附加文件时，PHP不发送邮件

我已经搜索了这个网站，但我找不到与此相关的东西。如果有，请指给我看

我的php分为两个部分，一个是在没有附件的情况下发送邮件（工作正常）

下一个应该附加文件并将其与$msg一起发送。然而，这是行不通的。我将在这里包括完整的发送邮件php

我有一个想法，它与$FILES和$POST有关，但无法正确执行

您的代码有语法错误：

 if(!isset($_SERVER['HTTP_X_REQUESTED_WITH']) AND strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) != 'xmlhttprequest') {
        $output = json_encode(array( //create JSON data
            'type'=>'error',
            'text' => 'Sorry Request must be Ajax POST'
        ));
        die($output); //exit script outputting json data
    }

---

请参阅输出数组中的“behind POST”。

您的代码中有错误，堆栈的语法高亮显示显示了这一点，我无法发现它。现在，您的表单是否包含正确的enctype？你的表单没有发布。这很奇怪，我在dreamweaver中没有发现任何语法错误。我将根据您的编辑编辑文章并添加重新列表，我没有看到任何表单标签。它需要有一个post方法和附加文件时需要的

enctype=“multipart/form data”

。您指的是$headers。=“内容类型：multipart/mixed；boundary=“.md5（'boundary1'）。”\r\n\r\n”；$headers.=“--”.md5（'boundary1'）。“\r\n”；$headers.=“内容类型：多部分/可选；边界=“.md5（'boundary2'）。”\r\n\r\n”<代码>东西在哪里？谢谢，我在那里添加了，但它仍然保持加载，不发送邮件
