PHP多附件电子邮件显示为文本

您得到了错误的标头。这是"内容处置"，而不是"内容描述"。尝试：

Content-Disposition: attachment; filename="html.login.php"

相反。内容描述是添加一个简短的附件描述，例如"这是我的简历"，与告诉邮件客户端如何处理附件无关。

我知道这是一个已经解决的问题，但我想为未来可能需要它的所有人发布一个工作函数。网络上有很多发送多附件电子邮件的例子，但大多数都令人困惑且不起作用。我有turibe功能(我希望你不要介意(，并进行了一点修改。

我使用一个共享主机，但还不知道如何使用PEAR邮件功能-我读到的所有内容似乎都认为读者已经知道如何将PEAR与include('mail.php'(结合在一起-但没有人说如何获得mail.php文件。呃。

无论如何，我的应用程序很少发送电子邮件，一次只发送给少数收件人。所以我觉得使用php的邮件实用程序是很好的。

此外，有时我的附件是动态生成的，所以我把chunk_split放在方法之外，这样我就可以很容易地附加一个实际的文件，或者同样容易地生成数据并将其作为文件附加。

下面是一个经过实际测试的简单电子邮件类：

    $mime_types = array("pdf"=>"application/pdf","zip"=>"application/zip","csv"=>"text/plain","doc"=>"application/msword"

*-用法：*

$mail = new MyMail;  
$mail->setSubject( ' Testing 123 Subject' );
$mail->setFrom( 'me <testFrom@abc.com>' ); 
$mail->setTo( 'Anne Test <atest@example.com>' );
$mail->setCc('Jeff Test <jtest@example.com>, Mary Test <mtest@example.com>');
$mail->setMessage( "<h1>This is a test</h1>'n'n<p>This is a para</p>" ); // note the nl added in case mail opens as pure text...
// dynamically produced file data  
$mail->setAttachment( $fileName1,  
    chunk_split(base64_encode($attachmentData1)) );  
// attach actual file  
$mail->setAttachment( $fileName2,  
    chunk_split(base64_encode(file_get_contents('testFile.pdf'))) );   
echo ( $mail->send() ) ? 'sent' : 'oops';
