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.

hi,

Thanks for your explanation verry usefull.One question through.My permissions show up fine the only thing that annoys me a little is that that little help icon that refuses to shoowup nexto my permissions ? i bet it got something todo with the adminhelp manager you see in debug mode ?

buh i hate XML most of the time i doesn't work for me

HTML Code:
<?xml version="1.0" encoding="iso-8859-1"?>
<bitfields product="myproduct">
<bitfielddefs>
<group name="ugp">
<group name="myproductpermissions">
 <bitfield name="canview" group="myproduct_permissions" phrase="can_view" install="2,5,6,7">1</bitfield>
 <bitfield name="canmanage" group="myproduct_permissions" phrase="can_manage" install="2,5,6,7">2</bitfield>
</group>
</group>
</bitfielddefs>
</bitfields>
can't even choose between yes or no i can change it and vbulletin says options saved successfully but when i goback to check .... (you can guess)the value doesn't change

Code:
"ALTER TABLE " . TABLE_PREFIX . "usergroup ADD myproductpermissions INT(10) UNSIGNED NOT NULL DEFAULT 0";
really hate XML :devious:

Just an FYI, for those interested in having custom forum permissions that correspond with custom usergroup permissions, you may want to check out my hack discussed in the following thread:

There is a reason why there is no built-in support for custom forum permissions

What is that reason, for those of us new to the game? I'm trying to get my head around expanding vB's permissions system and would appreciate any insights.

I wonder why the "INSTALL" bit never works correctly. If I install such xml, all settings are initially off, regardless of install value.

thanks Andreas for this nice custom usergroup permission howto...

i used to make my usergroup permissions with a plugin in the hook 'admin_usergroup_edit', but i needed 1 column in 'usergroup' table for each permission (too bad for lots of new perms)

but now this xml really rocks

So can you just do:
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</bitfield>
			</group>
		</group>
	</bitfielddefs>
</bitfields>
And then the query
PHP Code:
ALTER TABLE usergroup ADD myhackpermissions INT( 10 ) UNSIGNED DEFAULT '0' NOT NULL ; 
To add a Yes/No?

I couldn't get it to work so I made my own function in the hook "global_start".
I kept everything else the same but removed "can_administer".

I had to use this query to add the field to the "administrator" table.
PHP Code:
$db->query_write("ALTER TABLE `" . TABLE_PREFIX . "administrator` ADD hostingadminperms INT( 10 ) UNSIGNED DEFAULT '0' NOT NULL ;"); 

I put this in global_start
PHP Code:
function can_admin_hosting()
{
  global $vbulletin, $db;

  $getuserperms = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "administrator WHERE userid='".$vbulletin->userinfo['userid']."' ");
    $perms = $db->fetch_array($getuserperms);
 
  return $perms['hostingadminperms'];

} 
In your admin backend file I just used
PHP Code:
can_admin_hosting();

Very helpfull topic. Could you please extend it a bit saying me how I can set a default value per bitfield (for all usergroups) ?

I've the following code in bitfield_vbmates.xml
Code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<bitfields product="vbmates">
	<bitfielddefs>
		<group name="ugp">
			<group name="vbmates">
				<bitfield name="canuse" group="vbmates_permissions" phrase="vbmates_can_use">1</bitfield>
                <bitfield name="canadd" group="vbmates_permissions" phrase="vbmates_can_add">2</bitfield>
..... and others below..........
			</group>
		</group>
	</bitfielddefs>
</bitfields>
Then I setup correctly persmissions per user group. Why with the code:

Code:
if(!$permissions['vbmates'] & $vbulletin->bf_ugp['vbmates']['canadd']){
    $vbulletin->url = "vbmates.php?" . $vbulletin->session->vars['sessionurl'] ."";
    eval(print_standard_redirect('vbmates_no_add_profile', true, true));
}
a usergroup can go on while they dont have permission for it? Please note:
1.- I changed bitfield_vbmates.xml after the first product installation
2.- I've also trying to use in this file: <group name="vbmates_permissions"> but no chance.

Ok, I found it. It needed one couple of parenthesis more. Instead of:
if(!$permissions['vbmates'] & $vbulletin->bf_ugp['vbmates']['canadd'])
should be ...
if(!($permissions['vbmates'] & $vbulletin->bf_ugp['vbmates']['canadd']))

Hi, can you help me a bit in this problem?

My bitfield_get_direct_links.xml:
HTML Code:
<?xml version="1.0" encoding="ISO-8859-1"?>

<bitfields product="get_direct_links">
	<bitfielddefs>
		<group name="ugp">
 			<group name="get_direct_links_permissions">
				<bitfield intperm="true" name="get_direct_links_number" group="get_direct_links_permissions" phrase="get_direct_links_number_desc">5</bitfield>
			</group>
		</group>
	</bitfielddefs>
</bitfields>
In UserGroupt Manager, it work well but in my php code, when I call
PHP Code:
var_dump($vbulletin->bf_ugp); 
I can't find my get_direct_links_permissions. And when I call
PHP Code:
var_dump($permissions['get_direct_links_permissions']); 
It is NULL

Can you help me? Thank you very much!

PS: Sorry for my bad English

I have some problems with an int bitfield.

<bitfield intperm="true" name="myhackintset" group="my_hack_permissions" phrase="myhack_int_desc"></bitfield>

Its baiscally like this one, only difference is it installs to all usergroups, including custom usergroups. Well my problem is this, i want to check if a person is in two usergroups, but one of the usergroups bitfield is set to 0. Example, Registered usergroup setting is 0, but Custom usergroup setting is 1. Instead of taking the 1 as the value, i need the 0.

Anyway to do this? Hope thats clear.

Hello.

How to change a custom bitfield_xx.xml parameter via vB Options?

For example, as I add new usergroups, I want to update the 'install' or 'ignore' param (e.g. comma-separated value) via ACP vs. editing the file.

Is that possible e.g. putting an ACP variable in the xml file?

Thanks in advance.

Update: Using a variable in the 'xml' file is not necessary but vB requires code revisions in order to update bitfield 'usergroups' via ACP vs. modifying 'bitfield_xx.xml' file. It may be better to work with the 'ignoregroups' feature in usergroups.php combined with vBulletin Options' User Profile Options instead of the 'install' parameter of the 'xml' file since 'ignoregroups' works in v.3.6.3 after installation whereas, it seems that the 'install' parameter of <bitfields> is only recognized during new installations.
