Is this possible?

[ewe]

I was similarly irritated by reply not grabbing a title and I accidentally stumbled upon this. I felt the need to change one thing, though - a devious and clever user could theoretically go through message IDs and read things not meant for them.

PHP Code:

$message = new PrivateMessage; 
// CHANGES START HERE

$title = "(no subject)"; // this way it'll never be blank
if($mysidia->input->get("id")){ // if there's an get value
    $where = trim($mysidia->input->get("id")); // trim the value
     if (!ctype_digit($where)) { // if its not numeric only
        $user = $where; // create a message to this user
    } else if (ctype_digit($where)){ // if it IS numeric only then it's a reply, so pull data        
        $oldMessage = new PrivateMessage($where); 
        //my little paranoid change is here: 
        if($mysidia->user->username == $oldMessage->fromuser) {     
          $js = "<script>$('.content h2').text('Reply To Message');</script>"; // optional
          $user = $oldMessage->fromuser;     
          $title = "RE: ".$oldMessage->messagetitle;    
          $msg = "› {$user} wrote: ".$oldMessage->messagetext;
        }
    }
}

// CHANGES END HERE
$editor = $message->getEditor();
