How to call one folder into logged in file but when i connect my file through index.php?

Question

I'm working on a project for web application now my problem is I have login script which contain a views folder. Inside view folder I have three PHP files:

1. logged-in.php
2. not_logged_in.php
3. register.php

Apart my view folder I have one file index.php now have a look this picture click here.

Now when I run index.php file, it shows login main page if user is not logged in, otherwise will show up home page( which is logged-in.php inside view folder) if I run direct logged-in.php file directly then it will give an error so the whole process I must startup with index.php.

And here is code for index.php

<?php
// checking for minimum PHP version
if (version_compare(PHP_VERSION, '5.3.7', '<')) {
    exit("Sorry, Simple PHP Login does not run on a PHP version smaller than 5.3.7 !");
} else if (version_compare(PHP_VERSION, '5.5.0', '<')) {
    // if you are using PHP 5.3 or PHP 5.4 you have to include the password_api_compatibility_library.php
    // (this library adds the PHP 5.5 password hashing functions to older versions of PHP)
    require_once("libraries/password_compatibility_library.php");
}

// include the configs / constants for the database connection
require_once("config/db.php");

// load the login class
require_once("classes/Login.php");

// create a login object. when this object is created, it will do all login/logout stuff automatically
// so this single line handles the entire login process. in consequence, you can simply ...
$login = new Login();

// ... ask if we are logged in here:
if ($login->isUserLoggedIn() == true) {
    // the user is logged in. you can do whatever you want here.
    // for demonstration purposes, we simply show the "you are logged in" view.
    include("views/logged_in.php");

} else {
    // the user is not logged in. you can do whatever you want here.
    // for demonstration purposes, we simply show the "you are not logged in" view.
    include("views/not_logged_in.php");
}

Have a look at this pic, so the problem is I want to call my comment-folder inside logged-in.php so I use include('comment05/../.. .php'); inside my logged-in.php as you can see my pic.

But when I run this it shows the comment popup but when I click comment button it's giving error 404 file not found that mean it's recognizing the correct path. So I want to ask, do I need to change something into my index.php file or not? Because I guess I need to change something in their like using using include('comment05') and etc.

So can you help me with index.php file, what should I do in that case when I call a folder into logged-in.php file because the whole process is depend into index.php file? I mean my website is startup firstly with index.php.
