How to Include External Routing Resources

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:

  • YAML
  • XML
  • PHP

# 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}):

  • Annotations
  • YAML
  • XML
  • PHP

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.
