I need to set some defaults for my multisite sites as they are created but It's not quite working. I have this in the install.php file in /wp-content:

function wporg_wpmu_new_blog( $blog_id, $user_id, $domain, $path, $site_id, $meta ) {
    update_blog_option( $blog_id, 'upload_url_path', 'http://mycdn.net/newsite' );
    update_blog_option( $blog_id, 'upload_path', '/home/www/myfiles/newsite' );
    update_blog_option( $blog_id, 'blog_public', '0' );


    // Remove the default post & page
    wp_delete_post(1, true);
    wp_delete_post(2, true);

    // Remove the first comment
    wp_delete_comment( 1, true );

add_action( 'wpmu_new_blog', 'wporg_wpmu_new_blog', 10, 6 );

Am I missing anything?

  • what part is not "quite working"? – yivi Dec 27 '16 at 22:34
  • None of it. I forgot to mention this code is in my index.php file in the wp-content folder. (updated question) – dcp3450 Dec 27 '16 at 22:35
  • In your question you say you have it in "install.php", in wp-content – yivi Dec 27 '16 at 22:36
  • I just updated it for anyone else who comes across the question – dcp3450 Dec 27 '16 at 22:38

install.php is only run during installation, it wont be run during new site creation.

You'd need to put that code in a mu-plugin to have any chance of running.

(I guess it could also exist in a network-activated plugin, but I'm not 100% sure of that)

Add the following before your code, and put your file in wp-content/mu-plugins:

Plugin Name: Yourmultisite options
Description: Foobar
Version: 1.0.0
Author: You
Author URI: http://www.examplecom
  • mu-plugins don't run any activation hooks. I placed the code for that in the directory and it didn't have any effect either. – dcp3450 Dec 27 '16 at 22:55
  • Did you create a plugin file in mu-plugins? Does it appear on the list of 'must use' plugins? – yivi Dec 27 '16 at 22:59
  • mu-plugins don't run "activation" hooks, but the action you want to hook onto, it's not an activation hook. – yivi Dec 27 '16 at 23:00
  • Ah, ok. I created the mu-plugins folder set permissions to 755 and loaded a php file in there with the above script but nothing changes when I view the site's settings. – dcp3450 Dec 27 '16 at 23:04
  • You need to create an actual plugin file. It needs its plugin header. Update my answer with an example. – yivi Dec 27 '16 at 23:13
