	include("Connection.php");
	include("ValidateStaffMessage.php");
	
	
	//getting values
	$ticketID = $_GET['id'];


	
	//select ticket with that id and referred staff email
	$sql_sel = "
SELECT * 
  FROM ticket 
 WHERE referedstaff2 LIKE '%$id%' 
    OR referedstaff1 LIKE '%$id%' 
    OR referedstaff3 LIKE '%$id%' 
    OR referedstaff4 LIKE '%$id%' 
   AND ticketid = '$ticketID'
 ";

	
	$query_sel = mysqli_query($connection, $sql_sel) or die ("Error in Display Ticket Sql." .mysqli_error($connection));
	
	if($query_sel)
	{
		echo "<h3 class=ta__center> Ticket Details: $ticketID </h3>";
	    echo "<div class=ta__left><a href=ReferTicket.php><img src=css/images/back.png></a></div><p>&nbsp;</p>";
