PHP:如何重命名使用 Zend_Form_Element_File 上传的文件？

Question

表格:

//excerpt
$file = new Zend_Form_Element_File('file');
$file->setLabel('File to upload:')
    ->setRequired(true)
    ->addValidator('NotEmpty')
    ->addValidator('Count', false, 1)
    ->setDestination(APPLICATION_UPLOADS_DIR);
$this->addElement($file);

Controller :

//excerpt
if ($form->isValid($request->getPost()) {
    $newFilename = 'foobar.txt';
    //how should I rename the file?
    //When should I rename the file? Before or after receiving?
    try {
        $form->file->receive();
        echo 'filename: '. $form->file->getFileName();
    }
}

问题:

1. 当我调用 $form->file->getFileName() 时，它返回完整路径，而不仅仅是文件名。如何只输出文件名？

   //Answer: First, get an array of the parts of the filename:
   $pathparts = pathinfo($form->file->getFileName());
   //then get the part that you want to use
   $originalFilename = $pathparts['basename'];
   

2. 如何将文件名重命名为我想要的名称？这可以用 Rename 过滤器来完成吗？我已经在表单中设置了目的地，所以我只想更改文件名。也许我不应该在表格中设置目的地？或者也许这不能用过滤器来完成。也许我应该用 PHP 函数来做这件事？我该怎么办？

   //Answer: Use the rename filter:
   $form->file->addFilter('Rename', 'new-file-name-goes-here.txt');
   

最终解决方案:

这就是我最终做的:

public function foobarAction()
{
    //...etc...

    if (!$form->isValid($request->getPost())) {
        $this->view->form = $form;
        return;
    }

    //the following will rename the file (I'm setting the upload dir in the form)
    $originalFilename = pathinfo($form->file->getFileName());
    $newFilename = 'file-' . uniqid() . '.' . $originalFilename['extension'];
    $form->file->addFilter('Rename', $newFilename);

    try {
        $form->file->receive();
        //upload complete!
        $file = new Default_Model_File();
        $file->setDisplayFilename($originalFilename['basename'])
            ->setActualFilename($newFilename)
            ->setMimeType($form->file->getMimeType())
            ->setDescription($form->description->getValue());
        $file->save();
    } catch (Exception $e) {
        //error: file couldn't be received, or saved (one of the two)
    }
}
