Question

Is to possible to submit two forms simultaneously with either javascript or a submit button?

Form structure is ok something like this:

Answer 1

No, this is not possible. You can create a third hidden form, that will serialize fields from both of them.

If you can use jQuery:

var str1 = $("form1").serialize();
var str2 = $("form2").serialize();
$.post(url, str1 + "&" + str2);

You need to make sure that str1 and str2 aren't empty and of course avoid name conflicts between the two forms.
