我有一个在线PDF表单，用户完成该表单，然后单击提交按钮，该按钮将表单作为附件发送到电子邮件地址，并将数据存储在数据库中。但是，当发送到电子邮件地址时，不会显示已完成的单个字段值。我怎样才能做到这一点？非常感谢。
//define the receiver of the email
$to = 'test@*****.com';
//define the subject of the email
$subject = 'Completed PDF form';
//create a boundary string. It must be unique
//so we use the MD5 algorithm to generate a random hash
$random_hash = md5(date('r', time()));
//define the headers we want passed. Note that they are separated with 'r'n
$headers = "From: noreply@test.com'r'nReply-To: noreply@test.com";
//add boundary string and mime type specification
$headers .= "'r'nContent-Type: multipart/mixed; boundary='"PHP-mixed-".$random_hash."'"";
//read the atachment file contents into a string,
//encode it with MIME base64,
//and split it into smaller chunks
$attachment = chunk_split(base64_encode(file_get_contents('purchase_order_form.pdf')));
//define the body of the message.
ob_start(); //Turn on output buffering
?>
--PHP-mixed-<?php echo $random_hash; ?>
Content-Type: multipart/alternative; boundary="PHP-alt-<?php echo $random_hash; ?>"
--PHP-alt-<?php echo $random_hash; ?>

Hello World!!!
This is simple text email message.
--PHP-alt-<?php echo $random_hash; ?>
Content-Type: text/html; charset="iso-8859-1"
Content-Transfer-Encoding: 7bit
--PHP-alt-<?php echo $random_hash; ?>--
--PHP-mixed-<?php echo $random_hash; ?>
Content-Type: application/zip; name="purchase_order_form.pdf"
Content-Transfer-Encoding: base64
Content-Disposition: attachment
<?php echo $attachment; ?>
--PHP-mixed-<?php echo $random_hash; ?>--
<?php
//copy current buffer contents into $message variable and delete current output buffer
$message = ob_get_clean();
//send the email
$mail_sent = @mail( $to, $subject, $message, $headers );
//if the message is sent successfully print "Mail sent". Otherwise print "Mail failed"
echo $mail_sent ? "Mail sent" : "Mail failed";
下面是您使用Swiftmailer的示例，您会发现它真的更容易！
require_once '/path/to/swift-mailer/lib/swift_required.php';
// Create the Transport
$transport = Swift_MailTransport::newInstance();
// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
// Create the message
$message = Swift_Message::newInstance()
// Give the message a subject
->setSubject($subject)
// Set the From address with an associative array
->setFrom(array('noreply@test.com'))
// Set the To addresses with an associative array
->setTo(array($to))
// Give it a body
->setBody($message)
// Optionally add any attachments
->attach(Swift_Attachment::fromPath('purchase_order_form.pdf'))
;
// Send the message
$result = $mailer->send($message);
echo $mail_sent ? "Mail sent" : "Mail failed";
