Update Aug 2, 2013: See the quest continues for updated information on how this series is proceeding.
In the scheme of things, hooks and filters are some of the least documented parts of the WordPress code base. The Docs Team recently 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 filters list, I pulled 1003 total filter hooks, divided by three, that comes to about 335 filters. I’m going to attempt to write example filters for three filter hooks a day for a year. And I’ll intermix 30-or-so filters from popular plugins to round out the total.
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 Codex/Code Reference, wherever filters may fall into the new roadmap. You can see the list after the jump.
