Using X-Sendfile for downloads

[fx_keith]

Hey, I'm trying to bypass the self-hosted file downloads to pass it off to X-Sendfile on my server. I've had it working in older versions of s2member by hacking it into the plugin, but I obviously want to do this through an action hook instead.

Looking at classes/files-in.inc.php it looks like files are downloaded towards the end of 'c_ws_plugin__s2member_files_in::check_file_download_access', but I'm not seeing something I can plug into without clobbering all the file checking.

Ideally, I'd like to replace all the file headers in line #331

Code: Select all

else /* Else, ``if ($serving)`` , use local storage option (default).*/

with an X-Sendfile header like:

Code: Select all

header("X-Sendfile: $file_path");

Any suggestions on accomplishing that?

I would suggest using this Hook:
ws_plugin__s2member_during_file_download_access
viewtopic.php?f=40&t=13012&src_doc_v=111206#src_doc_line_274

Something like this perhaps.

Code: Select all

<?php
add_action ("ws_plugin__s2member_during_file_download_access", "my_s2_file_server");
function my_s2_file_server ($vars = array ())
    {
        if ($vars["serving"])
            {
                // Send file headers, and exit script execution.
                print_r($vars); // For debugging.
                exit ();
            }
    }
?>

Excellent. Thanks again Jason.
Note to anyone else doing this, the filepath in this example would simply be $vars['file'];

Thanks for the tip, fx_keith!

FYI - the headers are super simple. Mine look something like this.

Code: Select all

$file = $vars['file'];
$filename = basename($file);
$length = filesize($file);
header("USING_XSENDFILE: TRUE"); //for testing
header("X-Sendfile: $file");
header("Content-Length: $length");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"$filename\"");
