Cannot modify header information - headers already sent

[w3rthlesspe0n]

So I have a login box in my header, which worked when i hosted it locally, but now everytime i try to login i get

 

Cannot modify header information - headers already sent (output started at /home/content/06/7711706/html/index.php:15) in /home/content/06/7711706/html/includes/header.php on line 102 and 103 Which is the setcookie bit, not sure what i'm doing wrong though.

 

Any idea what i'm doing wrong?

 

Thanks

 

 

<?php include('variables/variables.php'); ?>


<div id="header">
<?php include('includes/flash.php'); ?>

  <?php

mysql_connect("XXXXXXXXX", "XXXXXXX", "XXXXXX") or die(mysql_error()); 

mysql_select_db("XXXXXXX") or die(mysql_error()); 

if(isset($_COOKIE['test']))

{ 
	$username = $_COOKIE['test']; 

	$pass = $_COOKIE['pass'];

	 	$check = mysql_query("SELECT * FROM customers WHERE username = '$username'")or die(mysql_error());

	while($info = mysql_fetch_array( $check )) 	

		{

		if ($pass != $info['password']) 

			{

			 			}
		else

			{

			header("Location: members.php");

			}

		}

}


if (isset($_POST['submit'])) { 


	if(!$_POST['username'] | !$_POST['pass']) {

		die('You did not fill in a required field.');

	}

	$check = mysql_query("SELECT * FROM customers WHERE username = '".$_POST['username']."'")or die(mysql_error());

$check2 = mysql_num_rows($check);

if ($check2 == 0) {

		die('That user does not exist in our database. <a href=reg.php>Click Here to Register</a>');

				}

while($info = mysql_fetch_array( $check )) 	

{

$_POST['pass'] = stripslashes($_POST['pass']);

	$info['password'] = stripslashes($info['password']);


	if ($_POST['pass'] != $info['password']) {

		die('Incorrect password, please try again.');

	}
else 

{ 


$_POST['username'] = stripslashes($_POST['username']);
$hour = time() + 3600;

setcookie(test, $_POST['username'], $hour);
setcookie(pass, $_POST['pass'], $hour);

header("Location: members.php");

} 

} 

} 

else

Did you read the sticky topic: HEADER ERRORS - READ HERE BEFORE POSTING?

[w3rthlesspe0n]

Yep, none of that worked :/

 

Well either that or i'm not understanding it properly

[Pikachu2000]

Did you misunderstand the part about not being able to output anything to the browser before sending a header?

 

<?php include('variables/variables.php'); ?>


<div id="header">  // <---- THIS IS OUTPUT
<?php include('includes/flash.php'); ?>

Hi,

I may be wrong but i dont think you can have header(); after <div id="header">. I have read up on it before, i cant remember if its whether something has been displayed in browser so you can physically see it, it or when you view the source and something has been output before the header.

Yeah what Pikachu2000 says, i knew it was one of the 2 lol.
