In Prestashop 1.6, from a FrontController, I have to send a mail to the administrator of the Shop. 

This part works well but I got problems to include a link to the administration page of a specific customer.

The only thing I miss is the name of the administration directory. I would be able to parse and concatenate the `PS_ADMIN_DIR` constant but it is not available from the FrontController. 

I'm kinda stuck here.

Here is the code : 

```
$admin_customer_link = 
    _PS_BASE_URL_
    .__PS_BASE_URI__
    /* Missing the Administration directory name here */
    .$this->context->link->getAdminLink('AdminCustomers', false)
    ."&id_customer=".(int)$customer->id."&viewcustomer";

```

The output I got : 

> 
> 
> ```
> http://127.0.0.1:8080/prestashop/index.php?controller=AdminCustomers&id_customer=2&viewcustomer
> 
> ```
> 
> 

The output I need : 

> 
> 
> ```
> http://127.0.0.1:8080/prestashop/administration/index.php?controller=AdminCustomers&id_customer=2&viewcustomer
> 
> ```
> 
> 

Any help will be appreciated.
