如何在 Magento2 中以发票 pdf 格式添加 'echo' 的简单消息？
How to add a simple message by 'echo' in invoice pdf format in Magento2?
我已经从 magento2 销售订单的发票选项生成了发票单，并得到了截图以供参考，请看截图：https://prnt.sc/tje4zn
这是发票pdf的文件路径：/vendor/magento/module-sales/Model/Order/Pdf/AbstractPdf.php下面是文件代码，

我想在文件末尾回显简单的文本消息，例如 <?php echo "NOTE: This is not a GST invoice. This is a packing slip only."; ?>
请帮助我如何将此消息添加到 pdf 发票格式，正如我在上面的屏幕截图中提到的那样。
非常感谢。
假设您有一个自定义 MyCompany_Invoice 模块：

让我知道您是否需要模块工作所需的其他文件的内容，或者是否有任何不适合您的地方。
我还没有尝试更改文本颜色，因此您可能需要自己寻找解决方案。

我想在文件末尾回显简单的文本消息，例如 <?php echo "NOTE: This is not a GST invoice. This is a packing slip only."; ?>
请帮助我如何将此消息添加到 pdf 发票格式，正如我在上面的屏幕截图中提到的那样。

假设您有一个自定义 MyCompany_Invoice 模块：

<preference for="Magento\Sales\Model\Order\Pdf\Invoice" type="MyCompany\Invoice\Model\Order\Pdf\InvoicePdf"/>
</config>
现在创建 MyCompany\Invoice\Model\Order\Pdf\InvoicePdf.php:
<?php
namespace MyCompany\Invoice\Model\Order\Pdf;
use \Magento\Sales\Model\Order\Pdf\Invoice;
