Attachments

Files are attached when calling from code: the reserved attachments key in $data is a list of paths on the server. It does not become a placeholder.

$modx->services->get('Vestnik')->trigger('shop.order.new', [
    'email'       => $order->get('email'),
    'order_id'    => $order->get('id'),
    'attachments' => [
        MODX_CORE_PATH . 'components/vestnik/attachments/invoice-105.pdf',                    // path
        ['file' => MODX_CORE_PATH . 'components/vestnik/attachments/terms.pdf', 'name' => 'Terms.pdf'], // path + name in the email
    ],
], 'component');

• The queue stores the path, not the contents: the file must exist when cron sends the email.
• Only files from the vestnik_attachments_path folder can be attached (empty — core/components/vestnik/attachments/). The MODX configuration, PHP files and hidden files can never be attached.
• A file outside the folder or a missing file is a sending error; the email goes to retries and the reason is shown in the queue and log.
• Attachments are added to every email of this trigger() call.
• The vestnik_notify snippet does not pass attachments.
