[closed] From Subdirectories to Subdomains, how to change WPMU after the MU install (10 posts)

    I changed my site from EXAMPLE.COM/USER to USER.EXAMPLE.COM in my WordPress MU install... Perfect for (very) small networks – not so good for large networks.

    How it works

    Many WordPress Network Administrators are familiar with the following:

    Addresses of Sites in your Network

    The primary information in this section involves the decision to use sub-domains or sub-directories for your sites. This means each additional site in your network will be created as a new virtual sub-domain or sub-directory. Please choose whether you would like sites in your WordPress network to use sub-domains or sub-directories. You cannot change this later.

    YOU CAN CHANGE IT!

    This is a quick tutorial for for medium to advanced WordPress Network (MultiUser) administrators.

    Problem: I installed the WordPress Network (WordPress MU) with user SubDirectories instead of SubDomains. Now, I want to change it. My host provider allows wildcard subdomains (http://*.example.com) so how do I fix this?

    Solution: After looking online at the wordpress.org forums – like here and here – I stopped at this post, Adam Wulf’s, Changing WordPress Mu from Subdomains to Subdirectories. Then it hit me.

    First, I created wildcard subdomain (as I said before, my host provider allows wildcard domains and documentation how to enable it). Next, I went to my ‘wp-config.php” and changed following line from:

    define( 'SUBDOMAIN_INSTALL', false);

    To this line:

    define( 'SUBDOMAIN_INSTALL', true);

    Then (for larger networks, this is not the best solution), I went to Network Admin > Sites page. I noticed that the values for Domain have reset to the default domain. I clicked on Edit, under the Domain value.

    For each site, I changed the Domain field from the default example.com site to the new site.example.com site (I used the value in the Path field, making sure I kept the “/” symble in the the Path field).

    I tested the WordPress site and everything is in working order. This was an issue I was able to correct rather quickly after initial install, so as I said before, larger networks would not benefit from this solution. If you have done this, and have some comments, please let me know how it went for you.

  2. I actually post how to do this all the time, but recommend not using the sub-blogs or doing this after you have established sub blogs.

    Funnily enough, I had a post on draft for a long time with how to do this and finally scheduled it for next Tuesday.

    i didn't know where else to post this jem...i've been working on WP for a long time but only have posted here a few times. i've been thinking of being a bit more active in the community :)

    i agree not to use sub-directory blogs. if your host provider allows wildcard domains, then go wild!

  4. i agree not to use sub-directory blogs.

    Actually, I said to not use the sub-blogs you created in one format after switching to the other format - unless you wanted to change the URLs.

    Some people in stall one format only to discover it's not working right (host doesn't have wildcards & they didn't check first, rewrite rules refuse to work for subfolder blogs..) and that's one big reason they may need to switch.

    When you have established sub-sites in any format, and then switch, you *will* get a nasty drop in SE.

    Hi,
    This didn't work for me. However, the line "define( 'SUBDOMAIN_INSTALL', false);" was not already in the config file. We're running 3.1. Any ideas?
    Thanks

    I followed the instructions here to create the network. From Sub-Dir to Sub-Dom is another deal.

    the line "define( 'SUBDOMAIN_INSTALL', false);" was not already in the config file.

    I believe you have to add them from your Network Admin Dashboard. Go to your Dashboard, go to Network Admin > Settings > Network Setup. There's a code you have to copy and paste into your wp-config.php file and another code for your .htaccess file.

    Hope this helps

    I appreciate know that I can change from subdirectory to subdomain. However, some items in your description are leaving me puzzled.

    "First, I created wildcard subdomain...”

    Did you mean subdomain(s)? Either way, what do you mean? I understand the concept of wildcard subdomains, but I have MU with one site as the main site (I stupidly set it up initially with subdirectories): mainsite.com and 5 “underneath” it; mainsite.com/1 - 5. I want to domain map and the setup using subdirectories doesn’t work. SO... do I set up a wildcard sub on each of the underlings? Or, just for the main site?

    What do you mean by this: (I used the value in the Path field, making sure I kept the “/” symble in the the Path field)? Do I leave the path alone with what was there originally?

    I hope you will see this soon as I have already mucked some things up.

  8. bodyworkmentor - Please make your OWN post.

    If you set up your site for subfolders, you can still map domains. They work just fine.

    I don’t understand what you mean by making my OWN post. I’m trying to follow the instructions for the tutorial above and I have questions regarding THAT tutorial.

    And, btw, they don’t work fine which is why I’m pursuing changing to subdomains.

  10. Make your own new thread here in the forums.

    If you have a subFOLDER setup then you do not need the wildcard subdomains.
