Drupal 7 Bundle by Ekino

Requires at least Drush 5.0 for compatibility with Symfony console.

The bundle tries to deeply integrate Symfony2 with Drupal and Drupal with Symfony2. Of course this is done without altering the Drupal's core.

When this bundle is activated, the Symfony2 console will have the Drupal libraries autoloaded. So, it makes possible the use of Drupal libraries from your Symfony2 command.

Install

Download the symfony2 sandbox and the Drupal code

Install the files to have the following structure

Symfony Sandbox Root
  - app
  - vendor
  - src
  - web (Drupal source code)

The web directory must be the document root and contains the Drupal source code.

Update the index.php file

This file "share" the container with Drupal so it is possible to reuse Symfony2's services from within Drupal. The initialization process is always handled by Symfony2.

<?php
require_once __DIR__.'/../app/bootstrap.php.cache';
require_once __DIR__.'/../app/AppKernel.php';
//require_once __DIR__.'/../app/bootstrap_cache.php.cache';
//require_once __DIR__.'/../app/AppCache.php';

use Symfony\Component\HttpFoundation\Request;

$kernel = new AppKernel('dev', true); //
$kernel->loadClassCache();
$kernel->boot();

// make the Symfony container available from Drupal file
global $container;

$container = $kernel->getContainer();

$request = Request::createFromGlobals();

$response = $kernel->handle($request);
$response->send();

$kernel->terminate($request, $response);

Install the related Drupal module

The module can be downloaded from the following url: https://github.com/ekino/ekino_drupal_symfony2

Configuration

Edit the Symfony config.yml file and add the following lines:

parameters:
    session.flashbag.class:       Ekino\Bundle\DrupalBundle\Port\DrupalFlashBag
    session.attribute_bag.class:  Ekino\Bundle\DrupalBundle\Port\DrupalAttributeBag

framework:
    # ... configuration options
    session:
        # ... configuration options
        storage_id:     ekino.drupal.session.storage

ekino_drupal:
    root:          %kernel.root_dir%/../web
    logger:        ekino.drupal.logger.watchdog
    strategy_id:   ekino.drupal.delivery_strategy.symfony
    # attach a security token to the following provider keys
    provider_keys: [main, admin]

    # not required
    entity_repositories:
        # 3 equivalent examples of configuration:
        - { bundle: page }
        - { type: node, bundle: page }
        - { type: node, bundle: page, class: Ekino\Bundle\DrupalBundle\Entity\EntityRepository }
        # you can also define an entity repository:
        - { type: node, class: Application\Ekino\Bundle\DrupalBundle\Entity\Node\NodeRepository }

    # switch to true if you want to prefix the name of Symfony tables
    table_prefix:
        enabled: false
        prefix:  symfony__
        exclude: [users]

    # optional
    session:
        refresh_cookie_lifetime: true # default value: false

# declare 2 required mapping definition used by Drupal
doctrine:
    dbal:
        driver:   %database_driver%
        dbname:   %database_name%
        user:     %database_user%
        host:     %database_host%
        port:     %database_port%
        password: %database_password%
        charset:  UTF8

        mapping_types:
            longblob: object
            blob: object

        # Tips: this allows Doctrine to consider only tables starting with
        # "symfony__" during a migration generation.
        # Think to add Doctrine migrations table here or configure it in
        # the doctrine_migrations section (table_name)
        schema_filter: ~^(symfony__|migration_versions)~

The bundle comes with 3 delivery strategies:

• ekino.drupal.delivery_strategy.background: Drupal never returns the response, Symfony does
• ekino.drupal.delivery_strategy.drupal: Drupal always returns the response, even if the page is 404
• ekino.drupal.delivery_strategy.symfony: Drupal returns the response only if the page is not 404

The (optional) section entity_repositories allows you to easy interact with Drupal API to retrieve contents and handle it from Symfony code. The configuration offers default values:

• default entity type is node
• default repository class is Ekino\Bundle\DrupalBundle\Entity\EntityRepository, feel free to configure yours

Update Queries

UPDATE users SET `emailCanonical` = `mail`, `usernameCanonical` = `name`, `roles` = 'b:0;';

Usage

Symfony components can be used from within Drupal:

<?php
function drupal_foo_function() {
    $result = symfony_service('reusage_service')->foo();

    // do some stuff with $result
}

Security

You can secure a Symfony route with a Drupal permission, with prefix PERMISSION_DRUPAL_. Like it:

security:
    role_hierarchy:
        # ...

    firewalls:
        # ...

    access_control:
        - { path: ^/symfony/admin, role: PERMISSION_DRUPAL_ACCESS_ADMINISTRATION_PAGES }

The PERMISSION_DRUPAL_ACCESS_ADMINISTRATION_PAGES is translate in "access administration pages" and used with user_access and global Drupal user.

If you want use you "personal access" permission, use role PERMISSION_DRUPAL_PERSONAL_ACCESS for example.

Limitations

• It is not possible to use Symfony native class to manage session as Drupal initializes its own session handler and there is no way to change this.
• requests must be served through the index.php as it is the default value in the .htaccess file and there is no way to change the default script in Drupal

Preview

If installation is completed successfully, the welcome page looks like:

You can note the Web Debug Toolbar of Symfony at the bottom ;-).
