Is Valid function

Hi,

Here's what I usually use:

Defining the variables in the config script:
========================================
<cfset application.password_regexp= "^(?=.{8,})(?=.*[A-Z])(?=.*[a-z])(?=.*[0-9]).*$">
<cfset application.password_info= "A strong password is required (include [A-Z], [a-z], [0-9] {6})">

The verification:
========================================
<cfif REFind(application.password_regexp,value) IS 0>
<cfset PAGE_MESSAGE= PAGE_MESSAGE & "- #application.password_info#\n">
</cfif>

cheers,
fober

Right, so to clarify your original post, you want the string to have at
least one each of these three things:
- an uppercase letter
- a lowercase letter
- a digit.

So:
"Aa1" is fine, because it has all three.
"AA1" is not fine because it doesn't haev any lowercase letters.
"Aa1!" is not fine because it has a character other than letters and digit.

Not just "some mix of characters including any of uppercase, lowercase and
digits", which is what your post reads like.

I didn't know the answer to this off the top of my head, but googled
'password regex "upper case" and "lower case" and digits', and found the
answer pretty much straight away.

Google rocks.

Hi,

Can please explain a bit more?

Have you read the docs on regexes, and have you had at least a stab at
doing it yourself? What did you come up with?
