PHP 附加 PDF 邮件功能

Question

我一直在尝试让 php 发送带有附件 PDF 的电子邮件，我一直在到处寻找并发现了这个帖子 Email PDF Attachment with PHP Using FPDF。

我尝试了解决方案，但仍然没有运气，有人知道我哪里出错了吗？我没有收到错误或电子邮件？

基本上，这是从表单中获取值，将它们放入数据库，然后向它们发送电子邮件。

任何帮助将不胜感激。

require('fpdf.php');
include("database.php");
require_once('recaptchalib.php');
$publickey = "6LcBYNsSAAAAAKkf5LwKkrhTVTVlxmOblcOn70-r ";

// email stuff (change data below)
$to = "brentfrench@bigwavemedia.co.uk";

$message = "<p>Please see the attachment.</p>";


// PDF Create 
$pdf = new FPDF('P', 'pt', array(500,233));
$pdf->AddPage();

Answer 1

我会将您的反垃圾邮件检查移到顶部，但我得到了下面的代码。我将您的 EOL 标记更改为“\r\n”，并在标题末尾添加了另一个 $eol。此外，我在 mail() 调用中将 $message 更改为 $body，因为 $body 的所有准备工作都已完成，但并未使用。

// 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 = "\r\n";

// attachment name
$filename = "test.txt";

// encode data (puts attachment in proper format)
$attachment = chunk_split(base64_encode("I am text file"));

// main header
$headers  = "From: ".$from.$eol;
$headers .= "MIME-Version: 1.0".$eol; 
$headers .= "Content-Type: multipart/mixed; boundary=\"".$separator."\"".$eol;

// no more headers after this, we start the body! //
$body = "--".$separator.$eol;
$body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;
$body .= "This is a MIME encoded message.".$eol;

// message
$body .= "--".$separator.$eol;
$body .= "Content-Type: text/html; charset=\"iso-8859-1\"".$eol;
$body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;
$body .= $message.$eol;

// attachment
$body .= "--".$separator.$eol;
$body .= "Content-Type: application/octet-stream; name=\"".$filename."\"".$eol; 
$body .= "Content-Transfer-Encoding: base64".$eol;
$body .= "Content-Disposition: attachment".$eol.$eol;
$body .= $attachment.$eol;
$body .= "--".$separator."--";

// form values
$firstname = $_POST['first'];
$lastname = $_POST['last'];
$postcode = md5($_POST['post']);
$email = $_POST['email'];


echo mail($to, $subject, $body, $headers) or die("Mail Error");                   
echo "<p>Voucher has been emailed, we looked foward to seeing you soon</p>\n";

Answer 2

我写了一个邮件类。附件代码如下：

$body .= "--".$separator."\r\n";
$body .= "Content-Disposition: attachment; filename=\"".$filename."\";\r\n";
$body .= "Content-Length: ".$filesize.";\r\n";
$body .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n";
$body .= "Content-Transfer-Encoding: base64\r\n\r\n";
$body .= $attachment."\r\n";
$body .= "--".$separator."--";

您会发现一些不同之处：我将 Content-Length、2x $filename 和 \r\n 作为 EOL。

我希望这会有所帮助。

这段代码中有很多可能的断点，无法准确判断出了什么问题。您需要自己进行一些调试，例如。使用测试输出，看看脚本能走多远。还要确保激活错误报告。

发送附件更简单的方法可能是使用SwiftMailer library.
