When I run your code through my formatter, it looks like this:
<?php
mysql_connect("username", "password") or die(mysql_error());
mysql_select_db("db") or die(mysql_error());
//Checks cookie
if (isset($_COOKIE['ID_my_site'])) {
$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 != $info['password']) {
}
//if the login form is submitted
if (isset($_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 ($check2 == 0) {
die('That user does not exist in our database. <a href=add.php>Click Here to Register</a>');
}
while ($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.');
} else {
// if login is ok then we add a cookie
$_POST['username'] = stripslashes($_POST['username']);
$hour = time() + 3500;
setcookie(ID_my_site, $_POST['username'], $hour);
setcookie(Key_my_site, $_POST['pass'], $hour);
}
?>
<form action="<?php
echo $_SERVER['PHP_SELF'] ?>" method="post">
<table border="0">
<tr><td colspan=2><h1>Login</h1></td></tr>
<tr><td>Username:</td><td>
<input type="text" name="username" maxlength="40">

<tr><td>Password:</td><td>
<input type="password" name="pass" maxlength="50">

Hopefully from the indention you can figure out what's wrong (since I don't feel like trying to figure out exactly what logic you want).
