Installation & Setup

The composer file is set up to assume you want to install this package with other WordPress must-use vendor plugins. These setup instructions assume that all your composer-required must-use plugins are stored in a main /mu-plugins/vendor directory and that you are using a loader.php file to require them. You may need to adjust the configuration if your environment is different.

After installation and setup, an option to override the default basic auth setting (detected by environment) will exist on the General settings page. This option allows you to disable the basic auth on dev or staging environments from the WordPress application. By default the option will detect the environment and be checked if no setting is saved.

Step 1

Install the plugin via composer.

composer require humanmade/php-basic-auth

Step 2

Add 'vendor/php-basic-auth/plugin.php' to the array of must-use plugins in the loader.php file in the root of your /mu-plugins directory. Make sure it is the first item in the array.

The final result should look something like this:

<?php
/**
 * Plugin Name: HM MU Plugin Loader
 * Description: Loads the MU plugins required to run the site
 * Author: Human Made Limited
 * Author URI: http://hmn.md/
 * Version: 1.0
 *
 * @package HM
 */

if ( defined( 'WP_INSTALLING' ) && WP_INSTALLING ) {
	return;
}

// Plugins to be loaded for any site.
$global_mu_plugins = [
	'vendor/php-basic-auth/plugin.php',
	/* ... other must-use plugins here ... */
];

Step 3

Define a HM_BASIC_AUTH_USER and HM_BASIC_AUTH_PW wherever constants are defined in your project. This could be your main wp-config.php file or a separate .config/constants.php file.

Note: While not required, it's best to check that you are in a development environment before defining HM_BASIC_AUTH_USER and HM_BASIC_AUTH_PW to prevent the constant declarations from being defined in all environments. This adds an additional layer of protection against basic auth accidentally being loaded in production.

You may also want to disable basic authentication on local environments.

Your constant declarations should look something like this:

// Check if we're in a dev environment but not local.
if (
	// HM_DEV is defined and true.
	( defined( 'HM_DEV' ) && HM_DEV ) &&
	// HM_LOCAL_DEV is either undefined or false.
	( ! defined( 'HM_LOCAL_DEV' ) || defined( 'HM_LOCAL_DEV' ) && ! HM_LOCAL_DEV )
) {
	// Set Basic Auth user and password for dev environments.
	define( 'HM_BASIC_AUTH_USER', 'myusername' );
	define( 'HM_BASIC_AUTH_PW', 'mypassword' );
}

Step 4 (optional)

If you do not want to load the basic authentication check on local environments, and you have not already defined HM_LOCAL_DEV in your wp-config-local.php file, you should do that now.

/**
 * Set the environment to local dev.
 */
defined( 'HM_LOCAL_DEV' ) or define( 'HM_LOCAL_DEV', true );

You should also add these lines to your wp-config-local.sample.php.

Created by Human Made to force authentication to view development and staging environments while still allowing those environments to be viewed in a logged-out state.
