Step 1 – Make sure things are formatted correctly WordPress itself depends on the headers at the top of your main plugin file. In many cases, if your plugin is “My Cool Plugin” this file is my-cool-plugin.php in the main directory of your folder. Make sure the top part of the file follows this format: … Read more
Use the filter update_option_{$option}. It runs after a successful saving. $option is the name of your option, and you get the old and the new value as parameters. From wp-includes/option.php: do_action( “update_option_{$option}”, $oldvalue, $_newvalue ); Use it like this for an option wpse_themesettings: add_action( ‘update_option_wpse_themesettings’, ‘wpse_check_settings’, 10, 2 ); function wpse_check_settings( $old_value, $new_value ) { … Read more

add_action(‘admin_menu’, ‘my_remove_sub_menus’); function my_remove_sub_menus() { remove_submenu_page(‘edit.php’, ‘edit-tags.php?taxonomy=category’); remove_submenu_page(‘edit.php’, ‘edit-tags.php?taxonomy=post_tag’); }
