zend框架窗体上传编辑问题

我的问题是编辑窗体中的信息时，所有的信息，但file_path是空的，所以当你点击提交发生的更新设置file_path为空。

我只想在加载时查看可编辑项目的路径，所以当您单击提交时，旧路径将在那里。

public function EditaddAction() { 

    $session = new Zend_Session_Namespace('user'); 
    $userid = $session->id; 
    // in case the request was an edit request 
    $id = (int) $this->_request->getParam('id'); 
    //The incoming request 
    $request = $this->getRequest(); 
    //initialize form 
    $form = new Admin_Form_Banner(); 
    //uploaded file settings 
    $file = $form->file_path; 
    $file->setDestination(ZendX_Image::getFullUploadPath() . '/files/get/original/'); 
    //instance of db 
    $db = Zend_Db_Table::getDefaultAdapter(); 

    if ($this->getRequest()->isPost()) { 
     if ($form->isValid($request->getPost())) { 

      $dbFilePath = "/files/get/original/" . $file->getFileName(null, false); 


      //code to get the duration of the video 
      $sourceVideo = PUBLIC_PATH . $form->getValue('file_path'); 
      ob_start(); 
      passthru("ffmpeg -i \"" . $sourceVideo . "\" 2>&1"); 
      $duration = ob_get_contents(); 
      ob_end_clean(); 
      preg_match('/Duration: (.*?),/', $duration, $matches); 
      $duration = $matches[1]; 
      $duration_array = preg_split('[:]', $duration); 
      $duration = $duration_array[0] * 3600 + $duration_array[1] * 60 + $duration_array[2]; 

      die($time); 
      end of code to get the duration of the video 
      if (isset($id) && $id != "" && $file->receive()) { 
       try { 
        $db->update('banner', array('banner_title' => $form->getValue('banner_title'), 
         'banner_type' => $form->getValue('banner_type'), 
         'banner_position' => $form->getValue('banner_position'), 
         'banner_link' => $form->getValue('banner_link'), 
         'link_open' => $form->getValue('link_open'), 
         'file_path' => $dbFilePath, 
         'is_active' => $form->getValue('is_active') 
          ), array('id =?' => $id)); 
        $this->flash('Banner Updated', 'admin/banner'); 
       } catch (Exception $e) { 
        $this->flash($e->getMessage(), 'admin/banner'); 
       } 
      } else { 
       try { 

        $db->insert('banner', array('banner_title' => $form->getValue('banner_title'), 
         'banner_type' => $form->getValue('banner_type'), 
         'banner_position' => $form->getValue('banner_position'), 
         'banner_link' => $form->getValue('banner_link'), 
         'link_open' => $form->getValue('link_open'), 
         'file_path' => $dbFilePath, 
         'is_active' => $form->getValue('is_active'), 
         'created_by' => $userid, 
         'date_ceated' => date('Y/m/d H:i:s'), 
         'is_deleted' => 0, 
        )); 
        $this->flash('Banner Added', 'admin/banner'); 
       } catch (Exception $e) { 
        $this->flash($e->getMessage(), 'admin/banner'); 
       } 
      } 
     } 
    } 

    if (isset($id) && $id != "") { 
     $checkvalues = $db->fetchCol($db->select()->from(array('banner'),array('file_path'))); 
     $values = $db->fetchRow("SELECT * FROM banner WHERE id = ?", $id); 
     $values['file_path'] = $checkvalues; 
     $form->populate($values); 
    } 

    $this->view->form = $form;

我会将该描述编辑为多个句子和段落，以便人们有机会阅读它！ – Treffynnon 2011-05-12 12:24:49

在更新时不要覆盖数据库中的值，除非它已被提供？ – Treffynnon 2011-05-12 12:35:37

我这样做仍然是相同的问题 – haider 2011-05-12 12:41:37

当你说路径你的意思是在http客户端的路径？您无权访问该文件。

如果你的问题是关于文件路径上传您可以按以下做后：

1）的元素必须是Zend_Form_Element_File。

2）控制器：

$form->file_path->receive(); //this will return true if the file was successfully received and false if not 
$file_path_on_server = $form->file_path->getFileName(); // there you get the file name

该文件将保持其原来的名字。

当我尝试你的第一个代码和var_dump它。我得到了一个虚假的信息，这意味着它正在检索什么，你知道为什么吗？ – haider 2011-05-13 18:43:18

错误表示文件未成功接收。不要忘记设置Zend_Form_Element_File的目的地（_ $ element-> setDestination（'path'）_） – pantunas 2011-06-02 13:44:05

我遇到了同样的问题。我解决它使用一个隐藏字段，形式，我在其中存储的文件名，并在修改操作使用

some action code 
if ($request->isPost()) { 
       if ($form->isValid($request->getPost())) { 
        if ('administrator' == $user->role) { 
         $oldFileName = $form->getElement('oldfilename')->getValue(); //the hidden field 
         $data = $form->getValues(); 
         $model->populate($data); 
        if (file_exists('uploads/cv/' . $oldFileName)) { 
          $form->getElement('cv')->setIgnore(true); //this is my Form File Element - the file exists, I don't need to store the filename 
         } else { // if you want you can unlink $oldFileName 
          $upload = new Zend_File_Transfer_Adapter_Http(); 
          $info = $upload->getFileInfo('cv'); 
          $upload->setDestination("uploads/cv/"); 
          if (file_exists('uploads/cv/' . $info['cv']['name'])) { 
           $newFileName = time() . rand(0, 100000) . "-" . $info['cv']['name']; // I need to avoid overwriting file 
          } else { 
           $newFileName = $info['cv']['name']; 
           $upload->addFilter('Rename', $newFileName); 
          } 
          try { 
           $upload->receive(); 
          } catch (Zend_File_Transfer_Exception $e) { 
           $e->getMessage(); 
          } 
         } 
         $model->save(); 
         return $this->_helper->redirector('list'); 
        } else { 
         //some error message 
         $this->_helper->redirector('list'); 
        } 
       } else { //form not valid 
        $this->view->form = $form; 
       } 
      } else { 
       $model->find($id); 
       $data = array(); 
       $data = $model->toArray(); 
       $data['oldfilename'] = $model->get_cv(); //the filename stored in db 
       $form->getElement('cv')->setRequired(false); 
       $form->populate($data); 
       $this->view->form = $form; 
      }

肯定有很多事情可以固定一个更好的编程..
