## Description
Important: This plugin has a new maintainer. So the plugin will now be active developed
again, and it’s now part of [goINPUT](https://goinput.de).
Multiple Domain allows you having more than one domain in a single WordPress installation.
This plugin doesn’t support
more than one theme or advanced customizations for
each domain. It’s only intended to enable constant navigation under many domains.
For a more complex setup, there is [WordPress Multisite (MU)](https://codex.wordpress.org/Create_A_Network).
When there is more than one domain set in your host, all links and resources will
point to the default domain. This is
the default WordPress behavior. With Multiple
Domain installed and properly configured, it’ll update all link on the fly. This
way, the user navigation will be end-to-end under the same domain.
You can also set an optional base URL. If you want only a set of URL’s available
under a given domain, you can use this
restriction.
Additionally, a language can be set for each domain. The language will be used to
add `` tags with `hreflang`
attribute to document head. This is for SEO purposes.
## Installation
Follow the steps below to install the plugin:
1. Upload the plugin files to the `/wp-content/plugins/multiple-domain` directory,
or install the plugin through the
WordPress plugins screen directly.
2. Activate the plugin through the ‘Plugins’ screen in WordPress.
3. Use the Settings -> General screen to configure your additional domains.

de.
### Does this plugin set extra domains within my host?
No. You have to set additional domains, DNS, and everything else to use this plugin.
### Can I have a different theme/content/plugins for each domain?
Nope. If you want a complex set up like this, you may be interested in WordPress
Multisite. It’s delivered with every
WordPress installation since 3.0, you can
find more info here: https://codex.wordpress.org/Create_A_Network.
### There is a way to add domain based logic to my themes?
Absolutely. You can use the `MULTIPLE_DOMAIN_DOMAIN` and `MULTIPLE_DOMAIN_ORIGINAL_DOMAIN`
constants to get the current
and original domains. Just notice that since the value
of the first one is checked against plugin settings, it may not reflect the actual
domain in `HTTP_HOST` element from `$_SERVER` or user’s browser. They also may include
the host port when it’s different than 80 (default HTTP port) or 443 (default HTTPS
port).
**Notice**: in prior versions these constants were wrongly prefixed with `MULTPLE_`,
missing the “I”. The old constants
are now deprecated. They still available for
backcompat but will be removed in future releases.
### Can I create a custom access restriction logic for each domain?
Yes. You can use the `multiple_domain_redirect` action to do that. Please check
https://github.com/straube/multiple-domain/issues/2 for an example on how to do
that.
### Can I get the language associated with the current domain?
Yes. You can use the `MULTIPLE_DOMAIN_DOMAIN_LANG` constant to get the language
associated with the current domain. Keep
in mind the value in this constant doesn’t
necessarily reflect the actual user language or locale. This is just the language
set in the plugin config. Also notice the language may be `null`.
**Notice**: in prior versions these constants were wrongly prefixed with `MULTPLE_`,
missing the “I”. The old constants
are now deprecated. They still available for
backcompat but will be removed in future releases.
### Can I show the current domain in the content of posts or pages?
Yes. There is a shortcode available for that. Just add `[multiple_domain]` to the
post/page and it’ll be replaced by
the current domain when viewing the content.
You can write things like “Welcome to [multiple_domain]!”, which would be rendered
as “Welcome to mydomain.com!”.
### What domains should I add to the plugin setup?
Any domain you’re site is served from must be added to the plugin configuration.
Even `www` variations and the original
domain where your WordPress was installed
in must be added. You’ll probably see some unexpected output when accessing the
site from a non-mapped domain.
### Can I disable `hreflang` tags output even for the original domain?
Yes. You may notice that even if you don’t set a language for any domain, you still
get a default `hreflang` tag in
your page head. To disable this behavior, follow
the instructions from https://github.com/straube/multiple-domain/issues/51.
### I locked myself out, and what am I doing now?
Under certain circumstances, in the case of a wrong configuration, you may not be
able to log in to the admin area
and your page will be redirected. In this case,
there are two ways to solve this.
1. Delete the plugin directory `wp-content/plugins/multiple-domain`. You should be
able to do that from the hosting
panel, from an FTP client, or via SSH. The downside
of this technique is that it won’t be possible to install the plugin again since
the configuration will still be in the database.
2. Remove the plugin configuration from the database using the following SQL query`
DELETE FROM {YOUR-PREFIX}_options
WHERE option_name LIKE 'multiple-domain-%'
;(
Remember to replace the prefix from your own table name). This can be
done from
the hosting panel when PHPMyAdmin is available or using a MySQL client.

### [tailscale 100 IP works](https://wordpress.org/support/topic/tailscale-100-ip-works/)
[RaymondDay](https://profiles.wordpress.org/raymondday/) July 11, 2024
Wow this is super. I looked it up and installed a Plugins name “Multiple Domain”
and said “Add domain” and typed in the IP of tailscale the one that starts with
100 and went on my WordPress app on my cellphone and said add a site and typed that
100 IP /blog and it works! Turn off my Wi-Fi just to test and it still works That’s
grate just what I wanted. I can still get to it on my LAN PC too. Maybe some how
post this so it can help others.
### [Excellent plugin](https://wordpress.org/support/topic/excellent-plugin-9130/)
[Bence Szalai](https://profiles.wordpress.org/grapestain/) May 3, 2024
It works great in multiple installations I manage. The latest one runs WordPress
6.5.2, so don’t worry about the warning: This plugin hasn’t been tested with the
latest 3 major releases of WordPress. This plugin uses standard WP API and is very
stable despite the age. Great work!
### [Works great](https://wordpress.org/support/topic/works-great-8742/)
[AndreCarvalho](https://profiles.wordpress.org/andrecarvalho/) March 23, 2023
This is exactly what I was looking for, it allows you to have more than one domain
showing the exact same content and with a rewrite (not redirect). Has others have
pointed out, this is great for local development and then publishing in the production
env. Thank you to the authors for the great work.
### [Saving a lot of frustration](https://wordpress.org/support/topic/saving-a-lot-of-frustration/)
[tornevall](https://profiles.wordpress.org/tornevall/) December 22, 2022
Having a staging page separated from production, but in the end with same databases,
switching to that staging site without being redirected back to a production URL
is a total lifesaver!
### [Perfect solution for local development](https://wordpress.org/support/topic/perfect-solution-for-local-development/)
[tobiasroeder](https://profiles.wordpress.org/tobiasroeder/) March 17, 2022
This Plugin is a perfect solution when I’m developing on my local machine and want
to share the website on my local network without reinstalling with my local IP address.
Now I can simply use my custom local domain name and my local IP address and simply
share the website on my local network. Awesome plugin, highly recommended.
### [Great](https://wordpress.org/support/topic/great-13824/)
[BestRanger](https://profiles.wordpress.org/bestranger/) October 5, 2021
