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

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

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

Object-Oriented PHP Example menu_block/lib/Drupal/menu_block/MenuBlockRepository.php

Dependency Injection http://www.sxc.hu/photo/778753

Dependency Injection page_example/lib/Drupal/page_example/ExampleService.php

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

Routing Pages and Forms http://pixabay.com/en/road-sign-arrows-arrow-direction-64060/

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

D7 Hook Menu

D7 Hook Menu

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

2. Create a Controller class page_example/lib/Drupal/page_example/Controller/PageExampleController. php

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

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) $this->moduleHandler()->moduleExists ($m)

Controller DI Factory Pattern

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

Form Example

What happened to hook_menu()? (sad face)

Default Menu Links hook_menu_link_defaults()

Local Actions module .local_actions.yml

Local Tasks module .local_tasks.yml

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

Configuration System http://www.sxc.hu/photo/425946

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

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

Configuration System system_settings_form() is gone Instead subclass ConfigFormBase Example: @see \Drupal\system\Form\SiteInformationForm

Configuration System Ctools exportables => Config Entities

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

Configuration System Module config imported on install Docs https://drupal.org/node/1667894

Configuration System Deployment workflows Active => Staging => Active

Configuration System Translatable in core Schemas for validation

Plugins

Plugins Learn plugins once - apply it everywhere

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

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

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

Blocks

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

Plugins So many more Learn Once Apply Everywhere More: http://bit.ly/1a50ygs *Stream wrappers still pending Image created with taxedo.com

Entities and Fields http://www.sxc.hu/photo/1433343

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

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

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

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

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

Entities and Fields Info Discovery API $entity->getPropertyDefinitions() $entity->field_foobar->getFieldDefinition() @see Drupal\Core\Field\FieldDefinitionInterface

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

Twig example

There’s a session for that... “Can I TWIG It? Yes, You Can!” Sunday 11:30am mortendk

theme() is deprecated Instead: Return render arrays with a #theme item

#theme example

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

Library Info Hook
