Drupal Views is a great way of exposing data to users via a search interface. This can be done directly via the database or via a Solr server. Plenty of Views plugins exist to allow reacting to the search input and output in a variety of different ways.

The other day I needed to add a personalised message to Views output to inform a user that their search keyword didn't find any results. There is a plugin for Views that allows this, but it only shows a basic search string.

DrupalCamp London was held on the 14th and 15th March 2020 and I went down to City University London to partake in the event. I wasn't talking this year, so I was there purely to enjoy the conference.

Upon a recommendation from someone in my local Drupal user group I decided to give Tailwind CSS a go. The ultimate aim of this was to replace the base theme I am using here with a more stripped down theme. At the time of writing this I am using the Cog theme, and whilst it has it's merits, I find that it's a little too much for this simple site.

I decided, therefore, to create a new theme and use Tailwind CSS to alter the site a little. This meant an exercise in integrating Tailwind CSS into a Drupal theme.

Tests for programmers in an interview process are not uncommon. For the last couple of years I have asked a quick pre-interview question to junior developers to see what sort of stuff they come up with.

As I don't want to set any developer a task that will take longer than absolutely needed I opted to set a very simple task for them. Commonly known as "FizzBuzz", this task is as follows.

One technique I find useful, especially when drawing images, is to invert a number on a scale. In PHP, coordinates in an image are drawn from the top left of the image. This means that if we want to draw from the bottom left then we need to invert the y coordinate.

The following is example PHP code that creates an image with a single, diagonal line, drawn across the middle.

Whilst searching for an answer to a problem the other day I found a comment that details a command that prints out all of the FieldWidgets available in Drupal 8. This is useful if you are looking for all of the field widget classes in Drupal8.

Here is the command:

The other day I was conducting a code review and found that a developer had used a trait to give two classes the same group of utility methods. Whilst there was nothing wrong with this in terms of functionality, I asked the developer why they had chosen to use traits instead of inheritance. We eventually decided that an inheritance model would be better suited to the situation but I thought I would go through some of the thought processes here.

What Is A Trait?

I perform a lot of Drupal updates, and they mostly go very well. The code updates without incident and the database updates apply whatever updates they need without a hitch. Every now and then, however, I will come across a project that hasn't received updates in a while, which means there are a lot of database updates to run through.

Having Drupal run 100+ database updates across modules and core can be a bit problematic. Some modules will require core updates to happen first, and when this happens out of order the database update update fails spectacularly.
