Question

请帮我解决这个问题。我想仅在激活会话时访问页面内容，否则重定向用户首先激活会话。但是当我将用户重定向到会话页面时，它会卡住并且无法返回到内容页面。我是新来的，所以请帮我解决这个问题。

<?php 
session_start();
if(!isset($_SESSION['username'])){
		echo "cookie is not activated" ;
		header('Location: http://localhost/CC/Loginsession.php');
		die;
}
else {
?>
<!doctype html>
<html>
<head>
<title>Update in PHP</title>

</head>
<body>


<?php
		$servername="localhost";
		$username="root";
		$password="";
		$conn=mysql_connect($servername,$username,$password);
	 
	if(!$conn ) {
     		die('Could not connect: ' . mysql_error());
	}

		$sq1 = 'select * from biodata';
		mysql_select_db('firstdb');
		$display=mysql_query($sq1,$conn);

	if(!$display ) {
	
				die('Could not get data: ' . mysql_error());
				exit;
	}

	if (mysql_num_rows($display) == 0) {
				echo "No rows found, nothing to print so am exiting";
				exit;
	}

echo '<script>window.location="localhost/CC/Loginsession.php"</script>';
