Switch culture from any page of your site and improve SEO


Symfony internationalization is normally managed using session variables. To switch culture you can visit a page that first changes you session variable and then send you back to the page you were visiting, but this potentially breaks your SEO.

Adding culture in every URL is a better solution, but if you want to go back to the page you were visiting, you have to deal with redirection by yourself.

This widget solves the redirection issue by creating localized urls.


Save your file here: apps/appname/lib/helper/I18nUrlHelper.php

 * Generate a localized version for the URL you are visiting.
function localized_current_url($sf_culture = null)
  if (! $sf_culture)
    throw new sfException(sprintf('Invalid parameter $sf_culture "%s".', $sf_culture));
  $routing    = sfContext::getInstance()->getRouting();
  $request    = sfContext::getInstance()->getRequest();
  $controller = sfContext::getInstance()->getController();
  // depending on your routing configuration, you can set $route_name = $routing->getCurrentRouteName()
  $route_name = '';
  $parameters = $controller->convertUrlStringToParameters($routing->getCurrentInternalUri());
  $parameters[1]['sf_culture'] = $sf_culture;
  return $routing->generate($route_name, array_merge($request->getGetParameters(), $parameters[1]));


Obviously, you must add the :sf_culture token in every rule of your application routing.yml:

  url:   /:sf_culture/product/:id
  requirements: { sf_culture: (?:en|es|fr|it|de) }
  param: { module: product, action: show }
  url:   /:sf_culture
  requirements: { sf_culture: (?:en|es|fr|it|de) }
  param: { module: page, action: home }

  url:   /symfony/:sf_culture/:action/*
  requirements: { sf_culture: (?:en|es|fr|it|de) }
  param: { module: default }
  url:   /:sf_culture/:module
  param: { action: index }
  requirements: { sf_culture: (?:en|es|fr|it|de) }
  url:   /:sf_culture/:module/:action/*
  requirements: { sf_culture: (?:en|es|fr|it|de) }

This code let you create a list of link to the localized versions. The list of languages/cultures is taken from your config file.

  <?php foreach(sfConfig::get('app_languages_available') as $language) { ?>
    <a href="<?php echo localized_current_url($language); ?>"><?php echo $language; ?></a>  
  <?php } ?>
