Zend表單isValid（）返回false

Question

我的Zend表單isValid()方法返回false，即使在任何地方都沒有錯誤顯示。因此，我不能執行isValid()方法並將我的表單值存儲到mysql中。我不知道爲什麼它會在沒有錯誤時返回false。

我的控制器：

class IndexController extends AbstractActionController 
{ 
    private $usersTable; 

    public function indexAction() 
    { 
     return new ViewModel(); 
    } 

    public function addAction() 
    { 
     $form = new Add(); 

     if($this->request->isPost()) 
     { 
      $complaintPost = new Post(); 
      $form->bind($complaintPost); 
      $form->setInputFilter(new AddPost()); 
      $form->setData($this->request->getPost()); 
      $a = 'apple'; 
      $b = 'boy'; 
      if($form->isValid()) // Check whether it is running or not 
      { 
       echo "<script>console.log($a);</script>"; 
       $complaintPost = $form->getData(); 
       //"<script>console.log($this->getUsersTable()->insert($data));</script>"; 
       $this->getUsersTable()->insert($complaintPost); //checking whether is it null 
      } 
      else 
      { 
       echo "<script>console.log($form->isValid());</script>"; 
      } 
     } 

     return new ViewModel(array(
       'form' => $form, 
       )); 
    } 

    public function getUsersTable() 
    { 
     if(!$this->usersTable) 
     { 
      $this->usersTable = new TableGateway(
        'complaint', 
       $this->getServiceLocator()->get('Zend\Db\Adapter\Adapter') 
      ); 
     } 
     return $this->usersTable; 
    } 

} 

我PHTML文件：

<h1>Add Complaint</h1> 

<?php 
/** @var \Zend\Form\Form $form */ 
    $form = $this->form; 
    $form->prepare(); 
    echo $this->form()->openTag($form); 
?> 

<div class="form-group"> 
    <?php echo $this->formRow($form->get('name'));?> 
</div> 
<div class="form-group"> 
    <?php echo $this->formRow($form->get('icno'));?> 
</div> 
<div class="form-group"> 
    <?php echo $this->formRow($form->get('address'));?> 
</div> 
<div class="form-group"> 
    <?php echo $this->formRow($form->get('phoneno'));?> 
</div> 
<div class="form-group"> 
    <?php echo $this->formRow($form->get('complaintdetail'));?> 
</div> 
<div class="form-group"> 
    <?php echo $this->formRow($form->get('datetime'));?> 
</div> 
<div class="form-group"> 
    <?php echo $this->formRow($form->get('image'));?> 
</div> 
<div class="form-group"> 
    <?php echo $this->formRow($form->get('location'));?> 
</div> 
<div class="form-group"> 
    <?php echo $this->formRow($form->get('remarks'));?> 
</div> 

<?php echo $this->formSubmit($form->get('submit'));?> 
<?php echo $this->form()->closeTag();?> 

我的形式：

class Add extends Form 
{ 
    public function __construct() 
    { 
     parent::__construct('add'); 
     $this->setHydrator(new ClassMethods()); 

     //More to add 
     $name = new Element\Text('name'); 
     $name->setLabel("Name"); 
     $name->setAttribute('class', 'form-control'); 

     $nric = new Element\Text('icno'); 
     $nric->setLabel("NRIC"); 
     $nric->setAttribute('class', 'form-control'); 

     $address = new Element\Text('address'); 
     $address->setLabel("Address"); 
     $address->setAttribute('class', 'form-control'); 

     $phonenum = new Element\Text('phoneno'); 
     $phonenum->setLabel("Phone Number"); 
     $phonenum->setAttribute('class', 'form-control'); 

     $complaintdetail = new Element\Text('complaintdetail'); 
     $complaintdetail->setLabel("Things to Complaint"); 
     $complaintdetail->setAttribute('class', 'form-control'); 

     $dateHappen = new Element\Text('datetime'); 
     $dateHappen->setLabel("Date and time"); 
     $dateHappen->setAttribute('class', 'form-control'); 

     $picture = new Element\File('image'); 
     $picture->setLabel('Photo'); 
     $picture->setAttribute('id', 'image'); 

     $location = new Element\Text('location'); 
     $location->setLabel("Location"); 
     $location->setAttribute('class', 'form-control'); 

     $remarks = new Element\Text('remarks'); 
     $remarks->setLabel("Remarks"); 
     $remarks->setAttribute('class', 'form-control'); 

     $submit = new Element\Submit('submit'); 
     $submit->setValue('Sent Complaint'); 
     $submit->setAttribute('class', 'btn btn-primary'); 

     $this->add($name); 
     $this->add($nric); 
     $this->add($address); 
     $this->add($phonenum); 
     $this->add($complaintdetail); 
     $this->add($dateHappen); 
     $this->add($picture); 
     $this->add($location); 
     $this->add($remarks); 
     $this->add($submit); 
    } 
}

Answer 1

如果你讀the documentation on the Zend-Framework input-filter class，你可以看到你有檢查無效後拿到自己從輸入濾波級的消息：

if ($inputFilter->isValid()) { 
    echo "The form is valid\n"; 
} else { 
    echo "The form is not valid\n"; 
    foreach ($inputFilter->getInvalidInput() as $error) { 
     print_r($error->getMessages()); 
    } 
} 

所以就看你需要得到這些信息，並將其輸出的驗證錯誤信息你自己在某種程度上。很有可能你會把它們附加到一個響應對象上，然後以一種有序的方式將它們返回給客戶端。
