Language lessons: What are you translating?

19th Aug 2014

Content (node-level) translation or entity (field-level) translation?

It seems an obvious question to ask, but what are you translating?

The tools exist to translate just about anything in Drupal 7*, but in many different ways, so you need to know exactly what you're translating. Language is 'a first-class citizen', in the sense that any piece of text is inherently written by someone on some language, which Drupal 7 is built to recognise. Sometimes you want to translate each & every individual piece of text (e.g. at the sentence or paragraph level). Other times you want to translate a whole page or section that is made up of multiple pieces of text.

Drupal 8: Creating a custom field - Part 3: Field formatter

11th Feb 2014

This is part 3 in my series of articles about creating a custom field. I recommend reading Part 1: Field type and Part 2: Field widget first, if you have not done so already.

After creating the field type and field widget it is now time to complete the set by creating the field formatter.

a) Create the file

The field type must be located as follows:
<module_name>/lib/Drupal/<module_name>/Plugin/field/formatter/<field_formatter_name>.php
N.B. The field formatter name should be in CamelCase.

b) Add Contains, namespace and use

In the newly created field type file add a brief comment to explain what it...

Drupal 8: Creating a custom field - Part 2: Field drupal widget

4th Feb 2014

This is part 2 in my series of articles about Drupal widgets, and specifically creating a custom field. I recommend reading Part 1: Field type first, if you have not done so already.

After creating the field type it is now time to create the field widget.

a) Create the file

The field widget must be located as follows:
/lib/Drupal//Plugin/field/widget/.php
N.B. The field widget name should be in CamelCase.

b) Add Contains, namespace and use

In the newly created field type file add a brief comment to explain what it consists of:

Drupal 8: Creating a custom field - Using a custom field

31st Jan 2014

Having written articles on how to create a Drupal 8 field type, field widget and field formatter I thought that now is the time to explain why you might want to create a custom field type. More specifically, why I have created a custom field.

To provide some context: my pet Drupal 8 project is to produce a companion site for players of the Fantasy Football (soccer) game Fantasy Premier League (N.B. this is not my site :) ). For the uninitiated, Fantasy Football, as described by Wikipedia, is "a game in which participants assemble an imaginary team...

Drupal 8: Creating a custom field - Part 1: Field type

28th Jan 2014

I have been experimenting with the Alpha release of Drupal 8 and so I'm sharing some of my experiences so that you can avoid the pitfalls I have encountered.

First I would like to give credit to the two articles I used during the exercise:

Hopefully this article will provide a third point-of-view to make your task easier.

a) Create the file

In D8 the location of files is very important. The field type must be located as follows:
/lib/Drupal//Plugin/field/field_type/...

Place blocks inside your content with EBA

13th Jan 2014

Previously on this website I have written about rendering blocks programmatically and adding things to content to be managed alongside fields. It's time to combine the two! On many projects, we find ourselves needing to render a block consistently across all content of a certain type. For example:

  • Are you trying to place advertising blocks or fixed javascript code between the fields in the content of a page, not just shoved into regions around the content?
  • Do you want to show a standard piece of content (we use the bean module for enhanced content in blocks) to be placed...

Custom add another

6th Mar 2012

Drupal 7 fields are great, but using multiple valued fields and field collection you can quickly reach the point of having a form that looks like this:

A complex field collection form

In this contrived example I've got two field collections and a multi-valued 'Links' field within that.

Although it's reasonably clear what clicking 'Add another item' will do in each case, when the form is full of data it can become less so.

We can give content editors a helping hand by changing the buttons from 'Add another item', to something more useful like 'Add another carousel item' etc. With the Custom add another...

Add stuff to a node and configure it like fields

28th Feb 2012

We often want to add things to the content of a node or any other entity in Drupal 7 using hook_node_view(), hook_node_view_alter() or a similar hook in a custom module. This could be anything from a custom social media link, a field rendered in a custom way, additional author information or virtually anything else.

The rendered node with our pseudo-field

Here's the code used to add that Facebook like button:


/**
 * Implements hook_node_view().
 *
 * Adds a Facebook like button to page nodes.
 */
function MYMODULE_node_view($node, $view_mode, $langcode) {
  switch ($node->type) {
    case 'page':
      $node->content['MYMODULE_fb_like'] = array(
        '#type' => 'item',
        '#title' => t('Like...

Rendering Drupal 7 fields (the right way)

Drupal 7 brought us Entities, and with them the powerful Field API for 'storing, loading, editing, and rendering field data.' attached to them. If you're managing everything through 'manage fields' and 'manage display' tabs of your content type, then every part of that process is rather wonderfully taken care of for you.

We often, however, come across the need to render a field outside the context of it's entity. A common example might include rendering a node's author in a sidebar block. Sure, modules like Panels and CCK Blocks will do this for you, but doing it manually is actually not that hard.

Changing Display Suite fields in update hooks

10th Feb 2011

We've been using Display Suite with Node displays on one of our latest sites. It was an experiment, and possibly not something we'll do again - DS offers some great functionality with build modes and ways to re-arrange fields and all sorts on nodes, but since we end up theming most nodes quite a lot anyway, it's not worth the extra hassle that Display Suite can add when you want to change the theming on DS fields, layouts, change the fields' settings etc...

We use update hooks to change most things on sites for clients, since this allows us to...
