How can I have optional parameters in Symfony2 route?

Question

I have this code below:

/**  * Lists all User entities.  *  * @Route("/{cid}",defaults={"cid" = null},name="user")  * @Template()  */ public function indexAction($cid=null) {} 

Now if I type site/user/1 then it works, but if I type site/user/ it says:

No route found 

How can I have it that both routes work?

Answer 1

Try to go to site/user (notice no backslash at the end).

Generally it should work, I have relatively similar configuration working.

But if all else fails you can always define multiple routes for same action, i.e.

/**  * Lists all User entities.  *  * @Route("/", name="user_no_cid")  * @Route("/{cid}", name="user")  * @Template()  */ public function indexAction($cid=null) { 

Answer 2

Use a yml file for your routing configuration, and add a default value for id in your routing parameters like this:

user:   pattern:   /site/user/{id}   defaults:  { _controller: YourBundle:Default:index, id: 1 }
