What is this?

If you're a plugin developer, you know how difficult it can be to figure out which hooks are available. This WordPress hooks database automatically scans each WP build for apply_filters() and do_action() to figure out exactly which hooks are available in each version and where the hooks occur.

If you don't know what WordPress hooks are for, read the Plugin API .

What is this good for?

• See what new hooks are available with each new version of WordPress
• See which hooks have been deprecated (use the "view all hooks" option)
• Easily learn exactly which WP file(s) use each hook. That way, if the hook is poorly documented, you can just look in the source and figure out what it does.
• For over 380 of the most-used hooks, you can read a brief description of the hook. These are scraped from the official WordPress documentation's action reference and filter reference .

How to help?

Update and improve the official action and filter references. Next time we scrape those, your contributions will show up here.
