[garydt]

	session_start();
$disc = $_GET['topic'];	
$logon = ($_SESSION['MM_Username']);

mysql_select_db($database_elvisdb, $elvisdb);
$query_Recordset6 = "SELECT * FROM discussions WHERE discnum='$disc'";
$Recordset6 = mysql_query($query_Recordset6, $elvisdb) or die(mysql_error());
$row_Recordset6 = mysql_fetch_assoc($Recordset6);
$top = $row_Recordset6['topic'];
$prv = $row_Recordset6['private'];
$u = $row_Recordset6['user'];
$u1 = $row_Recordset6['user1'];
$u2 = $row_Recordset6['user2'];
$u3 = $row_Recordset6['user3'];
$u4 = $row_Recordset6['user4'];
$u5 = $row_Recordset6['user5'];
$totalRows_Recordset6 = mysql_num_rows($Recordset6);

if ($prv=="Yes") {
if ($logon=='') {
header("Location: login.php");
}
if ($logon!='$u') {
header("Location: forum.php");
} else {
}
}  

 

I've made a forum where users can create private discussions where upto 5 other users are allowed in the discussions.

$logon is the current logged on user and $u is one of the allowed users.

If the allowed user is logged on and tries to view the private discussion it won't let them. It also doesn't let any user view the private discussion which doesn't makes sence.

What have i got wrong?

What do you meen by won't let them? What happens?

[garydt]

it doesn't open the discussion page, it just goes to forum.php  -

if ($logon!='$u') {
header("Location: forum.php");
} else {
}

Variables are not parsed within single quotes. Try...

 

if ($logon != $u) {
