FrankWatching plugins

2011 – WordPress, Social Media

Several plugins for the new Frankwatching site, such as a plugin to enable voting for a
post/page (like/dislike), a plugin to help cache Twitter feeds so the information is not
pulled from Twitter with each page request and a plugin which counts page views per
author in combination with the Co author plugin. These numbers can also be cached

Jantje Beton Lottery

2011 – WordPress, Gravity Forms, iDeal

This is a plugin which enables selling lottery tickets through a WordPress site, the plugin
requires GravityForms and the Pronamic iDeal plugin for GravityForms. An administrator

buying a ticket and could show an overview of which projects are sponsored by how
many lottery tickets.

FNV Kennisbank

2011 – WordPress, XML, REST, SSO, JSONP, PHP, JavaScript

For LevelLevel I worked on several plugins for the FNV Kennisbank (a digital tax guide).
I created a plugin which limits access to the site and requires authentication through
another site (also part of the the guide, a single sign on solution), if a user logs in there
they are forwarded to the WordPress site and authenticated there. Account details are
shared between the sites using a REST API. Another plugin facilitated the sharing of
data between three different systems using XML, the plugin would export data and
import data from the other system.
Since the tax rules can be changed each year another plugin allowed all the information
on the site to be archived after a year and a copy created as a new tax guide. (These
are actually 3 types of posts: archived, current and future) With the press of a button a
future guide could be created and once updated this guide could be published while the
previous one was archived.
Other contributions included a way to share search results using JSONP across multiple
sites, a personal bookmark plugin and several tweaks to BuddyPress.

Jantje Beton Projects

I created a WordPress theme for the project Pandemic 1.0, which displayed the story as it unfolded through tweets, moral dilemma’s, Facebook comments, StickyBit scans and Gowalla checkins. All of the information for the website was accessible through data feeds for which I created a WordPress plugin to store and use all this information in WordPress. I also created a theme which displayed a countdown to the project.
