WP Plugin: Same level subdomains for multisites

This WordPress multisite plugin allows you to create subsites under the same subdomain depth as the main site.

Example use case

We needed to create subdomain multisite which uses only subdomains under *.client.com and nothing else. In this case client.com domain was simultaneously used elsewhere for non-WordPress site so that couldn't be the domain of the main site.

We created this plugin in order to use admin.client.com as the main site and site1.client.com, site2.client.com for the subsites respectively.

Installation

$ composer require devgeniem/wp-multisite-same-level-subdomains

Configuration

We recommend installing this plugin with composer or dropping it the plugin directory into your mu-plugins directory.

Then create a wp-content/sunrise.php file with the following:

<?php
// Default mu-plugins directory if you haven't set it
defined( 'WPMU_PLUGIN_DIR' ) or define( 'WPMU_PLUGIN_DIR', WP_CONTENT_DIR . '/mu-plugins' );

require WPMU_PLUGIN_DIR . '/wp-multisite-same-level-subdomains/wp-multisite-same-level-subdomains.php';

Additionally, in order for sunrise.php to be loaded, you must add the following to your wp-config.php:

define( 'SUNRISE', true );

Finally add your preferred domain into your wp-config.php:

define( 'MULTISITE_SAME_LEVEL_SUBDOMAINS', true );

Variables

This forces all created sites to be in the same subdomain as the main site:

define( 'MULTISITE_SAME_LEVEL_SUBDOMAINS', true );
