Question

这是我尝试查询时的代码片段

   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;

我收到以下错误

无法识别的字段：user_name

您正在查询错误的字段。该字段在您的实体类中名为_username。另外，检查注释，_username和_password似乎没有任何注释，因此不会将它们创建为数据库字段。

如果您正确设置了实体并且所有字段都在数据库中，则只需查询_username属性：

 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;
    }
}

您的用户实体应如下所示：

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 ...
}

您可以查看PSR-2标准。目前不鼓励方法和变量名称中的下划线。

无法识别的字段：user_name，同时使用ZF2查询Via Doctrine
