How to prevent direct reach ?

[Rommeo]

I have my template files and some functions in my server which are available for direct reach.

like ;

my "index.php" file includes "loginpage.php" form which is ok when I enter www.site.com/index.php

 

but also when I enter to www.site.com/loginpage.php it works and shows me just login page. So  this is what I dont want. How can I prevent to reach the files directly like this, I want them to work just for other pages of my website, not for directly seeing.

 

By the way can this problem also be solved by hosting settings or mod_rewrite ?

This can be solved by htaccess rules but here is one common way:

 

//index.php
define('SOMETHING', true);

//loginpage.php
defined('SOMETHING') or die();
   //or
defined('SOMETHING') or header('Location: index.php');
