# Multi File Upload & Edit

changelogs available here:
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 & Featuraes
- **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 and upload speed (B/s, KB/s, or MB/s).
- For image files, a 32×32 pixel thumbnail preview is shown; for other files, a default file icon is displayed.

- **File Editing & Renaming:**
- Text-based files can be edited directly in a modal window.
- Files open in a modal that can be resized for ease of editing.
- **Rename functionality:** Every file now has a “Rename” button in the Actions column (in addition to the “Edit” button for editable files) so that any file can be renamed without editing.


- **Batch Deleting, Copying & Moving:**
- Users can select multiple files and perform batch actions like delete, copy, or move.
- The action buttons remain visible (if files exist) and only become active when one or more files are selected.
- The folder dropdown for copy/move actions is hidden when no files are present.
- **Sorting & Pagination:**
- Files can be sorted by attributes such as name, date modified, upload date, size, or uploader.
- A custom date parser converts dates from the "MM/DD/YY hh:mma" format (e.g. "03/07/25 01:01AM") to timestamps for reliable sorting.
- Pagination is implemented so users can view 10, 20, 50, or 100 items per page with navigation controls ("Prev"/"Next" and page numbers).
- **User Management & Authentication:**
- Secure, session-based authentication is implemented.
- Admin-only controls allow for adding and removing users.
- Passwords are hashed using PHP’s `password_hash()` function.


- **Dynamic & Responsive UI:**
- Real-time UI updates (via Fetch API and XMLHttpRequest) refresh the file list, upload progress, and folder list without a full page reload.
- On smaller screens, less critical columns (Date Modified, Upload Date, File Size, Uploader) are hidden for a cleaner mobile experience.
- A centered header with a logo and navigation buttons provides an intuitive interface.
- **Progress Feedback:**
- During file uploads, a progress list displays the status for each file (for the first 10 files) along with an indication if additional files are being uploaded.
- The file list refreshes immediately after uploads finish, while the progress list remains visible for a set period for user confirmation.
---
## Security
- **Password Hashing:**
- Uses PHP’s `password_hash()` and `password_verify()` functions to securely store and check user credentials.
- **Session-based Authentication:**
- User state is managed via PHP sessions.
- **Safe File Operations:**
- Uploaded file metadata (uploader, upload timestamp) is stored securely in a JSON file.
- **No-caching:**
- Appropriate headers are set (or timestamps appended) to ensure that file and folder lists are always up-to-date.
---
## User Experience & Interface
- **Responsive Design:**
- The interface adapts to different screen sizes using media queries.
- Critical information (filename and actions) remains visible on small screens, while secondary columns are hidden.
- **Modern Look:**
- A dynamic UI with asynchronous updates ensures real-time progress display and a modern user experience.
- **Intuitive Navigation:**
- A structured header with a centered title and clearly laid out action buttons makes navigation easy.
---
## Extensibility & Maintainability
- **Modular Code Structure:**
- The code is organized into separate ES6 modules:
- `networkUtils.js` – HTTP request handling.
- `domUtils.js` – DOM manipulation and UI update functions.
- `fileManager.js` – File operations, rendering, sorting, pagination, editing, and renaming.
- `folderManager.js` – Folder operations (loading, renaming, deleting).
- `upload.js` – File upload handling and progress display.
- `auth.js` – User authentication and management.
- **Improved Sorting:**
- A custom date parser converts date strings to timestamps for reliable sorting of date columns.
- **UI Updates:**
- Real-time updates and event reattachment ensure the file list and action buttons are always current.
- **Responsive & Accessible:**
- Media queries and dynamic button states improve usability across devices.
- **Clean & Extendable:**
- Legacy files have been removed and the code is structured for easy future enhancements.
---
## Deployment & Real-world Use
- **Reverse Proxy Compatibility:**
- Can be deployed behind a reverse proxy with proper configuration.
- **Practical Applications:**
- Ideal for document management, image galleries, firmware updates, and more.
- **Security & Scalability:**
- Session-based authentication, secure file operations, and modular code design ensure the application is secure and scalable.

## changes 3/8/2025
- Validation was added in endpoints.
- Toast notifications were implemented in domUtils.js and integrated throughout the app.
- Modals replaced inline prompts and confirms for rename, create, delete, copy, and move actions.
- Folder tree UI was added and improved to be interactive plus reflect the current state after actions.
## changes 3/7/2025
- **Module Refactoring:**
- Split the original `utils.js` into multiple ES6 modules for network requests, DOM utilities, file management, folder management, uploads, and authentication.
- Converted all code to ES6 modules with `import`/`export` syntax and exposed necessary functions globally.
- **File List Rendering & Pagination:**
- Implemented pagination in `fileManager.js` to allow displaying 10, 20, 50, or 100 items per page.
- Added global functions (`changePage` and `changeItemsPerPage`) for pagination control.
- Added a pagination control section below the file list table.
- **Date Sorting Enhancements:**
- Created a custom date parser (`parseCustomDate`) to convert date strings.
- Adjusted the parser to handle two-digit years by adding 2000.
- Integrated the parser into the sorting function to reliably sort “Date Modified” and “Upload Date” columns.
- **File Upload Improvements:**
- Enabled multi-file uploads with individual progress tracking (visible for the first 10 files).
- Ensured that the file list refreshes immediately after uploads complete.
- Kept the upload progress list visible for a configurable delay to allow users to verify upload success.
- Reattached event listeners after the file list is re-rendered.
- **File Action Buttons:**
- Unified button state management so that Delete, Copy, and Move buttons remain visible as long as files exist, and are only enabled when files are selected.
- Modified the logic in `updateFileActionButtons` and removed conflicting code from `initFileActions`.
- Ensured that the folder dropdown for copy/move is hidden when no files exist.
- **Rename Functionality:**
- Added a “Rename” button to the Actions column for every file.
- Implemented a `renameFile` function that prompts for a new name, calls a backend script (`renameFile.php`) to perform the rename, updates metadata, and refreshes the file list.
- **Responsive & UI Tweaks:**
- Applied CSS media queries to hide secondary columns on small screens.
- Adjusted file preview and icon styling for better alignment.
- Centered the header and optimized the layout for a clean, modern appearance.
*This changelog and feature summary reflect the improvements made during the refactor from a monolithic utils file to modular ES6 components, along with enhancements in UI responsiveness, sorting, file uploads, and file management operations.*
