Question

我的Zend Form isValid()方法返回false，即使在任何地方都没有显示错误。因为我无法执行isValid()方法并将我的表单值存储到mysql中。我不知道为什么它会在没有错误时返回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");
        $phonenum->setAttribute('class', 'form-control');

        $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);
    }
}

如果您阅读the documentation on the Zend-Framework input-filter class，您可以看到在检查无效后您必须自己从输入过滤器类中获取消息：

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。很可能你会将它们附加到响应对象并以有序的方式将它们返回给客户端。

Zend Form isValid（）返回false
