Modification ps_emailalerts for PDF invoice attach.

[viki]

I have try to modify module ps_emailalerts for site admin get pdf invoice also.

Add to function hookActionValidateOrder in ps_emailalerts before Mail::Send this code:

/* attach pdf patch */
$order_invoice_list = $order->getInvoicesCollection();
Hook::exec('actionPDFInvoiceRender', ['order_invoice_list' => $order_invoice_list]);
$pdf = new PDF($order_invoice_list, PDF::TEMPLATE_INVOICE, $this->context->smarty);
$attach=array();
$content = $pdf->render(false);
$attach['content'] = $content;
$attach['name'] = Configuration::get('PS_INVOICE_PREFIX', (int) $order->id_lang, null, $order->id_shop) . sprintf('%06d', $order->id) . '.pdf';
$attach['mime'] = 'application/pdf';

And modified call of Mail::Send function for attachment support:

Mail::send(
                    $mail_id_lang,
                    'new_order',
                    $this->trans(
                        'New order : #%d',
                        [
                            $order->id,                            
                        ],
                        'Emails.Subject',
                        $locale),
                    $template_vars,
                    $merchant_mail,
                    null,
                    $configuration['PS_SHOP_EMAIL'],
                    $configuration['PS_SHOP_NAME'],
                    $attach,
                    null,
                    $dir_mail,
                    false,
                    $id_shop
                );

But call of $pdf->render(false) return NULL... what could be the problem?

I have use Prestashop 1.7.8.5

$attach = array();

if (intval(Configuration::get('PS_INVOICE')) AND  $order->invoice_number)

{

$attach['content'] = PDF::invoice($order, 'S');

$attach['name'] = Configuration::get('PS_INVOICE_PREFIX', intval($order->id_lang)).sprintf('%06d', $order->invoice_number).'.pdf';

$attach['mime'] = 'application/pdf';

} else {

$attach = NULL;

}
