I'm creating a login form and want to make a database call and wanted to supply both username and the password and check those against whats in the database. Is there a way to access values of another element while in a callback method of a single element?

If you are using "callback" Rule, the callback will get the element's value, not the element itself. Thus, no.

Or should I try and subclass the quickform rule like you said?

Of course. Also please note that the Rule you add to a Container will currently need to set an error message on Container itself. In your case you'll probably want to do that on this fieldset:

Some code:

         $fieldset = $form->addElement( 'fieldset' )->setLabel( 'User Login' );

If you only set the errors on the contained elements, the form will probably be considered valid. Maybe we'll fix that behaviour, though.

In the old QuickForm there were form rules. Is there a way to achieve the same thing in QuickForm2? I want to be able to compare two values from different form elements.

If you just wish to compare two form elements then you should probably use the built-in 'compare' Rule. There is an example for that in builtin-rules.php If you want to create something similar to old "form rule", you should subclass HTML_QuickForm2_Rule and implement validateOwner() and setOwnerError() methods in the child rule. There is no example for this currently, but it should be straightforward.
