Use Field Values For Filepath - php

Question

I wonder whether someone may be able to help me please.
I'm trying to load an xml file with the following filepath:
/UploadedFiles/username/location/files.xml
What I've been trying to do for some time, is to use the values of two forms fields, 'username' and 'location' and incorporate them into the filepath, but I just can't seem to get this right.
I just wondered whether someone could someone perhaps tell me how I take these values and use them in the filepath.
Many thanks
POST AMENDMENT
I thought I could solve my issues by simply changing the file path, hence my original post, but I fear my lack of PHP knowledge as let me down and I suspect the issues I have are deeper within my code.
Please find below more detail.
The script below shows how I initially save the images.
'upload.php'
<?php
require_once 'Includes/gallery_helper.php';
require_once 'ImageUploaderPHP/UploadHandler.class.php';
$galleryPath = 'UploadedFiles/';
function onFileUploaded($uploadedFile) {
global $galleryPath;
$packageFields = $uploadedFile->getPackage()->getPackageFields();
$username=$packageFields["username"];
$locationid=$packageFields["locationid"];
$username = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $_POST['username']);
$location = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $_POST['locationid']);
$dirName = preg_replace('/[^a-z0-9_\-\.()\[\]{}]/i', '_', $_POST['folder']);
$absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR . $username . DIRECTORY_SEPARATOR . $location . DIRECTORY_SEPARATOR;
$absThumbnailsPath = $absGalleryPath . 'Thumbnails' . DIRECTORY_SEPARATOR;
if (!is_dir($absGalleryPath)) mkdir($absGalleryPath, 0777, true);
chmod($absGalleryPath, 0777);
if (!is_dir($absGalleryPath . $dirName)) mkdir($absGalleryPath . $dirName, 0777, true);
chmod($absGalleryPath . $dirName, 0777);
if ($uploadedFile->getPackage()->getPackageIndex() == 0 && $uploadedFile->getIndex() == 0)
initGallery($absGalleryPath, $absThumbnailsPath, FALSE);
$originalFileName = $uploadedFile->getSourceName();
$files = $uploadedFile->getConvertedFiles();
$sourceFileName = getSafeFileName($absGalleryPath, $originalFileName);
$sourceFile = $files[0];
if ($sourceFile) $sourceFile->moveTo($absGalleryPath . $sourceFileName);
$thumbnailFileName = getSafeFileName($absThumbnailsPath, $originalFileName);
$thumbnailFile = $files[1];
if ($thumbnailFile) $thumbnailFile->moveTo($absThumbnailsPath . $thumbnailFileName);
$descriptions = new DOMDocument('1.0', 'utf-8');
$descriptions->load($absGalleryPath . 'files.xml');
$xmlFile = $descriptions->createElement('file');
// <-- please check the following line
$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());
$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();
?>
This script produces the following file structure:
UploadedFiles (Pre-existing folder)
'username' (Subfolder containing 'location' folder)
'location' (Subfolder containing original image, 'files.xml' and 'Thumbnails' folder)
'Thumbnails' (Subfolder containing thumbnail of original image)
NB. The 'username' and 'location folder names are derived from the current user and location values.
I then come onto my issue with the creation of the image gallery.
The code below is my initial 'gallery.php' script. I need to change the top PHP section of the script to match the new folder structure i.e. UploadedFiles/'username'/'location'/Thumbnails and UploadedFiles/'username'/'location'.files.xml
'gallery.php'
<?php
$galleryPath = 'UploadedFiles/';
$thumbnailsPath = $galleryPath . 'Thumbnails/';
$absGalleryPath = realpath($galleryPath) . DIRECTORY_SEPARATOR;
$descriptions = new DOMDocument('1.0');
$descriptions->load($absGalleryPath . 'files.xml');
?>

I admit to being at a real loss at how to solve this, I don't whether it's my 'gallery.php' script that needs to change or my 'upload.php'
Any help would be so gratefully received.
Kind regards

Answer 1

OK, let's say you have this values : username, location.
Then, (if I get your question right) in the responding script (the one receiving the form action), try this :
<?php
$username = $_GET['username'];
$location = $_GET['location'];
$filepath = "/UploadedFiles/$username/$location/files.xml";
?>
Hint (2 ways of concatenating strings) :
$filepath = "/UploadedFiles/$username/$location/files.xml";
OR
$filepath = "/UploadedFiles/".$username."/".$location."/files.xml";

Answer 2

This will work regardless you are using post or get method in your form . Just make sure you choose field name username and location for input text html element.
$filepath = "/UploadedFiles/{$_REQUEST['username']}/{$_REQUEST['location']}/files.xml"

Answer 3

You have to define them as variable and include within the string
$username = "user1";
$location = "userlocation1";
$url = "/UploadedFiles/$username/$location/files.xml";
//Next you might want to verify the location
if(is_file($url)) {
//do your operation....
}
