PHP files included within functions.php don't work from admin area

Question

I've split my functions.php into multiple files using require_once, which works perfectly. However when I add admin functionality (extra panels) in one of the included files, it doesn't work? It's making me put the code in functions.php which I don't want to do.

This is the top of my functions.php

<?php
error_reporting(E_ALL);
ini_set('display_errors', True);

// Includes
require_once('includes/admin.php'); // Admin stuff

You'll have to check if you're in admin: if ( is_admin() ). If you're asking the oposite, then your're denying access. — kaiser

There is no condition for the included files, I've just tried adding if(is_admin()) but no luck. — Mythical Fish

In short: If you're questioning if ( is_admin() ) then the following stuff only triggers if you're on an admin page. So you maybe have something wrapped into such a statement (or the ! is_admin() opposite) and therefore your files aren't loading. — kaiser

There are no conditions for the included file, I have require_once('includes/admin.php'); at the top of my functions.php :) — Mythical Fish

Turn on all your DEBUG stuff including all php error stuff. — kaiser

The problem here is that you're not including yourtheme/includes/admin.php, you're actually including wp-admin/includes/admin.php, so pass a full path to the require statement rather than a relative one e.g.:

require(get_template_directory().'includes/admin.php');

And why did this work for public files? /wp-admin?

it's to do with the order that PHP looks for files, remember when you're in admin the point of entry is inside the wp-admin folder, whereas for frontend it's one folder up. I imagine if there was an includes/admin.php in the same folder as wp-config.php it would also fail for the same reason without the above fix
