Listing child pages depending on user capability (role)

Question

I need to list within a sidebar menu all child pages from the current parent page. The children pages are restricted for viewing by user roles, let's say "A" and "B" for now. I use the "Members Plugin" to manage that.

I've created a function that works pretty well for listing these child pages but I can't find the way to NOT LIST the child pages which the current user has no access to.

So if i'm logged in as user with role "A", I can not see the child pages which role "B" has access, and vice versa.

Here's the current code.

Any help/hint would be appreciated.

Thank you !

If the Rol is in the meta you have to get the IDs of all of them then compare the meta access rol to the rol of the user:

    $post_parent_ID = $post->post_parent ? $post->post_parent : $post->ID;

    $title = $post->post_parent ? get_the_title( $post->post_parent ) : get_the_title( $post->ID );
    //we use get posts to get all posts for the given ID
    $children_pages_array = get_posts(array('numberposts' => -1, 'post_status' => 'publish', 'post_type' => 'any', 'post_parent' => $post_parent_ID, 'suppress_filters' => false));
    //we get the user rol
    $user_role = sb_get_user_role();
    //here we create an array that will be populated with IDs
    $ID_pages_rol_array = array();
    foreach ($children_pages_array as $child_page_obj) {
        //we get the rol that can access this page
        $page_role = get_post_meta($child_page_obj->ID, '_members_access_role');
        //do the current user rol have access to this page?
        if ($page_role == $user_role) {
            //yes it does add to the IDs of pages that this rol can access
            array_push($ID_pages_rol_array, $child_page_obj->ID);
        }
    }
    $children = wp_list_pages(array(
        'title_li' => '',
        'include' => $ID_pages_rol_array, //lets send those IDs to be formatted as list items
        'echo' => 0,
        'depth' => 1
            ));

you can get the IDs with get_posts (actually the entire post object) after making the array of permitted IDs, that can be send to wp_list_pages.
