Symfony http to https

Secure SSL(https) Redirect Filter for Symfony

please follow the steps given below to put up specific page to https or secure url:

1) First add the following settings to your app.yml file:

all:
  ssl:
    insecure_host:    www.avidindiainc.com/blog
    secure_host:      www.avidindiainc.com    
    secure_actions:
      - { module: shop, action: register }
      - { module: shop, action: checkout }
      - { module: register, action: updateCardDetails }

2) Next we add our filter code to lib/sslFilter.class.php (apps/[application name]/lib):

/**
 * Filter for redirecting to SSL for the pages that need it
 *
 * @author Sachin Makwana <sachin@avidindiainc.com>
 * @version 2
 */
class sslFilter extends sfFilter
{
  /**
   * Execute filter
   *
   * @param FilterChain $filterChain The symfony filter chain
   */
  public function execute ($filterChain)
  {
    // Only execute this filter once
    if ($this->isFirstCall() && SF_ENVIRONMENT != 'dev') {
      // Array of modules/actions that require move to SSL
      $ssl_actions = sfConfig::get('app_ssl_secure_actions');

      if (empty($_SERVER['HTTPS']) && count($_POST) < 1) {

        // We're not using SSL and not POSTing data - check if we should be using SSL
        foreach ($ssl_actions as $action) {
          if ($this->getContext()->getModuleName() == $action['module'] && $this->getContext()->getActionName() == $action['action']) {
            $new_url = sprintf('https://%s%s', sfConfig::get('app_ssl_secure_host'), $_SERVER['REQUEST_URI']);
            header('Location: ' . $new_url);
            exit;
          }
        }

        // Using secure host when not required - not good
        if ($_SERVER['HTTP_HOST'] == sfConfig::get('app_ssl_secure_host')) {
          $new_url = sprintf('http://%s%s', sfConfig::get('app_ssl_insecure_host'), $_SERVER['REQUEST_URI']);
          header('Location: ' . $new_url);
          exit;
        }
      } elseif (!empty($_SERVER['HTTPS']) && count($_POST) < 1) {

        // We're using SSL and not posting data
        $dont_redirect = false;
        foreach ($ssl_actions as $action) {
          if ($this->getContext()->getModuleName() == $action['module'] && $this->getContext()->getActionName() == $action['action']) {
            $dont_redirect = true;
          }
        }
        if ($dont_redirect == false) {
          // Redirect
          $new_url = sprintf('http://%s%s', sfConfig::get('app_ssl_insecure_host'), $_SERVER['REQUEST_URI']);
          header('Location: ' . $new_url);
          exit;
        }
      }
    }
    // Next filter
    $filterChain->execute();
  }
}

3) Finally, enable your sslFilter in the application’s config/filters.yml configuration file:

sslFilter:
  class:  sslFilter
