在zend框架2中创建登录表单

I am trying to create login page in zend framework2. I have created its view,controller,model and form. Even i m not getting any error.

following my code :

My model as Login.php is :

class Login implements InputFilterAwareInterface
 {
     public $id;
     public $username; 
     public $password;
      protected $inputFilter;

     public function exchangeArray($data)
     {
         $this->id     = (!empty($data['id'])) ? $data['id'] : null;
         $this->username = (!empty($data['username'])) ? $data['username'] : null;
         $this->password  = (!empty($data['password'])) ? $data['password'] : null;
     }
      public function getArrayCopy()
     {
         return get_object_vars($this);
     }

      public function setInputFilter(InputFilterInterface $inputFilter)
     {
         throw new \Exception("Not used");
     }

     public function getInputFilter()
     {
         if (!$this->inputFilter) {
             $inputFilter = new InputFilter();

             $inputFilter->add(array(
                 'name'     => 'id',
                 'required' => true,
                 'filters'  => array(
                     array('name' => 'Int'),
                 ),
             ));

             $inputFilter->add(array(
                 'name'     => 'username',
                 'required' => true,
                 'filters'  => array(
                     array('name' => 'StripTags'),
                     array('name' => 'StringTrim'),
                 ),
                 'validators' => array(
                     array(
                         'name'    => 'StringLength',
                         'options' => array(
                             'encoding' => 'UTF-8',
                             'min'      => 1,
                             'max'      => 100,
                         ),
                     ),
                 ),
             ));

             $inputFilter->add(array(
                 'name'     => 'password',
                 'required' => true,
                 'filters'  => array(
                     array('name' => 'StripTags'),
                     array('name' => 'StringTrim'),
                 ),
                 'validators' => array(
                     array(
                         'name'    => 'StringLength',
                         'options' => array(
                             'encoding' => 'UTF-8',
                             'min'      => 1,
                             'max'      => 100,
                         ),
                     ),
                 ),
             ));

             $this->inputFilter = $inputFilter;
         }

         return $this->inputFilter;
     }
 }

My LoginForm is :

namespace Application\Form;

 use Zend\Form\Form;

 class LoginForm extends Form
 {
     public function __construct($name = null)
     {
         // we want to ignore the name passed
         parent::__construct('tbluser');

         $this->add(array(
             'name' => 'id',
             'type' => 'Hidden',
         ));
         $this->add(array(
             'name' => 'username',
             'type' => 'Text',
             'options' => array(
                 'label' => '',

             ),
             'attributes' => array(
                 'id' => 'username',
                 'class'=>'',
                 'autocomplete'=>'OFF',
                 'max'=>'100',
             ),
         ));
         $this->add(array(
             'name' => 'password',
             'type' => 'Text',
             'options' => array(
                 'label' => '',
             ),
             'attributes' => array(
                 'id' => 'password',
                 'class'=>'',
                 'autocomplete'=>'OFF',
                 'max'=>'100',
             ),
         ));
         $this->add(array(
             'name' => 'submit',
             'type' => 'Submit',
             'attributes' => array(
                 'value' => 'Login',
                 'id' => 'login',
                 'class'=>'btn btn-success',
             ),
         ));


     }
 }

and my controller action code is :

public function indexAction() 
    {

    $form = new LoginForm();
    $request = $this->getRequest();
    $user=new LoginTable();
           if ($request->isPost()) {
             $login = new Login();
             $form->setInputFilter($login->getInputFilter());
             $form->setData($request->getPost());
              if ($form->isValid()) {
                 $data=$login->exchangeArray($form->getData());
                 $user->getUser($this->$username,$this->$password);
                  if($user){    
                    return $this->redirect()->toRoute('album', array(
                 'action' => 'album'));
                    }else{
                    return array('form' => $form);
                    }              
             }

         }

         return array('form' => $form);




    }

my form is not validating at this statement "if ($form->isValid()){}" the exicution is not entering in this statement. I searched out every thing but not able to find solution what i m missing. Can any body help me to get out of this.

    Looking at the form it looks as if you have an input filter attached to the hidden field id. If you are looking to register the user you obviously will not have their id before authentication.

    You can test this by adding a else statement of your form and checking the forms messages (because the element is hidden you will not see it output otherwise)

    if ($form->isValid()) {
       // Is valid code here
    } else {
       print_r($form->getMessages());
    }
    

    This will probably output and array with the message "id - this element cannot be empty" or something similar.

    The solution would be to remove the id input filter from the form (and probably the id form element as I can't see how this would be needed).
