I use a "hidden" variable that only gets set at submit time
<html><body>
<?php
if (isset($_POST['flag'])) {
echo $_POST['in_name'] ."<br>";
echo '<form method=post><br><center>";
echo '<input TYPE=submit value=Back></center>';
echo '</form>';
// do a bunch of other stuff
}else {
?>
<form method="post">
Enter a NAME:
<input type="text" name="in_name" size="90" />
<input type=hidden name=flag value=1>
<input TYPE=submit value=Submit>
<input TYPE=reset value=Reset>
</form>
<?php
}
?>
</body></html>
