The DoctrineServiceProvider provides a default Doctrine2 DBAL Connection and an EntityManager.


use Knp\Silex\ServiceProvider\DoctrineServiceProvider;

$app->register(new DoctrineServiceProvider(), array(
    'doctrine.dbal.connection_options' => array(,
        'driver' => 'pdo_sqlite',
        'path' => ':memory'
    'doctrine.orm' => true

// if you want to autoload your entities, use the autoloader service:
$app['autoloader']->registerNamespace('Entity', __DIR__);


  • doctrine.dbal.connection_options: an array of connection parameters for DBAL of the form:
'doctrine.dbal.connection_options' => array(
    'driver' => 'pdo_sqlite',
    'path' => ':memory'


'doctrine.dbal.connection_options' => array(
    'driver' => 'pdo_mysql',
    'dbname' => 'my_database_name',
    'host' => 'localhost',
    'user' => 'root',
    'password' => null

This parameter activates the doctrine.dbal.connection service.

These above are simple examples. Full documentation is available.

  • doctrine.orm (optional): a boolean to activate the doctrine.orm.em service. Defaults to false.
  • doctrine.orm.entities (optional): an array of mapping configurations of the form:
'doctrine.orm.entities' => array(
    array('type' => 'yml', 'path' => '/path/to/yml/files', 'namespace' => 'My\\Entity'),

    array('type' => 'annotation', 'path' => array(
    ), 'namespace' => 'Entity'),

    array('type' => 'annotation', 'path' => '/path/to/another/dir/with/entities', 'namespace' => 'Acme\\Entity'),

    array('type' => 'xml', 'path' => '/path/to/xml/files', 'namespace' => 'Your\\Entity')

This is an advanced configuration example which replaces the default one:

array('type' => 'annotation', 'path' => 'Entity', 'namespace' => 'Entity')

Default behavior will search annotated Entities in the Entity directory.

  • doctrine.orm.proxies_dir (optional): Path to where the doctrine Proxies are generated. Default is cache/doctrine/Proxy.
  • doctrine.orm.proxies_namespace (optional): Namespace of generated doctrine Proxies. Default is DoctrineProxy.
  • doctrine.orm.auto_generate_proxies (optional): Tell Doctrine wether it should generate proxies automatically. Default is true.
  • doctrine.orm.class_path (optional): Path to where the Doctrine\ORM library is located.
  • doctrine.common.class_path (optional): Path to where the Doctrine\Common library is located.
  • doctrine.dbal.class_path (optional): Path to where the Doctrine\DBAL library is located.


  • doctrine.dbal.connection: The Doctrine\DBAL\Connection instance.
  • doctrine.dbal.event_manager: The Doctrine\DBAL\EventManager instance.
  • doctrine.configuration: The Doctrine\ORM\Configuration instance or Doctrine\DBAL\Configuration if doctrine.orm is false.
  • doctrine.orm.em: The Doctrine\ORM\EntityManager instance.


  • DBAL
$categories = $app['doctrine.dbal.connection']->query('SELECT * FROM category')->fetchAll();
  • ORM
$category = $app['doctrine.orm.em']->getRepository('Acme\Entity\Category')->findOneBy(array('name' => 'Category A'));
  • Event subscribers, Behaviors

This is an example of how to add a Timestampable behavior to Doctrine. ( )

// if you need autoloading of external lib
$app['autoloader']->registerNamespace('Gedmo', __DIR__.'/vendor/Gedmo/DoctrineExtensions/lib');

$timestampableListener = new \Gedmo\Timestampable\TimestampableListener();
