What does it mean?
As a web developer, a Filter Hook is a powerful tool that allows me to modify or manipulate data before it is displayed on a website. It is a function that is triggered when a specific event occurs, such as when a user submits a form or when a page is loaded. The Filter Hook allows me to intercept the data that is being processed and apply custom logic to it. This can be useful in a variety of scenarios, such as when I need to modify the content of a blog post or when I want to add custom functionality to a plugin. By using Filter Hooks, I can easily customize the behavior of WordPress and other web applications without having to modify their core code.
