@NogDogOct 19.2010 — #The problem is that you are outputting text before your call to the login() function where the setcookie()'s are done. There can be no output -- including text or even white-space not within <?php...?> tags -- before any PHP function that sets HTTP headers, including setcookie(), session_start(), or header().
Probably the best solution is to reorganize the code so that anything that will set headers gets done before any output is generated, but as a work-around you could just do anob_start () at the very beginning of the file (again before any output of any sort).
[RESOLVED] Can’t seem to set cookies.
Ok so I’ve got the entire registration system working, and the forgotten password. but for some reason I can’t set the cookies. When I look at the source after getting “Warning: Cannot modify header information – headers already sent” I notice that “</head><body>” is showing up twice for an unknown reason. I’ll just post the important code (skipping all the different action possible).

<?
function login($user,$pass) {
$loginsql = “SELECT * FROM users WHERE email='”.$user.”‘”;
$loginresult = mysql_query($loginsql);
if ( mysql_num_rows($loginresult) == 0 ) {
return FALSE;
} else {
while ( $row = mysql_fetch_array( $loginresult ) ) {
if ( $user == $row[’email’] ) {
if ( $pass == $row[‘password’] ) {
$cookielength = 60*60*24*10;
setcookie(“Username”, $row[’email’], $cookielength);
setcookie(“login”, TRUE, $cookielength);
setcookie(“userid”, $row[‘idusers’], $cookielength);
return TRUE;
} else {
return FALSE;
}
} else {
return FALSE;
}
}
}
}
if ( isset ( $_GET[action] ) ) {
$action = $_GET[action];
} else {
$action = ‘form’;
}
if ( $action == ‘submit’ ) {
if ( login( $_POST[’email’], $_POST[‘pass’] ) ) {
$content = “<h2>Thanks for logging in.</h2>”;
} else {
$content = “<h2>Login Failed!</h2>”;
}
} elseif ( $action == ‘form’ ) {
….
}
?>
</head><body>
<?
echo $content;
?>
</body>
</html>
By two closed head open body statements in the source i mean the error page is:
[quote]
Warning: Cannot modify header information – headers already sent by (output started at /home/rdenni5/public_html/family/login.php:6) in /home/rdenni5/public_html/family/login.php on line 28

Thanks for logging in.
and the source of that is:

</head>
<body>
</head><body><h2>Login Failed!</h2>
</body>

Hope that is enough information for you. Sorry if its too much.
