The Week in WordPress, 3rd Week of September, 2012
“Treasure Hunting In WordPress Core.” Learning about core code as a way to find existing solutions to coding problems we might encounter.
Brian Krogsgard’s “Mac and Web based tools for WordPress Theme Development” is a nice peek to his development process.
“Filtering the Options API in WordPress.” Could be useful.
Bonus: if you’re in the mood for some drama, head over to this ThemeForest forum thread, where Justin Tadlock, Carl Hancock and Pippins Williamson (among others) talk about the lack of WordPress best practice usages among some of the sellers there.
