Custom validation rules?

If you don't prefer creating new class, you might create callback function in your controller - simply put xwero's domain_email function in your controller and use it in your rules in this manner:

Code:

$rules['email'] = 'valid_email|callback_domain_email[gmail.com]';

[/quote]Thanks, I think this will work much easier for me.

Also, how do I go about creating a validation rule that allows spaces? I want to allow only alpha numeric, or just numeric, but also contain spaces. For example, a state name may have two words such as New York, but when you use the alpha or alpha_numeric rule, that returns false.
