Drupal Bundle by Ekino

• THIS IS A WORK IN PROGRESS *

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

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 Symdony2.

<?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();

$kernel->handle(Request::createFromGlobals())->send();

Configuration

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

framework:
    # ... configuration options
    session:
        # ... configuration options
        auto_start:     false
        storage_id:     ekino.drupal.session

ekino_drupal:
    root:         %kernel.root_dir%/../web
    strategy_id:  ekino.drupal.delivery_strategy.symfony

The bundle comes with 2 delivery strategies :

• ekino.drupal.delivery_strategy.symfony : Drupal returns the response only if the page is not 404
• ekino.drupal.delivery_strategy.drupal : Drupal always returns the response, event if the page is 404

Usage

Symfony components can be used from within drupal :

<?php
function drupal_foo_function() {
    global $container;

    $result = $container->get('reusage_service')->foo();

    // do some stuff with $result
}

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 server 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
