Variable on a prefix on symfony2 routing

Question

I need a variable on a prefix on my symfony2 routing so that i can do something like this in the main routing file:

//app/config/routing.yml
god:
    resource: "@Acme/DemoBundle/Resources/config/routing.yml"
    prefix: /god/{religion}

and then something like this in the bundle routing file:

gods_route_to_heaven:
    path: /path_to_heaven
    defaults: { _controller: AcmeBlogBundle:God:show }

so that i can access paths like this:

/god/Christianity/path_to_heaven
/god/Islam/path_to_heaven
/god/Hinduism/path_to_heaven

and so on.

If i type app/console route:debug | grep api on the console i get the correct route /god/{religion}/path_to_heaven, so the route is being generated correctly.

But when I try to get the parameter in the controller by placing it as an input in the action function like this:

public function showAction($religion)

the path gets corrupted and dumping the paths i see it gets duplicated: /god/{religion}/path_to_heaven/{religion}

So how would i get the $religion variable from inside the controller?

Answer 1

You can get the religion value like this:

use Symfony\Component\HttpFoundation\Request;

...

public function showAction(Request $request){
   $yourReligionIs = $request->get('religion');
}

I'm facing the same problème with Symfony and FOSUserBundle.
In FOSUserBundle the profile link are :

site_url/profile/
site_url/profile/edit
site_url/profile/change-password

I have an admin and dashboard panel, and I want the links to be in admin panel

site_url/admin/profile/
site_url/admin/profile/edit
site_url/admin/profile/change-password

and in the user dashboard

site_url/dashboard/profile/
site_url/dashboard/profile/edit
site_url/dashboard/profile/change-password

To get this behavior it's very simple without EventListener and TwigExtesion
Here the solution:

replace

fos_user:
    resource: "@FOSUserBundle/Resources/config/routing/all.xml"

by

fos_user_security:
    resource: "@FOSUserBundle/Resources/config/routing/security.xml"
fos_user_registration:
    resource: "@FOSUserBundle/Resources/config/routing/registration.xml"
fos_user_resetting:
    resource: "@FOSUserBundle/Resources/config/routing/resetting.xml"
fos_user_change_password:
    resource: "@FOSUserBundle/Resources/config/routing/change_password.xml"
    prefix:   /{prefix}/profile 
fos_user_profile:
    resource: "@FOSUserBundle/Resources/config/routing/profile.xml"
    prefix:   /{prefix}/profile

In a template use:

<a href="{{ path('fos_user_profile_show', {'prefix': 'dashboard'}) }}">Show Profile</a>
<a href="{{ path('fos_user_profile_edit', {'prefix': 'dashboard'}) }}">Edit Profile</a>
<a href="{{ path('fos_user_change_password', {'prefix': 'dashboard'}) }}">Change Password</a>

Or any other prefix you want
Now if you use for example the change password link you will get this error

An exception has been thrown during the rendering of a template ("Some mandatory parameters are missing ("prefix") to generate a URL for route "fos_user_change_password".") in FOSUserBundle:ChangePassword:changePassword_content.html.twig at line 3.

you can add the prefix in the template like so:
replace

<form action="{{ path('fos_user_change_password') }}" {{ form_enctype(form) }} method="POST" class="fos_user_change_password"> 

by

<form action="{{ path('fos_user_change_password', {'prefix': app.request.attributes.get('prefix') }) }}" {{ form_enctype(form) }} method="POST" class="fos_user_change_password">

this will give you this error

Some mandatory parameters are missing ("prefix") to generate a URL for route "fos_user_profile_show".

the final solution that I found is to override the controller
just copy the hole controle in your app controller folder,change the namesapce and replace

if (null === $response = $event->getResponse()) {
                $url = $this->generateUrl('fos_user_profile_show');
                $response = new RedirectResponse($url);
            }

by

if (null === $response = $event->getResponse()) {
                $url = $this->generateUrl('fos_user_profile_show',array('prefix'=>$request->get('prefix')));
                $response = new RedirectResponse($url);
            }

in the form you don't need the action so it will be

<form  {{ form_enctype(form) }} method="POST" class="fos_user_change_password">

You may solve this problem in this way-

god:
    resource: "@Acme/DemoBundle/Resources/config/routing.yml"
    prefix: /god/{_locale}/

no need to change in here--

gods_route_to_heaven:
    path: /path_to_heaven
    defaults: { _controller: AcmeBlogBundle:God:show }

modification in here--

    public function showAction(){
       // below line is extra if you need
         $post   = $this->get('request')->request->all();
         $religion = $post['religion']; 
    }

I didn't test this code but all process is well proved. If you will see any problem let discuss.

Answer 4

the possible solution you need, would be:

File: src/Acme/CoreBundle/Twig/PathExtension.php

<?php

namespace Acme\CoreBundle\Twig\Extension;

use Symfony\Bundle\FrameworkBundle\Routing\Router;
use Symfony\Component\HttpKernel\Event\GetResponseEvent;
use Symfony\Component\HttpKernel\HttpKernel;

class PathExtension extends \Twig_Extension
{

    private $request;
    private $router;

    public function __construct(Router $router) {
        $this->router = $router;
    }

    public function onKernelRequest(GetResponseEvent $event) {
        if ($event->getRequestType() === HttpKernel::MASTER_REQUEST) {
            $this->request = $event->getRequest();
        }
    }

    public function getFunctions()
    {
        return array(
            'path_route' => new \Twig_Function_Method($this, 'getPath')
        );
    }

    public function getPath($name, $parameters = array())
    {
        $parameters = array_merge($parameters, [
            'religion' => $this->request->get('religion'),
        ]);

        return $this->router->generate($name, $parameters, false);
    }

    public function getName()
    {
        return 'twig_path_route_extension';
    }

}

Configuration as service:

File: src/Acme/CoreBundle/Resources/config/services.yml

services:
    twig.path_route_extension:
        class: Acme\CoreBundle\Twig\PathExtension
        tags:
            - { name: twig.extension }
            - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }
        arguments: [@router]

Set your routing options:

File: app/config/routing.yml

_acme_religion:
    resource: "@AcmeCoreBundle/Resources/config/routing.yml"
    prefix:   /god/{religion}/

Then you can use it in the templates and the routing.yml, for ex:

_religion_pathheaven:
    path:     /path_to_heaven
    defaults: { _controller: AcmeCoreBundle:System:getpathheaven }

Then, in your templates, you can use:

<a href="{{ path_route('_religion_pathheaven') }}">
  Link Path to heaven.
</a>

Answer 5

Have you tried this?

//app/config/routing.yml
god:
    resource: "@Acme/DemoBundle/Resources/config/routing.yml"
    prefix: /god

and then something like this in the bundle routing file:

gods_route_to_heaven:
    path: /{religion}/path_to_heaven
    defaults: { _controller: AcmeBlogBundle:God:show }

Let me know if it works.
