Kitgenix Document Manager

Description

Kitgenix Document Manager lets admins upload documents and share a stable link like:

/kitgenix-document-manager/{slug}/

When you replace the file, the link stays the same and serves the new version.

Key Features

• Stable links: replace the file without changing the URL
• Admin documents table with search, copy link, and “Open link” action
• Quick edit modal (popup) for editing documents without leaving the table
• Document Categories: create categories and assign documents for easier organization
• Visibility controls: Public or Private documents
• Private behavior: redirect to login or return 403
• Serving mode: Inline (browser) or Download (attachment)
• Optional version history per document, including restore/delete for older versions
• Bulk version cleanup: delete all old versions for a document (Versions tab + modal action)
• Select from Media Library: optionally pick an existing Media Library file instead of uploading
• Safer serving: correct Content-Type where possible, security headers, and conditional caching for public docs

Usage

1. Go to Kitgenix → Document Manager
2. Add a document (name + optional slug) and upload the initial file
3. Copy the stable URL from the table and share it
4. To update a document later, use Edit (modal) and upload a replacement file
5. If Keep version history is enabled for that document, older files will appear in the Versions panel (restore/delete)

Categories:

• Use the Categories tab to add/edit/delete categories
• Assign a category when adding/editing a document

Note: Inline viewing works best for PDFs and images. Office documents (DOCX/XLSX/etc.) typically download because browsers can’t render them natively.

Settings

Settings are available under the Settings tab:

• Allowed file extensions
• Default visibility (Public/Private)
• Serving mode:
  • Inline (browser)
  • Download (attachment)
• Versioning defaults (keep history by default, delete old versions when history is disabled)
• Private document behavior (login redirect or 403)
• Delete all plugin data on uninstall (optional)

Frontend card options are available under the Frontend tab:

• Default document card button label
• Button style (Outline or Solid)
• Preview image size
• File type/file size alignment
• Button alignment
• Button colors (normal + hover)
• Option to open the “View” button in a new tab
• Toggle showing file type and file size
• Toggle showing document description
• Shortcode Builder (generate a shortcode for one or multiple documents)

Security & Caching

• Private documents are not cached (no-store) and require login (or return 403)
• Public documents use conditional caching (ETag/Last-Modified) so browsers/CDNs can revalidate efficiently (including 304 Not Modified responses)
• Responses include security hardening headers like X-Content-Type-Options: nosniff
• Private documents include X-Robots-Tag: noindex, nofollow

External Services

This plugin includes a shared “Kitgenix hub” component in wp-admin which may fetch publicly available plugin metadata from WordPress.org using the WordPress core plugins_api() function (WordPress.org Plugins API).

• When it runs: only in wp-admin (Kitgenix plugin admin pages)
• Data sent: plugin slug(s) (no personal data)
• Data received: publicly available plugin information (e.g. active installs, ratings)
• Caching: responses are cached locally using transients for ~1 day:
  • kitgenix_hub_wporg_active_installs_v1
  • kitgenix_hub_wporg_ratings_v1
