[An updated version of this code is now available!]

I had always been missing a system like this in Wordpress and Joomla (to install plug ins). This codes snippet lets to transfer files directly from one server to another without having to do a pesky job of downloading them to your computer first and uploading it afterwards.

Here is the code for the PHP part:
Please scroll down for the AJAX implementation of this code snippet.

define ("ERROR_MSG", "Error: Please enter a valid URL!");
define ("SUCCESS_MSG", "Success: The file %s had been transfered to the server.");

define ("CONFIG_BoxedFolder", "UploadedFiles/");
function transferfile($url){
echo "Please Wait!";
$filepath=CONFIG_BoxedFolder.basename($url);
// return copy($url, $filepath); use this if your PHP supports it (Works from PHP v4.3).
$ret = false;
$fp = fopen($url, "rb");
if ($fp){
$fp_Dest = fopen($filepath, "wb");
if ($fp_Dest){
$BinaryData = '';
while (!feof($fp)) {
$BinaryData .= fread($fp, 8192);
}
$ret = fwrite($fp_Dest, $BinaryData);
fclose($fp_Dest);
}
fclose($fp);
}
return $ret;
}
if (isset($_GET['url'])){
$filepath = $_GET['url'];
if (transferfile($filepath)){
//Exit the program with our success message
exit(str_replace("%s", basename($filepath), SUCCESS_MSG));
}
}

else echo ERROR_MSG;
?>

The above code works fine except when the files are too large. If it takes too much time for PHP to copy the file, it simply halts transferring file due to browser’s connection timeout.

To tackle this problem I’ve created a full AJAX implemented version of this code, based on the ‘PHP file manager (AJAX demo)’ I posted earlier.

The above code is just for concept, its better to get the AJAX version of this code snippet.

Furture Plans:

Add a progress bar to indicate file transferring progress.
