Question

尝试附加pdf文件时，无法以PDF格式打开并说明其已损坏。我尝试了在网络上找到的几种解决方案，但它没有用。该文件正在附加和发送，但是当您打开PDF时它已损坏虽然正在下载但是尺寸无效（1kb），其中原始大小约为0.40mb

非常感谢任何帮助。

function mail_attachment($filename, $path, $mailto, $from_mail, $from_name, $replyto, $subject, $message)
{


$separator = md5(time());

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




//$pdfdoc is PDF generated by FPDF

$attachment = chunk_split(base64_encode($pdfdoc));

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

// 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."--";

// send message
if (mail($mailto, $subject, $body, $headers)) {
    echo "mail send ... OK";
} else {
    echo "mail send ... ERROR";
}

编辑＃1：在自己做了一些研究之后，我发现使用外部库来设置带附件的电子邮件要容易得多。我使用PHPMailer完成了这项工作，可以从https://github.com/Synchro/PHPMailer下载。

以下代码应该可以满足您的需求。我强烈建议使用PHPMailer等库。

// File to attach
$filename = "outsource.pdf";
$path = $_SERVER['DOCUMENT_ROOT']. "/wp-content/uploads/2014/02/";

// Who email is FROM
$from_name   = "COmpany Name";
$from_mail    = "company@domain.com";
$replyto = "company@domain.com";

// Whe email is going TO
$mailto   = $_POST['Field3']; 

// Subject line of email
$subject = "Your file has arrived!";

// Content of email message (Text only)
$requester   = $_POST['Field12'];  // Comes from Wufoo WebHook
$message     = "Hey $requester,

Your custom email message
goes here";


/*
* The following code requires PHPMailer
*/
require_once('PHPMailer-master/class.phpmailer.php');

$mail = new PHPMailer();
$mail->AddReplyTo($replyto, $from_name);
$mail->SetFrom($from_mail, $from_name);
$mail->AddAddress($mailto, $requester);
$mail->Subject = $subject;
$mail->MsgHTML($message);
$mail->AddAttachment($path . $filename);

if (!$mail->Send()) {
    echo "Mail error!";
} else {
    echo "Mail success!";
}

您似乎使用以下代码覆盖PDF文件：

$str = "Business Plan: \nSome more text";
$fp = fopen("outsource.pdf", 'w+');
fwrite($fp, $str);
fclose($fp);

w+中的fopen()选项会创建一个新的空白文件。您似乎想要发送原始文件，在这种情况下您不需要这些代码行。你想在这里完成什么？

PDF文件不会附加返回0字节损坏的文件
