What Is a Custom Field

A custom field is a key+value pair that’s associated with a particular post. Once a key is made, it can be used for other posts, with different values. The key is the name of the custom field, and the value is the information contained by the field. The key+value information is also known as meta data. It is stored in a database table called wp_postmeta.
