我正在使用zend表格上传图片。
我的问题是当表单中的信息编辑时，表单中包含所有信息，但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'),
'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;

当你说路径是指http客户端中的路径？ 您无权访问。
如果您的问题与上传后文件的路径有关，则可以执行以下操作：
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。

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......

assim da certo
