How it works

The aim of the bundle is to allow a legacy project to handle HTTP requests instead of Symfony 2, in a simple way:

• let Symfony try to find a controller that matches the request
• if it can't, it let the legacy project try to return a response
• otherwise return a 404 response

To do so, the LegacyWrapperBundle provides a `RouterLister` which will delegates the request handling to the `RouterListener` of Symfony 2 and if a `HttpNotFoundException` is thrown it will call the legacy kernel, which is an implementation of the HttpKernelInterface of the legacy project.

Installation

This bundle requires Symfony 2.4 or higher.

Add the following lines to your composer.json:

"require": {
    ...
    "composer/composer": "~1.0@dev",
    "theodo-evolution/legacy-wrapper-bundle": "~1.0"
    ...
},

And run Composer:

php composer.phar update theodo-evolution/legacy-wrapper-bundle

Configuration

Add the bundles in your app/AppKernel.php:

public function registerBundles()
{
    $bundles = array(
        //vendors, other bundles...
        new Theodo\Evolution\Bundle\LegacyWrapperBundle\TheodoEvolutionLegacyWrapperBundle(),
    );
}

Configure the bundle in your app/config/config.yml:

• Symfony >=1.4 configuration
• Code Igniter ~2.1 configuration
• Custom kernel configuration

Autoloading

To make the legacy application handle the request or to use the legacy code from Symfony 2 (in a controller for example) you must autoload it.

See the autoloading guide.
