How to modify a function (PHP) between hooks

[Carnage]

well, you could always change the value of usergroup id to say 'a' in the first hook then change it back in the second.

1st hook

PHP Code:

if ($vbulletin->userinfo['usergroupid'] == '6')
{
     $vbulletin->userinfo['usergroupid'] = 'a'
} 


2nd hook

PHP Code:

if ($vbulletin->userinfo['usergroupid'] == 'a')
{
     $vbulletin->userinfo['usergroupid'] = '6';
} 

if (is_member_of($vbulletin->userinfo['usergroupid'], explode("|", $vbulletin->options['post_thanks_who_delete_all'])))
{
   return true;
}
