    Hi! I almost finished the login system for my Rickrolla website. But, I keep having problems with the Cookies. This error keeps occuring

    Here's the code for login.php
    <?php
require "header.php";
?>
<body>
<?php
function login($errors=''){
if($errors){
print 'Correct the following errors...';
print '<li><ul>';
print implode('</li><li>',$errors);
print '</li></ul>';
}
print<<<_HTML_
<form method="POST" action="$_SERVER[PHP_SELF]">
Your Name:	<input type="text" name="name">
<br>
Your Password: <input type="password" name="password">
<br>
Done!: <input type="submit" value="done">
<input type="hidden" name="_submit_check" value="1">
</form>
_HTML_;
}

function retrieve(){
$errors= array();
mysql_connect("localhost", "admin", "password");
mysql_select_db("booo_db");
$user_name = $_POST['name'];
$password =$_POST['password'];
$query = "SELECT user_password FROM users WHERE user_name='{$user_name}'";
$result=mysql_query($query);
$row=mysql_fetch_assoc($result); 
if(!$password=$row['password']){
$errors[]="Wrong username or password";
}
}
if($_POST['_submit_check']){
	if($form_errors=retrieve()){
	login($form_errors);
	}else{
	doit();
	}
}

if(!$_POST['_submit_check']){
login();
}
?>
<?php
require "footer.php";
?>
    PHP:
    Here's the code for header.php
    <?php
function doit(){
setcookie($row['user_name']);
print "You're login Mr.".$_COOKIE['user_name'];
}
?>
<html>
<head>
<title>Rickroller.com</title>
<link rel="stylesheet" type="text/css" href="style.css" />
</head>
<div id="Header">
	<div id="Nav" align="right">
		<a href="register.php">Register Here!</a>/ 
		<?php
		if(empty($me)){
		print '<a href="login.php">Login Here!</a>/';
		}else{
		print '<a href="user.php?user='.$me.'">My Homepage </a>/';
		}
		?>
		</div>
</div>

    Do u notice you actually output something before u call the doit() function.

    functions like setcookie() , and header() wouldn't allow any output before it (including blank spaces).

    replace your header.php (your most top file) with this to your header.php

    
<?php
ob_start();
function doit(){
setcookie($row['user_name']);
print "You're login Mr.".$_COOKIE['user_name'];
}
?>
