写入会话的意外值

Question

更新：已解决 检查当前请求是否是帖子是不够的。这些表格仍然按照创建顺序传递给帮手。如果传递给助手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细节而不是预期的发布表单。

新增if在助手附加条款...

if ($postId) 

应该已经

if ($postId === $formId) 

漂亮的直线前进真的...我只用了2天找到答案。

我试图实现自己的PRG（邮政/重定向/获取）在ZF1模式。

我使用了一个自定义表单类，它扩展了Zend_Form来添加一个setUniqueFormId方法，它基本上是一个隐藏的表单名称。这些表格连同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，即使这些表单已更改。 使用从上次调用传递给帮助器的值。

有关为什么会出现这种情况的任何想法？任何帮助非常感谢。

更新：我认为这是使用操作助手的问题。每次调用并传递新值时，以前的所有值都会更改。我不太熟悉行动助手经纪人的内幕。任何人都可以摆脱任何光线或提出建议吗？

// Create 2 new forms

$testForm2 = new Application_Form_Test; 

// Call a custom function on each form tp create a hidden field called 
// "unique_form_id" to help identify the form that has posted the data 
$testForm1->setUniqueFormId('test_form_1'); 
$testForm2->setUniqueFormId('test_form_2'); 

// Call "Post Redirect Get" Helper and pass a boolean variable for $persistData 
$formData1 = $this->_helper->postRedirectGet($testForm1, true); 
$formData2 = $this->_helper->postRedirectGet($testForm2, false);

Answer 1

我（愚蠢的）并没有检查表单提交后传递给帮助的表单是否为张贴的表单。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就是存储在会话中的值。

if ($postId)应该已经if ($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; 
         } 
      } 
}
