D7 as D8

The document discusses using plugins and the plugin system in Drupal 8 to solve problems and experiment with Drupal 8 features. It describes creating a "Plug" module that provides base classes and integration to allow defining Drupal 7 plugins that emulate Drupal 8 field types, configuration entities, and other plugin types using annotations and YAML discovery. An example use case of a nonprofit billing system with custom field types and entities is also discussed. The goals are to learn Drupal 8 features, improve skills through experimentation, and have fun without costs.
![Typed Entity: Example code
1. Create the class with your custom methods
2. Use that object in your regular Drupal code
namespace Drupalmy_moduleTypedEntity;
class TypedNodeArticle extends TypedNode implements TypedNodeInterface {
function hook_drupalcamp_blow_mind($node) {
$article = TypedEntityManager::create('node', $node);
foreach ($article->getRelatedArticles() as $related) {
// $related->getImage() returns a TypedFileImage!
$image_urls[] = $related->getImage()->getUrl();
}

- 3. I came to talk about my module!
- 5. Motivations • Learn about Drupal 8 • Improve our skills • Experimentation • No need to waste free time or money • Have fun
- 6. We are not discovering sliced bread • There are already modules helping us: • X Autoload, Composer manager, Service Container • Other people is writing blog posts about this: • https://www.previousnext.com.au/tags/drupal-8-now • http://cambrico.net/drupal/using-composer-to-build-your-drupal-7- projects
- 7. Why Plugins? • Plugins are a key component in D8 • Field types, Entity types, Image effects... • D8 plugin system is Drupal agnostic (lib/Drupal/Component folder) • A lot of problems can be solved using plugins It started with basic plugins, but then it spread! We created Plug Family
- 8. Plug architecture • Packagist package created from D8 source code: drupal/d7-plugin • Download and register the package to be used via Composer manager • Plug module provides some glue code to integrate the plugin system • Register PSR-4 namespace for classes via X Autoload • Base classes to make easier the plugin creation
- 9. Plugin discovery types Annotation based plugins Plugin classes are annotated and placed in a defined namespace. Class Acme: namespace Drupalplug_examplePlugincompany; /** * @Company( * id = "acme", * country = "USA" * ) */ class Acme extends CompanyBase implements CompanyInterface {
- 10. Plugin discovery types YAML based discovery Plugins are listed in YAML files. This is mainly useful if all plugins use the same class. Class Fruit: apple: label: Apple sugar: 'low' namespace Drupalplug_examplePluginfruit; class Fruit extends PluginBase implements FruitInterface {
- 11. Plug Field • Emulate the Drupal 8 Field System • Expose Field types, widgets and formatters as annotated plugins • Provide base classes to extend easily
- 12. Plug Config • Create exportable entities as annotated plugins • Wrapper around Drupal 7 entities • Alternative to CTools plugins: • Object Oriented Plugins • Actually are entities
- 13. Typed Entity (does not need Plug) • Organize your custom code around entities in objects • Forget my_module_process_article_images($nid) • Use $article->processImage() instead • It's a very lightweight module. Can complement Plug • More re-use of code: Code is centralized & You can use base classes • Objects are easy to pass around
- 14. Typed Entity: Example code 1. Create the class with your custom methods 2. Use that object in your regular Drupal code namespace Drupalmy_moduleTypedEntity; class TypedNodeArticle extends TypedNode implements TypedNodeInterface { function hook_drupalcamp_blow_mind($node) { $article = TypedEntityManager::create('node', $node); foreach ($article->getRelatedArticles() as $related) { // $related->getImage() returns a TypedFileImage! $image_urls[] = $related->getImage()->getUrl(); } }
- 15. Use case example Somos twisters billing system • NGO fundraising company • Manage multiple non profit companies • Complex bonus system for callers • Multiple roles
- 16. Hot topics • Custom plugins for different billing calculators • Plug • Multiple custom entity types • Entity boilerplate • Custom field types for bonuses and penalties • Plug Field
- 17. Field diagram • 7 Field type classes • 1 main abstract class • 4 Interfaces • Extra features for invoicing tasks
- 18. I did it in a.module file
- 19. ...but show me the code!
- 20. Why we do love this stuff • Maintainability • Have fun learning a new way to solve problems • Investigate and discover new programming patterns • Be ready for all the new Drupal 8 coding paradigms Teamwork and give back to the community Alone we can do so little; together we can do so much Helen Keller
- 21. Conclusions • Don't need to wait more to open your mind • Try to learn new things to avoid burn out • Get out of Drupal island to learn and improve your skills Thirst for knowledge is basic to be up to date
