我正在使用名为“Postlet”的java HTTP上传小程序。我设置PHP脚本来存储文件并将文件名存储在数据库中。当我使用一个简单的HTML测试表格上传一张图片时，它工作正常，但即使我只选择一个文件，它在我使用实际的applet时也不起作用。
java applet就好像一切都成功报告图像上传成功但文件无处可寻。我甚至使用了一个带有简化PHP文件的新applet，applet再次表示一切都很成功。但它没有在数据库中输入任何内容，也没有上传文件。
我的脚本在这里减去了安全措施的一些MySQL内容和文件目录：P
<?php
session_start();
$albumID = $_SESSION['albumID'];
$author = 1;
/*
The following file enables the uploading of each image from the java applet.
PLEASE NOTE, THIS FILES IN ITS PRESENT FORM IS A MASSIVE SECURITY RISK, AND
SHOULD NOT BE USED WITHOUT DOING EITHER OF THE FOLLOWING:

PROTECT IT BY USING HTTP PASSWORDS)

TO A DIRECTORY ABOVE THE DOCUMENT ROOT)

知道为什么它可能不起作用吗？
