17 /* This file contains all the functions used for the ban center.
18
19 void Ban()
20 - the main entrance point for all ban center functions.
21 - is accesssed by ?action=admin;area=ban.
22 - choses a function based on the 'sa' parameter.
23 - defaults to BanList().
24 - requires the ban_members permission.
25 - initializes the admin tabs.
26 - load the ManageBans template.
27
28 void BanList()
29 - shows a list of bans currently set.
30 - is accesssed by ?action=admin;area=ban;sa=list.
31 - uses the main ManageBans template.
32 - removes expired bans.
33 - allows sorting on different criteria.
34 - also handles removal of selected ban items.
35
36 void BanEdit()
37 - the screen for adding new bans and modifying existing ones.
38 - adding new bans:
39 - is accesssed by ?action=admin;area=ban;sa=add.
40 - uses the ban_edit sub template of the ManageBans template.
41 - modifying existing bans:
42 - is accesssed by ?action=admin;area=ban;sa=edit;bg=x
43 - uses the ban_edit sub template of the ManageBans template.
44 - shows a list of ban triggers for the specified ban.
45 - handles submitted forms that add, modify or remove ban triggers.
46
47 void BanEditTrigger()
48 - the screen for adding new ban triggers or modifying existing ones.
49 - adding new ban triggers:
50 - is accessed by ?action=admin;area=ban;sa=edittrigger;bg=x
51 - uses the ban_edit_trigger sub template of ManageBans.
52 - editing existing ban triggers:
53 - is accessed by ?action=admin;area=ban;sa=edittrigger;bg=x;bi=y
54 - uses the ban_edit_trigger sub template of ManageBans.
55
56 void BanBrowseTriggers()
57 - screen for showing the banned enities
58 - is accessed by ?action=admin;area=ban;sa=browse
59 - uses the browse_triggers sub template of the ManageBans template.
60 - uses sub-tabs for browsing by IP, hostname, email or username.
61
62 array BanLog()
63 - show a list of logged access attempts by banned users.
64 - is accessed by ?action=admin;area=ban;sa=log.
65 - allows sorting of several columns.
66 - also handles deletion of (a selection of) log entries.
67
68 string range2ip(array $low, array $high)
69 - reverse function of ip2range().
70 - converts a given array of IP numbers to a single string
71 - range2ip(array(10, 10, 10, 0), array(10, 10, 20, 255)) returns
72 '10.10.10-20.*
73
74 array checkExistingTriggerIP(array $ip_array, string $fullip)
75 - checks whether a given IP range already exists in the trigger list.
76 - if yes, it returns an error message. Otherwise, it returns
77 an array optimized for the database.
78
79 void updateBanMembers()
80 - updates the members table to match the new bans.
81 - is_activated >= 10: a member is banned.
