Changes 3/3/2025: folder management added some refactoring # Multi File Upload & Edit This project is a lightweight, secure web application for uploading, editing, and managing files. It’s built with Apache, PHP, and modern front-end JavaScript, and it features a responsive interface with dynamic updates. --- ## Functionality & Features - **Multi-file Upload:** Users can select and upload multiple files at once. Each file’s upload is tracked individually with a progress bar showing percentage complete and upload speed (B/s, KB/s, or MB/s). If an image is selected, a small 32×32 pixel thumbnail preview is displayed; otherwise, a default file icon is shown. - **File Editing:** Built-in editing functionality for text-based files allows quick modifications directly within the browser. Files open in a modal window with a consistent, rounded design. Edit window can be resized to allow for easier editting. - **Batch Deleting:** Users can select multiple files and delete them in one action, streamlining file management. - **Sorting & Filtering:** Files can be sorted by attributes such as name, date modified, upload date, size, or uploader, making it easier to navigate large file sets. - **User Management:** Secure, session-based authentication is implemented along with admin-only controls for adding and removing users. Passwords are hashed for security. - **Dynamic UI Updates:** The application uses asynchronous JavaScript (via the Fetch API and XMLHttpRequest) to update the file list and upload progress in real time without requiring full page reloads. - **Progress Feedback:** During uploads, each file shows a progress bar next to its name, complete with upload percentage and speed. Once all files have been uploaded, the progress list automatically clears after a short delay. --- ## Security - **Password Hashing:** PHP's `password_hash()` and `password_verify()` functions are used to securely store and check user credentials. - **Session-based Authentication:** User state is managed using PHP sessions, with proper access control for admin-specific actions. - **Safe File Operations:** Uploaded file metadata (including uploader and upload timestamp) is stored in a JSON file, minimizing exposure of sensitive data. --- ## User Experience & Interface - **Responsive Design:** The interface adapts seamlessly to different screen sizes, ensuring usability on desktops, tablets, and mobile devices. - **Modern and Dynamic:** The application uses dynamic UI updates (via the Fetch API and XMLHttpRequest) to show real-time progress for each file upload, including visual feedback with thumbnail previews and progress bars. - **Clean and Intuitive Layout:** A structured header with a logo, centered title, and action buttons (Logout, Add User, Remove User) provides an intuitive navigation experience. --- ## Extensibility & Maintainability - **Modular Code Structure:** The codebase is organized into separate files (e.g., `auth.js`, `upload.js`, `displayFileList.js`), making it easy to manage and extend. - **Removal of Legacy Files:** Files such as `checkUploadLimit.js`, `checkUploadLimit.php`, and `getUploadSize.php` are no longer used and have been removed to streamline the project. - **Customization Options:** The project is flexible and can be adapted to support additional file types, enhanced previews, or integration with other systems. --- ## Deployment & Real-world Use - **Reverse Proxy Compatibility:** With proper configuration, the application can be deployed behind a reverse proxy, providing an additional layer of security. - **Practical Applications:** This multi-file uploader with editing and user management is ideal for scenarios involving document management, image galleries, firmware updates, and more. --- - **Login Page** fork of: https://github.com/sensboston/uploader # File Uploader A simple file uploader web app that allows authenticated users to upload, list, and delete files. The application uses PHP, running on Apache2, Ubuntu (but definitely should work everywhere). ## Prerequisites - Apache2, configured, up and running - PHP 8.1 or higher - Required PHP extensions: `php-json`, `php-curl` ...........
