內容簡介
揭密：
LIBRARY VIEWER FILE MANAGER ADD-ON已經發佈了！來看看吧 😉
使用 Library Viewer，你可以顯示你的 (FTP) 伺服器某個「特定資料夾」的包含檔案和資料夾給前端使用者查看。
與其他類似的插件相比，最大的不同是：
1. 你可以允許使用者查看檔案是否存在，但如果使用者未登錄 (或者不是管理員、作者等)，就無法打開檔案。
2. 你可以允許使用者在自定義檢視器中查看檔案，或將其重新導向到你選擇的 RESTful 網路服務（下面有範例）。
範例
對於此插件（免費版本），「特定資料夾」是你的 httpdocs(yoursite.com/library) 中的「library」資料夾。
如果你想顯示不在 yoursit.com/library 中的其他資料夾（及其檔案），你需要使用Library Viewer Pro的路徑參數。
這個插件在 WordPress 網站中添加了 [library-viewer] 短碼！
所以，你只需要在帖子、頁面、小工具等中添加這個短碼，就可以在前端顯示資料夾和檔案。
[library-viewer] 短碼還有可選參數，可以擴展插件的功能：

原文外掛簡介
New in Version 3.3.0: Admin Library Viewer!
You can now manage and browse your library directly from your WordPress dashboard. Go to Media > Library Viewer to get started.
Library Viewer allows you to display files and folders from your server directly on your WordPress site.
By default, the free version displays the contents of the “library” folder located in your site’s root directory (example: yoursite.com/library). To display any other directory, you can use the path parameter available in Library Viewer Pro.
Whether you want to create a public document library, a members-only download area, or an internal file portal, Library Viewer provides a lightweight and flexible solution.
Unlike traditional file manager plugins, Library Viewer focuses on controlled visibility and flexible file access.
You can:
Allow users to browse files without allowing them to open or download them
Restrict file access based on login status or user roles
Open files using custom viewers or external services
Integrate file access with WooCommerce purchases
Manage your library directly from the WordPress dashboard

Custom Viewer: Open files in a custom viewer or redirect them via a web service of your choice.
Breadcrumb Navigation: Easy navigation through subfolders.
Search & Filter: Show or hide specific files and folders (Pro version).
Quick Start
Create a folder named “library” in your server root (e.g. public_html/library)
Upload your files and folders inside it
Add the shortcode [library-viewer] to any page or post
Publish the page and view your library
(Optional) Use shortcode parameters to control access and behavior
To view your library in the backend, navigate to Media > Library Viewer.
Library Viewer Admin Pages
ADMIN PAGE DOCUMENTATION
The Library Viewer Admin Pages feature, introduced in version 3.3.0, brings library functionality directly into your WordPress dashboard.
It is designed for site owners and administrators who need quick access to their libraries without visiting the front end.
Unlike a single fixed admin screen, Library Viewer allows you to register multiple Library Viewer Admin Pages, each with its own configuration, permissions, and displayed library.
For advanced usage and full configuration options, please refer to the Admin Page Documentation.
Key Features of the Admin Page:
Centralized Browsing: View all files and folders in your “library” folder (or in other directories when using Library Viewer Pro) directly from the Media > Library Viewer menu.
Customizable Access: You can define exactly which user roles or capabilities (e.g., editors, custom roles) have permission to view this admin page.
Flexible Display: The admin page uses the same powerful engine as the shortcode. In the “Library to display” field, you can set any [library-viewer] shortcode with the parameters of your choice (as described in the Parameters Documentation) to customize the backend display.
Easy Navigation: Includes a dedicated “Settings” tab where you can change the page title and manage access permissions without touching any code.
How to Use:
Go to your WordPress Dashboard.
Navigate to Media > Library Viewer.
Use the Library tab to browse your files.
Switch to the Settings tab to customize the title or restrict access to specific roles.
