I believe he wants to redisplay the values that the user entered if the form fails validation and needs to be edited and resubmitted.

When you validate each feild set each one as a session. Something like this:

$_SESSION['name'] = $_POST['name'];

Therefore when the page validates you could do the following to each input.

<input type='text' name='name' value="
<?php 
if (isset ($_POST['name'] && !empty ($_POST['name'])) {
echo $_POST['name'];
}
 ?>
">

The code above wont work however it gives you an outline of how what you want can be done.
If you need help coding the system please say.

Hope this helps
