If you want to mimic this behaviour in Silex, you would need to install the TwigBridge via Composer. Then build the templating
service the same way Symfony does.
This solution works as I have tested it successfully.
<?php
require __DIR__.'/vendor/autoload.php';
use Silex\Application;
use Symfony\Component\Templating\PhpEngine;
use Symfony\Component\Templating\TemplateNameParser;
use Symfony\Component\Templating\Loader\FilesystemLoader;
use Symfony\Component\Templating\DelegatingEngine;
use Symfony\Bridge\Twig\TwigEngine;
$app = new Application();
$app['debug'] = true;
// Register Twig
$app->register(new Silex\Provider\TwigServiceProvider(), array(
'twig.path' => __DIR__.'/views',
));
// Build the templating service
$app['templating.engines'] = $app->share(function() {
return array(
'twig',
'php'
);
});
$app['templating.loader'] = $app->share(function() {
return new FilesystemLoader(__DIR__.'/views/%name%');
});
$app['templating.template_name_parser'] = $app->share(function() {
return new TemplateNameParser();
});
$app['templating.engine.php'] = $app->share(function() use ($app) {
return new PhpEngine($app['templating.template_name_parser'], $app['templating.loader']);
});
$app['templating.engine.twig'] = $app->share(function() use ($app) {
return new TwigEngine($app['twig'], $app['templating.template_name_parser']);
});
$app['templating'] = $app->share(function() use ($app) {
$engines = array();
foreach ($app['templating.engines'] as $i => $engine) {
if (is_string($engine)) {
$engines[$i] = $app[sprintf('templating.engine.%s', $engine)];
}
}
return new DelegatingEngine($engines);
});
// Render controllers
$app->get('/', function () use ($app) {
return $app['templating']->render('hello.html.twig', array('name' => 'Fabien'));
});
$app->get('/hello/{name}', function ($name) use ($app) {
return $app['templating']->render('hello.html.php', array('name' => $name));
});
$app->run();
You would need at least these dependencies to achieve this in your composer.json
"require": {
"silex/silex": "~1.0",
"symfony/twig-bridge": "~2.0",
"symfony/templating": "~2.0",
"twig/twig": "~1.0"
},
