I have written a very very very simple!! script in php. header redirection not working. 1- encoding : UTF-8 without BOM 2- with adding ob_start() the problem is countiueing. What is wrong in my code;
login.php:
<?php session_start();
require_once("funcs.php");
db_connection();
$username = $_POST['username'];
$password = $_POST['pwd'];
$submit = $_POST['login'];
if($submit){
if (!filled_out($_POST)) {
echo "please fill all fields";
}
else{
$query = "SELECT * FROM users WHERE username ='{$username}' AND password ='{$password}'";
$result = mysql_query($query);
if(mysql_num_rows($result) == 1){
$found_user = mysql_fetch_array($result);
$_SESSION['id'] = $found_user['id'];
$_SESSION['username'] = $found_user['username'];
$_SESSION['password'] = $found_user['password'];
setcookie(session_name(), '', time()+86400, '/');
header("Location: tst.php");
}
else{
echo "incorrect username or password";
}
}
}
?>

</p>
<p>
<input name="login" type="submit" id="login" value="Log in" />
</p>
</form>
</body>
</html>
<?php db_disconnect();?>
and tst.php:
<?php session_start();
require_once("funcs.php");
if (!isset($_SESSION['id'])){
header("Location : login.php");
}
?>

<td id="page">
<?php
echo "welcome"."". $_SESSION['username'];
?>

</html>
<?php db_disconnect();?>
wthit oppening tst.php directly, header() doesnot redirect to login.php
