$f_login = $q_login->fetch_array();

- Check your config.php it may includes localhost configs.
- Use
issetinstead ofISSET - You may need to add
<form action="login.php" method="POST">in your html code.

before
session_start();
add
session_name('someYourName');
So it will look like:
<?php
session_name('someYourName');
session_start();
Use same name in all files you want use same session. In your way you have different sessions for each php file.
On login.php
echo 'success';
session_start();
So if you want with "echo" you should do it like this:
session_name('someYourName');
session_start();
echo 'success';
You can't send any content before session start - best practice is to start session on beginning of page.
