Well, seeing as no one's responded, I'm going to assume no one knew a quick way to go about creating a friends cap. I ended up creating one, though it's not pretty and requires editing the profile.php file.


To start with, anywhere at the top of profile.php where the global variables are being declared, add one of your own to use as your maximum cap. Obviously set it to whatever you want your cap to be.

PHP Code:

$friendlimit = 1000; 


After that there are three sections of code we'll need to edit in various places: Request addlist, Post addlist, and Post updatelist. They each get used at different times, it seems, so there is quite a bit of code repetition.

$_REQUEST['do'] == 'addlist'
Near the top, just before

PHP Code:

if ($vbulletin->GPC['userlist'] == 'buddy' OR $vbulletin->GPC['userlist'] == 'friend') 


you'll need to add in

PHP Code:

$numresult = $db->query_read("
    SELECT COUNT(*) AS friendcount FROM " . TABLE_PREFIX . "userlist AS userlist 
    WHERE userlist.userid = " . $vbulletin->userinfo['userid'] . " 
    AND friend = 'yes'
");
$numarray = $db->fetch_array($numresult);
$myfriendcount = $numarray["friendcount"];
global $friendlimit; 


Then a little further down, just inside of this if statement

PHP Code:

if ($vbulletin->GPC['userlist'] == 'friend') 


you need to add

PHP Code:

if ($myfriendcount >= $friendlimit)
    eval(print_standard_redirect("You cannot have more than $friendlimit friends.", false, true));
else 


$_POST['do'] == 'doaddlist'
This code is almost identical to the previous section, and so are the pieces we're going to add.

At the beginning, just after this referrer check

PHP Code:

if ($vbulletin->url == $vbulletin->options['forumhome'] . '.php')
{
    $vbulletin->url = 'member.php?' . $vbulletin->session->vars['sessionurl'] . "u=$userinfo[userid]";
} 


Add in the same query from above

PHP Code:

$numresult = $db->query_read("
    SELECT COUNT(*) AS friendcount FROM " . TABLE_PREFIX . "userlist AS userlist 
    WHERE userlist.userid = " . $vbulletin->userinfo['userid'] . " 
    AND friend = 'yes'
");
$numarray = $db->fetch_array($numresult);
$myfriendcount = $numarray["friendcount"];
global $friendlimit; 


Then inside the 'friend' part of the case statement

PHP Code:

switch ($vbulletin->GPC['userlist'])
{
    case 'friend': 


Add the count check again.

PHP Code:

if ($myfriendcount >= $friendlimit)
    eval(print_standard_redirect("You cannot have more than $friendlimit friends.", false, true)); 


$_POST['do'] == 'updatelist'
This one is a bit different than the previous two and requires more edits.

Pretty much right at the 'profile_updatelist_start' hook, add the query again:

PHP Code:

$numresult = $db->query_read("
    SELECT COUNT(*) AS friendcount FROM " . TABLE_PREFIX . "userlist AS userlist 
    WHERE userlist.userid = " . $vbulletin->userinfo['userid'] . " 
    AND friend = 'yes'
");
$numarray = $db->fetch_array($numresult);
$myfriendcount = $numarray["friendcount"];
global $friendlimit; 


Then, after the last AND of this if statement, but before the closing parenthesis

PHP Code:

if
(
    $vbulletin->GPC_exists['makefriends']
    AND $vbulletin->options['socnet'] & $vbulletin->bf_misc_socnet['enable_friends']
    AND $vbulletin->userinfo['permissions']['genericpermissions2'] & $vbulletin->bf_ugp_genericpermissions2['canusefriends']
    AND $userinfo['permissions']['genericpermissions2'] & $vbulletin->bf_ugp_genericpermissions2['canusefriends']
) 


Add the line

PHP Code:

AND $myfriendcount < $friendlimit 


Now, right before this if statement

PHP Code:

if
(
    !($vbulletin->options['socnet'] & $vbulletin->bf_misc_socnet['enable_friends'])
    OR !($vbulletin->userinfo['permissions']['genericpermissions2'] & $vbulletin->bf_ugp_genericpermissions2['canusefriends'])
    OR !($userinfo['permissions']['genericpermissions2'] & $vbulletin->bf_ugp_genericpermissions2['canusefriends'])
    OR $vbulletin->userinfo['userid'] == $userinfo['userid']
)
{
    continue;
} 


Add the following

PHP Code:

if ($myfriendcount >= $friendlimit)
    break;
else 


Lastly, find the line

PHP Code:

if ($vbulletin->GPC['incomingaction'] == 'accept') 


And replace it with

PHP Code:

if ($vbulletin->GPC['incomingaction'] == 'accept' && ($myfriendcount < $friendlimit)) 


That seems to be catching all paths to friend adding and filtering it appropriately.
