Using JavaScript to submit a form with multiple submit buttons

Question

I am a newbie to JavaScript, so hopefully someone can answer
this for me.
On my user registration form, I have two buttons that submit
the form, 'check_availability' (to check if the username is
available) and 'register'. In my PHP script, I check which button
was pushed by checking which POST value is set,
$_POST['check_availability'] or $_POST['register'].
If I set the 'register' button to a JavaScript function that
validates the form and then submits it, how do I get my PHP script
to think 'register' was pushed?

Answer 1

Sorry I used my old captcha script there.
[php]
<?
session_start();
if(isset($_POST['button_name'])){
//DO SOMETHING HERE
} else {
//Add the page data
?>
[/php]
