Why wouldn't someone use CFFORM for the client side convenience (not validation, because it is not validation)? If it meets your needs, it is often the fastest way.
Purists like that are part of the reason why I have problems with the development community at large. Why make anything any more complex than absolutely necessary? We're in the business of solving functional and non-functional requirements, and there are no style points awarded for being a cool-guy programmer. ________________________________ From: Charlie Arehart <[email protected]> To: [email protected] Sent: Wed, March 10, 2010 12:38:10 PM Subject: RE: [ACFUG Discuss] validating credit card numbers with CF And while the back-end validation is of course vital, if you want to do it on the front-end as well (in Javascript), note that it’s a built-in feature of CFINPUT, validate=”creditcard”. Yes, yes, I know that purists would never use CFFORM, and I know that you can’t rely on client-side validation for security because it can be circumvented and won’t work if JS is disabled on the browser, yadda, yadda. That’s why I note that this would be subsidiary to server-side validation. Still, it’s a lot more user-friendly to catch it on the front-end first, if you can. All that said, I suppose some will still have more to say. Shields up.
