Custom File upload locations

[nextgengames]

Hey All,

Im trying to upload a file and in the process rename it. On the form the user selects the file and where they want to store it then clicks submit.

If I just use the example under the move_uploaded_file() function on php.net it works fine. The issue seems to come when i try to manipulate the upload location. Code is below and any help as alyways greatfully appreciated.

Kevin

<?php
session_start();
header("Cache-control: private");
require_once '../../global.php';

 if(!empty($_FILES["userfile"]))
  {
$dest = $_POST['destination'];
$name = "apples.jpg";
$uploaddir = "../../images/";
$uploaddir.=$dest.$name;

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploaddir)) {
   $_SESSION["toast"] = "<div class=\"toast\">The file has been moved byte by byte to its new home in the big cloud</div>";
	header('Location: ../images.php');
} else {
   $_SESSION["toast"] = "<div class=\"toast\">File Attack Detected</div>";
	header('Location: logout.php');
}
} else {
	$_SESSION["toast"] = "<div class=\"toast\">No file was selected</div>";
	header('Location: ../images.php');
}
?>

By chance are your paths relative to the file system or relative to the webserver root?

Id assume files system. The php file is in beta/admin/process the images direcs are in beta/images.

if i use a static address eg ../../images/library it works, its just as soon as i try to change it on the fly.

Try prepending

$_SERVER['DOCUMENT_ROOT']

to your paths where file manipulation is implied. For example, refer to images with

$uploaddir = $_SERVER['DOCUMENT_ROOT'] . "/beta/images/";

. Now, for my "voodoo" statement as I'm too lazy to research this 😃. It seems like PHP can use relative paths for some functions, but requires absolute paths for others. For example, perhaps, because PHP knows when you are using a require statement, PHP can prepend the document root on its own, because PHP understands you are including a file in the virtual server root context. However, PHP wants a "solid" absolute path for file manipulation (I could have researched this out in the time it took for me to write this.) Nonetheless, get used to the idea that a webserver virtual root and the filesystem root are not the same. For example, for domain.com, I should be able to show imagex via html <img src="/imagex">. That path is relative to the virtual root for domain.com. However, in the file system, the absolute path might be /var/www/domain/imagex.
