How to best add features into core files

[Kristian Toldy]

Hi,

I'm new to PrestaShop and I'm not sure how to do this the best.

We're trying to add 2 specific PDF files to the order confirmation email. We have a working code which adds these files and is working correctly by putting it in the classes/Mail.php file:

           if ($template == 'order_conf'){
             $file = _PS_ROOT_DIR_ . '/terms.pdf';
             $message->attach(Swift_Attachment::fromPath($file));
             $file2 = _PS_ROOT_DIR_ . '/return_money.pdf';
             $message->attach(Swift_Attachment::fromPath($file2));
            }

This is however a temporary solution as whenever Prestashop would get upgraded, this code would disappear as being part of a core. How else could this be done so it's protected from updating and the attachments are properly included in the send function.

Thanks for any tips!

You can do this by override: https://devdocs.prestashop.com/1.7/modules/concepts/overrides/

Thanks, we did override it by copying the  send function into an override class but this does not help with the updating problem as we copied the whole function. What if in the future there is an update to this function, because the overridden function will be always in use it won't be updated.

Thanks

There is no easy way if you want to do this by changes in core file, the best solution is creating own module and send email from it.

We suggest to use ActionEmailAddAfterContent hook to modify the email content.

  For reference:   

    public function hookActionEmailAddAfterContent(&$params)
    {
        $content = '';
        if ($params['template'] == 'order_conf') {

         // Let's edit content of Order's Confirmation email
   
            $params['template_html'] = str_replace("order", "order_new" . $content, $params['template_html']); 
        }
    }
