Multi File Upload & Edit

changelogs available here: https://github.com/error311/multi-file-upload-editor-docker/

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.
