   <?php
 include("connect.php");
 session_start();

if(isset($_SESSION['ID']))  //Checking if they have the session cookie
{


$result = mysql_query("SELECT * FROM orders INNER JOIN register WHERE customer_id ='".$_SESSION["ID"]."' LIMIT 10");

echo "<table border='1'>
<tr>
<th>User ID</th>
<th>Username</th>
<th>Prices</th>
</tr>";

while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['customer_id'] . "</td>";
echo "<td>" . $row['Username'] . "</td>";
echo "<td>" . $row['total_price'] . "</td>";
echo "</tr>";
}
echo "</table>";

mysql_close($con);
}

else
{
    echo "<title>Error!</title>";
    //Doesn't have session cookie
    echo "YOU ARE NOT LOGGED IN!";
}
?>

</body>
</html>

connect.php

<?php
$hostname="localhost"; //local server name default localhost
$username="root";  //mysql username default is root.
$password="";       //blank if no password is set for mysql.
$database="register";  //database name which you created
$con=mysql_connect($hostname,$username,$password);
if(! $con)
{
die('Connection Failed'.mysql_error());
}

mysql_select_db($database,$con);
?>

with the code above , it show every data on the database.

echo "<td>" . $row['customer_id'] . "</td>";
echo "<td>" . $row['Username'] . "</td>";
echo "<td>" . $row['total_price'] . "</td>";

on the code above , ( customer_id, total_price data are from orders table, and Username are from register table )

I wanted that only show specific data based on session id only .
