@JonathonByrd’s answer is probably ‘best’ – certainly you should using get_option if at all possible, since there’s no guarantee the option name will stay the same between WordPress versions. Similarly – @JonathonByrd also relies on using a global variable which may be removed/renamed (though perhaps very unlikely). Unfortunately there are no public wrappers which we … Read more

If you want to add your own sub-menu/page to the Settings parent menu: add_action(‘network_admin_menu’, ‘add_my_netw_settings_page’); function add_my_netw_settings_page() { add_submenu_page( ‘settings.php’, ‘Co za asy’, ‘Co za asy’, ‘manage_network_options’, ‘my-netw-settings’, ‘your_form’ ); } function your_form(){ $options = get_site_option(‘your_plugin’); ?> <form action=”<?php echo … Read more
