Hello,

I am trying to create a messaging system inter-user within the same website.

1 message_id int(4)
2 from_stu_username varchar(30)
3 date datetime
4 messages varchar(200)
5 to_stu_username varchar(30)

admin/messages.php

    //Hapus berita // undefined index: mode



    if (!empty($_REQUEST['message_id']))
        {
        $message_id = $_REQUEST['message_id'];
        $result = mysql_query("DELETE FROM messages WHERE message_id =".$message_id) or die(mysql_error());

        $confirmation = !$result ? "Gagal menghapus data." : "Data telah terhapus."; 
        }


?>
<div align="center">
    <div style="width:700px;text-align:left;padding-top:5px;">
        <?php  if (isset($confirmation)) { echo $confirmation; } ?>  
        <form method="get" action="<?php $_SERVER['PHP_SELF'] ?>">

                                    <br/>

                        <button type="button" onClick="parent.location='add_message.php'">Compose</button><br><br>

        </form>


    </div>
</div>
  </center>
</div> 

                <!-- End Insert -->  

The only problem is with the delete system, if I delete a row then, another row within another user is also being deleted. Is there any other way to delete messages but only for the user.

Each user should have a post id for a message. Much like here on daniweb. Then you just delete all messages for that user on that thread.

I think post_id just like message_id, if you delete one message_id, then not only the message from the sender outbox is being deleted but also the message from the receiver inbox is being deleted.
