How to use Service Container Parameters in your Routes
2.1
The ability to use parameters in your routes was added in Symfony 2.1.
Sometimes you may find it useful to make some parts of your routes globally configurable. For instance, if you build an internationalized site, you'll probably start with one or two locales. Surely you'll add a requirement to your routes to prevent a user from matching a locale other than the locales your support.
You could hardcode your _locale requirement in all your routes. But
a better solution is to use a configurable service container parameter right
inside your routing configuration:
- YAML
- XML
- PHP
1 2 3 4 5
contact:
path: /{_locale}/contact
defaults: { _controller: AcmeDemoBundle:Main:contact }
requirements:
_locale: %acme_demo.locales%You can now control and set the acme_demo.locales parameter somewhere
in your container:
- YAML
- XML
- PHP
1 2 3
# app/config/config.yml
parameters:
acme_demo.locales: en|esYou can also use a parameter to define your route path (or part of your path):
- YAML
- XML
- PHP
1 2 3
some_route:
path: /%acme_demo.route_prefix%/contact
defaults: { _controller: AcmeDemoBundle:Main:contact }Note
Just like in normal service container configuration files, if you actually
need a % in your route, you can escape the percent sign by doubling
it, e.g. /score-50%%, which would resolve to /score-50%.
However, as the % characters included in any URL are automatically encoded,
the resulting URL of this example would be /score-50%25 (%25 is the
result of encoding the % character).
