Rendering Dynamic Gutenberg Blocks in Theme Template Parts

Gutenberg is an ambitious project that aims to completely overhaul the experience of writing content in WordPress.

One of the problems you’ll soon run into when building a block for Gutenberg is that as a block becomes more complex, storing its complete output statically becomes undesirable. If a block contains several fields or its output contains HTML markup, you don’t want to find yourself in a situation where this output needs to be changed at some point in the future and you need to retrospectively apply changes to stored block output in every post.

Gutenberg supports dynamic block rendering so that you can perform more complex output rendering on the fly, without having to store the complete output when the block is saved. This is the same method that shortcodes in WordPress use and allows you to move away from static block output. If you’re building a block for Gutenberg that uses anything more than very simple output, you should consider using dynamic rendering.

WordPress Contributors on a World Map

As a fun data visualisation experiment – and as a way to practice my new found interest in Node.js – I decided to plot on a map of the world all the people who contributed to the recent release of WordPress 3.6. The map can be seen further down, but first a brief description of how I went about it.

I decided to generate a GeoJSON file of the contributor’s locations so it can be displayed wherever and however the open GeoJSON format is supported, not least on GitHub which recently added support for automatic rendering of GeoJSON files.

A History of WordPress Contributors

I thought I’d run some stats on WordPress contributors over the years. The only contributor stats I have are the ones published in each release announcement on wordpress.org, so I’ve put these stats together myself from those lists.

Unfortunately the release announcements have only listed the contributors since version 2.9 (June 2009). If anyone wants to get me the list of contributors for earlier versions I’ll happily update this post. It’d be interesting to see the numbers over the years.

Saving Post Meta Field Revisions in WordPress

If your plugin or theme uses custom post meta fields then you may want to store revisions to these fields when a post revision is saved. It’s easy to do.

For each of our meta fields, we’ll need to do three things:

  1. Store a revision of the meta field when a post is saved
  2. Revert to the correct revision of the meta field when a post is reverted
  3. Optionally, display the meta field on the revisions screen
