CODE if(isset($_POST['Book'],$_POST['Price'])){ $book = $_POST['Book']; $Price = $_POST['Price']; } The above means the variables are not set if the form page is loaded without a previous form submission: CODE <title>Order Form for <?php echo $_POST['Book']; ?></title> ... <h1> Order form for <?php echo $_POST['Book']; ?> at (AUD) $ <?php echo $_POST['Price']; ?> </h1> (As a sidenote, there's no sanitation of the above POST data. Possibly a malicious user could inject unwanted code in your PHP script that way, like manipulating the price.) |
