Calling s2Member from external PHP

[replaysMike]

Hey all,

Is it possible to call into s2Member's API functions or internal functions from an external PHP file?

I've got some files that I am unable to protect using the file_download_key/s2member_file_download method as they are SWF files that load other SWF files, and I can't control the absolute path from which they load. So they can't reside inside the s2member-files directory.

My plan was to simply create a wrapper PHP file which is already being passed a generated file_download_key, but I have no way to validate that key as I'm not sure which PHP files to include to access the library.

Help? Thanks!

Mike

I'd probably start by searching something like http://www.google.com/search?q=use+word ... on+outside

hey thanks! That's exactly what I was looking for. Now I just need to figure out how to validate that key in the s2Member code... for others here's what I did:

Code: Select all

   require_once("../../wp-load.php");
   get_header();
   echo "Custom PHP page outside of wordpress.<br/><br/>";
   echo "<p>".s2member_file_download_key('mydownloadfile.zip')."</p>";
   get_footer();

ok I got it, here's how you validate a download key from outside of wordpress:

Code: Select all

   require_once("/wordpress_root_dir/wp-load.php");
   $download_key = $_GET["s2member_file_download_key"];

   if($download_key){
      echo "<p>Download key: $download_key</p>";
      
      $verified_key = c_ws_plugin__s2member_files::file_download_key ('Module1.html');
      $file_download_key_is_valid = $download_key === $verified_key;
      
      echo "<p>Verified key: $verified_key</p>";
   }else{
      // No download key provided
      $file_download_key_is_valid = false;
   }   

   if($file_download_key_is_valid)
      echo "Valid";
   else
      echo "Invalid";


In my case I hardcoded the filename as 'Module1.html', and only pass in the key which is also generated based on the same filename. Seems to work well.

Thanks Christian

Thank you for sharing that! I'm sure others will find it very helpful when they try to do something similar.
