如何使用PHP發送帶有附件的電子郵件？

Question

我正在使用以下代碼發送帶有附件的電子郵件，但正確的文件未隨郵件一起附件。

$UnidID = $_COOKIE['UniqueID'];
$guid = $_COOKIE['guid'];
$target_path = "userdata/".$UniqueID."/".$iGuid."/Outputs";
$fname = getpathmail($UnidID,$guid);
$target_path = $target_path.$filname;

$fileatt_type = "application/fbf"; // File Type
$fileatt_name = $fname; 
$data = $target_path;
$email_from = "EHPAdmin@fugro.in"; 
$email_subject = "EHP/PPP process";
$email_message = "Processed result for EHP/PPP processing";

$email_to = $_GET['Email'] ; 

$headers = "From: ".$email_from;

$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";

$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$email_message .= "\n\n";

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

$email_message .= "--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data .= "\n\n" .
"--{$mime_boundary}--\n";

$ok = @mail($email_to, $email_subject, $email_message, $headers);

Answer 1

我建議使用一個庫來發送電子郵件，因為它將處理所有與標頭相關的內容。 看看Zend_Mail 。 發送附件就像

$mail = new Zend_Mail();

$at = $mail->createAttachment($myImage);
$at->type        = 'image/gif';
$at->disposition = Zend_Mime::DISPOSITION_INLINE;
$at->encoding    = Zend_Mime::ENCODING_8BIT;
$at->filename    = 'test.gif';

$mail->send();

Answer 2

您需要將所有多部分郵件放入$email_message ：

$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

$headers = "From: ".$email_from;
$headers .= "\nMIME-Version: 1.0\n" .
"Content-Type: multipart/mixed;\n" .
" boundary=\"{$mime_boundary}\"";

$email_message .= "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type:text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
"--{$mime_boundary}\n" .
"Content-Type: {$fileatt_type};\n" .
" name=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
chunk_split(base64_encode($data)) .
"--{$mime_boundary}--\n";

Answer 3

可能是您在代碼中錯過了這個

 ...

 $file = fopen($data,'rb');
 //saves content in $data itself
 $data = fread($file,filesize($data));
 fclose($file); 

 ...

應該工作沒有執行自己。 試試看

您應將附件文件指定為：

"Content-Disposition: attachment; filename='/path/to/the/file/filename'";
