October 9, 2018 — Gutenberg is a major change to how you develop software for WordPress. The changes will start with the WordPress editor but the long term plan is for Gutenberg to slowly take over the entire admin interface.

If you already have existing plugin or theme code that you need to maintain and make ready for the upcoming Gutenberg update, you will probably face some architectural design challenges. This session will help prepare you to make those changes in a clean transition.

October 5, 2018 — We will look at the basic mechanisms that make Composer as flexible as it is. Then, we’ll go through some of the more useful and/or exotic examples of how to use Composer for solving problems that it wasn’t really meant to solve.

August 7, 2018 — You know a lot of pattern buzzwords and OOP syntax, but fail to get actual benefits out of their practical use? You’ve read about principles and best practices but cannot apply them to your daily problems? We’ll work on a simple WordPress plugin to discuss fundamental principles like dependency injection and discover useful design patterns that solve real pain points in your development work. We’ll combine these techniques to give you strategies to better deal with ever-changing requirements.

This workshop assumes solid knowledge of PHP and basic knowledge about classes and objects, how the PHP OOP syntax works and what the notions of polymorphism, encapsulation and inheritance mean.

December 25, 2017 — As the plugins you develop grow bigger, you need to spend more effort on getting the structure just right, to keep the plugin maintainable and easily extensible.

This session will briefly go over several key concepts of dealing with growing plugins, like using Composer to split your plugins into multiple reusable libraries or using a dependency injector to make the code independent of any specific implementations.

The session assumes knowledge of basic OOP principles and is an unofficial follow-up to the session “OOP Plugin Development Basics” held at WordCamp Nijmegen 2017.

December 8, 2017 — This session tries to give a brief glimpse into the timeframes and the usefulness of Computer Science as a discipline and wants to make the point for looking at known solutions first before reinventing the next few wheels.

December 1, 2017 — Das Pluginkollektiv hat einige beliebte Plugins von Sergej Müller übernommen und betreut und entwickelt die Plugins weiter. In dem Video erzählen euch Entwickler des Pluginkollektivs was es damit auf sich hat und zeigt euch wie ihr mitmachen könnt.

October 14, 2017 — Building WordPress plugins in an object-oriented way presents some particular challenges, due to the fact that the WordPress APIs you’re coding against are mostly procedural in nature.

In this session, we’ll go over a real-world plugin to see how the code should be structured, and how best to hook into the WordPress lifecycle when you want to take full advantage of the benefits of OOP PHP.

June 22, 2017 — Alain is a freelance software engineer and WordPress consultant living in Germany.

This session presents a detailed overview of the exact execution flow that launches your WordPress site on each page request, giving you detailed insights into:

the order in which files are loaded
how & why the different global constants are set up
what functionality is “pluggable” and can be replaced by custom implementations
how the database is connected
how caching is set up
how localization is set up and loaded
how a multisite (network) is identified and loaded
how the Plugin API is initialized

June 6, 2017 — Alain is a freelance software engineer and WordPress consultant.

In his talk he presents a case study of wrapping a legacy WordPress site into a scalable architecture, using a combination of existing and custom packages, that provides the following benefits:
– services architecture that lets plugins define their dependencies, with automatically resolved loading order
– auto-wiring dependency injection that allows coding against interfaces instead of implementations
– configuration management that can account for differences in environments
– centralized logging throughout the entire site that can be sent to logging servers
– bus system that handles events and commands without blocking the frontend
– all of this without any noticeable impact on content editors

May 22, 2017 — If you manage more than one WordPress website, you might have experienced situations where you needed to do the exact same operation on multiple websites. If you were clicking through the sites one-by-one and thinking that there should be a better way to manage what you are trying to do, I’ve got good news: there actually is!

WP-CLI lets you control your WordPress sites through the command line, allowing you to do any operation across an arbitrary number of sites. This can save you minutes, hours, days or even weeks of work.

I’ll start with a small introduction to the command line itself, and then continue with very easy and common scenarios where WP-CLI can save you large amounts of time with little to no effort.
