What is a Meta Box in WordPress? It’s an interface to interact with metadata. Bam, that’s it.
In the back-end, WordPress has built-in meta boxes for categories, publishing, tags, and the featured image. You can build a custom one which has the HTML form fields to provide an interface to work with the custom fields (metadata).
For example, this is the meta box I built for the episode configuration:
What do you notice? It has a checkbox, select dropdown, and text input fields. Bingo, it’s a form with form fields. Remember what I taught you previously. Custom fields are these fields, as they are user interface-centric, whereas metadata is code and data centric. Same pieces of interface.
Whoever says that coding is hard, just smack them.
