Hi the7erm

We rejected a similar feature, although we had all ready to commit, because of a cite on a spec on webforms.

Check #2726. I'll close this soon, reply if you have something to add.

I'm not sure if this works with server-side languages other than php, but if you pass key/value pairs where the key has a [something] appended to its name, php will convert it into an array where "something" becomes an index.

So, if you want to pass a multi-dimensional array when posting, you could do something like this:

Let's say you want to pass something like this:

var options = {
 "a":"1",
 "b":{"I":"1", "II":"2"},
}

So that you receive this on server-side (in php in my case):

array(
 "a"=>"1",
 "b"=>array(
  "I"=>"1",
  "II"=>"2"
 )
)

You could pass this in your post:

var options = {
 "a":"1",
 "b[I]":"1",
 "b[II]":"2"
}

It may need a bit of manual parsing in javascript if you had a pre-constructed object you want to pass, but that's easy enough to do using the "for (key in object) {}" method...

i.e.

var options = {
 "a":"1",
 "b":{"I":"1", "II":"2"},
}

var b = options.b;
delete(options.b);
for (i in b) {
 options["b[" + i + "]"] = b[i];
}
