Extending Functionality Through Custom Fields
Tips & Tricks
- If I need to customize the feed for a separate app to consume (like a flash file), I’ll create a separate feed file to
customize, leaving the original alone
- I typically will create a separate folder for files that control core theme functionality and name it functions
- Also, I’ll usually do the same for items I need to display on the or within the theme template or feed, which will be called
includes
- All code from the Guest Author example can be downloaded at GitHub - https://github.com/schoffelman/WordCamp-
