Part 4 of my Reusable Custom Meta Boxes tutorial series on WPTuts+ is set to publish next week which will go over how to use the various types of data stored with the fields we create through each part of the tutorial. Since I first started the series, I’ve made some major improvements that make their resuability even better. Since this seems to be an ever growing project, I’ve set it up on GitHub. This way, you can watch the project for more improvments and for new fields that I add. It’s open source, so you can even contribute to it!
