Multiple forms with shared fields

Question

How to make multiple forms with shared fields without using javascript?

<input type=text name=username />
<form action="/users">
    ... some fields ...
</form>
<form action="/admins">
    ... some another fields ...
</form>

Answer 1

It is no necessary to have the input tag inside the form: an input can be associated with its form using its form attribute.

It would be nice if forms could share inputs, but i haven't heard of this. Maybe we should ask W3C to introduce this in HTML6?

UPDATE: One workaround would be to have a single form with multiple "Submit" buttons, using <input type="submit" name="..." value="..." /> or <button type="submit" name="..." value="...">...</button> elements, so that all the fields get submitted when any button is pressed, and the server side can then check which button was pressed.
