mPDF自动生成的PDF邮件发送空白电子邮件 [英] mPDF Auto Generated PDF Mailer sends blank Email

问题描述

我正在使用mPDF类，我可以成功地使用以下代码生成一封电子邮件。但是，我的电子邮件是空白的。我假设，但不知道这是否与我的标题有关。我很难说，因为我收到我的电子邮件，但不能打开它产生的pdf。

I am using mPDF class and am successfully able to generate an email with the following code. However, my email comes out blank. I am assuming but am not sure if this has something to do with my headers. It's hard for me to tell because I am getting my emails but am not able open the pdf it generates.

         include("./mpdf.php");

         $mpdf->debug = true;

         $html2 = '
              <div style="margin-left:3%;">Attach additional photos: 
              <input type="file" name="file" id="file" /></div><hr />';

         echo $html2;



         if ( isset( $_POST['submit'] ) ) {
         $file_path = "webform.php";
         $file_path_type = "application/pdf";
              $mpdf=new mPDF('iso-8859-2');
              $mpdf->WriteHTML($html);

         $file_path_name = "eval.pdf"; 
         $headers .= 'Content-type: text/html; charset=utf-8' . "\n"; 
         $from = "[e-mail]";
         $to = $_POST['email'];
         $ccto = $_POST['youremail'];
         $subject = "New Form Submitted"; 
         $message = "*** This is an automatically generated email, 
                   please do not reply *** Someone in your association 
                   has completed a survey.

         $headers = "From: ".$from;
         $headers.= "cc: " . $ccto . " <" . $ccto . ">" . "\n" ;
         $file = fopen($file_path,'rb');
         $data = fread($file,$file_path);
         fclose($file); 

         $rand = md5(time());
         $mime_boundary = "==Multipart_Boundary_x{$rand}x"; 

         $headers .= "\nMIME-Version: 1.0\n" .
         "Content-Type: multipart/mixed;\n" .
         " boundary=\"{$mime_boundary}\""; 

         $message .= "This is a multi-part message in MIME format.\n\n" .
         "--{$mime_boundary}\n" .
         "Content-Type:text/html; charset=\"iso-8859-1\"\n" .
         "Content-Transfer-Encoding: 7bit\n\n" .
         $message .= "\n\n"; 


         $data = chunk_split(base64_encode($data)); 

        $message .= "--{$mime_boundary}\n" .
          "Content-Type: {$file_path_type};\n" .
          " name=\"{$file_path_name}\"\n" .
          "Content-Disposition: attachment;\n" .
          " filename=\"{$file_path_name}\"\n" .
          "Content-Transfer-Encoding: base64\n" .
        $data .= "\n\n" .
          "--{$mime_boundary}--\n";  

        if(@mail($to, $subject, $message, $headers)) {
        echo '<script language="javascript">';
        echo 'alert("Document sent successfully!")';
        echo '</script>';
        echo "Sent!";

        } else {
        echo 'Failed';
        }
        }
        exit;

推荐答案

你正在学习困难 - 不要调用 mail（）你自己，因为你会做错了;构建和发送电子邮件是非常复杂的，充满了陷阱，正如你所发现的那样。使用图书馆，无论是 PHPMailer ，SwiftMailer Zend_Mail等，它将为您节省大量的麻烦。您还需要分别检查您的两个操作 - 首先创建一个PDF，将其写入文件并确保其正常工作;然后写一些发送消息的代码，并检查是否有效;然后让它发送PDF。否则，如果你发现它不工作，你将无法知道哪一部分是坏的。

You're learning the hard way - Don't call mail() yourself because you will do it wrong; constructing and sending email messages is horribly complicated and full of pitfalls, as you're finding. Use a library, whether PHPMailer, SwiftMailer Zend_Mail etc, to do it and it will save you a great deal of hassle. You also need to check your two operations separately - first create a PDF, write it to a file and make sure it works correctly; Then write some code that sends a message and check that works; Then get it to send the PDF. Otherwise if you find it's not working, you won't be able to tell which part is broken.
