I am still searching for the “right” coding standards in Advanced Ads that is consistant as well as easy to implement and understand. However, a few things are settled. You can remind me in case I “forget” something I said here in my code or use it inconsistantly.
start with prefix advads_
start with prefix Advads_
lower case letters with readable words and underscores between them, e.g. class_ad_object.php
e.g. classes and ids
lower case and hyphens, e.g. advads-metabox
lower case with hyphens and prefix advanced-ads-
