How do I create a form that two submit buttons, where each one
submits the form input data to a different server?

Consider this situation: I have a form where users can check various
options to subscribe to a service, and each option costs a certain
amount. When the form is submitted, my php script totals up the
options. Fine.

The form has 2 submit buttons: "print invoice" and "pay by credit
card."

The "print invoice" button is for those businesses who can't pay by
credit card but must mail us a check instead; they print an invoice
for their accounts payable department. The php script generates the
invoice based on the form inputs. Easy, no problem.

The problem is "pay by credit card." The total cost from submitted
input fields must be POSTed to a different server: our credit card
processor.

This isn't a problem if the credit card processor accepts the
form input data as a GET string in the URL; all I'd do is
header("Location: $url"); to redirect the user to the credit card
processor page which handles the payment. The problem is I need
to do this by POSTing the form input data, while at the same time
retain the ability to generate invoices from MY server using the
same form.

I can't think of an elegant way to do this except to have two
different payment pages each with their own form. Or maybe force
everybody to generate an invoice as the first step, and after that
point they can choose to pay it by credit card.
