电子邮件表单文件上传返回文件为空

Question

这是一个包含附件的简单 php 电子邮件表单。该表单可以正常工作，除了当文件为他们上传的附件上传但没有内容时。我相信这意味着为附件上传的文件没有被正确解码。代码如下：

    <?php 
$action = $_REQUEST['action']; 
if ($action=="")    /* display the contact form */ 
{
?>
    <form action="" enctype="multipart/form-data" method="post">

任何帮助将不胜感激。我可能完全错了为什么正在上传的文件被上传为空白但编码是一个暗示。

我尝试删除以下行：

    $content= chunk_split(base64_encode($content));

无济于事。有人知道吗？

玩了几个小时后，我终于弄明白了。我添加了一个调试功能，最初使用了 tmp_name。虽然我看不出我到底做了什么改变使它现在可以工作，但这是改变它的工作代码。
