One way I found useful was to use JavaScript on the client-side
to test if they were numbers or not. Then you know only numbers
are being submitted.

: I am trying to do some server side validation for a phone number, but I am
running into an odd problem. I split the phone number entry form into three
textboxes the first one for area code (ie must be 3 numbers) and then the
two parts of the phone number (ie must be 3 numbers and then must be 4
numbers). I check to make sure the length of each textbox is correct and
then I try to check if they are numeric, however it will throw an error.
:
: My code looks something like this:
:
: <cfif not IsNumeric("attributes.custPhone1") or not
IsNumeric("attributes.custPhone2") or not
IsNumeric("attributes.custPhone3")>
: <cfset attributes.error = attributes.error & "Please enter a valid
phone number.<br>">
: </cfif>
:
: The strange part is that when I take out the not IsNumeric() statements
for the first two form variables it works fine. Ideas???
