Multipart/form-data with arrays

Question

I have a simple form:

Answer 1

It's probably related to the use of body-parser (especially the urlencoded method) which, by default, works on requests with the media-type application/x-www-form-urlencoded only.

Your main application module probably has some lines like these:

const bodyParser = require('body-parser');
app.use(bodyParser.urlencoded());

I suppose, you could just add the following to have requests of type multipart/form-data parsed as well:

app.use(bodyParser.urlencoded({
  type: 'multipart/form-data'
}));
