A hook in WordPress is a powerful feature that allows developers to tap into and modify the platform’s functionality without changing the core files.
Think of it as a way to “hook into” WordPress, enabling the customization of how it looks and operates.
There are two main types of hooks:
- Actions: These hooks let you insert or change code at specific points during WordPress’s execution. For example, you can use an action hook to add a custom script or stylesheet to your theme.
- Filters: Filters allow you to modify data before it’s sent to the database or displayed to the user. If you want to alter how post titles appear or adjust the content before it’s shown, filters are your go-to.
In essence, hooks are the backbone of WordPress plugin and theme development, making it possible to extend and modify the platform without altering core files, ensuring seamless updates and compatibility.
