5. Configuration Management

6. Front-end developer improvements

HTML5 Forms

PHPTemplate is now Twig7.x: page.tpl.php 8.x: page.html.twig

<div id="page-wrapper"> <div id="page"> <div id="header"> <div class="section clearfix"> <?php if ($logo): ?> <a href="<?php print $front_page; ?>" title="<?php print t('Home'); ?>" rel="home" id="logo"> <img src="<?php print $logo; ?>" alt="<?php print t('Home'); ?>" /> </a> <?php endif; ?>

<div class="layout-container">   <header role="banner"> {% if logo %} <a href="{{ front_page }}" title="{{ 'Home'|t }}" rel="home"> <img src="{{ logo }}" alt="{{ 'Home'|t }}"/> </a> {% endif %}

• Friendlier syntax for designers • Variables auto-escaped for better security

No more (core) support forIE 6, 7, & 8

7. Web Services

8. Modern, OO Code

Warning: Things are about to

get... geeky.

"Getting off the Island"

Modern PHP Best Practices• PHP 5.4+

• Classes/Interfaces

• Namespaces

• Traits

• Dependency Injection

• Most PSR-* standards

Powered by Symfony2

…and dozens of other "best of breed" libraries

…and dozens of other librariesA peek under the hood

YAML, YAML everywhere7.x: example.info 8.x: example.info.ymlname = Example description = "Example module" core = 7.x files[] = example.test config = admin/config/example dependencies[] = node

name: Example type: module description: "Example module" core: 8.xconfig: admin.example dependencies: - node

• New required "type" property • No more files[] (we'll get to that later) • Paths now have machine names to

help prevent breakage(we'll get to that later, too)

Drupalism: Kinda-Sorta-INI-Like

"Proudly Invented Elsewhere": YAML

Pages, forms, blocks, etc. are now all object-oriented.

"Hello World" in Drupal 7

function example_menu() { $items['hello'] = array( 'title' => 'Hello world', 'page callback' => '_example_page', 'access callback' => 'user_access', 'access arguments' => 'access content', ); return $items; }   function _example_page() { return t('Hello world.'); }

example.module

Drupalism: "ArrayPIs" ;)

"Hello World" in Drupal 8example.hello: path: '/hello' defaults: _content: '\Drupal\example\ExampleController::hello' requirements: _permission: 'access content'

example.routing.yml

<?php   namespace Drupal\example;   use Drupal\Core\Controller\ControllerBase;   /** * Returns responses for Example module routes. */ class ExampleController extends ControllerBase { public function hello() { return new Response($this->t('Hello world.')); } }

src/ExampleController.php "Proudly Invented Elsewhere":

- YAML- PSR-4 Class Autoloader

- OO code

Defining a block: 7.xexample.module<?php function example_block_info() { $blocks['example'] = array( 'info' => t('Example block'), ); return $blocks; } function example_block_view($delta = '') { $block = array(); switch ($delta) { case 'example': $block['subject'] = t('Example block'); $block['content'] = array( 'hello' => array( '#markup' => t('Hello world'), ), ); break; } return $block; }

Drupalism: "Mystery Meat" APIs based on naming conventions

Defining a block: 8.x<?php

namespace Drupal\example\Plugin\Block;

use Drupal\block\BlockBase;

/** * Provides the Example block. * * @Block( *  id = "example", *  admin_label = @Translation("Example block"), * category = @Translation("Example") * ) */ class ExampleBlock extends BlockBase { public function build() { return array('hello' => array( '#markup' => $this->t('Hello world.') )); } }

src/Plugin/Block/ExampleBlock.php

- Annotations - APIs defined by

Interfaces

Answers To Your Burning Drupal 8 Questions!

When will Drupal 8 be released?

When is "when it's ready"?

Sometime after this graph hits zero.

https://www.drupal.org/drupal-8.0/get-involved

What's left in that list?

• Performance fixes/improvements

• Security fixes/improvements

• Beta-to-beta upgrade path

• Future-proofing (PHP7, Symfony 3, etc.)

beta -> rc -> 8.0.0• While count of critical issues >

0, create monthly beta releases (we are here!)

• If critical issues === 0, start bi-weekly release candidates (same as D6/D7 release windows) • Only critical fixes or extremely

non-disruptive (e.g. docs) patches committed during RC, to prevent regressions.

• Once count, rate, and nature of criticals seem manageable, set a release date >= 3 weeks later.

“WHEN IT’S READY”

What happens after 8.0.0?• Drupal 6 support dropped 3 months

after Drupal 8.0.0's release.

• Bug fix/security releases continue on monthly schedule as now in D6/D7.

• New "feature releases" of Drupal 8 every 6 months (8.1.x, 8.2.x…) with non-BC breaking improvements.

• Drupal 9 not branched until much later, when there's enough "meat" (completed change proposals which can't be committed to 8.x) to make a compelling product

• Drupal 8 enters "LTS" mode (security fixes only) after Drupal 9.0.0

D6 SUPPORT ENDS

8.2.08.1.0

NEW FEATURES

What about upgrades?• Upgrade path between 8.x versions

• Not supported in core yet; see https://www.drupal.org/project/head2head in contrib for now

• Migration path between major versions (6/7 => 8)

• Build out your Drupal 8 site as a new site, then migrate content, users, etc. over.

• Drupal 6 => 8 migrations already in! Drupal 7 => 8 migrations are in progress.

• Must port your own custom code; stick with well-used contrib modules if you can!

When can I use D8?

Some early adopters are already using it…
