Prevent Direct File Access to functions.php

Snippets by IsItWP

Are you looking for a way to prevent users to access the functions.php file using a link? While there’s probably a plugin for this, we have created a quick code snippet that you can use to prevent direct file access to functions.php file in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

if (!empty($_SERVER['SCRIPT_FILENAME']) && 'functions.php' == basename($_SERVER['SCRIPT_FILENAME']))
{
die ('No access!');
}

Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly copy / paste code snippets in WordPress, so you don’t accidentally break your site.

    i suggest:

    defined(‘ABSPATH’) or die(‘nothing here.’);

    you can find ABSPATH in wp-config.php

    i suggest this:

    defined( ‘ABSPATH’ ) or die(‘i love you hacker.’);

    you can find ABSPATH in wp-config.php
    if the user load the wp environment correctly, ASBPATH should be defined or we kick them.

  4. i try it for my website, but it dont work and the website are down, it work after i change this line :
    die (‘He’s dead, Jim!’);
    todie (‘Hes dead, Jim!’);
    pls correct your code
    THANKS

    1. Opps sorry about that I fixed the error. Cheers Enjoey the snippet.

  5. This throws an error. The  “&&” should actually be “&&” for it to work.

    1. Oops. That didn’t work. The first && should be the HTML symbol for the ampersand- & amp; (without the space).
