Prevent Manual Admin Notices From Being Moved to the Top

WordPress normally moves all elements with a notice style to the top of the page, but that can be prevented with the wp-header-end class.

Gutenberg and WordCamp.org’s Shortcodes

Corey McKrill presented a case study at WordCamp Portland about the process we went through to build Gutenberg blocks for WordCamp.org.

Setting up WordPress Multisite with SSL on DreamHost

Setting up a Multisite instance on DreamHost isn't as easy as it should be if you want to also have SSL certificates, but it's possible with the right settings.

Guest on Hallway Chats

Tara Claeys and Liam Dempsey have a really interesting podcast where they talk to people in the WordPress community about what it means to be successful.

Moving a Theme Between Theme Roots

WordPress allows you to have multiple theme directories, but moving themes from one to another may result in a fatal error. It's possible to fix that by updating a few options and clearing a transient.

Inspiration

"Even though we might have some very, very strong disagreements as we develop this thing called WordPress, at the end of the day, I think we all agree that when it impacts people's lives positively like that, it's really really special."

Exposing Custom Post Type Meta for Only a Single API Endpoint

I ran into an undocumented and unexpected problem when registering custom post type meta fields for the REST API.

register_meta() exposes meta fields in all REST API endpoints, which can lead to privacy leaks. To avoid that, it can be called conditionally.

`WP_Widget::form()` returns a value

Ever wonder why your IDE complains that your widget's form() method isn't returning a value?

Accessing Post Meta and More Via $post->meta_key

It turns out there's a much better way to fetch post meta than get_post_meta( $post->ID, 'foo', true ): $post->foo.

Using git-svn to Manage Plugins in the WordPress.org Repository

Unfortunately, the WordPress.org plugin repository doesn’t provide a way to maintain your plugin with Git. In the past, I’ve either just used Subversion, or hosted an extra copy on GitHub, and setup Git and SVN side-by-side in the same directory. Awhile ago, I briefly considered using git-svn, because it would allow me to avoid using Subversion entirely, […]

Finding all Sites That have a Plugin Active

I wanted to find out which sites in a Multisite network had a certain plugin active, but couldn't find an existing solution I was happy with. So, I wrote a WP-CLI command to do the job.

Rename WordPress’ Database Prefix with WP-CLI

I wanted to update the database prefix one this site, but most of the tutorials out there have you do it manually. There are some plugins available, but I didn’t trust most of them, and the ones that I did were kind of bloated with other features, and I didn’t want to mess with the […]

WordCamp Seattle 2016 Call for Speakers

We’ve opened the call for speakers for this year’s WordCamp Seattle. Give it a shot if you have any ideas, best practices, use cases, or stories you want to share with the community. I think people are often hesitant to put themselves out there, and that’s definitely understandable, but the WordPress community is really welcoming, and I think […]

Regolith

I just finished the first version of a new WordPress installation template called Regolith. I’ve been using my personalized fork of Mark Jaquith’s WordPress Skeleton for the past several years, but recently came across Bedrock and really liked it. I started playing around with it, but quickly discovered that the tools and practices it embraced were a bit overkill for […]

Generating Dynamic Placeholders for $wpdb->prepare()

$wpdb->prepare() is often called with each un-sanitized value explicitly passed as an individual argument; for example: $wpdb->prepare( "SELECT id FROM wp_posts WHERE id > %d AND `post_status` = %s", $min_id, $status ) The function will also accept an array of un-sanitized values, though, like this: $wpdb->prepare( "SELECT id FROM wp_posts WHERE id > %d AND […]

Logging WordPress REST API errors

I wanted a simple logger for errors in REST API requests and didn’t find one online, so I wrote this one:

Quick Navigation Interface

I just pushed a new plugin to the WordPress.org repository that lets you quickly navigate around wp-admin using just the keyboard, similar to Dash/HUD in Ubuntu or Spotlight in OS X:

Update: Version 0.2 is out now, and it’ll also include your posts, pages, and other content types in the results.

Challenging Your WordPress Assumptions from 2009

Nacin gave a great talk at php[world] dispelling a lot of the myths about WordPress that still exist in the developer community.

Flushing Rewrite Rules on All Sites in a Multisite Network

TL;DR: View the code on Meta Trac. Every once in awhile I’ll run into a situation where something will break permalinks on all the sites in a WordPress Multisite network, like a plugin network-activation gone wrong. On a single site, it’s easy enough to fix by manually visiting Settings > Permalinks, which will flush and rebuild the rewrite […]

Why Websites Get Hacked

Why Websites get Hacked is a good high-level article to sends to clients or friends who don’t understand why someone would want to attack their site — and therefore doesn’t see the need to protect it — or are curious about how it happens.
