theme options select categoria no guarda

[mumraa]

pero claro!, esto es un poco de lo que ya tenia funcionando.. (y sigue funcionando, solo que el select no se guarda)..

Código:

if ( function_exists('register_sidebar') )

$themename = "XXXXXXXXX";
$shortname = "tmt";
$options = array (

array(    "name" => "Selección de categorías para el menú principal",
        "type" => "title"),
array(    "type" => "open"),
array(    "name" => "Categorías: ",
        "desc" => 'Máximo ideal: 8".',
        "id" => $shortname."_lista_categorias",
        "std" => "",
        "type" => "categoria"),
array(    "type" => "close"),
);
function mytheme_add_admin() {
    global $themename, $shortname, $options;
    if ( $_GET['page'] == basename(__FILE__) ) {
        if ( 'save' == $_REQUEST['action'] ) {
                foreach ($options as $value) {
                    update_option( $value['id'], $_REQUEST[ $value['id'] ] ); }

                foreach ($options as $value) {
                    if( isset( $_REQUEST[ $value['id'] ] ) ) { update_option( $value['id'], $_REQUEST[ $value['id'] ]  ); } else { delete_option( $value['id'] ); } }

                header("Location: themes.php?page=functions.php&saved=true");
                die;
        } else if( 'reset' == $_REQUEST['action'] ) {
            foreach ($options as $value) {
                delete_option( $value['id'] ); }
            header("Location: themes.php?page=functions.php&reset=true");
            die;
        }
    }
    add_menu_page($themename." Options", "".$themename." Options", 'edit_themes', basename(__FILE__), 'mytheme_admin');
}

function mytheme_admin() {

    global $themename, $shortname, $options;

    if ( $_REQUEST['saved'] ) echo '<div id="message" class="updated fade"><p><strong>'.$themename.' settings saved.</strong></p></div>';
    if ( $_REQUEST['reset'] ) echo '<div id="message" class="updated fade"><p><strong>'.$themename.' settings reset.</strong></p></div>';

?>
