How can I add a PHP function call to my form action attribute?

[maxwell_]

I have a page (page_a) with two functions (function a, function b).
I have another 2 pages each with a form (page b, page c).
When the form is submitted on page b I would like to call page_a function a
When the form is submitted on page c I would like to call page_a function b

Is there a way to add the function call to the action attribute

<form action="page_a.php" method="post" id="form1">

Instead of exposing the internal workings of your site to everyone visiting the page, either give the submission buttons different names and base your decision about which function to run on that, or use $_SERVER['HTTP_REFERER'] to find out which page the submission came from.

I suppose you could add some URL query string name=value pair to the form action, then base your PHP form-handler's logic based on that value in $_GET, but I like the idea of using different names for the submit buttons better.
