I use the following UDF:
<cfscript>
function fnNumbersOnly(str) {
return reReplace(str,"[^[:digit:]]","","all");
}
</cfscript>

Subject: strip all non-numeric characters from a string
We are having an issue with users entering their phone numbers and credit
card info. How would I strip a string of all non-numeric characters. I'm
sure it involves rereplace() but I'm no good with regular expressions.
Thanks for any help.
Right now for the credit card I have this which just strips out spaces and
dashes: <cfset attributes.billingCardNumber =
replace(attributes.billingCardNumber, " ", "", "all")> <cfset
attributes.billingCardNumber = replace(attributes.billingCardNumber, "-",
"", "all")>
