTE i can upload and save images then read it from mongodb but when i want to update it, it's only update the first 2 images with this position
req.files[0].filename, and req.files[1].filename

Here is my code:
1. uploading 2 images and everything goes alright

router.post('/upload', upload.any(), function(req, res) {

  if (!req.body && !req.files) {

    req.flash('error', 'error');

    res.redirect('admin/home');

  } else {

    var c;

    Photo.findOne({}, function(err, data) {

      if (data) {

        c = data.unique_id + 1;

      } else {

        c = 1;

      }

      var oto = new Photo({

        unique_id: c,

        smallcaption: req.body.caption,

        smallpath: req.files[0].filename,

        bigyear: req.body.year,

        bigtitle: req.body.title,

        bigcategory: req.body.category,

        bigpath: req.files[1].filename,

      });

      oto.save((err, Person) => {

        if (err) return err;

        console.log(req.files);

        req.flash('success_msg', 'Your Project Has Been Saved !!!');

        res.redirect('admin/home');

      });

    })

      .sort({ _id: -1 })

      .limit(1);

  }

});

****2. editing (Updating) my 2 images but only first record is updated****

    router.post('/edit-project/(:id)', upload.any(), function(req, res, next) {

          var otos = {

            smallcaption: req.sanitize('smallcaption').trim(),

            smallpath: req.files[0].filename,

            bigyear: req.sanitize('bigyear').trim(),

            bigtitle: req.sanitize('bigtitle').trim(),

            bigcategory: req.sanitize('bigcategory').trim(),

            bigpath: req.files[1].filename,

          };

          var o_id = new ObjectId(req.params.id);

          db.collection('photos').update({ _id: o_id }, otos, function(err, result) {

            if (err) {

              req.flash('error_msg', 'Error Occurred When You Updating Your Data !!!');

              res.render('admin/edit-project', {

                smallcaption: req.body.smallcaption,

                smallpath: req.files[0].filename,

                bigyear: req.body.bigyear,

                bigtitle: req.body.bigtitle,

                bigcategory: req.body.bigcategory,

                bigpath: req.files[1].filename,

              });

            } else {

              console.log(req.files);

              req.flash('success_msg', 'Data updated successfully !!!');

              res.redirect('/admin/home');

            }

          });

        });

3. uploading form
