Re: Re: Am I passing and testing user data correctly?

Thanks chromatic--invaluable example. I tried it and worked like a charm. And I get what you've done, with the exception of the $class variable. Why is it there, where does it get it's value, and what does it return? Also, it seems like the $email in the error string really will never have a value...right?

Good catch on the `$email` variable in the example. It's pretty useless in the error message. :) As for `$class`, the `Validate->email()` call is actually a class method call. You can read it as "call the `email` method of the `Validate` class". Due to the way Perl's OO works, the invocant (the noun: a class or object) you're asking to perform the verb (the method) is passed as the first argument to the method. In an object method call, you'd get the object as the first p arameter. In a class method call, you get the class name. perloot and perlboot have more details.	[reply] [d/l] [select]
