HTML Sanitisation is pretty important where user input is concerned, not doing so can easily let your users do some pretty funky things to your site.

The latest versions of the Known engine support a hook to call a sanitisation plugin when outputting bodies of text. The hook is called automatically whenever autop is called, but you can call it yourself if you want to.

Anyway, it would be remiss of me if I didn’t implement something that listened to this hook, so here’s a Known html sanitiser powered by HTML Purifier.

Check out the plugin, install and activate it in the usual way. Enjoy!

A client asked me to poke around on, a social networking and microblogging platform, which also serves as a reference implementation of their API.

Since the best way to understand an API is to start using it, and since I try my best to be a good Open Source citizen, I put together a basic stub of a Known plugin for it.

This plugin provides basic syndication support for status messages and long form posts, and serves as a useful starting point for more exciting integrations.

Anyway, have a play, comments and pull requests to the usual places!
