Drupal 8: Date Search Boosting With Search API And Solr Search

15th May 2018 - 8 minutes read time

The Search API Solr Search module has a bunch of controls for boosting certain fields. This allows you to give more weight (i.e. boost) to the title and less weight to the body, which means that when a search term appears in the title of a page it has more weight than a page that only has the term in the body. This weight value is ultimately used to calculate the score of the page and this directly effects the ordering of results.

Setting Up Drush Aliases And Using sql-sync

2nd May 2018 - 9 minutes read time

Drush sql-sync is a very easy way of grabbing a copy of a Drupal database from one site and installing it on another site. The normal application of this task is to copy the database from the production site to your local environment for facilitate local development. There are one or two steps to sort out before you can use the command

This post assumes you have Drush 8 installed on your machine as Drush 9 uses a different syntax for sotring Drush aliases. This also assumes that you have setup SSH key access to all servers you need to get access to.

Setting Up Aliases

The first thing you need to do is set up your Drush aliases, this allows you to connect to the remote Drupal instance from your local machine. Drush aliases are kept in your ~/.drush directory. To see what aliases you have on your system use the command.

DrupalCamp London 2018

18th March 2018 - 14 minutes read time

It's been a couple of weeks since DrupalCamp London 2018 so I thought I would try to write up my experiences for the weekend. DrupalCamp London ran from 2nd to the 4th of March and consisted of a CxO day before a 2 day conference.

Getting to the conference this year was a little more troublesome than usual. The snow and frost from that week had caused chaos on the trains (not to mention the roads) and so after many cancellations and delays I eventually made it to London the night before the Saturday/Sunday conference. The snow didn’t just affect me though, a few people couldn’t make it and a few sessions had to be rearranged. Thankfully, everyone made it to the camp in the end.

Drupal 8 : How To Avoid Block Caching

11th February 2018 - 6 minutes read time

I was struggling with a problem on a Drupal 8 project that was in development recently where a block used to show information to anonymous users was cached for the first user who saw it. This meant that the special message meant for the first user was then being seen by all subsequent users who visited that page. This only happened when page caching was turned on, but as it's best practice to do that I didn't want to turn that off just to solve one little problem.

NWDUG Unconference 2017: A Review

20th November 2017 - 10 minutes read time

For the past few months I have been organising an unconference event with †he other organisers of the North West Drupal User Group (NWDUG). An unconference is just like a normal conference, with the exception of the sessions. All of the sessions are selected on the day and then presented by the delegates. Thankfully, everything came together and on November the 4th at MadLab in Manchester we had 55 people show up for the day. Once we introduced the day and got some sessions on the wall we started out.

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 - 5 minutes read time

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.

The solution to this is to alter both the field definition and the field data via directly altering them in the database. The following function provides a neat little way of doing this to a field by just passing in the field name and what the key values need to change to.

DrupalCon Dublin 2016

4th October 2016 - 11 minutes read time

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. So this will be a few random highlights and stand out moments of the conference.

Drupal 7: Redirect Users From Unpublished Content

9th August 2016 - 5 minutes read time

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.

The solution was to use hook_menu_alter() to change the access callback parameter of the node page. We are essentially replacing the normal access callback of node_access() with our own version.

Drupal 8: Detecting An Anonymous User

28th June 2016 - 1 minute read time

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:

if (\Drupal::currentUser()->isAnonymous()) {
  // Run action.
}
