Drupal 7: Update Field Definitions For Lists

Thursday, November 17, 2016 - 18:24

I had to update a Drupal 7 site recently and needed to change the field keys of a list field to be different values. This wasn't possible from within Drupal as it does a pre-check to make sure that the key doesn't already exist. If it finds any values present in the database with that key then it will reject the change. This is absolutely correct but causes a little bit of an issue when you need to update these values.

DrupalCon Dublin 2016

Tuesday, October 4, 2016 - 23:10

The European DrupalCon was held in Dublin from 26th - 30th September and I went along with a couple of colleagues to learn a few things about Drupal. I have been back from the conference for a few days now, and I wanted to write down some of the highlights of the conference in a blog post. There is a lot going on at DrupalCon and with 2000+ people, 3 full days of sessions, 2 tutorial days, multiple parties and over 10,000 cups of coffee consumed there is too much to write about here.

Drupal 7: Redirect Users From Unpublished Content

Tuesday, August 9, 2016 - 09:54

I was recently asked to implement a feature on a Drupal site where all nodes of a certain type would redirect to a main listing page if that node had been unpublished. The problem in doing this is that if a post is unpublished then Drupal will issue an access denied response quite early on in the boot process. When the menu item is loaded it goes through an access callback which sees that the post is unpublished and issues an access denied before anything else can happen. So in this situation you can't use things like Rules to redirect users as the rule is never triggered.

DrupalCamp London, now in it's 4th year, was held of the weekend of the 4th, 5th and 6th of March at The University of London campus in London. Myself and a few other developers from Manchester headed down for the weekend to attend. I wasn't able to attend the CXO day on the 4th, but we were all in attendance for the camp event.

Overriding Drupal 7 Theme Functions In Module Files

Wednesday, December 16, 2015 - 11:23

When overriding theme functions in Drupal 7 you would normally copy the theme function into the template.php and alter it to suit your needs. This isn't always convenient though, especially if you are trying to abstract functionality into modules and not have code in your theme layer that is reliant on module code. If you add theme override functions to your module files then they won't do anything as Drupal isn't looking for them there and won't pick them up.

DrupalCamp Scotland 2015: A Review

Monday, November 9, 2015 - 16:17

DrupalCamp Scotland 2015 consisted of a Friday training day, followed by a day of talks and sessions on the 6th and 7th November.

The training day was based around Drupal 8 and had us looking at installation, configuration, and development. In the morning we set up a couple of Docker containers (on a Digital Ocean box) to run Drupal 8 from and then looked at the Drupal command line tool when setting up the system. Once installed we looked at the system structure and how the configuration management system worked. In the afternoon we created modules and themes, also using the Drupal console to generate some of the code fragments. I think the use of Docker on a remote server was a good idea in getting everyone up and running on the system without having to rely on local LAMP stacks or whatever. The training day was really good and I was able to swap lots of ideas and techniques with the trainers and other attendees.
