i put session_start() at the beginning of the code with no white spaces before.
validate.php looks like this:
<?php
session_start();
$user_name = $_POST['user_name'];
$password = $_POST['password'];
include("conn.php");
$query = "SELECT * FROM login WHERE user_name='$user_name' AND password='$password'";
$result = mysql_query($query, $connection) or die('error making query');
$affected_rows = mysql_num_rows($result);
if($affected_rows == 1) {
$valid = true;
}
else {
$valid = false;
}
?>
