Usergoup Permissions are being controlled through XML files, you don't have to edit usergroup.php anymore

To create your own usergroup permissions, the first thing to do is to modify table usergroup (keep table prefixes in mind!):

[sql]ALTER TABLE usergroup ADD myhackpermissions INT( 10 ) UNSIGNED DEFAULT '0' NOT NULL ;[/sql]

If your hack does need some integer settings as well (and not just On/Off-Options):

[sql]ALTER TABLE usergroup ADD myhackintset INT( 10 ) DEFAULT '100' NOT NULL ;[/sql]

Then you must create a an XML-File bitfield_myhack.xml and place it in includes/xml:

HTML Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<bitfields product="vbulletin">
	<bitfielddefs>
		<group name="ugp">
			<group name="myhackpermissions">
				<bitfield name="canfoo" group="my_hack_permissions"  phrase="can_foo_forum" install="1,2,3,4,5,6,7">1</bitfield>
				<bitfield name="canbaa" group="my_hack_permissions"  phrase="can_baa_forum" install="">2</bitfield>
				<bitfield intperm="true" name="myhackintset" group="my_hack_permissions"  phrase="myhack_int_desc"></bitfield>
			</group>
		</group>
	</bitfielddefs>
</bitfields>
As you can see, you must create a new permission group below group ugp (short for usergroup permissions).

Parameter product of Tag bitfields should be the identifier of your Product

Paramater name of Tag group must match the column name in table usergroup.

The Parameters for Tag bitfield are:
  • name is the identifier you can use in your hack code (eg. $permissions['myhackpermissions'] & $vbulletin->bf_ugp['myhackpermissions']['canfoo'])
    In case of integer options this name must match the column name in table usergroup.
  • intperm indicates that this Option is a integer value
  • group is the varname for the Phrase that should be displayed as Permission Group Title.
    This is also being used to set up different Groups for your permissions.
  • phrase is the varname of the Phrase that should be displayed for this option in Usergroup Manager
  • install is a comma-separated list of the usergroups where this permission should be visible
    If this parameter is empty or omitted, this Option will be used for all Usergroups

The value of <bitfield> is the decimal value of the bit (eg. 1 for the first, 2 for the second, 4 for the third, and so on).
In case of an Integer Option this is the default value.

If you want to hide certain permission groups for some usergroups, for example from Guests as they don't make sense for them:

HTML Code:
<ignoregroups>
        <group name="myhackpermissions" ignoregroups="1" />
</ignoregroups>
Parameter name is the name of the permission group you want to hide, ignoregroups is a comma seperated list of usergoup IDs where this permission group should not show up.
Place this section below the <bitfielddefs>-Section.

Now create the necessary phrases (in Phrasegroup Permissions) at this point.

As vBulletin caches Bitfields in Datastore, you must rebuild this cache before the new usergroup permissions can be actually used (They will already show up in Usergroup Manager, but cannot be saved - you will get an error).
To do so, point your browser to admincp/index.php?do=buildbitfields.

You can also use the following Code (in a Custom Installer or Install-Code of a Product) to update the Bitfield Cache:
PHP Code:
if (is_newer_version('3.5.1'$vbulletin->options['templateversion']))
{
    
// Rebuild Bitfields
    // Do this for vBulletin < 3.5.1 *ONLY*; later versions rebuild
    // automatically and calling the builder in install code causes
    // the bitfields NOT to be rebuild correctly
    
require_once(DIR '/includes/class_bitfield_builder.php');
    
vB_Bitfield_Builder::save($db);
    
build_forum_permissions();

If you install/upgrade vBulletin and custom bitfield_xxx.xml files are already in place, they will be used - you don't have to update the Bitfield Cache in this case.

I don't see any difference other than the group used, and I don't think that's what causes the problem.

Ok, figured that I needed to rebuild bitfields.. But it still does not save.

vbulletin, NOT vBulletin - better yet use your own product id.

I changed the product ID to my own. There are no results though.

As I said, after sumbitting the usergroup options, it says "usergroup X saved", but then after I reload the page, the option is back to "off" (as it was originally)... My latest XML:

Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<bitfields product="dv_ugpefcm">
	<bitfielddefs>
		<group name="ugp">
			<group name="charlimit">
			<bitfield name="isexempt" group="post_thread_permissions" phrase="exempt_from_char_limit" install="">0</bitfield>
			</group>
		</group>
	</bitfielddefs>
</bitfields>

Yes. Using the admincp navbar link in debug mode.

Figured: The problem was that I specified invalid decimal bitfield value. Now it is working (after I changed 0 to 1).

I don't think '' and '0' are valid bitfield values.

1st bitfield should have value of 1
2nd should have 2
3rd should have 4
4th should have 8
5th should have 16
and so on....

Yes, I already figured that, thanks.
It should be mentioned in the first post though.

Even if yes, it is not mentioned that XML uses binary data as the values. YOu did not specify what to put between the tags
