2 So you want to start a pony stud small horses, big hearts

3 Drupal 8 - in a nutshell Learn Once - Apply Everywhere* Source: *Including outside Drupal

4 Major Architectural Changes

5 Don t be afraid...

6 "If you learnt php from Drupal - Drupal 8 will teach you modern php from a familiar setting" - Me, 2014

7 Proudly invented elsewhere Installed with Composer: easyrdf/easyrdf symfony2/{various} symfony-cmf/routing zendframework/zend-feed guzzle/http doctrine/annotations...

8 Modern PHP PHP 5.4+ Object-oriented PHP Classes, Interfaces, Namespaces PSR-0, PSR-4

9 Object-Oriented PHP Example menu_block/lib/drupal/menu_block/menublockrepository.php

10 Dependency Injection

11 Dependency Injection page_example/lib/drupal/page_example/exampleservice.php

12 Dependency Injection Container Symfony2 component Steps: 1. Write a class 2. Define it as a service in *.services.yml

13 Dependency Injection Container page_example/page_examples.services.yml

14 Extension points Plugins Modules Services

15 Routing Pages and Forms

16 Routing Pages and Forms What does D7 hook_menu really do? routes default menu items local actions local tasks

17 D7 Hook Menu

18 D7 Hook Menu

19 Routing Pages 2 easy steps: 1. create a PHP class that extends ControllerBase 2. create route definition in module_name. routing.yml

20 2. Create a Controller class page_example/lib/drupal/page_example/controller/pageexamplecontroller. php

21 1. Create a route definition page_example/page_example.routing.yml

22 ControllerBase Goodies D7 D8 t( some text ) $this->t( some text ); l( title, $path) $this->l( title, $route_name); url($path) $this->url($route_name); drupal_goto($path) $this->redirect($route_name); global $user $this->currentuser(); variable_get($key) $this->config( group )->get($key); cache_get($key) $this->cache()->get($key); module_exists($m) ($m) $this->modulehandler()->moduleexists

23 Controller DI Factory Pattern

24 Routing Forms 2 steps: 1. create a form class that extends FormBase 2. create route definition in module.routing.yml

25 Form Example

26 Form Example

27 What happened to hook_menu()? (sad face)

28 Default Menu Links hook_menu_link_defaults()

29 Local Actions module.local_actions.yml

30 Local Tasks module.local_tasks.yml

31 Other formats? Leveraging request accept headers Ajax controller Dialog controller REST Request uri Accept header Response node/1 application/hal+json The node in hal+json node/1 text/html The node page node/1 application/vnd.drupal-modal The node in a modal

33 Configuration System

34 Configuration System variable_{get,set} are gone! Config is stored in yaml files sites/default/files/config_{hash}/{active,staging}

35 Configuration System $config = \Drupal::config('forum.settings'); $vocabulary = $config->get('vocabulary'); $config->set('vocabulary', 'hooha')->save(); In OO code, inject service

36 Configuration System system_settings_form() is gone Instead subclass ConfigFormBase \Drupal\system\Form\SiteInformationForm

37 Configuration System Ctools exportables => Config Entities

38 Configuration System Unified Entity API including config $node_type = $storage_controller->create($values); $node_type->save(); $node_type->label(); $node_type->id();

39 Configuration System Module config imported on install Docs

40 Configuration System Deployment workflows Active => Staging => Active

41 Configuration System Translatable in core Schemas for validation

42 Configuration System State (Key/Value) API Settings API

43 Plugins

44 Plugins Learn plugins once - apply it everywhere

45 Plugins Semi-random magic collection of hooks Real objects and interfaces

46 Drupal 7 Block function forum_block_info() function forum_block_save() function forum_block_configure() function forum_block_view()

47 Drupal 8 Block Steps: 1. Create a new PHP class 2. Add some annotations

48 Blocks

49 Plugins Advantages: Base classes Inheritance One file per plugin Nice. Neat. Tidy.

50 Plugins So many more Learn Once Apply Everywhere More: *Stream wrappers still pending

51 Migrate in core Sunday 10:30am chx

52 Entities and Fields

53 Entities and Fields First class objects Swappable classes Common API No more of this crap $node->field_foo[language_none][0]['value']

54 Entities and Fields New field types Link Comment Date Entity Reference Telephone

55 Entities and Fields Display and form modes Base field consistency Fieldable blocks

56 Entities and Fields Now plugins: Field types Field formatters Widgets

57 Entities and Fields Unified API using first-class objects. D7 : $node->field_foo[language_none][0]['value'] D8: Node->title->value Node->field_foo->value

58 Entities and Fields Info Discovery API $entity->getpropertydefinitions() Drupal\Core\Field\FieldDefinitionInterface

59 Frontend

60 Twig node.tpl.php -> node.html.twig Simple Safe

65 drupal_add_js/css() removed No Javascript will be loaded by default Steps: 1. Declare assets with hook_library_info() 2. #attach your library in a render array
