download manager help

[zenny]

hi guys, i have created a simple php download manager. which i aim to use it for people to upload file to a certain folder called addon. It works on my apache svr, however when i uploaded it to my webhost it did not work out anymore.. below is my code.. uploaded to my website.

<?php

define ("FILEDIRECTORY", "/addon");
$MaxSize = 5000;
$noFilename = "";
$getFilename = $_REQUEST['name'];

//check if it is posted by the form, and name field is entered
if (is_uploaded_file($_FILES['addon']['tmp_name'])) {

if($_FILES['addon']['size'] > $MaxSize) { //check max file size

echo "<p> Max File Size Exceeded 5mb, please try again or contact [email protected].</p>";

}

else if ($getFilename == $noFilename) { //check that filename is entered

echo "<p>Please enter a File name for upload</p>";
}

else if ($_FILES['addon']['type'] != "application/x-zip-compressed") {
            //check that the correct format is entered
echo "Please zip up your file with WinZip";
} else { 

$name = $_POST['name'];

//upload zip file.
$result = move_uploaded_file($_FILES['addon']['tmp_name'], FILEDIRECTORY."/$name.zip");
$desc = $_REQUEST['Discribe'];

//opening text file to write and save discription.
$resource = fopen(FILEDIRECTORY."/$name.txt", "wt");
fwrite($resource, $desc, "15000");
fclose($resource);
if ($result == 1)  {


//display uploaded item.
$uploadDESC = fopen(FILEDIRECTORY."/$name.txt", "r");
$theData = fread($uploadDESC, "15000");
fclose($uploadDESC);
echo "<p> File Uploaded Successfully.</p>";
echo "<p> You have uploaded $name.zip with the description below : </p>";
echo "<p> $theData </p>";

}
else echo "<p> There was a problem, during uploading process.</p>";
} #endIF

  }#endIF
