Let my application run on localhost, the path is: localhost/silex/web/index.php
, defined routes as in the code below, I'd expect visiting localhost/silex/web/index.php/redirect
redirects me to localhost/silex/web/index.php/foo
and displays 'foo'. Instead it redirects me to localhost/foo
.
I am new to Silex and maybe I got it all wrong. Could someone explain where is the problem? Is it correct behavior and it should redirect for absolute paths? Thanks.
<?php
require_once __DIR__.'/../vendor/autoload.php';
use Symfony\Component\HttpFoundation\Response;
$app = new Silex\Application();
$app['debug'] = true;
$app->get('/foo', function() {
return new Response('foo');
});
$app->get('/redirect', function() use ($app) {
return $app->redirect('/foo');
});
$app->run();
The redirect
url expects an url to redirect to, not an in-app route. Try it this way:
$app->register(new Silex\Provider\UrlGeneratorServiceProvider());
$app->get('/foo', function() {
return new Response('foo');
})->bind("foo"); // this is the route name
$app->get('/redirect', function() use ($app) {
return $app->redirect($app["url_generator"]->generate("foo"));
});
For internal redirects, which does not change the requested URL, you can also use a sub-request:
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\HttpKernelInterface;
$app->get('/redirect', function() use ($app) {
$subRequest = Request::create('/foo');
return $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST, false);
});
See also Making sub-Requests .
Up to "silex/silex": ">= 2.0"
, a native trait allow you to generate an URL based on the route name.
You can replace :
$app['url_generator']->generate('my-route-name');
By :
$app->path('my-route-name');
Then use it to redirect :
$app->redirect($app->path('my-route-name'));
Another possibility is to create a custom trait to directly redirect with a route name :
namespace Acme;
trait RedirectToRouteTrait
{
public function redirectToRoute($routeName, $parameters = [], $status = 302, $headers = [])
{
return $this->redirect($this->path($routeName, $parameters), $status, $headers);
}
}
Add the trait to your application definition :
use Silex\Application as BaseApplication;
class Application extends BaseApplication
{
use Acme\RedirectToRouteTrait;
}
Then use it wherever you need it :
$app->redirectToRoute('my-route-name');
