如何使用PHP和Zend Framework进行文件上传？

形成：

<?PHP

class Default_Form_UploadFile extends Zend_Form
{
    public function init()
    {
        $this->setAttrib('enctype','multipart/form-data');
        $this->setMethod('post');

        $description = new Zend_Form_Element_Text('description');
        $description->setLabel('Description')
            ->setrequired(true)
            ->addValidator('NotEmpty');
        $this->addElement($description);

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

        $this->addElement('submit','submit',array(
            'label'    => 'Upload','ignore'   => true
        ));
    }
}

控制器：

public function uploadfileAction()
{
    $form = new Default_Form_UploadFile();
    $form->setAction($this->view->url());

    $request = $this->getRequest();

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

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

    try {
        $form->file->receive();
        //upload complete!
        //...what Now?
        $location = $form->file->getFileName();
        var_dump($form->file->getFileInfo());
    } catch (Exception $exception) {
        //error uploading file
        $this->view->form = $form;
    }
}

现在我该怎么做文件？默认情况下已将其上传到我的/ tmp目录.显然这不是我想要保留的地方.我希望我的应用程序的用户能够下载它.所以,我认为这意味着我需要将上传的文件移动到我的应用程序的公共目录,并将文件名存储在数据库中,以便我可以将其显示为一个url.

或者将其设置为上传目录(尽管我以前尝试执行此错误)).

你之前使用过上传的文件吗？我应该下一步是什么？

解：

我决定将上传的文件放入数据/上传(这是一个到我应用程序之外的目录的sym链接,以便使我的应用程序的所有版本都可以访问).

# /public/index.PHP
# Define path to uploads directory
defined('APPLICATION_UPLOADS_DIR')
    || define('APPLICATION_UPLOADS_DIR',realpath(dirname(__FILE__) . '/../data/uploads'));

# /application/forms/UploadFile.PHP
# Set the file destination on the element in the form
$file = new Zend_Form_Element_File('file');
$file->setDestination(APPLICATION_UPLOADS_DIR);

# /application/controllers/MyController.PHP
# After the form has been validated...
# Rename the file to something unique so it cannot be overwritten with a file of the same name
$originalFilename = pathinfo($form->file->getFileName());
$newFilename = 'file-' . uniqid() . '.' . $originalFilename['extension'];
$form->file->addFilter('Rename',$newFilename);

try {
    $form->file->receive();
    //upload complete!

    # Save a display filename (the original) and the actual filename,so it can be retrieved later
    $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
}
