Well, you could make all elements in a div container uneditable via JQuery if you want it fast and dynamic.
<div id="committee">
<?php include 'committee_members_list.php'; ?>
</div>
<script type="text/javascript">
$("#committee").each(function() {
$(this).attr("readonly", "1");
});
</script>
For more security you have to validate everything serversided anyway if it is a form anyway.
But are input elements nesessary anyway if the content is for read only?
