Creating multilingual variables

A super quick blast from the past today; a Drupal 7 based article!

I had some work recently to create a new "setting" variable for one our Drupal 7 multilingual sites, which meant creating multilingual versions of those variables. I soon found out that there is very much a correct way - or order - to achieve this as I got this one very wrong (I had to re-instate my DB!). So here I am writing a very quick guide to help those from my wrong doings.

(This guide assumes you have a multilingual site setup with i18n's Variable translation...

SA-CORE-2018-004

26th Apr 2018

As with every other Drupal agency on the planet, it was another fun evening of frantic patching of client sites last night due to the release of the highly critical SA-CORE-2018-004 security update for Drupal, released on 25/04/2018.

Being so closely related to SA-CORE-2018-002 and knowing proven exploits for that were already affecting thousands of un-patched Drupal sites, time was of the essence for this one as a new exploit was sure to be released in a matter of hours.

Our crack team of developers who stayed late especially had all of our clients' production and testing sites patched within a...

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...

Making the Flag Module's Confirmation form use AJAX

17th Apr 2012

This article discusses how we can use a combination of techniques to take the standard 'Confirmation Form' provided by the Flag module and get it to load in a modal window rather than on its own page. We'll also extend this form slightly to allow the user to include some additional data before clicking 'Confirm'. As an example we'll use the Flag module to create an 'Abuse' flag that will apply to a comment entity - this is intended to allow a user to flag a comment as requiring moderations but before triggering the actions associated with the flag we...

Render a block programmatically

22nd Mar 2012

This is a real quick one, but so useful! We often want to render a block within content, perhaps as part of a node (maybe in hook_node_view, and then made configurable like a field), but there's no obvious way to do this correctly for any block. Drupal normally renders its blocks per region, so there is no single function to embed a block. I came across this really simple solution by Damien Tournoud in a Drupal core issue, which I feel deserves more exposure:


$block = block_load($module, $delta);
$render_array = _block_get_renderable_array(_block_render_blocks(array($block)));
$output = render($render_array);

That's just three...

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.

Drupal node load references : Drupal 7

12th Jul 2011

In Drupal 6, if you called node_load then what you'd be returned would be your own copy of the node to change and modify as you pleased, but in Drupal 7 this was changed. By default, what you actually get back from a node_load is essentially a reference to a global singleton for that node. This has the interesting side effect of meaning that if you change anything in the node object, you are probably changing everyone else's copies of that node too. This is explained in this issue: http://drupal.org/node/154859

So, why should you care? Well, in the right circumstances...

Multiple conditions for dynamic forms in Drupal 7

5th Jul 2011

Here's a quick follow-up to my original post on Dynamic forms in Drupal 7, as a reply to Wappie08, who asked me about combining conditions in the #states array to add increased control over the display of your form elements.

The question:

Hi James Williams, I read your blog post about d7 & #states in the FAPI which is really cool! One problem is that the information is also listed in the drupal.org example module, I was missing one important extra hint: how can you make an IF statement?

I mean:
IF field_1 is '1' or...

Setting default drupal theme during installation : programatically install a drupal theme

25th Mar 2011

Here's a quick post that will be a reminder for us as much as anyone else! Setting the default theme during installation using an installation profile is surprisingly hard in Drupal 6, and easier though not obvious in Drupal 7. In Drupal 6, we used the wonderful Install Profile API module, which allowed us to do it in just a few lines in an install task:


  install_enable_theme(array('my_theme', 'garland', 'rubik'));
  install_default_theme('my_theme');
  install_admin_theme('rubik');

In Drupal 7, here's the code I use in my install task:


  // Any themes without keys here will get numeric keys and so will be enabled,...
