How to do domain mapping in WP4.5 without plugin?

You can check out https://github.com/trendwerk/domains for a simple custom domain mapping sollution.

Hope this helps.

Go to Network Admin -> Sites -> Edit Site -> edit the site URL.

I’m having problems with this too.

“You can check out https://github.com/trendwerk/domains for a simple custom domain mapping sollution.”

It appears that solution is for subdirectory based Multisites. What about subdomain based Multisites?

“Go to Network Admin -> Sites -> Edit Site -> edit the site URL.”

It appears that solution simply performs domain forwarding from the Multisite subdomain site to another domain name. I thought the function of Domain Mapping was to substitue a registered domain name for a Multisite subdomain.

Thank you,

I apologize for jumping the gun. My previous post should be deleted.

I’ve deactivated sunrise.php and domain_mapping.php, removed the reference to sunrise from wp-config.php; and the result is, the domain mapping works as planned utilizing:

“Go to Network Admin -> Sites -> Edit Site -> edit the site URL.” as Ron indicated. So far I have not deleted the domain mapping tables created upon configuring the Domain Mapping plugin.

The problem now is, the URL to the subsite’s admin login redirects to the multisite’s register page. I secured all my subsite admin logins with an SSL wildcard certificate on the main domain and was able to configure the Domain Mapping plugin to use the subsite’s original URL with an encrypted login. How do I now secure the subsite admin logins? Should I open a ticket elsewhere?

Thank you,
Don

The redirect to the main site is happening either in your DNS or web server config.

Ron,

Thanks for the reply but it’s actually not a redirect that’s happening.

When I’m logged in as the Super Admin and roll over the domain’s dashboard link in the My Sites pulldown menu, the URL shown is https://the-registered-domain-name/wp-admin, not the original subdomain.

I did create an A record at the the registrar pointing the registered domain name to the dedicated IP address of the Multisite installation; however, without that tweak, the domain mapping wouldn’t work at all, correct?

Thank you,
Don

however, without that tweak, the domain mapping wouldn’t work at all, correct?

No, it won’t. That’s not a tweak though. You have to do that regardless of how you handle the domain inside your WP install.

Ron,

OK, “tweak” was a poor choice of words on my part and I apologize for clouding the issue.

However, the version 4.5 paradigm for domain mapping still isn’t working on my system. It does in fact map a registered domain name to the subdomain; but on the same token, prevents access to the original subdomain’s dashboard. As I indicated above, when I’m logged in as the Super Admin and point my mouse at the subdomain’s dashboard link in the My Sites pulldown menu, the URL shown is https://the-registered-domain-name/wp-admin, not https://the-subdomain/wp-admin. When I click on the link, I am taken to a WordPress Admin login page where I can’t login as either the Super Admin or the Site Admin because of a cookie issue I can’t resolve.

So… how does one successfully map a registered domain name to a Multisite subdomain without “shuttting down” the subdomain’s dashboard?

Thank you,
Don

Ron,

Thank you so much for sharing this, it’s outstanding!

For my multisite network I needed to add these to my wp-config.php because without them I couldn’t directly log in to my subsites:

define('ADMIN_COOKIE_PATH', '/');
define('COOKIE_DOMAIN', '');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');
