Automatic blog creation using username (only users can register)?

I would like to automate blog creation using usernames.

** or even just blog default to username for url. Doesn’t really matter about the rest.

Is there a way to do this?

Can someone help me figure this out?

    Hey Paul,

    I hope you’re well today and thank you for your question!

    I can see that you’ve asked similar question recently here:

    As my colleague @vinod Dalvi said, this would require a custom coding which is way beyond the scope of this support forum. I think you may want to post a question at our “Jobs & Pros” job board here (please note that there’s no WPMU DEV staff there!):

    That being said, this code might be of help:

    The idea here is to automatically create blog by giving only a Site Title. Taking this as a base it should be possible to use username instead of site title and to hook this code to registration process.

    I hope this helps!

    Hello @paul

    I hope you are well today.

    Please go to Network Admin > Settings > Registration Settings > Allow new registrations > And select “User accounts may be registered.”.

    Then use the following code:

    add_action( 'user_register', 'create_new_blog', 10, 1 );
    function create_new_blog( $user_id ) {
    $user_info = get_userdata( $user_id );
    wpmu_create_blog( $user_info->user_login, '/'.$user_info->user_login.'/', $user_info->user_login, $user_id , array( 'public' => 1 ) );

    You can add those codes in your functions.php in the theme, if you think your theme won’t be changed. Otherwise mu-plugins is the best solution. To use mu-plugins, go to /wp-content/ and find the folder with name ‘mu-plugins’. If there is no folder in that name, then create a folder, name it ‘mu-plugins’, create a file inside that, give any name you like and paste the code in there. You don’t need to activate that plugin. Mu-plugins means must use plugins, so it will be activated automatically always. If you use mu-plugins then add a php start tag at the beginning of the code.

    Hope it helps :slight_smile: Please feel free to ask more question if you have any.

    @adam Czajczyk

    Thank you all very much. It’s hard to ask questions on here because I want to be clever enough to do it all myself. But I am very grateful for all your hard work and knowledge.

    Thanks again for the support and solutions. I will definitely be continuing with WPMUDEV when it’s time to renew my subscription. You guys have been invaluable!

    I have not tested this yet, but I will do so very soon.

    It seems after activating AntiSplog the form has reverted back to asking for sitename and title. Is there a way to work around this? The plugin worked perfectly before!

    Now that I have the rename wp-signup.php running it has reverted to original.

    Please if you could assist with this, that would be perfect.

    Most Kindly,

    I think I may be mistaken. For clarification… This function automatically creates a blog site for my new registered users?

    Or is it only designed to implant the username and ask only for the site title?

    Reason I ask, I created a new user and the blog site was automatic. If this is what the function is for, then that is brilliant!

    Please clarify if possible.
