在浏览器中管理文件和目录
Manage files and directories in browser
我正在使用名为 Couch (CouchCMS) 的基于 PHP 的 CMS。
界面非常简单。编辑页面内容很容易，基本上就是这样。
我现在正在尝试添加功能。我想添加一个名为 "files" 的选项卡。此选项卡激活后将显示我的所有文件。例如，它会显示我的 "images" 文件夹和位于我网站文件夹中的所有其他文件。
是否可以通过 PHP 以某种方式在我的网页上显示我的所有目录并从那里添加和删除它们？
尝试使用这个函数：http://php.net/manual/en/function.readdir.php
但我认为您可以使用 jQuery + PHP 库来为您执行此操作：
https://www.sitepoint.com/10-jquery-file-manager-plugins/
这是用于 Silverstripe cms 的 php 代码，不知道它是否适合您。

我正在使用名为 Couch (CouchCMS) 的基于 PHP 的 CMS。
界面非常简单。编辑页面内容很容易，基本上就是这样。
我现在正在尝试添加功能。我想添加一个名为 "files" 的选项卡。此选项卡激活后将显示我的所有文件。例如，它会显示我的 "images" 文件夹和位于我网站文件夹中的所有其他文件。
是否可以通过 PHP 以某种方式在我的网页上显示我的所有目录并从那里添加和删除它们？
尝试使用这个函数：http://php.net/manual/en/function.readdir.php
但我认为您可以使用 jQuery + PHP 库来为您执行此操作： https://www.sitepoint.com/10-jquery-file-manager-plugins/
