Cake puts some characters which destroy .doc structure when
downloading. Here is an analogic function which works ok in plain php
script
function download_doc_file($id = null)
{
$this->autoRender = false;
$file = APP."rtf/".$id."/cv.doc";
$basename = basename($file);
$file_extension = strtolower(substr(strrchr($basename,"."),
1));
if (!file_exists($file))
{
print "ERROR: File not found. $basename";
exit;
}
else {
switch($file_extension)
{
case "PLS": $ctype="audio/x-scpls"; break;
case "pls": $ctype="audio/x-scpls"; break;
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;
default: $ctype="application/force-download";
}

readfile($file);
exit();
}
}
