Use | Prerequisite | Install | Filters | Demo | Changelog

For the super admin, replace WP Admin Bar My Sites menu with an All Sites menu.

• Doesn't use switch_to_blog(), i.e. Super Admin All Sites Menu is faster and uses less resources than the WP Admin Bar My Sites menu.
• Subsite menu data are stored locally in IndexedDB (did I say it's fast?). The local storage is updated when;
  • the plugin is activated.
  • a site is added or deleted.
  • you change a blog name.
  • IndexedDB is out of sync with site changes.
  • Restricted Site Access is activated or deactivated.
• When subsite menu data is updated, REST is used and it's done in increments (100 sites per increment).
• List all subsites. WP Admin Bar My Sites only list sites you're a local admin on.
• Mark sites that has restricted site access with a red icon.
• Sites menu is sorted alphabetically.
• Search filter.
• Add more menu choices:
  • Under "Network Admin"
    • Add New Site
  • Per subsite.
    • 'New Page'
    • 'Users'
    • 'Plugins'
    • 'Settings'

Inspired by WP REST API vs admin-ajax.php vs Must-Use Plugin: Handling AJAX Requests in WordPress, I wrote a must-use plugin that makes the plugin go from fast to faster (ca 60% faster). Save the file in mu-plugins.

    Note: Must be an array and each element in the array must point to the main plugin file. Syntax 'plugin-dir/plugin-file.php'

   add_filter( 'all_sites_menu_plugin_trigger', function( array $plugins ) : array {

  		'myplugin/myplugin.php',
  	];
  } );

• all_sites_menu_search_threshold
  • Don't display search field if there's less than N subsites. Default value is 20.
