Pass data from PHP to HTML

Question

Edit: Thank you for your help and time. I will change all my extension to .php as recommended and check the link that was shared :)!

I'm a beginner at coding and I have been stuck for a few days on a problem. So, I have coded a html page with a login form. Once the user click the button login, the username and password will be checked in a php file and then if it's correct, the user will be redirected to the successfully login html page. I get redirected to the success login html page but I just can't pass the user data, I have tried to add a .htaccess so I can try to echo the session username but it doesn't display the username.

How do I pass the data of the user session to the new html page? I have been looking on forum and online but didn't really find an answer. If you guys have advices or suggestions, it would be helpful as I'm a beginner. Thanks for your answers and help!

Here is the php part of what should happen if the user successfully login:

check.php

if(password_verify($password, $row["password"]) {  
    $_SESSION['loggedin'] = true;
    $_SESSION['username'] = $username;
    header( 'Location: http://successfullogin.html' );
}

The successfullogin.html code:

<?php 
session_start()
?>
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Profile</title>
 <meta name="viewport" content="width=device-width, initial-scale=1, 
shrink-to-fit=no">
<link rel="stylesheet" href="/css/style.css">
<script src="/js/script.js"></script>
 </head>
  <body>

  <div>

<h1>Sucess login </h1>
<?php
echo $_SESSION[‘username’];

?>

</div>

</body>

</html>

Everything doesn't work apparently. Do you have `session_start()` at the very top of your pages, before anything else? — GetSet, Aug 23 '20 at 18:34
@GetSet I have a session_start() at the very beginning of my page. I mean it redirect me to the header location when the username and password are correct. Sorry for my wordings. — user14144054, Aug 23 '20 at 18:37
Does the redirect page have the session_start(). Can you show that code? — GetSet, Aug 23 '20 at 18:38
@GetSet It's very simple as I first wanted to be able to get the data before adding anything else — user14144054, Aug 23 '20 at 19:00
You need `session_start()` first thing on all pages (just once though, on the top-most page, not every included page) that deal with both setting and using the session so whereever the `if(password_verify($password, $row["password"])` line is, that also requires `session_start()`. — Rasclatt, Aug 23 '20 at 19:00
Answer by @Aggestor Mhl may be applicable to your problem if your redirect file is not extension'd in `.php`. — GetSet, Aug 23 '20 at 19:47
@Rasclatt Thanks I will keep it in mind and put it at the top of my php file each time! — user14144054, Aug 23 '20 at 21:59

You can't run PHP in .html files cause the server don't recognize that extension as a valid one. To tell your server to understand html files as valid check this topic below

How do I add PHP code/file to HTML(.html) files?

Or change your successfullogin.html to successfullogin.php

Makes sense. OP says that it does get redirected. Good point to mention that the redirect file should also extension in `.php`. – GetSet Aug 23 '20 at 19:46
Ok thanks, this was one of the option I was thinking about. I just wanted to see if there was another way to pass the data while keeping the .html extension. I saw some people mention ajax too, but I saw most example were on php file extension too. – user14144054 Aug 23 '20 at 19:58
Ajax needs a PHP file which will talk to your server, so you just make an ajax call using Javascript to display ajax response in an HTML file – Aggestor Aug 23 '20 at 20:01

Basically ajax helps to get data from server without reloading the whole document, I'll recommend you to learn it if you never learn it before – Aggestor Aug 23 '20 at 20:03
@AggestorMhl Ok thanks for recommendation! I think I should start from that too :)! – user14144054 Aug 23 '20 at 21:49
