If you don't want to use an array, then you can't place multiple values
in the same field name.

It works or radio buttons because the group together only sends one
value. But hidden fields send one value for each field in the form.
And if you don't use an array, PHP will just overlay each previous value
with the next one of the same name. The result is you get only the last
field.
