i have this function.

 

function GetFile() 
{ 
$filename = $_GET['currFile'];
$filename = str_replace("/adam","",$filename);
$filename = "http://www.adamplowman.co.uk".$filename;
echo $filename;


// required for IE, otherwise Content-disposition is ignored
if(ini_get('zlib.output_compression'))
  ini_set('zlib.output_compression', 'Off');

// addition by Jorg Weske
$file_extension = strtolower(substr(strrchr($filename,"."),1));

if( $filename == "" ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: download file NOT SPECIFIED. USE force-download.php?file=filepath</body></html>";
  exit;
} elseif ( ! file_exists( $filename ) ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: File not found. USE force-download.php?file=filepath</body></html>";
  exit;
};
switch( $file_extension )
{
  case "pdf": $ctype="application/pdf"; break;
  case "exe": $ctype="application/octet-stream"; break;
  case "zip": $ctype="application/zip"; break;
  case "doc": $ctype="application/msword"; break;
  case "xls": $ctype="application/vnd.ms-excel"; break;
  case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
  case "gif": $ctype="image/gif"; break;
  case "png": $ctype="image/png"; break;
  case "jpeg":
  case "jpg": $ctype="image/jpg"; break;
  default: $ctype="application/force-download";
}
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers 
header("Content-Type: $ctype");
// change, added quotes to allow spaces in filenames, by Rajkumar Singh
header("Content-Disposition: attachment; filename=\"".basename($filename)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize($filename));
readfile("$filename");
exit();
}

 

I alwasy get the error message File not found. USE force-download.php? I copy and past the link manually and i get the file displayed. Any one got any ideas.

 

I got the script from http://elouai.com/force-download.php

$filename = $_GET['currFile'];
$filename = str_replace("/adam","",$filename);
$filename = "http://www.adamplowman.co.uk".$filename;
echo $filename;

 

did you add these lines the script uses file_exists and readfile they can be used only on a local system not to get from http protocol

<?php
if( $filename == "" ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: download file NOT SPECIFIED. USE force-download.php?file=filepath</body></html>";
  exit;
} elseif ( ! file_exists( $filename ) ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: File not found. USE force-download.php?file=filepath</body></html>";
  exit;
};
?>

 

The error is because the file path wasn't given; so you either just went to www.mysite.com/force-download.php - therefore none specified.

right i have changed my script to

 

$filename = $_GET['currFile'];
$filename= $_SERVER['DOCUMENT_ROOT'].$filename;
echo $filename;

 

$filename no looks like

 

/homepages/12/d214897219/htdocs/adam/ftp/adam/cycling/images/header_01.jpg

 

But i am still getting the same error

well i am trying to build a simple ftp script. You navigate throught the direcorties and when you click on a file the url becomes Comand = getfile. This calls upon my function.

 

Heres the script below.

 

<?php
error_reporting(E_ALL);
$command = ""; 

if(isset($_GET["command"])) 
$command = $_GET["command"]; 
else 
$command = "listFiles"; 
switch($command) 
{ 
case "listFiles": 
ShowFiles(); 
break; 
case "getFile": 
GetFile(); 
break; 
case "putFile": 
PutFile(); 
break; 
case "renameFile": 
RenameFile(); 
break; 
case "deleteFile": 
DeleteFile(); 
break; 
default: 
ShowFiles(); 
} 

function DoConn() 
{ 
//server info
$ftpServer = "87.106.169.32"; 
$ftpUser = "u46180240"; 
$ftpPass = "CusWsc.5"; 

//connect and check login details
$c = @ftp_connect($ftpServer); 
$l = @ftp_login($c, $ftpUser, $ftpPass); 

if(!$c) 
die("A connection to $ftpServer couldn't be established"); 
else if(!$l) 
die("Your login credentials were rejected"); 
else 
return $c; 
} 

//show home directory
function ShowFiles() 
{ 
$conn = DoConn(); 
$currDir = ""; 

// Get the name of the current directory if home one is clicked
if(isset($_GET["currDir"])) 
$currDir = $_GET["currDir"]; 
else 
$currDir = ftp_pwd($conn); 

// Retrieve a list of files and directories 

$fList = @ftp_nlist($conn, $currDir); 

// We will work out the parent directory 
$parentDir = strrev($currDir); 
$parentDir = ereg_replace("^[a-zA-Z0-9\-]*/", "", $parentDir); 
$parentDir = strrev($parentDir); 
?>
<a href='ftp1.php?command=listFiles&currDir=<?php echo $parentDir; ?>'> </a> 
<br> 
<?php
//loop thrugh array of files and folders 
for($i = 0; $i < sizeof($fList); $i++) 
{ 
// We will remove the parent directory (if any) 
// from the name of the file that gets displayed 
$trimFile = ereg_replace("^$currDir", "", $fList[$i]); 

// Remove any forward slash at front of name 
$trimFile = ereg_replace("^/", "", $trimFile); 

if(@ftp_chdir($conn, $fList[$i])) 
{ 
@ftp_cdup($conn); 
?> 
<a href='ftp1.php?command=listFiles&currDir=<?php echo $fList[$i]; ?>'> 
<?php echo $trimFile; ?> 
</a> 
<br> 
<?php 
} 
else 
{ 
?> 
<a href='ftp1.php?command=getFile&currFile=<?php echo $fList[$i]; ?>&currDir=<?php echo $currDir; ?>'> 
<?php echo $trimFile; ?> 
</a> 
<br> 
<?php 
} 
} 
} 



function GetFile() 
{ 
$filename = $_GET['currFile'];
$filename= $_SERVER['DOCUMENT_ROOT'].$filename;
echo $filename;


// required for IE, otherwise Content-disposition is ignored
if(ini_get('zlib.output_compression'))
  ini_set('zlib.output_compression', 'Off');

// addition by Jorg Weske
$file_extension = strtolower(substr(strrchr($filename,"."),1));

if( $filename == "" ) 
{
  echo "<html><title>eLouai's Download Script</title><body>ERROR: download file NOT SPECIFIED. USE force-download.php?file=filepath</body></html>";
