寫入會話的意外值

Question

更新：已解決 檢查當前請求是否是帖子是不夠的。這些表格仍然按照創建順序傳遞給幫手。如果傳遞給助手的第一個表單不是發佈的表單，則沒有足夠的驗證來防止使用其細節而不是預期的發佈表單。

新增if在助手附加條款...

if ($postId) 

應該已經

if ($postId === $formId) 

漂亮的直線前進真的...我只用了2天找到答案。

我試圖實現自己的PRG（郵政/重定向/獲取）在ZF1模式。

我使用了一個自定義表單類，它擴展了Zend_Form來添加一個setUniqueFormId方法，它基本上是一個隱藏的表單名稱。這些表格連同2個變量（$persistData和$redirectUrl）一起傳遞給動作助手。 問題是，當我有多個表單時， 第一個 $persistData和 $redirectUrl值總是用於任何後續表單，即使這些表單已更改。 使用從上次調用傳遞給幫助器的值。

有關爲什麼會出現這種情況的任何想法？任何幫助非常感謝。

更新：我認爲這是使用操作助手的問題。每次調用並傳遞新值時，以前的所有值都會更改。我不太熟悉行動助手經紀人的內幕。任何人都可以擺脫任何光線或提出建議嗎？

// Create 2 new forms 
$testForm1 = new Application_Form_Test; 
$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）並沒有檢查表單提交後傳遞給幫助的表單是否爲張貼的表單。這意味着如果發佈的表單不是發佈的第一個表單，則與第一個表單一起傳遞的值就是存儲在會話中的值。

if ($postId)應該已經if ($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; 
         } 
      } 
}
