[userform3]

Hi,

In forum, vbulletin version 5.2.5, I would like to create a new extension.

To the facts, the forum is only accessible to registered users, if a user is not registered, he can see the forum, not.
If the user is registered, his real first name and last name should be displayed.
These data are located in a separate table in the forum database and must be read out additionally.

To implement this, we introduced a new product in the area "Products & Hooks" in "Manage Products" with the name "klarnamenIntern".
A new add-on was created in "Manage Hooks". To test with "klarnamen".
In the directory .../forum5/core/packages/klarnamenIntern the following directories with files were created:

klarnamenIntern/api/site.php
klarnamenIntern/xml/product_klarname.xml
product.php

Unfortunately, I can not access the forum data via the procedure described above.
That is, About the file klarnamenIntern/api/site.php I can not read posts from the forum.

What is the error or the causes why I can not access the data?
How can I access the PHP files klarnamenIntern/api/site.php from the forum or connect?

Example the file klarnamenIntern/api/site.php

PHP Code:

<?php if(!defined('VB_ENTRY')) die('Access denied.');

class Interred_Api_Site extends vB_Api_Extensions 
{
    protected $product = 'klarnamenIntern';
