Hooks are referenced in the database and are represented in the core via the Hook class defined in the /classes/Hook.php file.

The fields describing a hook in the prefix_hook table are as follows:

• The name column is used in the code as the string identifying the hook; it must be unique.
• The title column is the short text describing the hook.
• The description column is the longer text to define what the hook does.
• The position column is a Boolean always equal to true. It is not used anymore but stays in the code.
• The active column is a Boolean equal to false if the hook is not active, and equal to true if the hook is active.
