  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
  {
  ?>}
  }
  ?>

  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.
