How I get realusername i hybrid mode

[userform3]

Hi,

Your idea was deciding, thanks, I change the Hook Location to showthread_postbit_create
I found in tempalte showthread_list the location where are "bulid" the usernick name, this nickname I want to change to
realname, I try this with following code in this hook:

PHP Code:

$realname ='';
if ($post['field6'] && $post['field5']) {
     $realname =  $post['field6'] . ' ' .  $post['field5'];
}
vB_Template::preRegister('showthread_list',array('userjs' => $realname)); 


It dosen't work.
If I change this code to

PHP Code:

vB_Template::preRegister('showthread_list',array('realname' => $realname)); 


And change the part of template showthread_list to

PHP Code:

...
// cached usernames
pu[0] = guestphrase;
//{vb:raw userjs} // org
{vb:raw realname} // new
// -->
... 


It dosen't wort to.

What make I wrong?
