Zend 表单 isValid() return 假

Question

我的 Zend Form isValid() 方法是 return false，即使在任何地方都没有显示错误。因此，我无法执行 isValid() 方法并将我的表单值存储到 mysql 中。我不知道为什么在没有错误的情况下它会 return 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;
    }

}

我的 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();?>

我的表格：

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");

        $complaintdetail->setLabel("Things to Complaint");
        $complaintdetail->setAttribute('class', 'form-control');

        $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);
    }
}

我的表单验证器：

        $name->setRequired(true);

Answer 1

如果您阅读 the documentation on the Zend-Framework input-filter class，您会发现在检查无效后，您必须自己从输入过滤器 class 获取消息：

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());
    }
}

因此，要查看验证错误消息，您需要获取这些消息并以某种方式自行输出它们。您很可能会将它们附加到响应对象，然后 return 以某种有序的方式将它们附加到客户端。
