In the scheme of things, hooks and filters are some of the least documented parts of the WordPress code base. A few years ago, the WordPress docs team developed a roadmap for the future of WordPress documentation and as I was part of the team that developed it, I’m none too aware of where the dry patches are. So I decided to do this thing.

From Adam Brown’s hooks list, I pulled 2500+ filter and action hooks. That’s a lot of examples to write but maybe I can help some people discover new and interesting ways to extend WordPress.

These examples may not all be awesome, but that’s the beauty of crowd-sourced code reviews, we’ll get it as right as we can. And of course the bonus of all this, is that hopefully we can put some/many/all of these examples to use in the Code Reference, wherever filters may fall into the new roadmap.
