Beware File::getFileUri()!
I'll keep this short and sweet, but we thought this would be a useful tip to share with the world as a potential security issue with the combined use of File::getFileUri() and FileSystem::realpath().Read article →Quickly update Drupal core
Update: this article's suggested method has serious shortcomings, use other methods when you can! For example, run the following with drush to just upgrade drupal core code (leaving database updates to be run separately):Read article →Localising dates in twig templates
A client noticed the dates on their news articles were not being translated into the correct language. The name of the month would always appear in English, even though all the month names had themselves been translated and showed correctly elsewhere. The problem turned out to…Read article →Keeping dynamic HTML classes easy to find
I imagine many of us have been there: there’s some CSS class in your markup, and you need to do something with it. Maybe you want to remove it, change it, or perhaps alter its style declarations. “Easy peasy,” you think, “I’m a developer. I got this.” And so you should.Read article →Including form values in an email
Let's say you've built a custom form for your Drupal 8 site. It contains various elements for input (name, email address, a message, that kind of thing), and you want to send the submitted values in an email to someone (perhaps a site admin). That's a pretty common thing to…Read article →Rebranding ComputerMinds - Part 6: Migration
I volunteered to carry out the migration for the new ComputerMinds site as migration was one of the very few areas of Drupal that I hadn’t delved into thus far. With Drupal 8 becoming more and more popular, now was a great opportunity to learn the migration ropes. Luckily,…Read article →Rebranding ComputerMinds - Part 5: Development
Let's have a quick look through our development process on this project and pick out some of the more interesting bits. As briefly mentioned in the last article we are using a composer set up and all code is version controlled using git on github. All pretty standard stuff.Read article →GDPR compliance steps for Drupal Developers
The new GDPR laws are here, hurrah!Read article →Got a config schema error on saving a view?
We ran into an obscure error recently, when saving a view that used a custom views plugin. It was supposed to be a very simple extension to core's bundle (content type) filter:Read article →Creating multilingual variables
A super quick blast from the past today; a Drupal 7 based article!Read article →Rebranding ComputerMinds - Part 4: Pattern Lab
We didn’t see this project solely as a chance to rebrand and rebuild for ourselves, it was also an opportunity to try something new and expand our collective knowledge with the potential for using with clients in the future. We had been discussing using Pattern Lab for Front…Read article →Rendering Drupal fields (the right way)
Once upon a time, we wrote an article about how to render fields on their own in Drupal 7, which was really handy because Drupal 7 wasn't always intuitive. It's common to want to display a field outside of the context of its main entity page, like showing author information in…Read article →Fixing Drupal, really quickly
Drupalgeddon2 happened! We got all but two of our projects updated within an hour, with those remaining trickier two fully patched another hour later. The key was planning the right process using the right tools. We actually use these tools for regular deployments every day,…Read article →Patching Drupal without server access
If you don't have access to the file system on the server for a Drupal site, when a security issue like Drupalgeddon2 comes along, you are entitled to panic! Many sites are run by a combination of teams, so sometimes you really don't have control over the server... but that…Read article →Class naming for Javascript development in Drupal
We've settled on what we think is a best practice for class naming for Javascript in Drupal – let me explain what I mean and then talk you through our reasoning.Read article →Render a Drupal 9 View programmatically (Render arrays FTW!)
Extra quick tip for developers working with Drupal 8 or 9: Adding views to your page content is now incredibly straightforward:Read article →Aegir is ten!
Ten years ago today Adrian Rossouw committed the first code for the Aegir project. ComputerMinds have been involved in Aegir for many of those years, particularly one of our senior developers: Steven Jones. We asked him some questions about it to mark the occasion.Read article →Get the entity for a route
In Drupal 7, we had menu_get_object() to get the object in code for whichever node, term, or whatever entity makes up the current page. But in Drupal 8, that has been replaced, and entities can usually be operated on in a generic way. If you know the type of entity you want,…Read article →Help Drupal help your configuration
TL;DR: Define a schema for any bespoke configuration, it's not too hard. It's needed to make it translatable, but Drupal 8 will also validate your config against it so it's still handy on non-translatable sites. As a schema ensures your configuration is valid, your code, or…Read article →Drupal as a Server - Introduction
This post is the first in a series about getting Drupal to run as a persistent server, responding to requests without bootstrapping each and every time.Read article →Show elements with form #states when values do not match
I've previously written about dynamic forms in Drupal, using #states to show or hide input boxes depending on other inputs. Since then, Drupal 7 and 8 have both got the ability to combine conditions with OR and XOR operators. This makes it possible to apply changes when a form…Read article →Loading config programmatically
In Drupal 8, there are many ways to interact with configuration from PHP. Most will allow you to write the config values, but some are read-only. Some will include 'overrides' from settings.php, or translations. There are many layers of abstraction, that each have different…Read article →Commands I use when creating a patch for drupal.org
Over the past couple of years I have become more active in issues on drupal.org, in which time I have honed a selection of commands that I regularly use in the creation and application of patches. Here is a run-down of my most useful commands.Read article →Replacing a vocabulary listing
In a recent Drupal 8 project, one of the site's vocabularies had several thousand terms in it (representing airports), which caused its admin listing page to run out of memory before it could render. I wanted to solve this without affecting any other vocabularies on the site,…Read article →Let's talk
