API and Plugins

Plugin API in Drupal 8:
drupal.org/developing/api/8/plugins

Many ways to do the same thing in Drupal 7.

Hooks

/**
 * Implements hook_mymodule_hook_info().
 */
function example_mymodule_hook_info() {
  $info['example'] = array(
    'label' => t('Example implementation'),
    'callback' => 'example_mymodule_callback',
    'settings form' => 'example_mymodule_form',
  );
  return $info;
}

CTools plugins

function example_ctools_plugin_directory($module, $plugin) {
  if ($module == 'mymodule' && $plugin == 'hook') {
    return "plugins/$module/$plugin";
  }
}

// plugins/example/hook/example_implementation.inc
$plugin = array(
  'title' => t('Example implementation'),
  'class' => 'ExampleMyModuleHookImplementation',
);

// plugins/example/hook/ExampleImplementation.class.php
class ExampleMyModuleHookImplementation {
  // Does stuff.
}

Plugins in D7

lib/MyModuleHookPluginInterface.php

interface MyModuleHookPluginInterface {
  public function getDefaultConfig();
  public function doSomething();
}

lib/MyModuleHookPluginBase.php

abstract class MyModuleHookPluginBase implements MyModuleHookPluginInterface {
  /** @var array */
  public $config;

  public function __construct(array $config = array()) {
    $this->config = $config + $this->getDefaultConfig();
  }

  public function getDefaultConfig() {
    return array();
  }

  abstract public function doSomething();
}

Plugins in D7

example.module

function example_mymodule_hook_info() {
  $info['example'] =
    'label' => t('Example implementation'),
    'class' => 'ExampleMyModuleHookPlugin',
  );
  return $info;
}

example.info

files[] = lib/ExampleMyModuleHookPlugin.php

lib/ExampleMyModuleHookPlugin.php

class ExampleMyModuleHookPlugin extends MyModuleHookPluginBase {
  public function doSomething() {
    // Do stuff!
  }
}

Plugins in D7: Invoking

function mymodule_get_hook_instance($instance) {
  $info = module_invoke_all('mymodule_hook_info');
  drupal_alter('mymodule_hook_info', $info);
  if (isset($info[$instance])) {
    return new $class($config);
  }
  else {
    throw new Exception(...);
  }
}

$results = mymodule_get_hook_instance('example')->doSomething();
