admin include page parameter

[surferbloggy]

hi! another problem: i have this function:

    function show_menu()  {
    
        
        switch ($_GET['page']){
            case "show_orders_page" :
                include_once ( dirname (__FILE__) . '/show_orders.php' );        // nggallery_admin_options
                show_orders_page();
                
                break;
                
            case "deliver_orders_page" :
                include_once ( dirname (__FILE__) . '/show_orders.php' );    
                //include_once ( dirname (__FILE__) . '/deliver_order.php' );    
                  
                deliver_orders_page();
                
                break;
        }
    }

if the link is
wpdemo/wp-admin/admin.php?page=show_orders_page
the include works, the function works everything is ok instead

if the link is /wp-admin/admin.php?page=deliver_orders_page&iduser=1
it tells me:
You do not have sufficient permissions to access this page.

what can I do??

Each page needs to be added using the admin subpage function. If you don't want multiple menu links/pages add a single page as parent and then use a query variable to switch pages.
add_subpage(yourpluginmainpage)
so you get ?page=yourpluginmainpage
and can link to ?page=yourpluginmainpage&view=show_orders_page etc.
