How to Include External Routing Resources

Warning: You are browsing the documentation for Symfony 2.x, which is no longer maintained.

Read the updated version of this page for Symfony 7.1 (the current stable version).

Simple applications can define all their routes in a single configuration file - usually app/config/routing.yml (see Routing). However, in most applications it's common to import routes definitions from different resources: PHP annotations in controller files, YAML or XML files stored in some directory, etc.

This can be done by importing routing resources from the main routing file:

# app/config/routing.yml
app_file:
    # loads routes from the given routing file stored in some bundle
    resource: '@AcmeOtherBundle/Resources/config/routing.yml'

app_annotations:
    # loads routes from the PHP annotations of the controllers found in that directory
    resource: '@AppBundle/Controller/'
    type:     annotation

app_directory:
    # loads routes from the YAML or XML files found in that directory
    resource: '../legacy/routing/'
    type:     directory

app_bundle:
    # loads routes from the YAML or XML files found in some bundle directory
    resource: '@AppBundle/Resources/config/routing/public/'
    type:     directory

Note

When importing resources from YAML, the key (e.g. app_file) is meaningless. Just be sure that it's unique so no other lines override it.

Prefixing the URLs of Imported Routes

You can also choose to provide a "prefix" for the imported routes. For example, suppose you want to prefix all routes in the AppBundle with /site (e.g. /site/blog/{slug} instead of /blog/{slug}):

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;

/**
 * @Route("/site")
 */
class DefaultController
{
    // ...
}

The path of each route being loaded from the new routing resource will now be prefixed with the string /site.

Adding a Host Requirement to Imported Routes

You can set the host regex on imported routes. For more information, see How to Match a Route Based on the Host.
