PHP-无法从表单发送带有附件的电子邮件

Question

I having some trouble sending e-mail with attachment from the php MAIL function. The error checking is working but I can't get the file to upload and send in the e-mail. I'm using code I've pulled off the net. Just can't seem to get it working. Anyone have any thoughts? Any help would be appreciated. Thanks! URL to follow:

Answer 1

我使用PHPMAILER，它易于使用，有很多示例（包括附加文件的方法） pagina de phpmailer

Answer 2

• You need to remove the \\r's and replace them with \\n's. Most mailservers no longer accept \\r

• You need random hash separators for the MIME (see below code for example)

  $filename = "MyAttachment.pdf";

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

  $separator = md5(time());

  // carriage return type (we use a PHP end of line constant)

  $eol =PHP_EOL;

  // main header

  $headers = "From: ".$from.$eol;

  $headers .= "MIME-Version: 1.0".$eol; $headers .= "Content-Type: multipart/mixed; boundary=\\"".$separator."\\"";

  // no more headers after this, we start the body! //

  $body = "--".$separator.$eol;

  $body .= "Content-Transfer-Encoding: 7bit".$eol.$eol;

  $body .= "This is a MIME encoded message.".$eol;

  // message $body .= "--".$separator.$eol;

  $body .= "Content-Type: text/html; charset=\\"iso-8859-1\\"".$eol;

  $body .= "Content-Transfer-Encoding: 8bit".$eol.$eol;

  $body .= $message.$eol;

  // attachment

  $body .= "--".$separator.$eol;

  $body .= "Content-Type: application/octet-stream; name=\\"".$filename."\\"".$eol;

  $body .= "Content-Transfer-Encoding: base64".$eol;

  $body .= "Content-Disposition: attachment".$eol.$eol;

  $body .= $attachment.$eol;

  $body .= "--".$separator."--";

  // send message

  mail($to, $subject, $body, $headers);

or you can just download the 3 class files from PHPmailer as suggested above since it has all of this already finished for you.
