我在usereditform上提交保存后尝试访问时收到此消息 错误信息： 在第13行的/var/www/CommunicationApp/module/Users/src/view/users/user-manager/edit.phtml中调用非对象的成员函数prepare（） 这是我的档案 任何人都可以告诉我发生了什么事吗>

Answer 1

原因是您要发布到processAction，它不会在视图模型中返回$ form。不知道为什么这会渲染编辑phtml，但这可能是问题。

可能只是想在processAction的末尾添加重定向和flash消息

$this->flashMessenger()->addSuccessMessage($this->translate('EDIT_SUCCESS'));
return $this->redirect()->toRoute('users');

如果表单未通过验证，则为

和另一个。

我可能会发布相同的动作，以便您可以轻松地完成所有验证工作。但这取决于你......在editAction中

     if ($this->getRequest()->isPost()) {
        $data = $this->getRequest()->getPost();

        $form->setData($data);

        if ($form->isValid()) {
            //saving and stuff
            $this->flashMessenger()->addSuccessMessage($this->translate('EDIT_SUCCESS'));
return $this->redirect()->toRoute('users');
         } else {
             $this->flashMessenger()->addErrorMessage($this->translate('EDIT_ERROR'));
         }
      }

Answer 2

我通过在流程操作结束时返回表单来解决它：

public function processAction(){
$post = $this->request->getPost();
$userTable = $this->getServiceLocator()->get('UserTable');
$user = $userTable->getUser($post->id);
$this->getServiceLocator()->get('UserTable')->saveUser($user);
$form = $this->getServiceLocator()->get('UserEditForm');
$form->setHydrator(new \Zend\Stdlib\Hydrator\ClassMethods());
$form->bind($user);
$form->setData($post);
return $form;
}
