如何在magento 2中附加发票PDF而不是装箱单

Question

我想在创建货件时附上发票 pdf 而不是装箱单。 我正在使用 Fooman 电子邮件附件扩展版本 2.0.8

我的 magento 是 2.2.5 有人知道如何更改发货确认邮件中随附的 PDF 吗？

目前它正在附上装箱单，但我想在发货确认邮件中附上发票 pdf。

Answer 1

我们在使用 fooman 时遇到了类似的问题。我们还希望在创建发货时发送我们的发票，同时在创建发票时禁用标准交易发票邮件。我编写了一个模块，将发票电子邮件与发货电子邮件一起发送，这并不是您正在寻找的，但也许您可以利用它。

该模块非常简单。除了样板的registration.php和module.xml，你只需要覆盖Magento\Sales\Model中的InvoiceOrder并注释掉这一行：

$this->notifierInterface->notify($order, $invoice, $comment);

像这样：

        }
        return $invoice->getEntityId();
    }
}

现在你要做的就是设置events.xml并观察sales_order_shipment_save_after

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name='sales_order_shipment_save_after'>
        <observer name='SendInvoiceWithShipment' instance='Vendor\Module\Observer\SendInvoiceWithShipment'
        />
    </event>
</config>

Observer 像这样利用标准 Magento 2 交易电子邮件 $this->_invoiceSender->send($invoice);：

<?php

namespace Vendor\Module\Observer;

use Magento\Framework\Event\ObserverInterface;
use Magento\Sales\Model\Order;
use Magento\Sales\Model\Order\Email\Sender\InvoiceSender;

class SendInvoiceWithShipment implements ObserverInterface
{
    protected $_invoiceSender;

    public function __construct(
        InvoiceSender $invoiceSender
    ) {
        $this->_invoiceSender = $invoiceSender;
    }

    public function execute(\Magento\Framework\Event\Observer $observer)
    {
        $order = $observer->getShipment()->getOrder();
        if (!$order) {
            // Dont send invoice if order is not provided 
            return; 
        }

        $invoices = $order->getInvoiceCollection();

        foreach ($invoices as $invoice) {

                try {
                    $this->_invoiceSender->send($invoice);
                } catch (\Exception $e) {
                    // Do something if failed to send                          
                }

        }               

        
    }
}
