Prestashop Generate Invoice with user name

Question

I have been trying to find the file where the pdf invoice is generated to change the name of it, to the name of the user, e.g instead "invoice00012", I would like to have "John Smith.pdf". I would appreciate your help. Thanks.

Modify function getFilename() in classes/pdf/HTMLTemplateInvoice.php. You get the customer object using $customer = new Customer((int)$this->order->id_customer);.

public function getFilename()
{   
    $customer = new Customer((int)$this->order->id_customer);

    return $customer->firstname.'_'.$customer->lastname.'.pdf';     
}
