Are you sure your connection is set up correctly in config.php?

I think so, because i just copy it from internet, and i change it according to my connection. Below the code for config.php

<?php
$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "";
$mysql_database = "trial";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) 
or die("Opps some thing went wrong");
mysql_select_db($mysql_database, $bd) or die("Opps some thing went wrong");
?>

Are you sure the query returns something? You should check that mysql_query() is returning true before continuing with the rest of your code. You should also check row count before fetching from it in case there are no records.

Please try it this php code
if your connection file is correct after you will use it

<?php
    include("connection.php");
    $Ocon = new connection();
    $Ocon->connect(); 
    if(isset($_REQUEST['btnlogin']))
    {
        $username = $_REQUEST['username'];
        $password = $_REQUEST['password'];
        $ssQuery = " SELECT * FROM admin WHERE username = '".$username."' AND password = '".$password."' ";
        $result = mysql_query($ssQuery); 
        $amInfo = $Ocon->fetch_data($result);
        if($username== $amInfo[0]['username'] AND $password==$amInfo[0]['password'])
        {
             $_SESSION['username']=$_POST['username'];
             header('Location: home.php') ;
            exit;
        }
        else
        {
            header( 'Location: index.php?msg=invalid username or password') ;
 
        }
    }
    ob_flush();
?>

//connection.php

$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "";
$mysql_database = "trial";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) 
or die("Opps some thing went wrong");
mysql_select_db($mysql_database, $bd) or die("Opps some thing went wrong");
