A/B Testing with ABJS module

5th Feb 2019

ABJS is a contrib Drupal module, and, without any requirements or ties to paid services, is as low cost as you can get. As we’ll see, it’s pretty basic but it really lets you get down to building your own understanding of how A/B testing works. The beauty of ABJS is in its simplicity. The settings pages are fairly self-explanatory, which is really helpful. Let’s set up a basic A/B test to show how things work.

Setting up our first experience

In our test, we’re going to split the site 50:50 in order to test an alternate homepage design. Go...

Review driven development?

22nd Jan 2019

We've heard of test-driven development, behaviour-driven development, feature-driven development and someone has probably invented buzzword-driven development by now. Here's my own new buzzword phrase: review-driven development. At ComputerMinds, we aim to put our work through peer reviews to ensure quality and to share knowledge around the team. Chris has recently written about why and how we review our work. We took some time on our last team 'CMDay' to discuss how we could make doing peer reviews better. Here's some of our thoughts. Many of them are essentially answers to this question: Why is reviewing hard? How can we make it easier?

Drupal 7, 8 and 9 - When to Migrate

2nd Jan 2019

Anyone familiar with the Drupal core development lifecycle will know that presently the Drupal community supports two major versions at any one time: the current major release and its immediate predecessor. This means that at ComputerMinds we are currently helping our clients support and develop both Drupal 7 and Drupal 8 sites. So the obvious question that we get asked is ‘when is it time to upgrade’?

We can’t properly answer this question without bringing the next major release, Drupal 9, into the mix. So let’s look at the development timeline for these three versions. According to a blog post...

Peer Review

2nd Jan 2019

At ComputerMinds we like to think that we’re all pretty good at what we do; however, nobody is perfect and this is why we always ensure that our code is properly peer reviewed as part of our quality assurance process.

Peer review is literally just what the name implies; we work together to review each other’s code to make sure that it all makes sense. This approach means that we’re able to spot obvious mistakes before they become a problem. It also has the huge advantage of allowing us to transfer knowledge between our team on a day-to-day basis.

Custom AJAX loading icon

18th Dec 2018
There's nothing like Drupal's default spinning blue AJAX animation to make you notice that a site's design hasn't been fully customised. The code from my previous article showing how to fetch a link over AJAX to open in a Foundation reveal popup would suffer from this without some further customisation. After clicking the 'Enquire' button, a loading icon of some kind is needed whilst the linked content is fetched. By default, Drupal just sticks that blue 'throbber' next to the link, but that looks totally out of place. Our client's site uses a loading graphic that feels much more appropriate in style and placement, but my point is that you can set up your own bespoke version. Since it's Christmas, let's add some festive fun!

Security risks as Drupal matures

12th Dec 2018

After reading this from Ars Technica, which describes how a developer offered to 'help' the maintainer of an NPM module - and then slowly introduced malicious code to it - I can't help but wonder if the Drupal community is vulnerable to the exact same issue. Let's discuss!

Please, don't touch my package

NPM modules have been hacked at before, and it's not pretty when it happens. Because of the way we use packages, it's a lot easier for nasty code to get sucked in to a LOT of applications before anyone notices. Attacks on the code 'supply chain', therefore,...

Open links in popups with Foundation

4th Dec 2018

Let me take you on a journey. We'll pass by Drupal content renderer services, AJAX commands, javascript libraries and a popular front-end framework. If you've only heard of one or two of those things, come lean on the experience I took diving deep into Drupal. I'm pleased with where my adventure took me to, and maybe what I learned will be useful to you too.

Here's the end result: a contact form, launched from a button link in the site header, with the page beneath obscured by an overlay. The form allows site visitors to get in touch from any...

Beware File::getFileUri()!

9th Nov 2018

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().

Consider the following code excerpt :

$file = File::load($some_file_uri);

if ($file) {
  $uri = $file->getFileUri();
  $file_realpath = \Drupal::service('file_system')->realpath($uri);
}

Seems pretty harmless right? Load up the file from $some_file_uri , If we have a valid file then get the URI and then grab the real path.

Wrong (potentially, depending on what you do with $file_realpath).

If $file is a valid file, but for whatever reason the file is...

Quickly update Drupal core

18th Oct 2018

If you've got a Drupal site, which you need to update quickly (for example, to address last night's security advisory!), here's a tip. Run this from the command line:

curl 'https://github.com/drupal/drupal/compare/7.59..7.60.patch' | patch -p1

This assumes your codebase was on Drupal 7.59 and you're currently in Drupal's root directory. If you're currently on a different version, adjust the numbers in the patch URL accordingly.

Don't forget to still run database updates via /update.php or drush updatedb !

The Drupal repo on github is a verbatim mirror of the official Drupal repo from git.drupal.org. Github supports comparing arbitrary git references,...

Localising dates in twig templates

14th Aug 2018

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 be down to the twig filter being used in the template to format the date. This is what we did have:

{% set newsDate = node.getCreatedTime|date('j F Y') %}
{% trans %} {{ newsDate }}{% endtrans %}

So this would produce something like '1 March 2018' instead of '1 März 2018' when in German....
