WordPress plugin: Wikipedia extract tooltip

Posted by

I’ve never written a WordPress plugin before and was surprised how simple it was. I have knocked up a plugin based on Altreus’s Protip to allow an abstract from Wikipedia to be pulled into a WordPress post using a simple shortcode. Version 1.0 is pretty rough and ready and doesn’t support any amount of customization.
