無法識別的領域：USER_NAME，而使用ZF2

Question

這裏查詢通過主義是摘錄到我的代碼時，我嘗試查詢像這樣

if ($request->isPost()) { 
     $form->setData($request->getPost()); 
     if ($form->isValid()) { 

      //check authentication... 
      $this->getAuthService()->getAdapter() 
        ->setIdentity($request->getPost('username')) 
        ->setCredential($request->getPost('password')); 

      $username = $request->getPost('username'); 
      $password = $request->getPost('password'); 
      $result = $this->getAuthService()->authenticate(); 

      $criteria = array("user_name" => $username,); 
      $results= $this->getEntityManager()->getRepository('Subject\Entity\User')->findBy($criteria); 
      print_r($results); 
      exit; 

我得到以下錯誤

無法識別的領域： USER_NAME

這些都是我的包括

Answer 1

您要查詢的錯誤的領域。該字段在您的實體類中被命名爲_username。另外檢查你的註釋，_username和_password似乎沒有任何，所以他們不會被創建爲數據庫字段。

如果您設置實體正確，所有字段在數據庫中，你只需要查詢您的_username屬性：

if ($request->isPost()) { 
    $form->setData($request->getPost()); 
    $repo = $this->getEntityManager()->getRepository('Subject\Entity\User'); 
    if ($form->isValid()) { 
     // snip ... 
     $criteria = array("_username" => $username,); 
     $results= $repo->findBy($criteria); 
     print_r($results); 
     exit; 
    } 
} 

您的用戶實體應該是這個樣子：

class User implements InputFilterAwareInterface { 
    /** 
    * @ORM\Column(name="username", type="string", length=64, unique=true) 
    */ 
    protected $_username; 
    /** 
    * @ORM\Column(name="password", type="string", length=64) 
    */ 
    protected $_password; 

    // snip ... 
} 

你可能會查看PSR-2標準。方法和變量名中的下劃線現在不鼓勵。
