  • EkinoDrupalBundle was initially developed not for Symfony 4.
  • This customized version is fixed for Symfony 4.4 and Symfony will handle Drupal session.
  • The original version will let Drupal bootstrap first and then symfony. This version make Symfony first.
  • Symfony will handle Drupal authentication
  • We can use both Symfony Routing or Drupal menu for page handling.

The bundle deeply integrates Bricks by 20steps including Symfony 4 with Drupal7 and vice versa. This is done with small modification to Drupal core.


  • Require this bundle.
  • Enable bundle.
  • Copy ToSymfony.patch to project root folder and apply it
  • Copy files Resources/ekino_drupal.yaml to config folder.
  • Merge settings in Resources/security.yaml into the config/security.yaml
  • Copy settings in Resources/ekino_drupal_routes.yaml into the end of config/routes.yaml
  • Run MySQL Table Creation for sessions and rememberMe token.
  • Tweak config/security.yaml for firewall control.

CREATE TABLE sessions_sym ( sess_id VARCHAR(128) NOT NULL PRIMARY KEY, sess_data BLOB NOT NULL, sess_time INTEGER UNSIGNED NOT NULL, sess_lifetime INTEGER UNSIGNED NOT NULL ) COLLATE utf8mb4_bin, ENGINE = InnoDB;

CREATE TABLE rememberme_token ( series char(88) UNIQUE PRIMARY KEY NOT NULL, value char(88) NOT NULL, lastUsed datetime NOT NULL, class varchar(100) NOT NULL, username varchar(200) NOT NULL );

Below is original Configuration from Ekino

Adapt the etc/config/ekino_drupal.yaml file to your needs:

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

    # ... configuration options
        # ... configuration options

    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
        # 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
        enabled: false
        prefix:  symfony__
        exclude: [users]

    # optional
        refresh_cookie_lifetime: true # default value: false

# declare 2 required mapping definition used by Drupal
        driver:   %database_driver%

        # 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 7.x 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;';


Symfony services can be used from within Drupal:

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

    // do some stuff with $result


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

        # ...

        # ...

        - { 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.


  • 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.

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