If you don't want your PHP page to give out errors as shown in the previous exercise, you should consider checking all expected input fields in $_REQUEST with the isset() function as shown in the example script below:
<?php if (isset($_REQUEST['name'])) { $name = $_REQUEST['name']; } else { $name = ""; } if (isset($_REQUEST['comment'])) { $comment = $_REQUEST['comment']; } else { $comment = ""; } print("<html><pre>"); print("You have submitted the following information:\n"); print(" Name = $name\n"); print(" Comments = $comment\n"); print("Thank you!\n"); print("</pre></html>\n"); ?>
