表单中的WP邮件附件，没有在Filemanager上上传文件

Question

我试图通过wp_mail函数从表单发送带有附件的电子邮件，而不将文件上传到文件管理器。我收到带有附件的电子邮件。但是附件名称不正确，没有文件类型。请帮助解决此问题。

这是HTML表格

<form action="POST" enctype="multipart/form-data">
    <table>
        <input type="file" name="Attached">
        <input type="Submit" name="Submit">
    </table>
</form>

有我的PHP代码

if (isset($_POST['Submit'])) {
    $attachments = $_FILES['Attached']['tmp_name'];

    $recipients = "john@mail.com";
    $SenderName = get_bloginfo('name');
    $SenderEmail = "noreply@domain.com";
    $body   = "How are you what are you doing now. bla bla bla";

    $recipients = array($to);
    $headers[] = "From: $SenderName <$SenderEmail>" . "\r\n";
    $headers[] = "Content-Type: text/html";
    $subj = "This is mail subject";
    $SendMail   = wp_mail( $recipients, $subj, $body, $headers, $attachments );
}
