session error

fristi

I get this error in the following part of the code:



<html>
<head><title>News</title></head>
<body>

<?php
session_start();
if (isset($_SESSION['permission']) && $_SESSION['permission'] == true) {

if (!isset($_POST['submitform'])) {
?>

You're allowed and inside!

<?php
}
} else {

echo "You are not allowed to access this page<br><br>";

}
?>
</body>
</html>

Error:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at URL/news.php:5) in URL/news.php on line 6

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at URL/news.php:5) in URL/news.php on line 6

I use a login section with sessions.
What does this mean? Thanks for any help 🙂

try putting the php code even before <html>. If you are using cookie-based sessions, you must call session_start() before anything is outputted to the browser.

Thanks for the fast reply 🆒. It worked 🙂 I'll keep that in mind for the future!
