What are WordPress hooks and how do they work?

WordPress hooks are functions that allow you to add custom code or modify existing functionality without altering core files. They come in two types: actions and filters.

Can you explain the difference between actions and filters?

Sure! Actions allow you to add or change functionality at specific points in the WordPress execution process, while filters let you modify data before it is sent to the database or the browser.

How do I create a custom hook?

To create a custom hook, you can use the do_action() function for actions or apply_filters() for filters in your theme or plugin code.

Can you give me an example of using a filter?

Absolutely! For example, you can use the the_content filter to modify post content before it is displayed. You would add a function to your theme's functions.php file that hooks into the_content.
