php - Zend Framework 2 : Empty isValid/getMessages

我正在创建注册表:

这是我的 Action :

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',
        )
    ));
}

}

这是Object\Model\Users.php中Users模型中的inputFilter:

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

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

    $this->avatar = (isset($data['avatar'])) ? $data['avatar'] : null;
    $this->user_level = (isset($data['user_level'])) ? $data['user_level'] : null;
    $this->date_registered = (isset($data['date_registered'])) ? $data['date_registered'] : null;
    $this->is_active = (isset($data['is_active'])) ? $data['is_active'] : null;
    $this->is_banned = (isset($data['is_banned'])) ? $data['is_banned'] : null;
}

    throw new \Exception('Not used');
}

        $inputFilter = new InputFilter();

当我尝试访问$ form对象的isValid()或getMessages()方法时，它们为空。当在var_dump中调用它们时，它们始终为 bool 值false ...有人可以帮我吗？提前致谢。这仅在此模块中发生。在我的其他模块中，表格一切正常。 ZF2有时是如此复杂...:|

最佳答案

我和你有同样的问题，isValid()将返回false，而getMessages()将是一个空数组。

我的问题是我已经为一个字段(例如电子邮件)定义了一个输入验证器，但是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。
