怎样编写Drupal 8模块

此文章已过时，Drupal 8的API已修改，请参考examples/page_example

Drupal 8约定把所有自定义的模块都放在了根目录下的modules了，创建自己的模块先创建如下目录：modules/foobar，里面包含文件foobar.module和foobar.info.yml。foobar.info.yml内容如下：

name: Foobar

type: module

description: 'This is a demo for creating Drupal 8 modules.'

package: Custom

version: 8.x-1.0

core: 8.x

dependencies:

- node

- block

hidden: false

<?php

 

namespace Drupal\foobar\Controller;

 

use Drupal\Core\Controller\ControllerInterface;

use Symfony\Component\DependencyInjection\ContainerInterface;

 

class FoobarController implements ControllerInterface {

 

  public static function create(ContainerInterface $container) {

    return new static($container->get('module_handler'));

  }

 

  /**

  * This will return the output of the foobar page.

  */

  public function foobarPage() {

    return array(

      '#markup' => t('This is the demo foobar page.'),

    );

  }

}

foobar:

pattern: 'admin/foobar'

defaults:

  _content: '\Drupal\foobar\Controller\FoobarController::foobarPage'

requirements:

  _permission: 'access administration pages'

<?php

 

/**

* Implements hook_menu().

*/

function foobar_menu() {

  // The paths given here need to match the ones in foobar.routing.yml exactly.

  $items['admin/foobar'] = array(

    'title' => 'Foobar',

    'description' => 'This is the demo foobar page.',

    // The name of the route from foobar.routing.yml

    'route_name' => 'foobar',

  );

  return $items;

}
