Question

我使用Zend Form并上传文件。我需要为它重命名和用户addFilter。但是，如果我尝试在代码中获得文件的扩展名，我会收到错误“文件太多，允许最大'1'但是给出'2'”。如果我尝试使用$ _FILES进行扩展，看起来它可以解决但看起来很难看。你能告诉我如何重命名文件保存它的扩展名吗？

        $form = new Form_ImportSubscribers();               
        if ($this->getRequest()->isPost()) {
            $formData = $this->getRequest()->getPost();
            if ($form->isValid($formData)) {
                //it looks like it works but it's ugly solution
//              $extension = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION); 
                //causes an error "Too much files, maximum '1' are allowed but '2' are given"           
                $extension = pathinfo($form->file->getFileName(), PATHINFO_EXTENSION);              
                $form->file->addFilter('Rename', $accountId . '_' . time() .  '.' . $extension);

                if (!$form->file->receive()) {
                    $this->view->form = $form;
                    $this->view->listName = $list->list_name;                                   
                    return;
                }

如果$ form-＆gt; file-＆gt; getFileName（）返回多个值，我假设你上传了多个文件。在这种情况下，您可以应用重命名过滤器并接收单个文件，如下所示：

/*@var $adapter Zend_File_Transfer_Adapter_Http */
$adapter =  $form->file->getTransferAdapter();
$receivingOK = true; 
foreach ($adapter->getFileInfo() as $file => $info) {                                     
    $extension = pathinfo($info['name'], PATHINFO_EXTENSION); 
    $adapter->addFilter('Rename', $accountId . '_' . time() .  '.' . $extension, $file);
    if (!$adapter->receive($file)) {
         $receivingOK = false;
    }
}

if (!$receivingOK) {
    $this->view->form = $form;
    $this->view->listName = $list->list_name;                                   
    return;
}

即使您不执行多个文件上传，它也应该工作。

这是我在控制器中的代码，它适用于Zend 1.11：

$uploadForm = new Application_Form_DeckblattUpload();
$front = $uploadForm->getElement('front');
/* @var $front Zend_Form_Element_File */
$tfa = $front->getTransferAdapter();
/* @var $tfa Zend_File_Transfer_Adapter_Abstract */
$tfa->addFilter('Rename', array(
    'target' => APPLICATION_PATH .'/public/dir/somepath.jpg',
    'overwrite' => true));

$back = $uploadForm->getElement('back');
/* @var $front Zend_Form_Element_File */
$tfa = $back->getTransferAdapter();
/* @var $tfa Zend_File_Transfer_Adapter_Abstract */
$tfa->addFilter('Rename', array(
    'target' => APPLICATION_PATH . '/public/someOtherDir/somepath.jpg',
     'overwrite' => true));

if ($this->getRequest()->upload) {
    if ($uploadForm->isValid($this->getRequest()->getParams())) {
        $uploadForm->getValues(); //<- this does the uploading
        //Success-Message
    }
    else {
        //Failure-Message
    }
}
$this->view->uploadForm = $uploadForm;

表单只包含2个Zend_Form_Elements_Files（“后退”和“前面”）和提交按钮（“上传”）。

我希望这可以让您了解如何使用重命名过滤器并仍然使用$ form-＆gt; isValid（）。不要混淆http://framework.zend.com/manual/en/zend.file.transfer.filters.html和http://framework.zend.com/manual/en/zend.filter.input.html

另请注意，您不能在装饰器中使用'viewHelper'作为文件元素。而是使用'文件'。希望这仍然有帮助。

尝试使用以下内容：

$upload = new Zend_File_Transfer();
// use setDestination, addValidator etc
$files = $upload->getFileInfo();
foreach ($files as $file => $info) {
    $file = '/path/to/file/name.ext';
    $upload->addFilter('Rename', $file);
    //Do rest of code
}
$upload->receive();
