Hooks

In WordPress, hooks are a way to customize and modify the behavior of the WordPress core, themes, and plugins without modifying the underlying code. Hooks allow developers to add their own code to specific points in the WordPress execution process.

There are two types of hooks in WordPress: action hooks and filter hooks.

Action hooks allow developers to execute custom code at specific points in the WordPress execution process. For example, a plugin might use an action hook to add a new section to the WordPress admin menu.

Filter hooks allow developers to modify data that is processed by WordPress. For example, a plugin might use a filter hook to modify the content of a post before it is displayed on the website.

Hooks are defined in the WordPress core, themes, and plugins using the add_action and add_filter functions. Developers can use these functions to specify the name of the hook they want to attach their code to, and the name of the function that should be executed when the hook is triggered.

WordPress also provides many built-in hooks that developers can use to customize the behavior of WordPress without modifying the underlying code.
