Can't upload more than 20 files using Media Image Entities in Drupal 8?

After migrating an older Drupal 6 site with 20,000 media items to Drupal 8, I found a strange problem with image uploads. On the Drupal site, using Image FUpload and Adobe Flash, I could upload up to 99 images in one go. On the new Drupal 8 site, I was only able to upload 20 images, even though I didn't see an error message or any other indication that the rest of the images I had selected through the Media Image upload form were not successfully added.

I could choose 21, 40, or 500 images, but only 20 were ever added to an album at any time.

There were no apparent warnings on the screen, so I just assumed there was some random bug in the Media Image Entity or Media module suite that limited uploads to 20 files at a time.

But due to an unrelated error, I glanced at the PHP logs one day, and noticed the following error message:

Add a set of Taxonomy terms via a custom Drupal module's update hook

From time to time, I've needed to have a default set of Taxonomy terms created at the same time as a content type, as in the case of a field with a required Taxonomy term reference, using a Taxonomy that is not 'free tag' style.

Instead of requiring someone to go in and manually add all the terms after code is deployed, you can add terms in a custom module's update hook, like so:

Upgrading Drupal VM in a BLT-powered project

Limiting the amount of surprises you get when developing a large-scale Drupal project is always a good thing. And to that end, Acquia's BLT (Build and Launch Tools) wisely chooses to leave Drupal VM alone when updating BLT itself. Updates to Drupal VM can and should be done independently of install profile and development and deployment tooling.

composer require geerlingguy/drupal-vm:~4.0

But this creates a conundrum: how do you upgrade Drupal VM within a project that uses BLT and has Drupal VM as one of it's composer dependencies? It's actually quite simple—and since I just did it for one of my projects, I thought I'd document the process here for future reference:

Interview with Cal Evans on Voices of the elePHPant

A few months ago, when I spoke at php[tek] in St. Louis, I had the honor of being interviewed by Cal Evans on the Voices of the elePHPant podcast! In the interview, we discussed Drupal 8, Acquia, the Raspberry Pi Dramble, and the PHP community.

Check out the interview: Interview with Jeff Geerling - Voices of the elePHPant.

Change the displayed username in Drupal 8 ala Realname

Recovering from surgery finally gave me time to update my last D6 site—a 7 year old private photo and media sharing site with nearly 10,000 nodes and 20+ GB of content—to Drupal 8. Drupal 8 has become a lot more mature lately, to the point where I'm comfortable building a site and not having the foundation rot out from beneath as large ecosystem shifts have mostly settled down.

One thing that I thought would have the simplest implementation actually took a little while to figure out. I needed to have users' full name display instead of their usernames throughout the site. For D6 (and for similar D7 use cases), the easiest way to do this was to enable the Realname module, configure it a tiny bit, and be done with it.

In Drupal 8, however, Realname doesn't yet have a full release (see this issue for progress), and the way usernames are generated has changed slightly (see change record hook_username_alter() changed to hook_user_format_name_alter()).

Should I disable PHP warnings and notices?

This is a reposting of what I wrote on the Acquia Dev Center blog in 2016, Should I disable PHP warnings and notices?.

Drupal onscreen logged PHP error messages and warnings

Many developers who work on Drupal (or other web/PHP) projects have error reporting disabled in their local or shared dev environments, for a variety of reasons—some don't know how to enable it, some are annoyed by the frequency of notices, warnings, and errors, and some don't like to be reminded of how many errors are logged!

There are a few important reasons you should make sure to show all errors when developing, though:

Adding a role to a user programmatically in Drupal 8

Since a quick Google search didn't bring up how to do this in Drupal 8 (there are dozens of posts on how to do it in Drupal 7), I thought I'd post a quick blog post on how you can modify a user's roles in Drupal 8. Hint: It's a lot easier than you'd think!

In Drupal 7, $user was an object... but it was more like an object that acted like a dumb storage container. You couldn't really do anything with it directly—instead, you had to stick it in functions (like user_multiple_role_edit()) to do things like add or remove roles or modify account information.

In Drupal 8, $user is a real, useful object. Want to modify the account name and save the change?

Streaming PHP - disabling output buffering in PHP, Apache, Nginx, and Varnish

For the past few days, I've been diving deep into testing Drupal 8's experimental new BigPipe feature, which allows Drupal page requests for authenticated users to be streamed and loaded in stages—cached elements (usually the majority of a page) are loaded almost immediately, meaning the end user can interact with the main elements on the page very quickly, then other uncacheable elements are loaded in as Drupal is able to render them.

Here's a very quick demo of an extreme case, where a particular bit of content takes five seconds to load; BigPipe hugely improves the usability and perceived performance of the page by streaming the majority of the page content from cache immediately, then streaming the harder-to-generate parts as they become available (click to replay):

I'm thrilled to announce that I'll be delivering two sessions at php[tek] this year:

Both topics are near and dear to me, as I've had more time to refine the Ansible roles and performance of Drupal 8 on a Raspberry Pi (see Drupal Pi and the Raspberry Pi Dramble website for more info), and I've also been spending some time lately optimizing my WFH environment (the nice cave-like office in my basement, where I spend the majority of my waking hours!).
