Symfony 1.4 - route by query string parameters

Question

Is it possible to route request to controllers/actions by query string parameters? And how to do it using routing.yml file?

I mean:

/some/path?do=action1... 


some_route:
    url: /some/path
    param: { module: module1, action: action1 }
    requirements:
        do: action1       <--- ???


/some/path?do=action2

some_route2
   url: /some/path
   param: { module: module1, action: action2 }
   requirements:
        do: action2       <--- ???

or some common route:

some_route:
    url: /some/path?do=:action
    param: { module: module1, action: action }
    requirements:
        do: action\d+       

Thanks!

Answer 1

Yes, it is possible to do so by creating generic rule in routing.yml:

generic_rule:
    url: /some/path/:action
    param: {module: yourmodule}

In this case when you call /some/path/index then indexAction method of yourmodule will be called.

You can even create more generic rule, where both action and module are variables:

more_generic_rule:
    url: /some/path/:module/:action

You can make one action which will check the do parameter and forward you to the proper action, e.g.

main_action:
    url: /some/path/:do
    param: { module: yourmodule, action: mainAction }
    requirements: 
      do: action\d+

Then in the yourmodule/actions/actions.class.php:

public function executeMainAction(sfWebRequest $request)
{
    $do = $request->getParameter('do');

    if (doParameterIsOk($do)) { 
        $this->forward('yourmodule', $do);
    } else {
        // Handle bad `do` parameter.
    }
}
