WPINC . ‘/ms-blogs.php’ ); require( ABSPATH . WPINC . ‘/ms-settings.php’ ); } elseif ( ! defined( ‘MULTISITE’ ) ) { define( ‘MULTISITE’, false ); } … Read more
There is no function for that. But you can use a custom SQL query like this … SELECT meta_key, meta_value FROM $wpdb->sitemeta WHERE site_id = $wpdb->siteid AND `meta_key` NOT LIKE ‘_site_transient%’ ORDER BY meta_key … to get all non-transient options. Basic example: /** * Plugin Name: T5 Multi-Site Options * Description: Add a page to … Read more
Apparantly this happens with the newer version of domain mapping because sunrise.php itself needs to be updated. To solve it I: Copy the new sunrise.php file from wp-content/plugins/wordpress-mu-domain-mapping/sunrise.php to wp-content/sunrise.php and you’ll be fine. And it works now.
You can use is_plugin_active_for_network( $plugin )
The capabilities are stored as user meta data in a serialized array for each site.

It … Read more
wp_get_current_user() is a pluggable function and not yet available when your plugin is included. You have to wait for the action plugins_loaded: Example: add_action( ‘plugins_loaded’, ‘wpse_92517_init’ ); function wpse_92517_init() { if(!is_super_admin()) add_action(‘widgets_init’,’my_unregister_widget’); } function my_unregister_widgets() { unregister_widget( ‘WP_Widget_Pages’ ); unregister_widget( ‘WP_Widget_Calendar’ ); } Or move the check into the widget function: add_action( ‘widgets_init’, ‘my_unregister_widget’ ); … Read more
You might have a look at the WordPress Transient API. You should be able to store your shortcode output $total_network with set_transient( ‘my_shortcode_cache’, $total_network, WEEK_IN_SECONDS ); where WEEK_IN_SECONDS is a built in constant equal to 604800. You can then fetch it with: get_transient( ‘my_shortcode_cache’ ); If you need it to work network wide there exists … Read more
I’m using the REST API to pull data about one multisite installation and feed it to sites in another multisite installation. Here’s some of the code in use: class WPSE205354_Demo { function __construct() { add_filter( ‘json_endpoints’, array( $this, ‘register_routes’ ) ); } /** * Register the additional API routes * @param array $routes The routes … Read more
