Basically i have a simple table (mbs_users) containing: 
基本上我有一个简单的表（mbs_users）包含：
Field Type Collation Attributes Null Default Extra Action
id int(5) No None AUTO_INCREMENT
username varchar(7) utf8_general_ci No None
password varchar(7) utf8_general_ci No None

</tr>
<tr>

</form>

</table>
Check login file 检查登录文件
<?php
$host="mysql.mywebsite.co.uk"; // Host name
$username="myusernamexx/ Mysql username
$password="password"; // Mysql password
$db_name="mbs_orderstatus"; // Database name
$tbl_name="mbs_users"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// username and password sent from form
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword");
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
?>
and then redirects to login_success.php 然后重定向到login_success.php
// Check if session is not registered , redirect back to main page.
// Put this code in first line of web page.
<?
session_start();
if(!session_is_registered(myusername)){
header("location:main_login.php");
}
?>
<html>
<body>
Login Successful
</body>
How do i get the field 'status' associated with the user that just logged in to show on this page? 如何获得与刚刚登录的用户相关联的“状态”字段以显示在此页面上？

You already have that information at the login page. 您已经在登录页面上获得了该信息。 At the login page you also set data into the session. 在登录页面上，您还可以将数据设置到会话中。 Why not set the data you need in the session? 为什么不设置会话中需要的数据？ That way you can use it at the other pages. 这样，您可以在其他页面上使用它。
So in login file: 因此在登录文件中：
$sql = "SELECT * FROM $tbl_name WHERE username = '$myusername' and password = '$mypassword'";
$result = mysql_query($sql);
$data = mysql_fetch_assoc($result);
$_SESSION['username'] = $data['username']
$_SESSION['status'] = $data['status']
And in login_success: 并在login_success中：
echo $_SESSION['status'];
