Eu tenho acompanhado a série de tutoriais da API de configurações do WordPress desse cara:
Até agora, eu consegui fazer o básico. Agora, ao implementar a guia, estou enfrentando um problema.
Problema 1: as guias não estão funcionando. Todos os campos estão sendo exibidos nas duas guias. A seção 1 deve ser exibida na guia um e a seção 2 na guia dois.
Problema 2: a opção 2 não está sendo salva. Estava funcionando bem antes de implementar as guias.
Código:

/* Add Menu Page */
/* ----------------------------------------------------------------------------- */
function add_my_menu() {
add_menu_page (
'Page Title', // page title
'Menu Title', // menu title
'manage_options', // capability
'my-menu-slug', // menu-slug
'my_menu_page', // function that will render its output
get_template_directory_uri() . '/assets/ico/theme-option-menu-icon.png' // link to the icon that will be displayed in the sidebar
//$position, // position of the menu option
);
}
add_action('admin_menu', 'add_my_menu');
function my_menu_page() {
?>
<?php
if( isset( $_GET[ 'tab' ] ) ) {
$active_tab = $_GET[ 'tab' ];

Não estou muito familiarizado com a API de configurações, mas, à primeira vista, parece que todos os seus campos pertencem a uma única seção de configurações, que você exibe nas duas guias.

@ Milo eu consegui trabalhar, mas eu diria que a API de configurações do WordPress é muito confusa de entender. Além disso, possui quase zero documentação oficial.
