Using Session to Pass Data from php to another page

Question

I know this has been asked many, many, many times; however, the various things I have seen and tried have not worked.

All I want to do is pass data from one page to the next, so I can use the user's email to do various Database things.

Here's my login.php file (abridged, only showing the login stuff) :

<?php
session_start();

ini_set("display_errors", "1");

$user_email = $_POST['user_email'];
$_SESSION['user_email'] = $user_email;

$password = $_POST['user_password'];

//DB stuff

if ($num_results == 1) {

header('Location: nextPage.html');
exit;
}

else {

echo "<p> Username or Password is incorrect! </p>";
}
?>

Here is my next page html file:

<?php
session_start();

ini_set("display_errors", "1");

$email = $_SESSION['user_email'];

echo $email;
?>


<html>
<head>
<title> next page </title>
</head>

<body>

You have logged in!
</body>
</html>

Whenever I try to echo the email it is blank, and when I test for it, it tells me that it is empty.

Any advice would be helpful, thanks so much!!

also its good practice to check if $_POST values are actually set before using. — Lawrence Cherone

The post values are set and getting checked, sorry I abridged the code, forgot to put that part in. @Tushar, is there any specific reason why the next page would need to be php instead of html? — Nolan Anderson

That worked (changing it to .php), thanks so much!!!! I would love to know why, though :p — Nolan Anderson

The reason why you are having problems is that your header('Location: nextPage.html'); is pointing to an .html file.

Passing sessions from one page to another will only work under a PHP environment and should have been set as header('Location: nextPage.php');

However, .html files can run as PHP by using the following directives in .htaccess

AddType application/x-httpd-php .html

If you only plan on including the PHP on one page, it is better to setup this way:

<Files nextPage.html>
AddType application/x-httpd-php .html
</Files>
