Access to directory partition for only one group?

Question

1C-Bitrix

Hey! Tell me, how can I remove access for one group for a directory partition, but leave accessibility for the "all users" group?

Answer 1

Such a restriction is possible only in the public part (search is not taken into account), or with strong customization (either your own level of rights, or events + public).
The fact is that the Bitrix rights system determines the maximum rights to access the system (with the exception of showing the administrative panel and excluding groups when mapping in AD).
Thus, if a user is in both groups, then he will see this section, as the "all users" group sees it.
Or you need to create an additional group, where to include everyone except the users of this group.

Answer 2

if(in_array($group_id, $USER->GetUserGroupArray())){
echo 'user in group '.$group_id;
}
