我想知道是否有人可以帮助我。
我正在使用 Aurigma 的图像上传器软件来允许用户上传他们访问的位置的图像。信息通过如下所示的脚本保存:
<?php
//This variable specifies relative path to the folder, where the gallery with uploaded files is located.
//Do not forget about the slash in the end of the folder name.
$galleryPath = 'UploadedFiles/';
require_once 'Includes/gallery_helper.php';
require_once 'ImageUploaderPHP/UploadHandler.class.php';
/**
* FileUploaded callback function
* @param $uploadedFile UploadedFile
*/
function onFileUploaded($uploadedFile) {
$packageFields = $uploadedFile->getPackage()->getPackageFields();
$username=$packageFields["username"];
$locationid=$packageFields["locationid"];
global $galleryPath;
$absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR;
$absThumbnailsPath = $absGalleryPath . 'Thumbnails' . DIRECTORY_SEPARATOR;
if ($uploadedFile->getPackage()->getPackageIndex() == 0 && $uploadedFile->getIndex() == 0) {
initGallery($absGalleryPath, $absThumbnailsPath, FALSE);
}
$locationfolder = $_POST['locationid'];
$locationfolder = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $locationfolder);
if (!is_dir($absGalleryPath . $locationfolder)) {
mkdir($absGalleryPath . $locationfolder, 0777);
}
$dirName = $_POST['folder'];
$dirName = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $dirName);
if (!is_dir($absGalleryPath . $dirName)) {
mkdir($absGalleryPath . $dirName, 0777);
}
$path = rtrim($dirName, '/\\') . '/';
$originalFileName = $uploadedFile->getSourceName();
$files = $uploadedFile->getConvertedFiles();
// save converter 1
$sourceFileName = getSafeFileName($absGalleryPath, $originalFileName);
$sourceFile = $files[0];
/* @var $sourceFile ConvertedFile */
if ($sourceFile) {
$sourceFile->moveTo($absGalleryPath . $sourceFileName);
}
// save converter 2
$thumbnailFileName = getSafeFileName($absThumbnailsPath, $originalFileName);
$thumbnailFile = $files[1];
/* @var $thumbnailFile ConvertedFile */
if ($thumbnailFile) {
$thumbnailFile->moveTo($absThumbnailsPath . $thumbnailFileName);
}
//Load XML file which will keep information about files (image dimensions, description, etc).
//XML is used solely for brevity. In real-life application most likely you will use database instead.
$descriptions = new DOMDocument('1.0', 'utf-8');
$descriptions->load($absGalleryPath . 'files.xml');
//Save file info.
$xmlFile = $descriptions->createElement('file');
$xmlFile->setAttribute('name', $_POST['folder'] . '/' . $originalFileName);
$xmlFile->setAttribute('source', $sourceFileName);
$xmlFile->setAttribute('size', $uploadedFile->getSourceSize());
$xmlFile->setAttribute('originalname', $originalFileName);
$xmlFile->setAttribute('thumbnail', $thumbnailFileName);
$xmlFile->setAttribute('description', $uploadedFile->getDescription());
//Add additional fields
$xmlFile->setAttribute('username', $username);
$xmlFile->setAttribute('locationid', $locationid);
$xmlFile->setAttribute('folder', $dirName);
$descriptions->documentElement->appendChild($xmlFile);
$descriptions->save($absGalleryPath . 'files.xml');
}
$uh = new UploadHandler();
$uh->setFileUploadedCallback('onFileUploaded');
$uh->processRequest();
?>
除了原始脚本之外,我还添加了创建文件夹的代码,其名称基于当前的“locationid”。这如下所示。
$locationfolder = $_POST['locationid'];
$locationfolder = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $locationfolder);
if (!is_dir($absGalleryPath . $locationfolder)) {
mkdir($absGalleryPath . $locationfolder, 0777);
}
我喜欢合并的是一个检查,看看是否有一个文件夹已经设置了当前的'locationid'值,如果没有创建文件夹。我绝对不是PHP专家,但我知道要检查文件是否存在,if(file exists....)
可以使用,但我只是想知道是否有人可以告诉我如何实现对文件夹名称的检查?
非常感谢
