我正在尝试在我的网站中实现录音机。我想要的是让用户将录制的文件直接保存到数据库和/或我网站上的子文件夹（称为/ speaking_audios）。主要文件如下：recorder.php，sync.html，upload.php，js / main.js，js / swfobject.js，js / recorder.js，recorder.swf（我不知道它的用途）
recorder.php

好吧，我只是想让你专注于upload.php文件，看看我做错了什么。
答案 0 :(得分：1)
处理文件时，需要有效的enctype和POST方法。
因此，您需要更改此表单：
<form id="uploadForm" name="uploadForm" action="upload.php">
对此：
<form enctype="multipart/form-data" method="post" id="uploadForm" name="uploadForm" action="upload.php">
并检查错误并确保您上传的文件夹具有正确的权限。
