使用TCPDF发送电子邮件附件

Question

PHP我有一个简单的课程申请表,填写完成后,会向申请人发送一封电子邮件,并附上他选择作为pdf附件的课程的费用报价.

我正在使用TCPDF并使用会话变量将数据从表单传递到库.内容采用html格式.

生成PDF并根据需要作为附件发送.问题是它是空白的..只有页眉和页脚在文档中.在linux中尤其如此.在Windows中,pdf文档在下载时按预期生成.但是,在下载文档之前单击"视图"时,只显示页眉和页脚.

这是我的代码.请有人帮忙.谢谢.

<?php

Answer 1

你可以这样做:

$fileatt = $pdf->Output('quotation.pdf', 'E');

选项E:将文档作为base64 mime多部分电子邮件附件(RFC 2045)返回,我发现此信息:tcpdf文档

之后你只需要这样做:

$data = chunk_split($fileatt);

并且您的文件已准备好附加到邮件,无需使用文件.只需保留标题和其他设置即可完成工作.

要么

2.您可以使用F将其保存在服务器上,然后获取如下数据:

$filename = location_on_server."quotation.pdf";

$fileatt = $pdf->Output($filename, 'F');

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

Answer 2

Output($name='yourfilename.pdf', $dest='E')

E是你解决的问题的解决方案.这是$ dest字符串(Destination发送文档的位置)的可能值的lisst:

• I:将文件内联发送到浏览器(默认).
• D:发送到浏览器并强制使用名称给出的名称下载文件.
• F:保存到名称为name的名称的本地服务器文件.
• S:将文档作为字符串返回(名称被忽略).
• FI:相当于F + I选项
• FD:相当于F + D选项
• E:将文档作为base64 mime多部分电子邮件附件(RFC 2045)返回

Answer 3

我尝试了很多选择.有效的是当我使用tcpdf输出设置"F"设置保存到文件夹时.包含phpmailer文件并使用下面的代码.

$pdf->Output("folder/filename.pdf", "F"); //save the pdf to a folder setting `F`
require_once('phpmailer/class.phpmailer.php'); //where your phpmailer folder is
$mail = new PHPMailer();                    
$mail->From = "email.com";
$mail->FromName = "Your name";
$mail->AddAddress("email@yahoo.com");
$mail->AddReplyTo("email@gmail.com", "Your name");               
$mail->AddAttachment("folder/filename.pdf");      
// attach pdf that was saved in a folder
$mail->Subject = "Email Subject";                  
$mail->Body = "Email Body";
if(!$mail->Send())
{
   echo "Message could not be sent. <p>";
   echo "Mailer Error: " . $mail->ErrorInfo;
}
else
{
   echo "Message sent";
} //`the end`
