phpmailer - 使用 phpmailer 将 tcpdf 作为附件发送

Question

我可以生成 pdf 以便轻松查看和下载。我正在尝试发送一封附有 pdf 的电子邮件。我已经连续几天浏览谷歌了几个小时，没有什么比这个链接更让我更接近了，sending an email attachment using TCPDF 。我在链接问题上遇到了与提问者相同的问题。带有附件的电子邮件发送得很好，但 pdf 是空的，并且根据 adobe 的说法“似乎已损坏”。

共识似乎是 phpmailer 是最好的方法，所以我安装了 phpmailer 并且有以下代码。现在我收到此错误， fatal error :在第 122 行的非对象上调用成员函数 Output()。如果有人可以帮助我，我将不胜感激!

Answer 1

您可以将 PDF 存储为字符串:

$attachment = $pdf->Output('hotel4cast.pdf', 'S');

然后通过 PHPMailer 将其附加:

$mail->AddStringAttachment($attachment, 'filename.pdf', 'base64', 'application/pdf');
