File listing Script and rediecting to a URL

[robjohn]

Hello all,
I am very new to PHP, basically have been looking into it for about a week. I currently have a file directory script that I would like to modify but I have not been able to find the information on what function I need to use.

The directory listing uses the following code to allow the user to download a file.

if($GET['download'] && $forcedownloads) {
$file = str_replace('/', '', $GET['download']);
$file = str_replace('..', '', $file);

if(file_exists($leadon . $file)) {
	header("Content-type: application/x-download");
	header("Content-Length: ".filesize($leadon . $file)); 
	header('Content-Disposition: attachment; filename="'.$file.'"');
	readfile($leadon . $file);
	die();
}

}

I would like to have the script redict the user to the same path within a predefined URL. For example if the file lives in /pics/photo.jpg, and the user chooses to click on the file displayed, I would like them rediected to http://192.168.1.1:8000/pics/photo.jpg.

I also see within the code the following which maybe the point at which I would "inject" the URL:

	$filename = $files[$i];
	if(strlen($filename)>43) {
		$filename = substr($files[$i], 0, 40) . '...';
	}

	$fileurl = $leadon . $files[$i];
	if($forcedownloads) {
		$fileurl = $_SESSION['PHP_SELF'] . '?dir=' . urlencode($leadon) . '&download=' . urlencode($files[$i]);
	}

I have looked at the header function however I am not if it is what I should be using based upon what I have read.

Thanks for the assistance in advanced.

I'm not shure this can be done in PHP but through .htaccess it should be possible with something like this:

RewriteEngine on
RewriteRule ^pics/([a-zA-Z0-9]+).jpg$ http://192.168.1.1:8000/pics/$1.jpg

Or something like that 🙂

Ryan,
Thanks for the reply. I did see many references to the Apache information, however I am trying to keep it in the code so it can be a portalable page for any PHP enabled server.

I did do a little more digging last night after my post and I belive if there is some way to append a :8000 to the $_SESSION[PHP_SERVER] I think that might do it as well. All though I might have wrong variable in place since it is at home.

Thanks
Rob
