Before we get started, i know some of the HTML is incorrect, this is just a test, but still no excuse for bad coding.

 

I have a problem with the login code... it was working fine, but i don't know what i have changed to make it not work...

It displays the following errors when i try to login:

 

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp2\htdocs\gaming\index.php:3) in C:\xampp2\htdocs\gaming\index.php on line 70

 

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp2\htdocs\gaming\index.php:3) in C:\xampp2\htdocs\gaming\index.php on line 71

 

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp2\htdocs\gaming\index.php:3) in C:\xampp2\htdocs\gaming\index.php on line 74

 

and i have had a error on line 24 of this file.

 

(i have marked the lines below)

 

 

 

This is the index.php file:

 

<html>
<head>
<style type="text/css">
body { background-color:orange } 
</style>
</head>

<body>
<?php 
// Connects to your Database 
mysql_connect("localhost", "root", "******") or die(mysql_error()); 
mysql_select_db("users") or die(mysql_error()); 

//Checks if there is a login cookie
if(isset($_COOKIE['ID_my_site']))

//if there is, it logs you in and directes you to the members page
{ 
$username = $_COOKIE['ID_my_site']; 
$pass = $_COOKIE['Key_my_site'];
$check = mysql_query("SELECT * FROM users WHERE username = '$username'")or die(mysql_error());
while($info = mysql_fetch_array( $check )) 
{
if ($pass != $info['password'])  //line 24
{
}
else
{
header("Location: home.php");

}
}
}

//if the login form is submitted
if (isset($_POST['submit'])) { // if form has been submitted

// makes sure they filled it in
if(!$_POST['username'] | !$_POST['pass']) {
die('You did not fill in a required field.');
}
// checks it against the database

if (!get_magic_quotes_gpc()) {
$_POST['email'] = addslashes($_POST['email']);
}
$check = mysql_query("SELECT * FROM users WHERE username = '".$_POST['username']."'")or die(mysql_error());

//Gives error if user dosen't exist
$check2 = mysql_num_rows($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']);
$_POST['pass'] = md5($_POST['pass']);

//gives error if the password is wrong
if ($_POST['pass'] != $info['password']) {
die('Incorrect password, please try again. <a href="java script:history.go(-1)">Go Back</a>');
}
else 
{ 

// if login is ok then we add a cookie 
$_POST['username'] = stripslashes($_POST['username']); 
$hour = time() + 3600; 
setcookie(ID_my_site, $_POST['username'], $hour);   //line 70
setcookie(Key_my_site, $_POST['pass'], $hour);  //line 71

//then redirect them to the members area 
header("Location: home.php");   //line 74
} 
} 
} 
else 
{ 

// if they are not logged in 
?>
