PHP and Forms

Could someone point out where the action item is in the form below?

<form   name="express" method="post" onsubmit="return check(this);" enctype="multipart/form-data">
	<input name="mode" value="fast" type="hidden" />
	<input name="barno2" value="" type="hidden" />
	<input name="pt" value="{PT}" type="hidden" />
	<input type="image" src="{TPLVAR_WEB_PREFIX}images/paypalexpress.png" alt="Express Checkout with PayPal" name="Paynow2" border="0" id="Paynow2"  />

there is none. that means that the form will post to the same page.

Ok.  Could someone briefly outline the PHP code that will sense, then,  that this page is being called by a form submission, rather than for the first time?

at the top of the page put..

<? if (isset($_POST)) {
          //Actions to perform if page was submitted.

If the $_POST variable exists then the page was called via a form submission.

You can see what the form submits with something like this..

echo "<pre>";
echo "</pre>";

Probably, the action is set dinamically within the javascript check() function. Try to see there and you'll finad something like this

function check(formName){
  document.formName.action = 'path_to_the_page_to_post_to';

Thanks to everyone for submitting.  The first two answers helped me the most. I already knew how to see what gets submitted, but thanks anyway.  And there was nothing in the check function that set the action. But thanks anyway.

Thank you for points, but I don't deserve them. You have been very nice, but you have to award points only to that answer that really help you to solve your problem and not to all who simply tried to help you. I think you should request attention to a moderator and inform you that you wish change your point's assignement.

Yes, I know, but this is the first time I've posted to the PHP group and just wanted to show my gratitude to everyone for responding.  I've posted about 500 questions to other areas of ExpertsExchange that I usually work in and I'm a lot tougher over there,  where I know the people better.  

I'll be tougher next time.  Plus I only  gave you 10% of the points.  Hopefully the other people won't mind too much.
