Hello, i have 3 User Groups. But i want to make that group 1 and 2 cant send private messages to group 3. And group 3 not to 1 and 2.
The right Hook is "private_insertpm_process", but i need the code for the check when the user sends a message.

When a user from group 1 send a message to a user from group 3 i want to become a custom error message.

Sorry, but i'm not soooo good in the code.
Thank you guys!

before data manager processing "send message", you must run sql query to grab usergroups of selected users
look function set_recipients() in data manager file class_dm_pm.php
this func can help you to understand how this work =)

...and i understand nothing. ^^

Now i have loaded class_dm_pm.php and opened it with Dreamweaver.
It looks good, but i have no idea what i can write for the check.

Maybe if ($vbulletin->userinfo['usergroupid'] == 1) and than the check command. But im a noob in coding. :(

Now i have tested it with if ($vbulletin->userinfo['usergroupid'] == 1) and a error message, but it dont works. :(

Any idea?

I NOT tested this code, use it at your own risk =)

PHP Code:

$user_groups_allowed_from = '2,6';
$user_groups_allowed_to = '2,5,6,7';
// #### end config ####
$vbulletin->userinfo['allowed_ug_from'] = explode(",", $user_groups_allowed_from);
$vbulletin->userinfo['allowed_ug_to'] = explode(",", $user_groups_allowed_to);
if(!empty($vbulletin->userinfo['allowed_ug_from']) AND is_member_of($vbulletin->userinfo, $vbulletin->userinfo['allowed_ug_from']))
{
      if(!empty($pm['recipients']))
      {
            if(preg_match('/(?<!&#[0-9]{3}|&#[0-9]{4}|&#[0-9]{5});/', $pm['recipients'])) // multiple recipients attempted
            {
                  $recipientlist = preg_split('/(?<!&#[0-9]{3}|&#[0-9]{4}|&#[0-9]{5});/', $pm['recipients'], -1, PREG_SPLIT_NO_EMPTY);
                  foreach($recipientlist AS $recipient)
                  {
                        $recipient = trim($recipient);
                        if($recipient != '')
                        {
                              $names[] = htmlspecialchars_uni($recipient);
                        }
                  }
            }else{
                  $names[] = htmlspecialchars_uni($recipientlist);
            }
            // query recipients
            $checkusers = $vbulletin->db->query_read("
                  SELECT user.userid, user.username, user.usergroupid, user.membergroupids
                  FROM " . TABLE_PREFIX . "user AS user
                  WHERE user.username IN('" . implode('\', \'', array_map(array($vbulletin->db, 'escape_string'), $names)) . "')
                  ORDER BY user.username
            ");
            $allowed_ug_user = array();
            while($checkuser = $vbulletin->db->fetch_array($checkusers))
            {
                  if(is_member_of($checkuser, $vbulletin->userinfo['allowed_ug_to']))
                  {
                        $allowed_ug_user["$checkuser[userid]"] = $checkuser;
                  }
            }
            $vbulletin->db->free_result($checkusers);
            if(empty($allowed_ug_user))
            {
                  print_no_permission();
                  // Or your custom ERROR
            }
      }
} 


Thank you, but how can i use this code?
When i put it into class_dm_pm.php is nothing.

create new module
product - vbulletin
hook - private_insertpm_process
php code - code above
==
and...
you must define your values in the "config" - first 2 lines of my code

Okay. But i have a question.
When i define from 5 to 6, can 6 write a pm to 5?

It works! Thank you!
How i can now define a custom error message?

create new phrase
phrase type - error messages
variable - test_var_error <= create your own "readable" variable!
text - your text

in the module put this code instead of print_no_permission()

$errors[] = fetch_error('test_var_error');

It works! Thanks!
