DrupalCamp London 2017

12th March 2017

DrupalCamp London 2017 was held on the 4th and 5th of March at the newly refurbished main hall of City, University of London. The new facilities are really nice and keep the conference in the same area, but they aren't too small that it feels cramped.

Drupal 7: Update Field Definitions For Lists

17th November 2016

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.

PHPNW 2016

6th November 2016

The 9th PHPNW was held on the 1st and 2nd of October 2016 and I was in attendance with around 400 people. The venue was the Manchester Conference Centre, which is where the event has been for the past few years. It's a nice place with helpful and friendly staff, lots of rooms, great food and even a good bar. After a quick introduction from the organizers Jeremy Coates and Rick Ogden) and a session from the platinum sponsors UKFast we started the conference proper.

DrupalCon Dublin 2016

4th October 2016

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Drupal 7: Redirect Users From Unpublished Content

9th August 2016

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feature on a Drupal site where all nodes of a certain type would redirect to a main listing page if that node had been unpublished. The problem in doing this is that if a post is unpublished then Drupal will issue an access denied response quite early on in the boot process. When the menu item is loaded it goes through an access callback which sees that the post is unpublished and issues an access denied before anything else can happen.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.

Drupal 8: Detecting An Anonymous User

28th June 2016

To find out if the current user is anonymous use the following.

\Drupal::currentUser()->isAnonymous();

This can be used as part of an if statement like this:

Drupal 8: Get The Current Language

26th April 2016

To get the currently selected language on a Drupal 8 site you need to run the following.

$language = \Drupal::languageManager()->getCurrentLanguage()->getId();

This will return the 2 character ISO language code for the language. So for English this would be "en".

To get the language name instead of the language code use this.

$language =  \Drupal::languageManager()->getCurrentLanguage()->getName();

Drupal 8: Include A Twig Template

1st April 2016

When creating re-usable theme templates in Drupal 8 it's quite easy to include that template by using the following snippet.

{% include directory ~ '/templates/parts/footer.html.twig' %}

This assumes that your footer.html.twig template file is kept in the same theme as the template you are working on. It's also good practice to add the template part to a directory called 'parts' or 'components' to separate them from the normal Drupal templates.

DrupalCamp London 2016: A Review

1st April 2016

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

16th December 2015

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.
