我正在使用 Zend Framework 1.9.6。我想我已经明白了,除了结尾。这是我到目前为止所拥有的:
形式:
<?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;
}
}
现在我该怎么处理这个文件?它已/tmp
默认上传到我的目录。显然这不是我想保留的地方。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 url。
或者首先将其设置为上传目录(尽管我之前尝试这样做时遇到了错误)。
您以前处理过上传的文件吗?我应该采取的下一步是什么?
解决方案:
我决定将上传的文件放入data/uploads
(这是一个指向我的应用程序外部目录的符号链接,以便我的应用程序的所有版本都可以访问它)。
# /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
}
