Maybe I'm over-simplifying this. But if you do not want them to update
this field via the web, then don't let them have that ability.
So, is this what you're doing?:
<form action="thispage.php" method="post">
Username: <input type="text" value="<? echo $username; ?>"
name="username" size="30" />
...etc...
Address: <? echo $fieldYouDoNotWantToUpdate; ?>
</form>
Do you see what I'm saying? If you're pulling information from a
database, then just display it on screen as text, then they will for
sure not be able to update it. Otherwise, put it in a modifiable
<input/> or <select> field.
Hope that helps.
