Hi all!, I have been installed successfuly freichat in my site and everything works as spected, but i want to deactivate the chat history saving in db. I dont want to register any conversation. I try modifying arg.php but the chat history still saving in bd. What can I do?

But if you completely disable chathistory , then the messages wont be
persistent while surfing on your website .

I mean everytime you load any page all your messages would be deleted
since the chathistory is not saved .
Do you really want that ?

Not exactly. I would like to have a chat history persisted in session, but i dont want that my dba can read all the messages in the chat. The people of the site dont trust in the chat system because they have afraid that someone else can read they messages. And the fact is that is happening. So i need some way to encrypt o do something for avoid that effect and demonstrate that anyone else can read they messages! understand me? (My english isn't as effective like i want)

Well, I started to modified the code to encrypt the message before they were inserting in DB and decrypt them whem they are selecting from de DB.

I change the function post_mess in server/freichat.php:

if ($_POST['message_type'] == 'normal' || $_POST['message_type'] == 1) {
                $chatroom_mesg_time = $_POST['chatroom_mesg_time'];
		$encrypted_mesg = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $message, MCRYPT_MODE_CBC, md5(md5($key))));
                $insert_mesg_query->execute(array($frm_id, $usr_name, $to, $to_name, $encrypted_mesg, $time, $message_type, '-1'));
            } else {
                //$chatroom_mesg_time = $time;
                $chatroom_mesg_time = $_POST['chatroom_mesg_time'];
		$encrypted_mesg = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, md5($key), $message, MCRYPT_MODE_CBC, md5(md5($key))));
                $insert_mesg_query->execute(array($frm_id, $usr_name, $room_id, $room_id, $encrypted_mesg, $time, $message_type, $room_id));
            }

find the function named as get_messages().
it returns an array of messages, just loop through the messages and decrypt them.

Ok, I added this to the function:

foreach($result as $row){
$row[5] = rtrim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, md5($key), base64_decode($row[5]), MCRYPT_MODE_CBC, md5(md5($key))), "\0");
}

But nothing happens!

Any ideas?

it should have worked.
try

$row['message'] instead of $row[5];

Well, I made it works! But now, when I refresh the page all sending message are show encrypted. I suppose that is because i must to do the same in another method, but which? I am so newbie with PHP!! hahaha!

Another thing, I am think in delete all messages sent between two user when the user close it session. I could see that the session is managed in database, so I suppose that the event of closing the session is handled in some place. Where is that?

If someone else is interested in that feature I could send the code with the new features. Obviously, those new features must be configure-ables.

Regards!
