    #-Link-Snipped-# - Two things -

    1. Is that the full error message? Is there any detail included after Undefined index:.. ?
    2. Possible for you to post the code so that experts here can dig deeper?

    1. Is that the full error message? Is there any detail included after Undefined index:.. ?
    2. Possible for you to post the code so that experts here can dig deeper?

    Actually,here's the full message-

    Notice: Undefined index: uname in C:\xampp\htdocs\project\login.php on line 5

    Notice: Undefined index: pwd in C:\xampp\htdocs\project\login.php on line 6

    and code-
    <?php
    session_start    ();
    include(    "connection.php");
    ob_start();
    $a=$_REQUEST['uname'];
    $b=$_REQUEST['pwd'];
    if(isset(    $_REQUEST['sub_login']))
    {
    $query="select * from register where uname='$a' and pwd='$b'";
    $queryexe=mysql_query($query);
    $count=mysql_num_rows($queryexe);
    $row=mysql_fetch_array($queryexe);
    $id=$row['user_id'];
    $_SESSION['user_id']=$id;
    if(    $count>0)
    {
    header("location:profile.php");
    }
    else
    {
    ?><script>alert("Invalid Username/Password");</script><?php
    }
    }
    ?>
    <script>
    function validation()
      {
      if(document.login.uname.value=="")
    {
    alert("Please Enter Your Username")
    document.login.uname.focus();
    return false;
    } 
    if(document.login.pwd.value=="")
    {
    alert("Please Enter Your Password")
    document.login.pwd.focus();
    return false;
    }
      }

    That's a bad coding art, you must check if there is any data in $_REQUEST or not assuming uname and pwd will always be present in data, if not then check isset($_REQUEST['uname'])

    if(!empty($_REQUEST)){
 
 
}

    Change the part:

    $a=@$_REQUEST['uname'];
    $b=@$_REQUEST['pwd'];
    It is a temporary fix only.

    I agree with goyal, never assume that the program would behave the way you think it will be.
    When a developer develops something, he/she performs unit testing without much of destructive cases(a happy flow), but ideally this is a bad and a wrong practice to assume. Always check for values, same applies when session variables are being stored or retrieved.
