How to get nested form data in express.js?

If you are using express.bodyParser you can use array notation to pass nested data.

Add express.bodyParser middleware before your controllers.

app.use(express.bodyParser());

Now you can use this notation in your html code:

<input type="text" name="person[first]" /><input type="text" name="person[last]" />

<input type="text" name="person[name][first]" /><input type="text" name="person[name][last]" />

Update for Express 4

The key here is setting extended: true

app.use(bodyParser.urlencoded({  extended: true}));
