php - Using Captcha with Symfony2 (2.8) -

i installed captcha bundle using following instruction:

1. add "gregwar/captcha-bundle": "1.0.0" require section in composer.json
2. run windows powershell in root , call php composer.phar update
3. console outputs

warning: php startup: unable load dynamic library 'c:\xampp\php\ext\php_yaml.dll' - nie mo┐na odnalečŠ okreťlonego modu│u. in unknown on line 0 loading composer repositories package information updating dependencies (including require-dev) nothing install or update generating autoload files incenteev\parameterhandler\scripthandler::buildparameters updating "app/config/parameters.yml" file sensio\bundle\distributionbundle\composer\scripthandler::buildbootstrap

4. following instruction can skip step

   // app/autoload.php  $loader->registernamspaces(array(     // ...     'gregwar' => __dir__.'/../vendor/bundles', )); 

but autoload.php files looks following:

use doctrine\common\annotations\annotationregistry; use composer\autoload\classloader;  error_reporting(error_reporting() & ~e_user_deprecated);  $loader = require __dir__.'/../vendor/autoload.php';  annotationregistry::registerloader(array($loader, 'loadclass'));  return $loader; 

5. i enabled bundle:

   // app/appkernel.php  public function registerbundles() {     $bundles = array(         // ...         new gregwar\captchabundle\gregwarcaptchabundle(),     ); } 

6. last instalation step add gregwar_captcha: ~ app/config/config.yml , it's done.

now i'm trying use im controller.

    public function registrationaction(request $request)     {         $user = new models\user();          $form = $this->createformbuilder($user)             ->add('username', 'symfony\component\form\extension\core\type\texttype')             ->add('birth', 'symfony\component\form\extension\core\type\datetype')             ->add('captcha', 'captcha')             ->add('save', 'symfony\component\form\extension\core\type\submittype', array('label' => 'register'))             ->getform();          $form->handlerequest($request);            return $this->render(              'cassyw2bundle:user:registration.html.twig',              array(                 'form' => $form->createview(),             )         );     } 

i error:

compile error: declaration of gregwar\captchabundle\type\captchatype::buildview() must compatible symfony\component\form\formtypeinterface::buildview(symfony\component\form\formview $view, symfony\component\form\forminterface $form, array $options) 

where did wrong?

see doc. version of symfony need version of bundle. try installing without providing version in composer.json.
