【中文标题】尝试使用 html 表单中的 mail() 自动发送内联和/或附件，但不断获取二进制字符串【英文标题】：Trying to automatically send an inline and/or attachment with mail() from a html form, but keep getting binary string 【发布时间】：2012-04-11 10:48:31 【问题描述】：我正在尝试为我正在设计的俱乐部制作电子邮件表单，我希望它检查我是否在 html 电子邮件中包含附件或内联图像。到目前为止一切正常，除了当我尝试包含附件时，它会在 90 秒时超时，并且它会发送一些电子邮件，并且开头充满了“---- Content-Type: application/pdf; name= "BrainMonkey-ooPic-RS.pdf" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="test-RS.pdf" 然后是代表文件的二进制字符串，最后是 html 电子邮件当然少发附件了，代码如下：
<?php
//------------------------ Check if Subject is filled out ------------------------------>
if (isset($_POST['subject']))
//-------------- Upload File from User Computer for attachment ------------------------->
$target_path = "attachments/";
$target_path = $target_path . basename( $_FILES['file']['name']);
if(move_uploaded_file($_FILES["file"]["tmp_name"], $target_path))
$file_location = $target_path;
$fileatt = $file_location;
$fileattname =basename($file_location);
// read file into $data var
$file = fopen($fileatt, "rb");
$data = fread($file, filesize( $fileatt ) );
fclose($file);
// split the file into chunks for attaching
$content = chunk_split(base64_encode($data));
$isattached = "yes";
echo "Attachment attached ".$fileattname." uploaded and is good!";
else
$isattached = "no";
echo "No Attachment sent ".$fileattname;
//------------ Upload File from User Computer for inline image ------------------------>

我很确定问题出在标题 ($h) 上，但我不确定是什么问题。请帮忙。
提前谢谢你，

【问题讨论】：
也许你应该考虑使用 PHPMailer 或 SwiftMail。你会避免头疼的（我也会这样做，为你提供这个答案，对不起！） 我知道这会更容易，但我宁愿自己做，这样我就能确切地知道发生了什么。感谢您的建议，尽管我会调查它。 【参考方案1】：我会坚持我的旧建议使用... PHPMailer
网址：http://code.google.com/a/apache-extras.org/p/phpmailer/
下载链接：http://code.google.com/a/apache-extras.org/p/phpmailer/downloads/detail?name=PHPMailer_5.2.1.zip&can=2&q=
示例代码
$mail = new PHPMailer(true); //defaults to using php "mail()"; the true param means it will throw exceptions on errors, which we need to catch
try
$mail->AddReplyTo('name@yourdomain.com', 'First Last');
$mail->AddAddress('whoto@otherdomain.com', 'John Doe');
$mail->SetFrom('name@yourdomain.com', 'First Last');
$mail->AddReplyTo('name@yourdomain.com', 'First Last');
$mail->Subject = 'PHPMailer Test Subject via mail(), advanced';
$mail->AltBody = 'To view the message, please use an HTML compatible email viewer!'; // optional - MsgHTML will create an alternate automatically
$mail->MsgHTML(file_get_contents('contents.html'));
$mail->AddAttachment('images/phpmailer.gif'); // attachment
$mail->AddAttachment('images/phpmailer_mini.gif'); // attachment
$mail->Send();
echo "Message Sent OK</p>\n";
catch (phpmailerException $e)
echo $e->errorMessage(); //Pretty error messages from PHPMailer
catch (Exception $e)
echo $e->getMessage(); //Boring error messages from anything else!
测试了这段代码 20 次，它工作得非常好......
谢谢 :)
=============== 丢弃旧消息 ============
你有一些关键标题丢失的例子：
$h.= "Content-Type: multipart/mixed; boundary=\"".$mime_boundary."\"\r\n\r\n";
您的某些标题格式也不正确，我建议您使用 PHPMailer，如果您想要一个简单的发送邮件功能，您可以在下面使用这个...（不包括验证）
【讨论】：
没有用，只有一个主题的黑色电子邮件，或者当我尝试使用附件时附件已损坏。 @RonertH .. 请使用更新后的代码 .. 效果很好.. 试了 20 次【参考方案2】：好吧，我得到了它，当然标题完全错误，谢谢大家的帮助。万一有人需要，这里是新的 header 和 mail() 部分！
//Setup Headers
if ($isattached == "yes")
$ext = strrchr( $fileatt , '.');
$ftype = "";
if ($ext == ".doc") $ftype = "application/msword";
if ($ext == ".jpg") $ftype = "image/jpeg";
if ($ext == ".gif") $ftype = "image/gif";
if ($ext == ".png") $ftype = "image/png";
if ($ext == ".zip") $ftype = "application/zip";
if ($ext == ".pdf") $ftype = "application/pdf";
if ($ftype=="") $ftype = "application/octet-stream";
// read file into $data var
$file = fopen($fileatt, "rb");
$data = fread($file, filesize( $fileatt ) );
fclose($file);
// split the file into chunks for attaching
$content = chunk_split(base64_encode($data));
$rand = md5( time() );
$mime_boundary = '==Multipart_Boundary_' . $rand;
$h = "From: $name<$from>" . "\n";
$h .="Reply-To: $from"."\n";
$h .= "Return-Path: $from" . "\n"
."MIME-Version: 1.0\n" .
"Content-Type: multipart/mixed; boundary=\"" . $mime_boundary . "\""
."\n\n";
$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" .
$body . "\n\n";
if ($content)
$message .= "--" . $mime_boundary . "\n" .
"Content-Type: \"" . $ftype . "\";\n" .
" name=\"" . basename($fileatt) . "\"\n" .
"Content-Disposition: attachment;\n" .
" filename=\"" . basename($fileatt) . "\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$content . "\n\n" .
"--" . $mime_boundary . "--\n";
// send mail
$sent = mail($to, $subject, $message, $h);
$count++;
if ($sent)
echo "<div class=\"box green\"><center>$count Emails Sent.</center></div>";
else
echo "<div class=\"box red\"><center>$count Emails Sent.</center></div>";
再次感谢您的帮助！
