Question

我正在创建注册表单：

这是我的行动：

public function registrationAction() {
    $form = new RegistrationForm();

    $request = $this->getRequest();
    if ($request->isPost()) {
        $users = new Users();
        $form->setInputFilter($users->getInputFilter());
        $form->setData($request->getPost());

        var_dump($form->isValid());
        exit;

        if ($form->isValid()) {
            $users->exchangeArray($form->getData());
            $this->getUsersTable()->addUser($users);
            $message = 'Регистрирахте се успешно! Можете да влезете в профила си чрез формата за вход на началната страница.';
        }
    }

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

这是我的表格：

namespace Main\Form;

use Zend\Form\Form;

class RegistrationForm extends Form {

public function __construct($name = null) {
    parent::__construct('User');

    $this->add(array(
        'name' => 'username',
        'attributes' => array(
            'type' => 'Zend\Form\Element\Text',
        ),
        'options' => array(
            'label' => 'Потребителско име',
        ),
    ));

    $this->add(array(
        'name' => 'email',
        'attributes' => array(
            'type' => 'Zend\Form\Element\Text',
        ),
        'options' => array(
            'label' => 'Email адрес',
        ),
    ));

    $this->add(array(
        'name' => 'password',
        'attributes' => array(
            'type' => 'Zend\Form\Element\Text',
        ),
        'options' => array(
            'label' => 'Парола',
        ),
    ));

    $this->add(array(
        'name' => 'submit',
        'attributes' => array(
            'type' => 'Zend\Form\Element\Submit',
        ),
        'options' => array(
            'label' => 'Регистрация',
        )
    ));
}

}

以下是Object \ Model \ Users.php中的Users模型中的inputFilter：

    $this->user_id = (isset($data['user_id'])) ? $data['user_id'] : null;

当我尝试访问$ form对象的isValid（）或getMessages（）方法时，它们是空的。在var_dump中调用它们时，它们总是布尔为假...有人可以帮助我吗？提前致谢。这只发生在这个模块中。在我的其他模块中，表格中的一切都没问题。这个ZF2有时很复杂......：|

Answer 1

我遇到了和你一样的问题，isValid（）会返回false，而getMessages（）则是一个空数组。

我的问题是我已经为字段（例如电子邮件）定义了输入验证器，但该字段在我验证的表单上不存在。在这种情况下，Zend Framework 2中似乎有一个错误不会打印错误消息：bug report on github

因此，解决方案是将缺少的字段添加到表单对象。

Answer 2

检查字段名称的拼写是否与输入过滤器中的名称相符 - 我做了同样的事情。

Answer 3

我遇到了同样的问题，因为表单和过滤器没有相同数量的属性。

您的注册表单的属性比您的过滤器少。

Answer 4

你写的（在控制器中）是正常的吗？

var_dump($form->isValid());
exit;

如果发生错误，可能只是显示“消息”，不是吗？

Answer 5

我找不到错误，但这里有一些提示：

您不需要使用InputFactory将元素设置为InputFilter，ZF2会自动执行（ZF2 Docs）

最后，默认的InputFilter实现由Factory支持。这意味着在调用add（）时，您可以提供Factory将理解的规范，并且它将创建适当的对象。您可以以这种方式创建Input或InputFilter对象。

所以而不是

$inputFilter->add($factory->createInput(array(
                'name' => 'user_id',
                'filters' => array(
                    array('name' => 'Int'),
                ),
            )));

你可以做到

$inputFilter->add(array(
    'name' => 'user_id',
         'filters' => array(
             array('name' => 'Int'),
          ),
     ));

另一件事，如果你为同一个实例调用$ form-＆gt; isValid（）两次，第二个会导致一些不可见的错误，其余的代码将不会被执行。我不知道发生了什么错误，但你可以为每个$ form实例调用一次isValid。
