[Resolved] PHP Sessions and Header Problems

[dan2158]

session_start();
header("Cache-control: private");
if(isset($_POST['username'])){
	if(isset($_POST['password'])){	
		$username=$_POST['username'];
		$password=$_POST['password'];
			if($username="test"){
				if($password="test"){
					session_register('username');
					session_register('password');
					session_register('access_granted');
					$_SESSION['access_granted']="YES";
					$_SESSION['username']=$username;
					$_SESSION['password']=$username;
					header("Location: http://www.myronline.com/phptests/sestest2.php");
					exit;
				}else{
				$loginerror="Incorect Password";
				}
			}else{
			$loginerror="Unknown Username";
			}
	}else{
	$loginerror="Please Enter Login Information:";
	}
}else{
$loginerror="Please Enter Login Information:";
}
?>

This Code gives me these warnings.

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at C:\Program Files\Apache Group\Apache2\htdocs\phptests\sestest.php:4) in C:\Program Files\Apache Group\Apache2\htdocs\phptests\sestest.php on line 5

Can anyone tell me what I'm doing wrong. I'd greatly appreciates any help.

Thanks,
Dan

I think it's because you are calling session_start() before the cookie stuff. I realize, looking at your code, that this is something that needs to be done. However, within my experience, anything relating to cookies has to be done first, before anything else is sent (such as starting a session, or echoing something out to a page).

I had figured out not too long ago. I had my php code in the head of an html file. I put the code before eveythign including the html and it worked fine. Thanks for your help its much appreciated.
