Objectives We want to add on a node page layout a block which uses a field from the currently rendered content (node). We want this block to be translated the same as the currently rendered entity. As a anonymous user, we want it to respect the published settings of the currently rendered entity. As an […]

public function controllerCallbackExample() { return [ '#type' => 'table', '#caption' => 'This is a caption. Use a translated string here.', '#header' => [ 'Header 1', 'Header 2', 'Header 3', 'Header 4' ], '#rows' => [ [ 'Row 1 Cell 1', 'Row 1 Cell 2', 'Row 1 Cell 3', ['data' => 'Row 1 Cell 4'] ], [ 'class' => ['second-row-class', 'may contain spaces but dont use them'], 'data' => [ 'Row 2 Cell 1', [ 'data' => 'Row 2 Cell 2' ], [ 'colspan' => 2, 'data' => 'Row 3 Cell 3 & 4', 'style' => 'background-color: pink; text-align: center' ] ], 'style' => 'font-weight: bold' ], [ 'data' => [ 'Row 3 Cell 1', 'Row 3 Cell 2', 'Row 3 Cell 3', 'Row 3 Cell 4' ], 'no_striping' => FALSE // Not working in 8.2.x, may be fixed later ] ], '#footer' => [ [ 'data' => [ 'Footer 1', [ 'colspan' => 2, 'data' => 'Footer 2 with colspan = 2', 'style' => 'text-align: inherit' ], [ 'data' => 'Footer 4', 'style' => 'text-align: inherit' ] ], 'style' => 'text-align: center' ], [ [ 'colspan' => 4, 'class' => 'second-footer-row', 'data' => 'Another Footer Line', 'style' => ['background-color: purple;', 'text-align: center;', 'color: white;'] ] ] ] ]; } |
Additional Information Tested to work on Drupal 8.2.x. For some reason, no_striping doesn’t work as expected in 8.2.x (it is ignored). The script which handles the render array conversion to twig ready variables is located here: core\includes\theme.inc. The twig template which renders the table on the default theme is here: core\themes\classy\templates\dataset\table.html.twig.
[Drupal] Create an event subscriber
Instructions I will be creating a dedicated module using Drupal Console for this event subscriber. But feel free to use your own if you already have one! (don’t forget to backup) Access the drupal root folder in command line. Generate a new module:

[Drupal] Service dependency injection in a service type class

services: my_module.event_subscriber: # Your service class class: Drupal\my_module\Entity\EventSubscriber\MyModuleSubscriber # Add your services to load here in the array arguments: ['@current_user'] tags: # For this example, I am making an event subscriber class - { name: event_subscriber } |

<?php namespace Drupal\my_module\Entity\EventSubscriber; use Drupal\Core\Session\AccountProxy; use Symfony\Component\EventDispatcher\Event; use Symfony\Component\EventDispatcher\EventSubscriberInterface; use Symfony\Component\HttpKernel\Event\GetResponseEvent; use Symfony\Component\HttpKernel\KernelEvents; class MyModuleSubscriber implements EventSubscriberInterface { /** * Current user service. * @var AccountProxy */ protected $currentUser; public function __construct(AccountProxy $current_user) { // Reference the current_user service $this->currentUser = $current_user; } static function getSubscribedEvents() { // Stuff related to events subscribing in Drupal $events[KernelEvents::REQUEST][] = ['kernel_request']; return $events; } /** * @param GetResponseEvent $event */ public function kernel_request(Event $event) { // Do stuff here, using $this->currentUser } } |
Additional Information Declare the services your class will use in the .services.yml file of your module. Unlike plugin type class service dependency injection, there is no create method to define the needed services. The __construct signature needs to respect the declared arguments from the .services.yml file. Originally made and tested on […]
Mini point sur ma carrière
J’ai quittĂ© volontiers l’industrie du jeu vidĂ©o, ayant perdu toute motivation d’y travailler. L’entreprise dans laquelle j’avais passĂ© plus de quatre ans Ă essayer de produire des jeux et des applications est sur le point de fermer dĂ©finitivement. Un chapitre de ma vie est en train de se clore, j’imagine. Avais-je dit que j’Ă©tais rentrĂ© […]
