【问题描述】：

我对 Zend 和 Doctrine 很陌生

使用 ORM 为 Zend 创建一个模块，但是当我发布时，没有设置数据。

我检查了this，但没有运气。

我的module.config.php

<?php

return array(
    'controllers' => array(
        'invokables' => array(
            'Room\Controller\Index' => 'Room\Controller\IndexController',
        ),
    ),
    'router' => array(
                //other stuff
                //
                ),
                'may_terminate' => true,
            ),
        ),
    ),
    'view_manager' => array(
        'display_exceptions' => true,
        'template_path_stack' => array(
            'room' => __DIR__ . '/../view'
        ),
    ),
    'service_manager' => array (
        'factories' => array(
            'room_module_options' => 'Room\Service\Factory\ModuleOptionsFactory',
            'room_error_view' => 'Room\Service\Factory\ErrorViewFactory',
            'room_form' => 'Room\Service\Factory\RoomFormFactory',
        ),
    ),
    'doctrine' => array(
        'configuration' => array(
            'orm_default' => array(
                'generate_proxies' => true,
            ),
        ),
        
        'driver' => array(
            'room_driver' => array(
                'class' => 'Doctrine\ORM\Mapping\Driver\AnnotationDriver',
                'cache' => 'array',
                'paths' => array(
                    __DIR__ . '/../src/Room/Entity',
                ),
            ),
            'orm_default' => array(
                'drivers' => array(
                    'Room\Entity' => 'room_driver',
                ),
            ),
        ),
    ),
);

我在Entity 文件夹中有我的Room.php 文件，并且拥有所有getter/setters 方法以及ORM 设置。运行schema:update 也可以工作并将新表添加到数据库中。

问题

当我提交表单时，它不会更新表格，因为所有帖子数据都是空的。我还通过var_dump($request->getPost()) 测试了它是否正在发布，它会返回所有传递的数据。但是，当我在 $form->isValid() 之后检查 var_dump($form->getData()); 时，它会返回所有 NULL 数据。

检查了一整天，尽我所能，但没有任何运气。请帮忙。

我猜Form 文件有问题，但不确定。

【参考方案1】：

好吧，终于经过几天缩小问题找到了解决方案。

基本上我在 Entity 类中有错误的语法。我用"_" 声明了我的变量，这导致了问题，因为我的getter 和setter 没有调用它。

例如，我有像 $room_code 这样的变量，我的这个变量的 getter/setter 是：

public function setRoomCode($room_code)

   $this->room_code = $room_code;
   return $this;


public function getRoomCode()

   return $this->room_code;

Zend 的正确做法

$roomCode; //declaring variable.

//setter
public function setRoomCode($roomCode)
    
       $this->roomCode = $roomCode;
       return $this;
    

//getter
public function getRoomCode()
    
       return $this->roomCode;
    

真的很可怜我，但我想它给了我很好的时间来学习 zend 和 orm 如何协同工作。

我希望这将在不久的将来帮助某人。

【参考方案2】：

尝试改变这两行

$form->setData($request->getPost());
if ($form->isValid()) 

到

//$form->setData($request->getPost());
if ($form->isValid($request->getPost())) 

【讨论】：

有了这个，它根本不发送数据。它不断询问字段是必需的。
