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>
<?php
//LOAD INBOX MESSAGES
// pagination references:

$conn = mysql_connect('localhost','root','');
mysql_select_db('squprime',$conn);
$sql = "SELECT * FROM messages WHERE to_stu_username='".$_SESSION['username']."' ORDER BY date" or die(mysql_error());
//Create a PS_Pagination object
$pager = new PS_Pagination($conn,$sql,10,10);
$result = $pager->paginate();
?>

<!-- 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.
