Prestashop, Generating invoice(pdf) automatically

Question

So I'm looking for a solution to save invoice automatically into my server folder, when I press view invoice as the generated URL occurs (http://www.example.com/admin11111/index.php?controller=AdminPdf&token="token"&submitAction=generateInvoicePDF&id_order="id").

I also did research on google, but this solution, somehow didnt work for me: https://www.prestash...es-in-a-folder/

From Prestashop Forum I got advice that I should use shell script, but using a shell download like wget or other only gets me html file, because when I download the invoice in Prestashop backoffice.. it takes some time to generate and the download save appears later.

With this 2 overrides you could accomplish this.

Override PDF.php:

class PDF extends PDFCore
{
    public function render($display = true)
    {
        if($this->template == PDF::TEMPLATE_INVOICE)
            parent::render('F', true);

        return parent::render($display);
    }
}

Override PDFGenerator.php:

class PDFGenerator extends PDFGeneratorCore
{
    public function render($filename, $display = true)
    {
        if (empty($filename)) {
            throw new PrestaShopException('Missing filename.');
        }

        $this->lastPage();

        if ($display === true) {
            $output = 'D';
        } elseif ($display === false) {
            $output = 'S';
        } elseif ($display == 'D') {
            $output = 'D';
        } elseif ($display == 'S') {
            $output = 'S';
        } elseif ($display == 'F') {
            $output = 'F';
            $filename = _PS_ROOT_DIR_.'/'.$filename;
        } else {
            $output = 'I';
        }

        return $this->output($filename, $output);
    }
}

Remember to choose another folder other than _PS_ROOT_DIR_. This was just for testing. Try $filename = _PS_ROOT_DIR_.'/../invoices/'.$filename; so it's not a public folder (and you must create the folder with the correct permissions.
