opening an uploaded file in server

[lindaonline15]

hi all. I have an upload page that uploads some files in my WAMP server and saves link of each file in database. also, I have a search page which I can search for those files and should be able to open them. firefox could not open the files and I changed the way of saving files to this method: $uploadDir = 'file:///C:/wamp/www/newweb/ExamPapers/';
previously, when I was not using file:/// firefox alerted an error in attempting to open. but now, it does not do any reaction and does not open.

in upload page I save the file with these codes:

$uploadDir = 'file:///C:/wamp/www/newweb/ExamPapers/';

if(isset($_POST['upload']))
{
$fileName = $_REQUEST[subject_name];
$tmpName = $_FILES['userfile']['tmp_name']; //path to the file
$fileSize = round((($_FILES['userfile']['size'])/1024/1024), 2);
$fileType = $_FILES['userfile']['type'];

// get the file extension first
$ext = ".pdf";

// make the file name
$uniqueName = $_REQUEST[subject_code] ."_". $_REQUEST[semester] ."_". $_REQUEST[year];

//the unique file name for the upload file
$filePath = $uploadDir . $uniqueName . $ext;

$result = move_uploaded_file($tmpName, $filePath);

if (!$result) {
echo "Erro uploading file";
exit;
}

if(!get_magic_quotes_gpc())
{
$fileName = addslashes($fileName);
$filePath = addslashes($filePath);
}

*************************************************************************
and in search page, I refer to them this way:

while ($row = mysql_fetch_assoc( $result ))
{
$sc = $row['Subject_code'];
$sn = $row['Subject_name'];
$dep = $row['Department'];
$sem = $row ['Semester'];
$y = $row['Academic_Year'];
$size = $row['file_size'];
$link = $row['file_path'];

print("<tr>");
print("<td>$sc</td>");
print("<td>$sn</td>");
print("<td>$dep</td>");
print("<td>$sem</td>");
print("<td>$y</td>");
print("<td>$size</td>");
print("<td><a href = \"$link\" target=\"_blank\"><img src=\"../Images/View.png\" alt=\"View exam paper\"></a></td>");
print("</tr>");
}

can anyone tell me whats the problem with opening the file?

Try backslashes

$uploadDir = 'C:\wamp\www\newweb\ExamPapers\';

backslash does not work to specify path of location in php. besides, I wanted to use file:/// method to be able to open it...
anyway thx for the try...

Do you see error messages in your server error log?

You have missed out hte part of the script in which you do the database insert - can I see that?

no, no errors.

actually, I've solved this problem with changing the path saved in database as this:
$urlPath = 'http://localhost/newweb/ExamPapers/'. $uniqueName . $ext;

now it works perfectly.
thanks for the reply.
