   While fixing the download function for the classes I noticed that in IE7 this header doesn't work:

   header('Content-Type: application/zip');

   actually this "general" header works fine:

   header('Content-Type: application/force-download');

   any idea why?

   <?php
   
   function dl_file($file){
   
       //First, see if the file exists
       if (!is_file($file)) { die("<b>404 File not found!</b>"); }
   
       //Gather relevent info about file
       $len = filesize($file);
       $filename = basename($file);
       $file_extension = strtolower(substr(strrchr($filename,"."),1));
   
       //This will set the Content-Type to the appropriate setting for the file
       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;
         case "mp3": $ctype="audio/mpeg"; break;
         case "wav": $ctype="audio/x-wav"; break;
         case "mpeg":
         case "mpg":
         case "mpe": $ctype="video/mpeg"; break;
         case "mov": $ctype="video/quicktime"; break;
         case "avi": $ctype="video/x-msvideo"; break;
   
         //The following are for extensions that shouldn't be downloaded (sensitive stuff, like php files)
         case "php":
         case "htm":
         case "html":
         case "txt": die("<b>Cannot be used for ". $file_extension ." files!</b>"); break;
   
         default: $ctype="application/force-download";
       }
   
       //Begin writing headers
       header("Pragma: public");
       header("Expires: 0");
       header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
       header("Cache-Control: public");
       header("Content-Description: File Transfer");
   
       //Use the switch-generated Content-Type
       header("Content-Type: $ctype");
   
       //Force the download
       $header="Content-Disposition: attachment; filename=".$filename.";";
       header($header );
       header("Content-Transfer-Encoding: binary");
       header("Content-Length: ".$len);
       @readfile($file);
       exit;
   }
   
   ?>

   This works in both IE and Firefox.

   Thanks for the example code, but try this content type

   case "zip": $ctype="application/zip"; break;

   in IE7 and you will see that it doesn't work (or at least with the dynamic zip file I have generated)

   don't get me wrong, the script I'm using is fine it's just the one header which is doing strange in IE7...

   OK,

   I think the problem is the class I'm using to create the zip files. It might be the same reason why the files can't be opened on a Mac system.

   Thanks!
