Como ativar "Descrição" Metabox para item de menu programaticamente?

Remova o Descrição No Valor Meta do Usuário ManageNav-MenusColumnShided :

  add_filter ('manage_nav-menus_columns','enable_nav_menu_description_by_default');

funçãoenable_nav_menu_description_by_default ($ colunas)
{
    $ Desc_Key='MANAGENAV-MenusColumnShid';
    $ hidden=get_user_option ($ desc_key);
    $ user_id=wp_get_current_user () - >id;

    Se (! $ oculto)
    {
        update_user_option (
            $ user_id,
            $ Desc_Key,
            Array (0=> 'link-alvo',1=> 'CSS-classes',2=> 'xfn')
        );
    }
    Elseif (False!==($ Key=Array_Search ('Description',$ oculto)))
    {
        Unset ($ hidden [$ Key]);
        update_user_option ($ user_id,$ Desc_Key,$ oculto);
    }

    Retornar colunas $;
}
 

Remove the description from the user meta value managenav-menuscolumnshidden:

add_filter( 'manage_nav-menus_columns', 'enable_nav_menu_description_by_default' );

function enable_nav_menu_description_by_default( $columns )
{
    $desc_key = 'managenav-menuscolumnshidden';
    $hidden   = get_user_option( $desc_key );
    $user_id  = wp_get_current_user()->ID;

    if ( ! $hidden )
    {
        update_user_option(
            $user_id,
            $desc_key,
            array ( 0 => 'link-target', 1 => 'css-classes', 2 => 'xfn' )
        );
    }
    elseif ( FALSE !== ( $key = array_search( 'description', $hidden ) ) )
    {
        unset( $hidden[ $key ] );
        update_user_option( $user_id, $desc_key, $hidden );
    }

    return $columns;
}
