我正在做一个应用程序，它有一个带有三个文件输入的联系表单...当我发送电子邮件时，根本不显示文件，简单地显示一个大的编码文本。我做错了什么？谢谢＆＃39; S。这是我的功能（处理电子邮件的代码的一部分。
function send_mail() {
$to = "me@me.com";
$fromEmail = $_POST['email'];
$fromName = $_POST['first_name'];
$subject = 'mail web';
/* Encoding file message_data */
$message_data = chunk_split(base64_encode($message_data));
$file_Name = $_FILES['fileToUpload']['tmp_name'];
$file_Type = $_FILES['fileToUpload']['type'];
$file_tmp_Name = $_FILES['fileToUpload']['name'];
/* a boundary string */
$randomVal = md5(time());
$mimeBoundary = "==Multipart_Boundary_x{$randomVal}x";
/* Header for File Attachment */
$headers .= "\nMIME-Version: 1.0\n";
$headers .= "Content-Type: multipart/mixed;\n" ;
$headers .= " boundary=\"{$mimeBoundary}\"";
/* Multipart Boundary above message */
$message = "This is a multi-part message in MIME format.\n\n" .
"--{$mimeBoundary}\n" .
"Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$message . "\n\n";
for($x=0;$x<3;$x++){
$tmpName = $file_Name[$x];
$fileType = $file_Type[$x];
$fileName = $file_tmp_Name[$x];
if (isset($tmpName)) {
$file = fopen($tmpName,'rb');
$msg_data = fread($file,filesize($tmpName));
fclose($file);
/* Encoding file msg_data */
$msg_data = chunk_split(base64_encode($msg_data));
/* Adding attchment-file to message*/
$message .= "--{$mimeBoundary}\n" .
"Content-Type: {$fileType};\n" .
" name=\"{$fileName}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$msg_data . "\n\n" .
"--{$mimeBoundary}--\n";
}
}
$ok = @mail($to, $subject, $message, $headers);
if ($ok) {
echo "<p>mail sent to $to!</p>";
} else {
echo "<p>mail could not be sent!</p>";
}
} //end function
