Php 创建文件夹并插入（如果不存在）

不知是否有人能帮助我

我使用Aurigma的图像上传软件，允许用户上传他们访问的地点的图像。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();
?>

我想合并的是一个检查，看看是否有一个文件夹已经设置为当前的'locationid'值，如果没有创建文件夹。我不是PHP方面的专家，但我知道要检查文件是否存在，可以使用

if（file exists…）

，但我只是想知道是否有人可以告诉我如何对文件夹名执行此检查

非常感谢

克里斯

我想这就是你要找的

更新：

您拥有的代码：

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

---

这正是你想要的。它会检查文件夹，如果它不存在，则会为您创建一个文件夹（使用CHMOD 777）。看不出你的问题是什么…

非常感谢你的澄清。我必须承认，我不是100%确定整个代码段实际上做了什么。因为我对这方面比较陌生，所以我做了一个“复制粘贴”，只是改变了我认为需要做的事情。但是从那些有更多知识的人那里得到一些指导是很好的。当做

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