Set options for all WordPress Multisite blogs

README.md

Forked Update options on all WPMS blogs

I used this code snippet as part of a WordPress Multisite plugin, to allow me to quickly set some options for all the blogs on a WordPress Multisite installation.

functions.php

<?php

function set_options($blog_id = null)
{
    if ($blog_id) {
        switch_to_blog($blog_id);
    }

    add_option('bla', 'bla');
    update_option('bla', 'bla');
    
    if ($blog_id) {
        restore_current_blog();
    }
}

function update_options()
{
    global $wpdb;
    
    $blogs = $wpdb->get_results("
        SELECT blog_id
        FROM {$wpdb->blogs}
        WHERE site_id = '{$wpdb->siteid}'
        AND archived = '0'
        AND spam = '0'
        AND deleted = '0'
    ");
    
    foreach ($blogs as $blog) {
        set_options($blog->blog_id);
    }
    
    $message = __('All blogs updated.');
        
}
