@scvinodkumar

 

I've place it here..

<?php

session_start();
ob_start();

include('../../resources/config.php');
include($config["paths"]["resources"] . 'opendb.php');
include($config["paths"]["resources"] . '_library/login.php');

$email = mysql_real_escape_string($_POST['email']);
$password = mysql_real_escape_string($_POST['password']);

authenticateUser ($email, $password); 

include($config["paths"]["resources"] . 'closedb.php');

?>

 

Now everything seems to work just fine? but i would like to understand what this peace of code is doing? any help there?

 

[scvinodkumar]

u need to call that function at the very beginning of the file, i mean at the very first line of the page.

You need to fix your code so that there is no output being sent before the header() statement. The error message states where the output is occurring at. You likely have something in your opendb.php file after the closing ?> tag.
