Login system

[Hylian]

I'm working on a login system for my site and I have it connecting to a MySQL database to authenticate the user. I have got that to work, yet I want it to set a cookie with the Name of the user and the Password of the user. The login page (login.php) has the username and password field for the users to fil out and if all enetered data matches the database, they are directed to loginsuccessful.php. I want to pass the information from the login.php page into the loginsuccess.php where a cookie script will set the variables username, password, and GET the UserID from the MySQL database. I just don't know how to set the cookie variable to hold three values. Could someone help me out?

login.php

// ^ above is confidetial code to connect to database
<form name="form1" method="POST" action="<?php echo $KT_LoginAction?>">
<input type="hidden" name="setuser" value="set">
  <div align="center"> 
    <table width="50%" border="1">
      <tr> 
        <td>User Name:</td>
        <td> <input name="User" type="text" id="User"> </td>
      </tr>
      <tr> 
        <td>Password:</td>
        <td> <input name="Password" type="text" id="Password"></td>
      </tr>
      <tr> 
        <td>&nbsp;</td>
        <td> <input type="submit" name="Submit" value="Submit"></td>
      </tr>
      <tr> 
        <td>&nbsp;</td>
        <td>&nbsp;</td>
      </tr>
    </table>
  </div>
</form>

loginsuccessful.php

 
//header
<?php

if (isset($_COOKIE["user_cookie"])) : 
switch ($_COOKIE["user_cookie"]) { 
case "set": 
$UserName = "$User";
$UserPass = "$Password";
break;
case "del": 
$UserName = "00";
$UserPass = "00";
break;
}
endif;

if (isset($setuser)) { 
setcookie("user_cookie","$UserID",mktime(0,0,1,08,15,2020),"/","www.hylian.anime-honor.com","0");
$UserName = "$User";
$UserPass = "$Password";
}
?>
//header

if ((!$username) || (!$password)) {
$username = $HTTP_SESSION_VARS["username"];
$password = $HTTP_SESSION_VARS["password"];
if ((!$username) || (!$password)) {
header("Location: http://65.26.138.33/index.php");
exit;
}
} else {
setcookie("username", $username, time()+2592000, "/", "65.26.138.33", 0);
setcookie("password", $password, time()+2592000, "/", "65.26.138.33", 0);
setcookie("authorized", "yes", time()+2592000, "/", "65.26.138.33", 0);
}

Personal Database information goes here

$result = mysql_query($sql, $connection) or die(mysql_error());

while($row = mysql_fetch_array($result)) {
$userid = $row['userid'];
$realm = $row['realm'];
}
setcookie("userid", $userid, time()+2592000, "/", "65.26.138.33", 0);
setcookie("realm", $realm, time()+2592000, "/", "65.26.138.33", 0);

$num = mysql_numrows($result);

if($num == 0) {
header("Location: http://65.26.138.33");
exit;
} else {
header("Location: http://65.26.138.33/members.php");
exit;
