php - Silex DoctrineORM: Custom Entity Repository -

i have issue when trying build custom entity repository.

"php message: php fatal error:  class 'doctrine\orm\entityrepository' not found in /home/user/projects/app/src/application/database/entityrepository/userrepository.php on line 8 

in customrepository.php file have done this:

<?php     namespace application\database\entityrepository;      use application\bootstrap bootstrap;     use doctrine\orm\entityrepository;      class userrepository extends \doctrine\orm\entityrepository     {          public function getpasswordbyusername($username)         {             $query = $app['orm.em']->createquery('select u.password application\database\entities\users u (u.username = :username)');             $query->setparameter('username', $username);              return $query->getoneornullresult();         }     } 

and in bootstrap file method loaded through constructor in bootstrap class.

use silex\provider\doctrineserviceprovider silexdocprov; use silex\provider\sessionserviceprovider silexsessprov; use dflydev\silex\provider\doctrineorm\doctrineormserviceprovider docprov;  private function initdatabase() {     $this->app->register(new silexdocprovj(), array(         'db.options' => array(             'driver' => 'pdo_mysql',             'host'     => getenv('dbhost'),             'dbname'   => getenv('dbname'),             'user'     => getenv('dbuser'),             'password' => getenv('dbpass')         )     ));      $this->app->register(new docprov(), array(         'orm.em.options' => array(             'mappings' => array(                 array(                     'type' => 'yml',                     'namespace' => 'application\database\entities',                     'path' => __dir__ . '/../../app/config/mappings'                 )             )         )     )); } 

and mappings file has this:

application\database\entities\users:     type: entity     table: users     repositoryclass: \application\database\entityrepository\userrepository 

namespaces case-sensitive.

change

doctrine\orm\entityrepository 

to:

doctrine\orm\entityrepository 

also there's no need full namespace in

extends \doctrine\orm\entityrepository 

because you've imported class

use doctrine\orm\entityrepository; 

so can do:

extends entityrepository
