https://vborg.vbsupport.ru/showthrea...=111870&page=4 and now i can't access my forum AT ALL, not the admin panel nothing, how can i remove this?
I went to vB AdminCP, go to Plugin System > Add New Plugin.
Under Hook Location, scroll down to select 'global_start'.
In the 'Plugin PHP Code' field, copy/paste your edited control
script from Part I.
// Place user in/out of single usergroup
// according to yes/no selection made in profile, via
// custom radio button field. ver 1.04
// Enter values in the strings below for your forum
// custom field containing your radio button
$radio_field = 'field10';
// Text returned for 'yes' choice
$join = 'Female';
// Usergroup to enter/exit
$ug = '33';
// You don't need to enter anything below here.
// Derive additional needed variables
// userid of user
$userid = ($vbulletin->userinfo['userid']);
// current usergroups as array
$ugarr = explode(',' , (''.$vbulletin->userinfo['membergroupids']));
// current radio button setting
$fieldval = $vbulletin->userinfo[$radio_field];
// Do the work
// Proceed only if there is a user choice
if ($fieldval != '')
{
// If yes, add to usergroups
if ($fieldval == $join)
{
$ugarr = IntoGroup($ugarr, $ug, $userid);
}
// Else no, remove from usergroups
else
{
$ugarr = OutOfGroup($ugarr, $ug, $userid);
}
}
