# WooCommerce Bootstrap

A WordPress child theme of [WP Bootstrap](https://src.bundespruefstelle.ch/magdev/wp-bootstrap) that overrides all [WooCommerce](https://github.com/woocommerce/woocommerce.git) plugin templates with Bootstrap 5 structures and styling.

## Requirements

- WordPress 6.7+
- PHP 8.3+
- [WP Bootstrap](https://src.bundespruefstelle.ch/magdev/wp-bootstrap) theme (parent)
- [WooCommerce](https://github.com/woocommerce/woocommerce.git) plugin
- Composer

## Installation

1. Install and activate the parent theme `wp-bootstrap`
2. Install and activate the `woocommerce` plugin
3. Upload `wc-bootstrap` to `wp-content/themes/`
4. Run `composer install` in the theme directory
5. Activate the theme in WordPress Admin > Appearance > Themes

## How It Works

WooCommerce renders its pages using PHP templates loaded via `wc_get_template()`. This child theme intercepts that process with a **Twig rendering bridge** that replaces the PHP output with Bootstrap 5 styled Twig templates.

The bridge hooks into WooCommerce's `woocommerce_before_template_part` and `woocommerce_after_template_part` actions. When a matching `.html.twig` template exists, it is rendered via the parent theme's TwigService and the original PHP output is discarded. If no Twig override exists, the default PHP template renders normally.

### Key Features

- **99 Twig template overrides** covering all customer-facing WooCommerce pages
- **Rendering bridge** (`WooCommerceExtension` + `TemplateOverride`) that intercepts WooCommerce's PHP template pipeline
- **~50 Twig functions** and **7 Twig filters** exposing WooCommerce and WordPress APIs to templates
- Bootstrap 5 responsive markup with dark mode support
- HPOS compatible (uses `WC_Order` methods only, no `$post` global)
- 8 reusable Twig components (card, pagination, price, rating, address-card, status-badge, quantity-input, form-field)
- Translation-ready

### Architecture

```txt
WooCommerce wc_get_template("cart/cart.php")
  → woocommerce_before_template_part hook
    → TemplateOverride checks for cart/cart.html.twig
    → Found → renders via TwigService (with WooCommerceExtension functions)
    → Starts output buffer
  → PHP include (captured in buffer)
  → woocommerce_after_template_part hook
    → TemplateOverride discards buffered PHP output
  → Result: Bootstrap 5 Twig output only
```

### Building Translations

```bash
for po in languages/wc-bootstrap-*.po; do msgfmt -o "${po%.po}.mo" "$po"; done
```

## Releases

Releases are automated via Gitea Actions. Push a tag matching `vX.X.X` to trigger a release build.

```bash
git tag -a v0.1.0 -m "Version 0.1.0 - Initial release"
git push origin v0.1.0
```
