Extending Form Validation

[eluser]Aken[/eluser]
First, your file and class name should not have a capitalized V. It should be MY_Form_validation.

Second, there is logic in the class that says "If the field is blank, but NOT required, no further tests are necessary." So if you are testing it with a blank value, your rule won't fire. If you add a value, it should work. This is standard functionality of the library.
