MPDF电子邮件附件发送空白PDF [英] MPDF E-mail Attachment Sends Blank PDF

问题描述

我已成功使用mpdf生成了PDF，并已通过下载PDF进行了验证.但是，当我将PDF作为电子邮件附件发送时，我收到了一个空白的PDF，Adobe Reader出现了内存不足"错误.下面是我的代码:

I have successfully generated a PDF using mpdf, which I have verified by downloading the PDF. However, when I send the PDF as an e-mail attachment I receive a blank PDF with an "Out of Memory" error by Adobe Reader. Below is my code:

<?php

include("MPDF57/mpdf.php");

ob_start();
include "Receipt_Template_2.php"; 
$template = ob_get_contents();
ob_end_clean();

$mpdf=new mPDF('','A4','','',32,25,27,25,16,13,'L'); 

mpdf->WriteHTML($template);

$content = $mpdf->Output($template, 'S');

$content = chunk_split(base64_encode($content));
$mailto = '[e-mail]';
$from_name = 'KIREA';
$from_mail = '[e-mail]';
$uid = md5(uniqid(time()));
$subject = 'KIREA Donation Receipt';
$message = "Thank you for your donation!\n\nAttached is the receipt concerning the     donation. If you have any questions, please e-mail us at [e-mail]";;
$filename = $pdfName;

$header = "From: ".$from_name." <".$from_mail.">\n";
$header .= "MIME-Version: 1.0\n";
$header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\n";
$header .= "This is a multi-part message in MIME format.\n";
$header .= "--".$uid."\r\n";
$header .= "Content-type:text/plain; charset=iso-8859-1\n";
$header .= "Content-Transfer-Encoding: 7bit\n";
$header .= $message."\n\r\n";
$header .= "--".$uid."\n";
$header .= "Content-Type: application/pdf; name=\"".$filename."\"\n";
$header .= "Content-Transfer-Encoding: base64\n";
$header .= "Content-Disposition: attachment; filename=\"".$filename."\"\n\n";
$header .= $content."\n\n";
$header .= "--".$uid."--";

$is_sent = @mail($mailto, $subject, "", $header);

$mpdf->Output();
exit;

?>

对于作为电子邮件附件发送后，为什么PDF最终空白的问题，是否有任何想法?谢谢.

Are there any ideas as to why the PDF is ending up blank after being sent as an e-mail attachment? Thank you.

推荐答案

mpdf->WriteHTML($template);
$content = $mpdf->Output($template, 'S');

您在这里错了，您没有拿到写有数据的对象

You are wrong at here you are not taking the object on which your data is written

请用下面的代码替换上面的代码，以得到正确的结果.

please replace below code with above to get correct result.

$pdfdata=mpdf->WriteHTML($template);
$content = $mpdf->Output('' , 'S');

在电子邮件中使用$content
