WooCommerce Product Documents Enhancer

A lightweight WordPress plugin that injects dynamic product document sections into WooCommerce product pages using hooks, ACF, and taxonomy-aware logic. Designed to replace theme snippets with a maintainable plugin architecture.

Version: 1.1.0
License: GPL-2.0+
Platform: WordPress / WooCommerce
Dependencies: WooCommerce, Advanced Custom Fields (ACF)

Overview

This plugin adds a custom Downloads tab to WooCommerce product pages, displaying:

  • Product certification documents
  • Light photometric files (IES / LDT)

The solution is implemented as a standalone plugin to ensure stability across theme updates and to avoid fragile theme-based PHP snippets.

Key Features

  • WooCommerce-native product tab integration
  • Automatic certificate discovery via product taxonomy mapping
  • Photometric file support using ACF Post Object relationships
  • Shared photometrics across multiple products
  • External PDF redirect handling
  • Theme-agnostic architecture (tested with Porto)

Architecture Highlights

  • No shortcodes
  • No page builder dependency
  • Pure WooCommerce hooks
  • Safe execution order
  • Update-resistant plugin design

The project evolved from theme snippets into a structured plugin after theme updates removed custom PHP logic, a real-world refactor scenario.
