Recently, I was having a conversation with a friend about some of the various ways to serialize the values that are present within a collection of meta boxes that are defined for any type of post – be it a post, page, or a custom post type – within WordPress.
For example, imagine that you have a custom post type that has, say, four different meta boxes that are available below the main content area.
These meta boxes can be laid out in one of two ways:
- The meta boxes can be listed individually with each meta box having its own set of values. Think of WordPress’ Excerpt field, Discussion field, and and Sharing Field.
- The meta boxes can all be contained within a single container accessible by individual tabs.
The question is does the way that the meta boxes are displayed influence how the values are serialized in the database?
