I'm into developing a shopping cart using PHP (naturally) and am running 
into a little snag.
I need to be able to perform several tasks within the framework of a 
<form></form> construct:

1)      Call a function from within the module;
2)      Call an external PHP module (no return) with the contents of ALL 
elements within the form;
3)      Call an external (or a function) that will overlay a smaller window 
to display cart contents and
         have the customer click a button to close the window (return?). 
All FORM contents needed;

Here is the pseudo code, subject to MAJOR change (obviously) ...

<?
function function_one()
{
   print ("I'm in function one ...");
}
?>
<html>
<head>
</head>
<body>
<form>
This is program one ...
<?
   print ("<a href=\"bob2.php\"> click here</a>");   <---- This needs to 
transfer to
                                                           another module, 
not returning.
   print ("<input type=???">);                       <---- This needs to 
enter function_one
                                                           and remain 
within the module
   print ("???????????????");                        <---- This needs to 
transfer to another
                                                           module (or call 
another function
                                                           within this 
module) to open another
                                                           window, display 
the contents of a
                                                           shopping cart, 
then have the customer
                                                           click a button 
to close with window.
   ?>
</form>
</body>
</html>

Can anyone return this with some pseudo code?

Bob
