WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

I use WordPress Multisite... and BuddyPress installed on the main site on mysite.com

Practically I want users to be automatically redirected to the main site login page every time they try to login from any of the blogs/sites/subdomains.

*.mysite.com/login.php => mysite.com/login.php

Let me give some exemples:

site1.mysite.com/wp-login.php redirected to mysite.com/wp-login.php

site2.mysite.com/wp-login.php redirected to mysite.com/wp-login.php

xyzkw.mysite.com/wp-login.php redirected to mysite.com/wp-login.php

.......................

any future subdomain LOGIN PAGE - with no exceptions - will have to be redirected to mysite.com/wp-login.php

You could you do this with redirects through the root .htaccess file;

Something like this perhaps:

# Redirect to new login

<IfModule mod_rewrite.c>

# For security reasons, Option followsymlinks cannot be overridden.

# Options +FollowSymLinks

Options +SymLinksIfOwnerMatch

RewriteEngine on

RewriteCond %{HTTP_HOST} ^subdomain.mysite.com/login.php [OR]

RewriteCond %{HTTP_HOST} ^www.subdomain.mysite.com/login.php [NC]

RewriteRule ^(.*)$ http://www.my-main-site.com/login.php/$1 [L,R=301]

</IfModule>

# Redirect end

Or to redirect all sub-domains to the parent, you could try this as a "catch all":

RewriteCond %{HTTP_HOST} !^my-main-site\.com$ [NC]
RewriteRule ^(.*)$ http://my-main-site.com/$1 [L,R=301]

Or if you want to exclude some sub-domains you could do this:

RewriteCond %{HTTP_HOST} !^my-main-site\.com$ [NC]
RewriteCond %{HTTP_HOST} !^excluded-sub\.my-main-site\.com$ [NC]
RewriteRule ^(.*)$ http://my-main-site.com/$1 [L,R=301]

You'll have to have a play to get the login.php working. This link may help: http://www.scriptygoddess.com/archives/2007/06/13/redirect-a-subdomain-to-a-directory-using-htaccess/

Is this gonna redirect all my subdomains? I ask because this line looks strange: "RewriteCond %{HTTP_HOST} ^subdomain.mysite.com/login.php [OR]"! Maybe I din't make myself clear, I want all, like *.mysite.com redirect to... –  Nicusor Dumbrava Mar 8 '12 at 0:56
    
I edited my answer above to add the catch all, hope that does it for you –  Sol Mar 8 '12 at 4:49
    
Thank you I will test it, and get back to you, thanks :) –  Nicusor Dumbrava Mar 8 '12 at 16:18
    
I don't want all my subdomains to redirect to the mainsite, I just want all the login pages to redirect to my mainsite login page... [ *.mysite.com/login.php => mysite.com/login.php ] If you know WP has a mysite/wp-admin for every blog/site in a network/multisite installation... and I don't want to customize every login page for every blog, just the one in the mainsite :) ... your code doesn't work for me, I need to customize it when I'll understand .htaccess scripting. –  Nicusor Dumbrava Mar 17 '12 at 17:23
