php - 使用 PHP 发送带有 PDF 文件附件的电子邮件

Question

好的，这是我的第一个主题，我在网上搜索过但没有找到。我正在实习，我正在做一个项目，该项目要求我创建一个网页，在用户提交他/她的信息时生成一个 pdf 文件。一旦客户点击提交按钮，就需要发生 3 件事:

1. 将信息存储到数据库(完成)，
2. 向员工发送包含新客户信息的电子邮件(完成)，以及
3. 向客户发送带有 pdf 文件附件的“感谢信息”电子邮件(无效)。

我的意思是，客户确实收到了一封电子邮件，但是当他/她打开 pdf 文件时，我收到以下错误消息:

"Acrobat could not oen 'file_name' because it is either not a supported file type or because the file has been damaged(for example, it was sent as an email attachment and wasn't correctly decoded)..."

请记住，这是我第一次做有关创建 pdf 文件附件的项目。如果有人可以帮助我解决这个问题，那就太好了。谢谢!

这是我的代码:

<?php
// once there are no errors, as soon as the customer hits the submit button, it needs to send an email to the staff with the customer information
        $msg = "Name: " .$_POST['name'] . "\n"
            ."Email: " .$_POST['email'] . "\n"
            ."Phone: " .$_POST['telephone'] . "\n"
            ."Number Of Guests: " .$_POST['numberOfGuests'] . "\n"
            ."Date Of Reunion: " .$_POST['date'];
        $staffEmail = "staffinfo";

        mail($staffEmail, "You have a new customer", $msg); // using the mail php function to send the email. mail(to, subject line, message)

        //once the customer submits his/her information, he/she will receive a thank you message attach with a pdf file.
        $pdf=new FPDF();
        $pdf->AddPage();
        $pdf->SetFont("Arial", "B", 16);
        $pdf->Cell(40, 10, "Hello World!");

        // email information
        $to = $_POST['email'];
        $from = $staffEmail;
        $subject = "Thank you for your business";
        $message = "Thank you for submitting your information!";

        // a random hash will be necessary to send mixed content
        $separator = md5(time());

        // carriage return type (we use a PHP end of line constant)
        $eol = PHP_EOL;

        // attachment name
        $filename = "yourinformation.pdf";

        // encode data (puts attachment in proper format)
        $pdfdoc = $pdf->Output("", "S");
        $attachment = chunk_split(base64_encode($pdfdoc));

        // encode data (multipart mandatory)
        $headers = "From: ".$from.$eol;
        $headers .= "MIME-Version: 1.0".$eol;
        $headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol.$eol;
        $headers .= "Content-Transfer-Enconding: 7bit".$eol;
        $headers .= "This is a MIME encoded message.".$eol.$eol;

        // message
        $headers .= "--".$separator.$eol;
        $headers .= "Content-Type: text/html; charsrt=\"iso-8859-1\"".$eol;
        $headers .= $message.$eol.$eol;

        $headers .= "Content-Disposition: attachment".$eol.$eol;
        $headers .= $attachment.$eol.$eol;
        $headers .= "--".$separator."--";

        // send message
        mail($to, $subject, $message, $headers);
