Disregard my previous posting. I was wrong about the change to the _CF_checkcreditcard function.

I've discovered the problem with the .
In the cfform.js, the last line of the _CF_checkcreditcard function needs to flip the return true/false.

original:
return (checkdigit % 10) == 0 ? true : false;

should be
return (checkdigit % 10) == 0 ? false : true;

After this change, the validation worked perfect.

And oh yeah: since then, I figured out a way around the problem by having the regular expression match a null field as well as what you're searching for if you want it to be not required. This is not intuitive, and I would still argue that the regular_expression validation attribute breaks the "required" attribute, but for example for emails, the following works to validate an email address if one is given, but not to require one:

VALIDATE="regular_expression" PATTERN="(.+@.+\.\w{2,6}$|^$)"

Let's be clear: you're NOT writing a function, you're using a new attribute added to the ColdFusion Tag (Validate="regular-expression"). This new attribute breaks other attributes in unexpected ways (ie: the "required" attribute is no longer respected). This is a bug, and it is not documented on this page except for my comment about it.

I was hoping this new attribute would allow me to stop having to use the special extra validation function I wrote for email, but alas, with this bug making it is not ready for production, the answer is "no".

Well, if you are writing a function to validate the input, check to see if it is blank, and if it is, perform a javascript "alert()". Come on, this isn't that hard.
And it says in the doc right above it behaves this way.

Validating on a "regular_expression" seems to then ignore the absence of a "required" -- ie: if you don't have REQUIRED="Yes" it still tries to validate an empty field. Even using REQUIRED="No" does not keep it from trying to validate an empty field.

I just copied the above script and trie it on my webserver with ColdFusion MX server.
The required fields are not checked.
The TAGs and are not usable at all.

I am using cfinput type="file" for the form side of the cffile action, but I don't see that type as an option on this page.

The check requires 16 digits in the number.

Credit card validation seems to only look for a 20-number credit card, but AMEX cards have less than 20 numbers.

cfinput should have an ending tag and allow for a type=textarea
