我在网站上上传图片时遇到了一些麻烦。我有一个上传页面，可让人们将条目上传到手册中。但是当我上传图片时，$ _FILES数组是空的。我有：
enctype="multipart/form-data" 777 POST 我已在我的服务器here上传了phpinfo（）的输出。
无论我在哪里，都没有任何帮助。请注意，我在本地计算机上运行此程序，Mac（10.11.4）与Apache 2.4.18和PHP 5.5.31。
我使用Why would $_FILES be empty when uploading files to PHP?的答案来检查这些事情。
以下是代码：
上传页面（upload.php）：
<?php include "sql.inc"; ?>

<head>

padding: 5px;
}
</style>
</head>
<body>
<h1>Upload an entry to the Handbook!</h1>
<center>
<form action="upload_page.php" method="POST" enctype="multipart/form-data">
