WordPress multisite domain mapping for the modern era.
Mercator is a domain mapping plugin for the New World. Using new features included with WordPress 3.9 and later, Mercator builds on the new multisite features and abilities to improve your world.
Stop using outdated practices, and start making sense.
Mercator requires WordPress 3.9 or newer for the new sunrise processes. Mercator also requires PHP 5.3+ due to the use of namespaced code.
Mercator must be loaded during sunrise.
We recommend dropping Mercator's directory into your mu-plugins
directory,
then creating a wp-content/sunrise.php
file with the following:
<?php
require WPMU_PLUGIN_DIR . '/mercator/mercator.php';
Additionally, in order for sunrise.php
to be loaded, you must add the following to your wp-config.php
:
define('SUNRISE', true);
This plugin is a complete replacement for WPMU Domain Mapping. The database structure is fully compatible.
Note that if you have Domain Mapping code in your sunrise, you should remove this and replace it with the recommended sunrise code above. Mercator hooks in to WordPress' internal site mapping code rather than replacing it, unlike Domain Mapping.
Mercator is licensed under the GPLv2 or later.
Mercator is written and maintained by @rmccue.
Mercator builds on concepts from WPMU Domain Mapping, written by Donncha O'Caoimh, Ron Rennick, and contributors.
Mercator relies on WordPress core, building on core functionality added in WP27003. Thanks to all involved in the overhaul, including Andrew Nacin and Jeremy Felt.
