Update 28th Feb, 2010: This plugin is updated, Please read more here http://buddydev.com/buddypress/limit-blogs-per-user-plugin-for-wpmu
Well,It’s a small post after a long time.This time ,I am back with a plugin for wordpress MU.There might have been the times ,when as a site admin of wpmu site, you wished to limit the number of blogs a user can register. My plugin, limitBlogsPU(limit blogs per user),solves this problem.So ,what it does .
- It adds an option to the options page when you are logged in as site admin of the wpmu site(or wpmu+buddyppress site),Look at the bottom of options page,and You will see a text box like this asking for number of blogs allowed per user.If you set it to zero(which is the default),It will not restrict the blog registration then.
- It works only,if you have allowed user registration,otherwise ,this becomes useless if the registration is disabled.
- When ,a logged in user clicks on register blog (or register another blog,It checks ,whether the current user has already reached the restricted number of blogs),if not then the registration form is shown,otherwise it returns none on filter “wpmu_active_signup” ,restricting the wpmu to not show registration form.
Who needs this plugin
- Any wpmu(wordpress Mu) site owner ,interested in limiting number of blogs registered per user
- Any Wpmu+buddypress(Social networking plugin) based social network owner,interested in restricting numer of blogs per user.
Where Can you Download
Currently You can download it from my blog here from official wordpress lugin repositoryhttp://downloads.wordpress.org/plugin/limit-blogs-per-user.1.0.zip .
Installation and setup:-
- Download the plugin from herehttp://downloads.wordpress.org/plugin/limit-blogs-per-user.1.0.zip
- Unzip the plugin and upload the file “limit-bogs-per-user.php“ to your mu-plugins folder.If you have never worked with wpmu before,please read my post WordPress Mu Plugins Installation, sitewide Plugins vs. per blog plugin .
- Now The plugin will be automatically activated,please login to the wordpress backend as Site Administrator(site owner)
- Go to SiteAdmin-> Options page as show below
Now look at the bottom of options page, you will find something like this 
There you will find ,a value 0 initially.Now you may set it to any number.The number indicates,the allowed number of blogs per user. I hope ,It will certainly help some of you.
Looking forward to your response. Brajesh

After trying the plugin it seems that no mather how many blogs I permit, an already registrered user cant create a new blog. If a user, who has no blog but just a username, tries to create blog number 1 he/she gets the ‘Blog creation is closed’-message.
Setting the number at the options-tab to 10 or 100 doesnt make a difference. Deleting the plugin-file makes it all work again.
@Kenneth
Can you point me to your website/blog.I checked again,and found no issues.There should not be any problem with it.I am counting the number of blogs of user using
get_blogs_of_user($logged_user_id),So I don’t think,It is causing any problem,If you can point me to your site,may be I can test.Thanks
Brajesh
Thanks, sir..
I’ll try this plugin
This plugin helps out a lot, however the admins should be not be limited to the number set. I’m sure many would agree that this needs to be adjusted.
Side Note: It appears you have a decent handle on writing plugins like this. You should also make a plugin for buddypress that limits the number of groups allowed.
@dgodfather
I agree with you ,will add the functionality in next release,and thanks for the suggestion,will certainly think about it -:)
i am using wordpress.org the 2.7.1 version and i can not find the option to limit all authors to 1 blog post.
so after looking at it, does this plugin allow me to set all “authors” with only 1 post limit, and once they 1 post limit is reached the Add New link on the dashboard is gone?
Thank You SOOOO MUCH!
Any update on not restricting site admins?
hi Ray,thanks for the message.Just next week,I will be releasing the next version,i am going to accommodate all the suggestions then.
Thanks
Brajesh
There is a problem actually. When user first registers through /register page it seems to work fine when the user signs up for a new blog. If he does not sign up for a blog and decides to sign up later, he will not be allowed to signup later.
The same problem exists when used with facebook connect plugin. They automatically login using fb-connect and don’t get the chance to sign up for a blog later.
It should be fixed and also as mentioned before admin should be allowed get unlimited no. blogs.
here is the problem with ur plugin.. if a user decides to register with out creating a blog, he gets assigned as a subscriber to the main sites blog.. well if you only want users to have 1 blog then he cant make one for himself… and if you change the value to 2, then he can make a blog but when he does it remove the main blog subscription and then lets him make another blog of his own..
hi MadLyfe
Thanks for pointing the issue.Yeh, you are right about the limitations.The adding to main blog and creating independent blogs are the features handled by wpmu,This plugin simply restricts on number of blogs ,the user is associated with.I will correct it in next release(waiting for wpmu 2.8.3),so It checks for the ownership of blog,not Just the associated blogs.
Thanks
Brajesh
can you add a feature to it so it adds a link on the “my blogs” section to create a their blog or another blog depending on the limit set? also the ability to set it so it auto creates the blog as their user name if the limit of blogs is set to one?
Thank you wery much for this plugin…
It’s not as good as it could have been due to the problem with subcriber accounts and one blog setting, but i’m looking forward to the update…
Regards..
Hans
@madLyfe & @Hans
Thanks for your comments and suggestions.Currently I am a little busy with the work,please wait for a few weeks and we will have an update
Thanks
Brajesh

I have to hard-code the pages limit..
thanks
Thanks for pointing jing,I need to test it.I will be providing an update after 8th september if it does not work.
Thanks
Brajesh
Any update yet on this plugin? Would love to see this plugin through.
Just tested, it works fine on WPMU-2.8.5.2.
Cheers!
If you change to this, admin and other bug will be fixed. Thank for the effort!
/**** Check, whether blog registration is allowed,and how many blogs per logged in user is allowed ****/
function tiw_check_current_users_blog ($active_signup)
{
if ( !is_user_logged_in() )
return $active_signup; // if the user is not logged in, do not change the site policies
//otherwise...
$number_of_blogs_per_user = tiw_num_allowed_blogs (); // find
if (0 == $number_of_blogs_per_user) {
return $active_signup;
}
global $current_user;
$blogs = get_blogs_of_user($current_user->ID); // get all blogs of user
//if number of allowed blog is greater than 0 and current user owns less number of blogs */
if ( ($number_of_blogs_per_user>0) && (count($blogs)<$number_of_blogs_per_user) ) {
return $active_signup;
} else {
return "none";
}
}
/**** How many blogs are allowed per user ****/
function tiw_num_allowed_blogs ()
{
$num_allowed_blog = get_site_option ("tiw_allowed_blogs_per_user"); // find how many blogs are allowed
if ( (!isset($num_allowed_blog)) || is_site_admin() ) {
$num_allowed_blog = 0;
}
return $num_allowed_blog; // return the number of allowed blogs
}
I was able to get this working well with this code at line 16:
function tiw_check_current_users_blog($active_signup)
{
if( !is_user_logged_in() || is_site_admin())
return $active_signup;//if the user is not logged in,do not change the site policies
//otherwise…
global $current_user, $wpdb;
$blogs=get_blogs_of_user($current_user->ID);//get all blogs of user
foreach($blogs as $key => $blog){
$cap_key = $wpdb->base_prefix . $blog->userblog_id . ‘_capabilities’;
if ( $blog->userblog_id == 1 || (is_array($current_user->$cap_key) && in_array(‘subscriber’, $current_user->$cap_key)) )
unset($blogs[$key]);
}
$number_of_blogs_per_user=tiw_num_allowed_blogs();//find
//if number of allowed blog is greater than 0 and current user owns less number of blogs */
if($number_of_blogs_per_user>0 && count($blogs)<$number_of_blogs_per_user)
return $active_signup;
else
return "none";
}
err… That actually doesn’t work right. The line:
needs to be changed to:
if ( $blog->userblog_id == 1 || (is_array($current_user->$cap_key) && !in_array(‘administrator’, $current_user->$cap_key)) )
This code excludes the main blog from the count an any blogs where the user is not an admin.
@deuts
) on the new update of plugin 
Thanks for visiting.There will be an update available by 9th Nov.
@Steph ,@Brand and Gingles
Thanks for your improvements.I have to test the updated version and I will quote you both(if your solution worked best
Thanks for all the suggestions and code snippets.
Hi,
I would please like to ask if this plug-in should work with the standard wordpress installation? (not MU). I am currently using wordpress 2.8.5. I am quite new to wordpress and I don’t use it frequently.
Also, after installing it with the wp version that I have, I can’t seem to find the input fields whihc would allow me to set the limit of posts for certain users.
Thank you very much for any help you may provide and more power to you!
hi Kin
This is for wordpress Mu(Multi user) and Buddypress Based site.It does not work with standard wordpress.
Oh. that is unfortunate. Anyway, thanks for the clarification. Cheers!
Thanks for the update. Looks like you missed adding:
global $wpdb; in the tiw_check_current_users_blog function.
Thanks again!
Thanks Steph for pointing the bug again.
thanks for all your help
Though There seems to be some other issues too.I have just reverted the stable tag to 1.0 and now Hopefully tomorrow will have a fully working plugin
I am already using this plugin on my blog and it works just fine. Great idea and nice work
Hei… really nice plugin here! Thanks!
Hi Brajesh,
Great Plugin. Will this work with wordpress mu 2.8.6 and buddypress 1.1.3?
Yes, It will work, but there is a glitch as pointed above, if you set the number of blogs to 1, it will not allow a subscriber to create a new blog.
I am looking forward to update this plugin after 15th feb to fix that 1 blog issue with subscriber.
Thanks
Brajesh
