I am working with Multer and Multer S3 to allow users to upload images on a Node project. I am wanting the user to be able to upload 3 images regardless of their size but no more. If a user tries to select say 6 images I get this error page:
Error: Unexpected field
at makeError
How would I change my code below to not allow a user to select/upload more than 3 images and/or handle the error in a better way.
Partial Code:
router.post("/", upload.array('image', 3), function(req, res, next){
var filepath = undefined;
var filepath2 = undefined;
var filepath3 = undefined;
if(req.files[0]) {
filepath = req.files[0].key;
}
if(req.files[1]) {
filepath2 = req.files[1].key;
}
if(req.files[2]) {
filepath3 = req.files[2].key;
}.....
Update:
I added this and now I land on a "too many files" error page if the user tries to upload more than 3. Now I just have to figure out how to redirect if too many files.
var upload = multer({
limits : { files: 3 },
