I am rolling my own MYSQL shopping cart. One of my requirement is the catalog will be static html files.  I have embedded the following into my web page. <form action="http://www.[my page]addcart.php" method="post"  NAME="order" id="order">       Quantity: <input type=text size=2 maxlength=3 name=QUANTITY >   <?php   header("Location: http://www.[mypage]setInputbutton.php?item=44005"); ?>       <input type=hidden name="ID_NUM" value="44005">           </form > The way it works is in the form I call SetInputbutton.php with the catalog number. The script queries database to get the quantity  in stock. If good it echos the place in cart button, if below a set point it places the number in stock and a place in cart button and if zero, echo only out of stock preventign purchase. The script works but When I view HTML source; it shows the entire PHP script. The question is how to hide the PHP script for prying eyes.
