In addition to the ReReplace() function, as a first line of defense or if
I'm feeling lazy :-). I use javascript to make sure they cant even type the
characters I dont want them to be able to type.
It's called very easily like so:
<input type="text" name="whatever" onKeyPress="return letternumber(event)">
Put this in your head
<SCRIPT TYPE="text/javascript">
<!--

function letternumber(e)
{
var key;
var keychar;
if (window.event)
key = window.event.keyCode;
else if (e)
key = e.which;
else
return true;
keychar = String.fromCharCode(key);
keychar = keychar.toLowerCase();
// control keys
if ((key==null) || (key==0) || (key==8) ||
(key==9) || (key==13) || (key==27) )
return true;
// alphas and numbers
else if ((("abcdefghijklmnopqrstuvwxyz0123456789").indexOf(keychar) > -1))
return true;
else
return false;
}
//-->
</SCRIPT>
