PHP mail（） - 一旦添加文件附件，HTML将作为附件显示

Question

终于得到了所有的错误，现在他们说：“哦，我们需要添加附件......”所以，这个发送一个纯文本版本的html邮件，并且只是在膨胀。现在我有附件到达邮件客户端显示纯文本版本内联和html版本作为另一个附件，然后看似空的93字节文件名称像ATT00248.txt。

任何人都可以从后面打我的头或告诉我我要去哪里错了吗？我希望在邮件用户界面中可用的HTML内联，HTML不可用的纯文本版本以及单个附件作为附件。

任何帮助？

佩卡说得对 - 这是简单而强大的使用Swiftmailer。 http://swiftmailer.org

Answer 2

我会张贴此评论，但它太长。

// #1 // 
if ($to = $_SESSION['recipients'][0]) { 
    mail($to, $subject, $body, 
    "From: " . $from . "\n" . 
    "MIME-Version: 1.0\n" . 
    "Content-Type: multipart/$mailtype;\n" . 
    "  boundary=" . $mime_boundary_header); 

    echo "Email sent to " . htmlentities($to) . ".<br />"; 
} 


// #2 ... #3 ... #4 ... #5 

将最终执行所有块，因为($to = $_SESSION['recipients'][0])将始终为真。即使mail()失败，它也会显示“发送给...的电子邮件”。

你想要的是：

if (in_array($to, $_SESSION['recipients'])) { 
    if (mail($to, $subject, $body, 
    "From: " . $from . "\n" . 
    "MIME-Version: 1.0\n" . 
    "Content-Type: multipart/$mailtype;\n" . 
    "  boundary=" . $mime_boundary_header)) { 
     echo "Email sent to " . htmlentities($to) . ".<br />"; 
    } 
} 

或者，如果你真的想大家邮寄或

foreach ($_SESSION['recipients'] as $to) { 
    if (mail($to, $subject, $body, 
    "From: " . $from . "\n" . 
    "MIME-Version: 1.0\n" . 
    "Content-Type: multipart/$mailtype;\n" . 
    "  boundary=" . $mime_boundary_header)) { 
     echo "Email sent to " . htmlentities($to) . ".<br />"; 
    } 
}
