image doesnt upload using multer - node.js

Question

Ok so in my app I am trying to allow image uploading using multer. My app is built using node.js and my database is using mongodb. When I create an account and select an image for the avatar image, it creates the account but automatically uses the no-image.png file I have setup in case someone doesn't select an image. Here is the code... Any help will be awesome.
// handle signup logic
router.post("/register", function(req, res) {
upload(req, res, function(err) {
if(err){
req.flash("error", err.message);
return res.redirect("/register");
}
var newUser = new User({
username: req.body.username,
firstName: req.body.firstName,
lastName: req.body.lastName,
email: req.body.email,
bio: req.body.bio
});
if(typeof req.file !== "undefined") {
newUser.avatar = '/uploads/userImg/' + req.file.filename;
} else {
newUser.avatar = '/uploads/userImg/no-image.png';
}
console.log(newUser);
if(req.body.adminCode === process.env.ADMINCODE) {
newUser.isAdmin = true;
}
if(req.body.answer !== process.env.SECRET){
req.flash("error", "answer the question");
return res.redirect("back");
} else {
User.register(newUser, req.body.password, function(err, user){
if(err){
return res.render("register", {error: err.message});
}
passport.authenticate("local")(req, res, function(){
req.flash("success", "Welcome to Let's Camp " + user.username);
res.redirect("/campgrounds");
});
});
}
});
});
var multer = require("multer");
var storage = multer.diskStorage({
destination: function(req, file, callback) {
callback(null, './public/uploads/userImg');
},
filename: function(req, file, callback) {
callback(null, Date.now() + file.originalname);
}
});
var upload = multer({ storage : storage}).single('image');

If I use enctype="multipart/form-data" I get an error for some reason but if I leave it off it completes but the image still doesnt upload. Just reverts to the no-image.png

Answer 1

If You want to post file You've to use entype="multipart/form-data":
<form action="/register" method="post" enctype="multipart/form-data">
If You've other problems so fix that problem.
from documentation :
.single(fieldname)
Accept a single file with the name fieldname. The single file will be stored in req.file.
So create upload method like this and call it in Your router:
var uploadAvatar = multer({ storage : storage}).single('avatar');
or rename Your input file name="image" :
<input id="avatar" class="form-control" type="file" name="image">
