What is it?

IngewikkeldWrapperBundle is a simple Symfony2 bundle to wrap your old legacy symfony 1 application. This allows you to gradually refactor your old symfony 1 code with spankin' new Symfony2 code.

IngewikkeldWrapperBundle works with a fallback route. All routes that are not caught by your Symfony2 code are routed into the IngewikkeldWrapperBundle, which in turn bootstraps your symfony 1 project.

Note: While this bundle can be very useful, it is not recommended to use it for too long. You are running two different frameworks for each request that goes through this bundle, meaning there's two frameworks adding an overhead to each request. If you have the possibility, look into caching the output of your legacy code in Symfony2.


Installation is done in just a couple of steps:

  1. Using composer
  2. Download the bundle
  3. Configure the autoloader
  4. Enable the bundle
  5. Configure your legacy project
  6. Copy your assets to the document root
  7. Configure your routing
  8. Refactor your project

1. Using composer

Require the bundle

$ composer require Ingewikkeld/WrapperBundle:dev-master

2. Download the bundle (if not using composer)

Make sure the bundle is being placed in vendor/bundles/Ingewikkeld/IngewikkeldWrapperBundle. You can do this by using the vendors script, using submodules or downloading the zip file.

vendors script

Open the deps file in your Symfony2 project, and add the following:


Now, install the vendors by running:

$ bin/vendors install


If you are using Git, you can also use submodules to install the bundle into your project. Execute the following commands in your project root:

$ git submodule add git:// vendor/bundles/Ingewikkeld/WrapperBundle
$ git submodule update --init

zip file

Of course, you can just download the zip file from Github. Unzip the file and copy the contents of the zip-file into the vendor/bundles/Ingewikkeld/WrapperBundle directory of your Symfony2 project.

3. Configure the autoloader (if not using composer)

Before the Ingewikkeld namespace can be loaded, we need to set up the autoloader to actually load the namespace. For this to work, you need to edit the app/autoload.php file. In the $loader->registerNamespaces() call, you need to add the Ingewikkeld namespace, like this:

    // ...
    'Ingewikkeld'      => __DIR__.'/../vendor/bundles',

4. Enable the bundle

Enable the bundle in the AppKernel (app/AppKernel.php). In the registerBundles() method, add the WrapperBundle to the $bundles array:

   $bundles = array(
        // ...
        new Ingewikkeld\WrapperBundle\IngewikkeldWrapperBundle(),

5. Configure your legacy project

Put your legacy project in your app/ directory. For my first project, I put my whole project into the app/legacy/ directory. Now, add some configuration values to app/config/config.yml to set up the WrapperBundle to serve pages from your legacy symfony 1 project:

    wrapper_legacypath: legacy # directory inside app/ where your project is located
    wrapper_app: frontend # app to load
    wrapper_env: prod # environment to load
    wrapper_debug: false # whether debug is on or not
    wrapper_version: 1.4 # Symfony version of the legacy project you are wrapping in this bundle 

6. Copy your assets to the document root

All files that need to be available in the document root need to be copied there from your legacy project. Right now, those are not yet automatically loaded (see "Known issues"), so they have to be copied over to the web/ directory of your Symfony2 project. Usually, you copy over the images/, css/, js/ and uploads/ directories.

7. Configure your routing

At the bottom of your app/config/routing.yml file, add the following:

IngewikkeldWrapperBundle: resource: "@IngewikkeldWrapperBundle/Controller/" type: annotation prefix: /

This will ensure the wrapper route will catch all requests that are not caught by any other route.

8. Refactor your project

Now, start refactoring and porting your legacy project into Symfony2 code.

Current state of the project

The current state of the project is: Proof of Concept

It is working for me right now for one of my legacy projects using this approach. This is with a symfony 1.0 project. It might not (yet) work for you. I greatly welcome pull requests to add features or ensure compatibility with other versions of symfony 1. If you've confirmed this bundle to work with another version of symfony 1, please also let me know!

Known issues / TODO

  1. Assets are not automatically loaded but have to be copied over to the Symfony2 documentroot
  2. Compatibility is so far only confirmed with symfony 1.0
  3. It is currently only possible to load one symfony 1-app
  4. No session sharing at the moment


  1. Symfony 1.4 support is confirmed but with Swiftmailer conflicts. Either remove the Swiftmailer line from composer.json and update deps (easier method) or remove the legacy version.
