link in place of a submit button at the bottom of this. can't get it.
i'm just starting to learn php, so i'm stuck. any help at all would be
amazing.

submitted.

if (empty($_POST['username'])) { // Validate the username.
$u = FALSE;
echo '<p><font color="red" size="+1">You forgot to enter your
username!</font></p>';
} else {
$u = escape_data($_POST['username']);
}
