Here's the typical way this is done: If the name of the file is myfile.php, then in the file do this: <form action="myfile.php" action="post"> This makes the form return to itself when the user hits the "Submit" button. Above the actual HTML part of the form, put a check to determine if the form has been filled in, like this: if (!empty($_POST)) { // Form was filled in do_validation(); if (! $valid) { $_SESSION['myform'] = $_POST; } } else { show_the_file_for_the_first_time(); } In the do_validation() step, you validate the form. If there is a problem and you want to re-show the form, you would typically do this for each field: <input type="text" name="first_field" value="<?php echo $_SESSION['myform']['first_field']; ?>" ?> In other words, you store the form values in the $_SESSION array.
