RSS should have permissions checking

• Error

Here is a tweak that fixes it - the issue was category views - can someone modify tikilib.php and check in?

// Function that checks for:
// - tiki_p_admin
// - the permission itself
// - individual permission
// - category permission
// if O.K. this function shall replace similar constructs in list_pages and other functions above.
// $categperm is the category permission that should grant $perm. if none, pass 0
function user_has_perm_on_object($user,$object,$objtype,$perm,$categperm='tiki_p_view_categories') {
global $feature_categories;
global $userlib;
// superadmin

if($userlib->user_has_permission($user, 'tiki_p_admin')) {
return(TRUE);
}
//mod changed order
// no individual and no category perms. So has the user the perm itself?
if (is_array($perm)) {
foreach($perm as $p) {
if(!$userlib->user_has_permission($user, $p)) {
return(FALSE);
}
}
} else {
if(!$userlib->user_has_permission($user, $perm)) {
return(FALSE);
}
}

if ($userlib->object_has_one_permission($object, $objtype)) {
// wiki permissions override category permissions
//handle multiple permissions
if(is_array($perm)) {
foreach($perm as $p) {
if(!$userlib->object_has_permission($user, $object, $objtype,$p)) {
return(FALSE);
}
}
} else {
if (!$userlib->object_has_permission($user, $object, $objtype,$perm))
{
return(FALSE);
}
}
return (TRUE);
} elseif ($feature_categories 'y'&& $categperm ! 0) {

// no wiki permissions so now we check category permissions tiki_p_view_categories
global $categlib;
if (!is_object($categlib)) {
include_once('lib/categories/categlib.php');
}
unset($tiki_p_view_categories); // unset this var in case it was set previously
$perms_array = $categlib->get_object_categories_perms($user, $objtype, $object);
if ($perms_array) {
$is_categorized = TRUE;
foreach ($perms_array as $p => $value) {
$$p = $value;
}
if ($tiki_p_admin_categories 'y' && $tiki_p_view_categories 'n')
$tiki_p_view_categories = 'y';
} else {
$is_categorized = FALSE;
}

if ($is_categorized && !empty($categperm) && $$categperm == 'y') {
//
return(TRUE);
} else {
return(FALSE);
}
// if it has no category perms or the user does not have
// the perms, continue to check individual perms!
}

return(TRUE);
}
