I've had good luck using the Formulator product, it has an email field validation mechanism. Works very nicely. -Jon Cyr Small Business Services wrote:

The situation is that i want user to register. and i want to check the user-provid email address format.
<dtml if "email=='' or.....">
how can I check the email format?
Create an external method with the following code:
import re
def isEmail(value):
p = re.compile(r"(([\'a-zA-Z0-9\_-])*\.)*([\'a-zA-Z0-9\_-])+@([a-zA-Z0-9\_-])+(\ .([a-zA-Z0-9])+)+") if p.match(value) : return 'Valid' else: return 'Invalid'
Then you can use dtml to check your email addresses:
<dtml-if "isEmail(somevar) == 'Valid' ">
where 'somevar' is the form field that captured the email address entered by the user.
