Custom fields are a type of metadata you can add to your post types in WordPress. They work as key-value pairs where you define a field name and assign it a value, making it easy to store structured information like prices, dates, locations, or any other data you need. They’re especially useful for building custom post templates or when you need consistent, structured data across multiple posts.
This document will show you how to add custom fields with toolset to a regular post, but the method is the same for a custom post type as well.
