allowing header() anywhere???

how do you allow using header() anywhere in your program? i made a program for a friend, and he's getting 'headers already sent' warnings.

yes, before any output is sent; or redesign your scripts so that they don't send output before headers.

yeah either or

(I use ob_start() a lot in my template system though, to capture output for later usage

)

Here is the script that causes errors. Is it because <html><body> is above the script???

PHP Code:


<html>
<body>
<?php
include("lib/config.php");
include("lib/db_connect.php");
include("lib/chk_ip.php");
if(isset($_POST['do_login'])) {
 $username = $_POST['username'];
 $password = md5($_POST['password']); 
 $query = "SELECT * FROM users WHERE username = '$username' AND password = '$password' AND permissions = '1' LIMIT 1";
 $result = mysql_query($query);
 if(mysql_num_rows($result) != 1) {
  header("location:login.php?error=Invalid");
 } else {
  setcookie("admin",1,time()+(60*30));
  setcookie("auth",$username,time()+(60*30));
  header("location:admin.php");
 }
}
?>
