WordPress actions vs filters

Both actions and filters use the WordPress hooks system, but they solve different problems.

Action

Run custom functionality

Use an action to send an email, register a post type, enqueue an asset or perform another task at a particular point.

add_action( 'init', 'my_callback' );
Filter

Change an existing value

Use a filter to change content, titles, URLs, settings or other data. The callback must return the filtered value.

add_filter( 'the_content', 'my_callback' );
FAQ

Frequently asked questions

What is a WordPress hook?

A hook is an extension point that lets you run custom code or modify a value without changing WordPress core files.

What is the difference between an action and a filter?

An action runs custom code at a specific event. A filter receives a value, changes it and must return it.

Where should I add the generated code?

Use a custom plugin or the functions.php file of a child theme. A custom plugin is preferable when the feature should remain active after a theme change.

What does hook priority mean?

Lower priority numbers normally run earlier. The default is 10. Callbacks using the same priority run in the order they were registered.

Is the information I enter stored?

No. Code is generated locally in your browser and is not sent to the website server.
