XF 2.2 How to get User data in templatePostRender?

[jb-net]

Hi,

my goal is to dynamically replace some html code in all E-Mails based on the selected language of the user (receiver of that E-Mail).

I therefore created a simple addon, inspired by the code in this discussion (https://xenforo.com/community/threads/parsing-smilies-in-emails.166295/) which works great as is it is. But I don't want it to change every E-Mail but only E-Mails send to users with a specific Language ID (in my case language_id = 4)

I tried to extend the if statement:

<?php

namespace emailreplace;

use XF\Mvc\Entity\Entity;
use XF\Entity\User;

class Listener
{
   public static function templatePostRender(\XF\Template\Templater $templater, $type, $template, &$output)
   {
      if ($type !== 'email') {
         return;
      }

      $visitor = \XF::visitor();
      if ($type == 'email' AND $visitor->language_id == '4') {
      $output = strtr($output, 'replace_this', 'with_that');
      }
   }
}

but it doesn't work.

Any ideas / suggestions / hints?

Thanks!

@Chris D / @Brogan : Maybe any idea how I could query the user data (language) of the E-Mail receiver?
