express multer Cannot read property 'profileimage' of undefined

Question

I am trying to submit a form which has a file input within it with a name of

profileimage

, i am using express 4, express generator and multer.

In my

app.js

I added multer like so:

var multer = require('multer');

var upload = multer({ dest: './uploads' });

The tutorial i am following actually sets up multer like so (after requiring it) but it gives me an error:

app.use(multer({dest: './uploads'}));

And in my

routes

folder inside the respective file I have the following:

router.post('/register', function(req, res, next) {

// get form values

var name = req.body.name;

var email = req.body.email;

var username = req.body.username;

var password = req.body.password;

var password2 = req.body.password2;



// check for image field

if (req.files.profileimage)

{

    console.log('Uploading file...');

...

However when I submit the form I get the following error:

Cannot read property 'profileimage' of undefined

It seems to not be able to understand

req.files.profileimage

, but I don't know why?

The API for multer changed a bit some time ago, so some tutorials out there still use the old API.

For a single file, you would do something like:

var uploads = multer({dest: './uploads'});

// ...

router.post('/register', uploads.single('profileimg'), function(req, res, next) {

   // ...

   if (req.file) {
     console.log('Profile image uploaded');
   }
});

See the multer documentation for more examples of other scenarios.
