Question

更新：已解决 检查当前请求是否是一个帖子是不够的。表单仍然按创建顺序传递给帮助程序。如果传递给帮助者的第一个表单不是发布的表单，则没有足够的验证来防止使用其详细信息而不是预期的发布表单。

在帮助程序中添加了if附加条款......

if ($postId)

应该是

if ($postId === $formId)

非常直接真的......只花了我2天才找到答案。

我试图在ZF1中实现自己的PRG（Post / Redirect / Get）模式。

我使用扩展Zend_Form的自定义表单类来添加setUniqueFormId方法，该方法基本上是带有表单名称的隐藏元素。表单与2个变量（$persistData和$redirectUrl）一起传递给动作助手。问题是，当我有多个表单时，~~第一个$persistData和$redirectUrl值总是用于任何后续表单，即使这些表单已被更改。~~ 使用从最后一次调用传递给助手的值。

有关为何会出现这种情况的任何想法？任何帮助非常感谢。

更新：我认为这是使用动作助手的问题。每次调用它并传递新值时，所有先前的值都会更改。我对行动助手经纪人的内部并不熟悉。任何人都可以提出任何建议或提出建议吗？

$testForm1->setUniqueFormId('test_form_1');

Answer 1

我（愚蠢地）没有检查表单提交后表单是否传递给帮助程序是否是已发布的表单。这意味着如果发布的表单不是发布的第一个表单，则与第一个表单一起传递的值是存储在会话中的值。

if ($postId)应该是if ($postId === $formId)

public function direct($form, $persistData = false, $redirectUrl = null)
    {
    $formId = $form->getElement('unique_form_id')->getValue();

    $currentUrl = implode   (
                            '/',
                             array   (
                                     $this->getRequest()->getModuleName(),
                                     $this->getRequest()->getControllerName(),
                                     $this->getRequest()->getActionName()
                                     )
                            );

$session = new Zend_Session_Namespace('prg');

$redirectUrl = $redirectUrl ? $redirectUrl : $currentUrl;

if ($this->getRequest()->isPost())
    {
    $postId = $this->getRequest()->getPost('unique_form_id');

    if ($postId === $formId)
        {
        $redirector = Zend_Controller_Action_HelperBroker::getStaticHelper('Redirector');

        $postUrl = $currentUrl;

        $session->$postUrl->$postId = array (
                                            'url'       => (string) $redirectUrl,
                                            'id'        => (string) $postId,
                                            'post'      => (array) $this->getRequest()->getPost(),
                                            'persist'   => (bool) $persistData
                                            );

        Zend_Session::writeClose(true);

        $response = $redirector ->setCode(303)
                                ->setExit(true)
                                ->gotoUrl($redirectUrl);

        return  $response;
        }
        else    {
                return false;
                }
    }
    else    {
            $urlSessionData = $session->$currentUrl;

            // Results shown below
            Zend_Debug::dump($urlSessionData);

            if ($urlSessionData->$formId != null)
                {
                $formSessionData = $urlSessionData->$formId;
                $formPersist = $formSessionData['persist'];
                $formPostData = $formSessionData['post'];

                if (!$formPersist)
                    {
                    unset($urlSessionData->$formId);
                    }

                if(!empty($formPostData))
                    {
                    $form->isValid($formPostData);
                    }

                return $formPostData;
                }
                else    {
                        return false;
                        }
            }
