Split html forms?

Question

I am wondering if it is possible to split html forms?

Basically I have a normal form

<form action="/post.php" method="post" id="postform">
    <label for="name">Name: </label>
    <input id="name" name="name" value=""/>
</form>

Then I have a ajax image upload, which includes it's own form due to how it works.

Then after that I want to have the submit button for the first form.

I know I can have a javascript submit button, but that shut's out anyone without Javascript. So I am wondering if it is possible to split a form into multiple groups?

e.g. I know this won't work, but it demonstrates what I want to do..

<form action="/post.php" method="post" id="postform">
    <label for="name">Name: </label>
    <input id="name" name="name" value=""/>
</form>

<!-- form for ajax image upload here -->

<!-- continuation of first form -->
<form action="/post.php" method="post" id="postform"> 
    <!-- this button should submit the top form -->
    <input type="submit" value="Submit"/>
</form>

Answer 1

In HTML5 its possible as pointed out at https://stackoverflow.com/a/8380229/556085:

Sample form:

<form id="formID" action="action" method="post">
    Text: <input type="text" value="some_id" name="some_name" />
</form>

And you place the submit referencing the form to submit via its ID where you want

<input type="submit" name="save" value="Save" form="formID" />

You may have different forms which are separated via different form tags, with different ids, then you can fire the form submit event with javascript.

Without javascript on the client, I have no idea how to do it ...
