Question

我想知道是否有人可以帮助我。

我正在使用Aurigma的图片上传软件，允许用户上传他们访问过的地点的图片。信息通过以下脚本保存：

<?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”。如下所示。

  $locationfolder = $_POST['locationid'];
  $locationfolder = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $locationfolder);
  if (!is_dir($absGalleryPath . $locationfolder)) {
    mkdir($absGalleryPath . $locationfolder, 0777);
  }

我想要合并的是检查，看看是否已经设置了当前“locationid”值的文件夹，如果没有创建文件夹。我不是PHP的专家，但我知道要查看文件是否存在，可以使用if(file exists....)，但我只是想知道是否有人可以告诉我，我该怎样才能实现此检查文件夹名称？

非常感谢

我认为is_dir()正是您所寻找的。

<强>更新

您拥有的代码：

if (!is_dir($absGalleryPath . $locationfolder)) {
   mkdir($absGalleryPath . $locationfolder, 0777);
}

完全符合您的要求。它会检查文件夹，如果它不存在，则会为您创建一个（使用CHMOD 777）。不要看你的问题是什么......

创建文件夹并插入（如果不存在）
