<?php

$Username = $_POST['uname']; 
$Userid = $_POST['password']; 

// validating field values 

if($Role == "Select Role" || strlen($Username)<=0 || strlen($Userid)<=0) 
{ 
$counter = 1; 

echo "<center><font color=red><h3>"."Please, Provide values for all the fields"."</h3></font></center>"; 

exit; 
} 

$dbconnect = mysql_connect('localhost','root',''); 

if (!$dbconnect) 

    { 
    die ('could not connect:'.mysql_error()); 
    } 
$selectdb = mysql_select_db('UGI', $dbconnect); 

$query = "select EmployeeLoginType, EmployeeUserName, EmployeePassword from EmployeeCredentials where EmployeeLoginType='".$_POST['urole']."' and EmployeeUserName='".$_POST['uname']."' and EmployeePassword='".$_POST['password']."'"; 

$dbquary = mysql_query($query, $dbconnect); 

if (!$dbquary) 
    {

        $name = $rowfetch[1]; 
        $password = $rowfetch[2]; 
     } 
     if (strcasecmp($role, "Manager") === 0 && $name === "Bello" && $Userid === "smile2me") 
     { 
         header('Location:PeopleManagement.php');
