我正在使用zend表单上传图片。

我的问题是在表单中编辑信息时，表单附带了所有信息，但是 file_path 为空，因此当您单击提交发生的更新时，将 file_path 设置为 null。

我只想在加载时查看可编辑项目的路径，因此当您单击提交时，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'),

                        '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,

                }
            }
        }
    }

    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;

我遇到了同样的问题。我通过在表单中​​使用隐藏字段来解决它，我在其中存储文件名并在修改操作中使用它

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;
            }

当然，为了更好的编程，有很多事情可以修复......

当您说路径时，您的意思是http客户端中的路径？你无权访问它。

如果您的问题是关于上传后文件的路径，您可以执行以下操作：

1) 元素必须是 Zend_Form_Element_File。

2）在控制器中：

$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

该文件将保留其原始名称。
