ZF2-如何在现有的控制器中添加一个新的窗体

我有一个带有筛选器LoginFilter.php的登录表单LoginForm.php，它有一个视图/login/index.phtml、一个控制器LoginController.php、两个工厂LoginControllerFactory.php&CCD_ 6，在CCD_。表单正确显示。

我有一个ViewController.php，它有一个方法idAction，它通过主页上名为/view/id.phtml的参数传递的id来显示帖子。我想在此视图中显示我创建的表单，但我不知道如何显示。首先，我创建了与创建登录表单完全相同的表单，但我意识到我已经在view路由内配置了id子路由，并在module.config.php中配置了Factory。

然后，我尝试在idAction方法中设置表单，就像在LoginController.php控制器中的indexAction中一样，但我收到了以下错误：An exception was raised while creating "Rxe'Factory'ViewController"; no instance returned。

我现在将向您展示我尝试显示此新表单时所做的操作。

首先，表单本身：

class CommentForm extends Form
{
    public function buildForm()
    {
        $this->setAttribute('method', 'POST');
        $this->setAttribute('id', 'add-comment-form');
        $this->add(array(
            'name' => 'comment',
            'type' => 'textarea',
            'options' => array(
                'label' => 'Category'
            ),
            'attributes' => array(
                'class' => 'form-control'
            )
        ));
        $this->add(array(
            'name' => 'submit',
            'type' => 'submit',
            'attributes' => array(
                'class' => 'btn btn-success',
                'value' => 'Comment'
            )
        ));
    }
}

Form的CommentFormFactory.php调用其Filter并构建Form:

class CommentFormFactory implements FactoryInterface
{
    public function createService(ServiceLocatorInterface $serviceLocator)
    {
        $form = new CommentForm();
        $form->setInputFilter($serviceLocator->get('Rxe'Factory'CommentFilter'));
        $form->buildForm();
        return $form;
    }
}

ViewControllerFactory.php调用CommentFormFactory.php，就像在LoginControllerFactory.php:中一样

class ViewControllerFactory implements FactoryInterface
{
    public function createService(ServiceLocatorInterface $serviceLocator)
    {
        $serviceManager = $serviceLocator->getServiceLocator();
        $viewController = new ViewController();
        $viewController->setPostsTable($serviceManager->get('Rxe'Factory'PostsTable'));
        $viewController->setCommentsTable($serviceManager->get('Rxe'Factory'CommentsTable'));
        $viewController->setCommentForm($serviceManager->get('Rxe'Factory'CommentForm'));
        return $viewController;
    }
}

ViewController.php，在其idAction的ViewModel:中调用表单

class ViewController extends AbstractActionController
{
    use PostsTableTrait;
    use CommentsTableTrait;
    private $commentForm;
    function setCommentForm($commentForm)
    {
        $this->commentForm = $commentForm;
    }
    public function indexAction()
    {
        $category = $this->params()->fromRoute('category');
        return new ViewModel(array(
            'posts' => $this->postsTable->getPostsByCategory($category),
            'categories' => $category
        ));
    }
    public function idAction()
    {
        $id = $this->params()->fromRoute('id');
        $viewModel = new ViewModel(array(
            'commentForm' => $this->commentForm,
            'commentParams' => $this->params()->fromPost(),
            'messages' => $this->flashMessenger()->getMessages(),
            'posts' => $this->postsTable->getPostById($id),
            'posts' => $this->commentsTable->getNumberOfCommentsByPost($id),
            'comments' => $this->commentsTable->getCommentsByPost($id)
        ));
        $viewModel->setTemplate('rxe/view/id.phtml');
        if ($this->getRequest()->isPost()) {
            $this->commentForm->setData($this->params()->fromPost());
            if ($this->commentForm->isValid()) {
                $this->flashMessenger()->addMessage('Thank you for your comment. :)');
            } else {
                $this->flashMessenger()->addMessage('Your comment wasn''t sent.');
            }
        }
        return $viewModel;
    }
}

最后是我的module.config.php

'controllers' => array(
    'invokables' => array(
        'Rxe'Controller'Index' => 'Rxe'Controller'IndexController',
        'Rxe'Controller'View' => 'Rxe'Controller'ViewController',
        'Rxe'Controller'Login' => 'Rxe'Controller'LoginController'
    ),
    'factories' => array(
        'Rxe'Factory'LoginController' => 'Rxe'Factory'LoginControllerFactory',
        'Rxe'Factory'ViewController' => 'Rxe'Factory'ViewControllerFactory',
        'Rxe'Factory'IndexController' => 'Rxe'Factory'IndexControllerFactory'
    )
),
'service_manager' => array(
    'factories' => array(
        'Rxe'Factory'LoginForm' => 'Rxe'Factory'LoginFormFactory',
        'Rxe'Factory'LoginFilter' => 'Rxe'Factory'LoginFilterFactory',
        'Rxe'Factory'CommentForm' => 'Rxe'Factory'CommentFormFactory',
        'Rxe'Factory'CommentFilter' => 'Rxe'Factory'CommentFilterFactory',
        'Rxe'Factory'PostsTable' => 'Rxe'Factory'PostsTableFactory',
        'Rxe'Factory'CategoriesTable' => 'Rxe'Factory'CategoriesTableFactory',
        'Rxe'Factory'CommentsTable' => 'Rxe'Factory'CommentsTableFactory',
        'Zend'Db'Adapter'AdapterService' => 'Zend'Db'Adapter'AdapterServiceFactory'
    )
),

如果你需要我给你看更多的代码，请告诉我。提前谢谢。

编辑#1

如果我删除ViewControllerFactory.php中调用Form的行，我会得到以下错误：Fatal error: Call to a member function prepare() on a non-object in /home/vol12_3/byethost4.com/b4_16354889/htdocs/module/Rxe/view/rxe/view/id.phtml on line 31

id.phtml是：

<!-- Comment form -->
<div id="comment-form-area" class="col-xs-3">
    <?php $this->commentForm->prepare() ?>
    <?php echo $this->form()->openTag($this->commentForm); ?>
    <div class="form-group comment-area">
        <?php echo $this->formRow($this->commentForm->get('comment_content')); ?>
    </div>
    <div class="form-group">
        <?php echo $this->formRow($this->commentForm->get('submit')); ?>
    </div>
    <?php echo $this->form()->closeTag(); ?>
</div>
<!-- /Comment form -->
