OK so this is the basic function to reset a radio button after a form has been submitted. What I want to ask is why does the function get the value from $_POST? Why not $this->{$field}??

Surely that would keep in with everything with the class. And also make outputting form data simpler.

Since I know many people use the hack of setting values in the validation class, so they don’t have to then have ugly if statements just to either output a form return value or the value from the DB. But using the above method you can’t do this for radio/checkboxs.

The validation library only takes care of the values that exist after a post request.

Maybe instead of the having these methods in the validation library maybe they should be in the form helper.

edit : changed code

That would be better I think, seems odd having them in the validation library.
