## Description
**CartTrigger – BAG** (Brand · Awards · Gallery) extends the WooCommerce native
brand taxonomy with three powerful modules:
#### Custom Fields
Attach unlimited key–value pairs to any brand. Output them anywhere via shortcode
or PHP helper function. CSS classes are fully customisable, including Tailwind arbitrary-
value classes (e.g. `text-[11px]`).
#### Awards
Manage a list of awards and recognitions for each brand — with optional logo, award
name, event name, and year. Display them as a styled list using the `[ctbag_awards]`
shortcode.
#### Gallery
Upload a curated image gallery per brand. Display it as a responsive grid with the`[
ctbag_gallery]` shortcode. Optional native WooCommerce lightbox (PhotoSwipe) via`
lightbox="1"`.
#### Shortcodes
**`[ctbag_custom_fields]`**
Outputs brand custom fields as a `` list.
```
[ctbag_custom_fields brand="slug" wrapper_class="..." dt_class="..." dd_class="..."]
```
**`[ctbag_awards]`**
Outputs brand awards as a styled card list.
```
[ctbag_awards brand="slug" title="Awards" wrapper_class="..." card_class="..."]
```
**`[ctbag_gallery]`**
Outputs brand gallery as a responsive image grid.
```
[ctbag_gallery brand="slug" title="Gallery" wrapper_class="..." lightbox="1"]
```
#### PHP Helper Functions
All shortcodes are also available as direct PHP functions that bypass WordPress’
shortcode parser — useful when Tailwind arbitrary-value classes (e.g. `text-[11px]`)
would otherwise be mangled:
```
echo ctbag_custom_fields(['wrapper_class' => 'grid grid-cols-2 gap-4']);
echo ctbag_awards(['title' => __('Awards', 'your-textdomain')]);
echo ctbag_gallery(['title' => __('Gallery', 'your-textdomain'), 'lightbox' => '1']);
```
#### Professional Admin UI
All brand meta fields are presented in a clean, card-based admin interface grouped
by module (HTML Description, Custom Fields, Awards, Gallery), with collapsible shortcode
reference built in. Custom fields and awards support drag & drop reordering. Gallery
images can be removed individually (× button on hover) and reordered by dragging.

## Installation
1. Upload the `carttrigger-bag` folder to the `/wp-content/plugins/` directory.
2. Activate the plugin through the **Plugins** menu in WordPress.
3. Go to **Products Brands** and edit any brand to start adding content.
## FAQ
### Does this plugin require WooCommerce?
Yes. WooCommerce must be active before activating CartTrigger – BAG. The plugin
declares a `Requires Plugins: woocommerce` dependency.
### Does it require a specific WooCommerce version?
WooCommerce 8.0 or higher is recommended. The plugin has been tested up to WooCommerce
10.6.1.
### Can I use Tailwind CSS classes in the shortcode attributes?
Yes, but classes containing square brackets (e.g. `text-[11px]`) will be interpreted
as shortcode closing tags by WordPress. Use the PHP helper functions instead — they
bypass the shortcode parser entirely.
### Where is the gallery lightbox loaded?
The lightbox uses WooCommerce’s bundled PhotoSwipe library. It is only active when`
lightbox="1"` is set. On pages where WooCommerce scripts are disabled, a graceful
fallback (open image in new tab) is used automatically.
### Gallery images look blurry or load slowly — what image size should I use?
The `size_thumb` parameter controls which registered WordPress image size is used
for gallery thumbnails. The default is `medium_large` (typically 768 px wide), which
is appropriate for large single-column layouts. If your gallery is displayed in
a multi-column grid (3–4 columns), use `size_thumb="medium"` (300 px) to reduce
file weight by 4–6× with no visible quality loss:
```
[ctbag_gallery size_thumb="medium" lightbox="1"]
```
Or via PHP helper:
```
echo ctbag_gallery(['size_thumb' => 'medium', 'lightbox' => '1']);
```
### Brand pages load slowly — any caching recommendations?
Brand taxonomy pages contain no user-specific content (no cart, no session), so
they are ideal candidates for full-page caching. Make sure your caching plugin (
LiteSpeed Cache, WP Rocket, W3 Total Cache…) does **not** exclude brand taxonomy
pages from its cache.
Since version 2.0.8, PhotoSwipe (4 CSS/JS files) is only enqueued on brand pages
that actually have a gallery, so brands without a gallery already load significantly
fewer assets.
If you use LiteSpeed Cache and notice that brand pages are slow after a product
update, check whether “Smart Purge on Product Update” is purging brand taxonomy
pages. Enabling the LiteSpeed Crawler ensures the cache is regenerated automatically
in the background so visitors never hit an uncached page.

## Changelog
#### 2.0.9
* Fix: corrected Contributors username in readme.txt to match the WordPress.org
plugin owner account.
#### 2.0.8
* Perf: PhotoSwipe CSS and JS are now enqueued only on brand pages that have a
gallery, instead of on every brand page. Brands without a gallery no longer load
4 unnecessary assets (2 CSS + 2 JS).
#### 2.0.7
* Fix: gallery images not saved after selection in the media uploader. Root cause:
HTML input had `id="ctb_gallery"` while the admin JS targeted `#ctbag_gallery`,
so the hidden field was never updated before form submission.
#### 2.0.6
* Fix: fatal error on brand save due to mismatched method name after 2.0.5 prefix
rename (`ctbag_save_term_meta`).
* Fix: added one-time migration to move existing term meta from legacy `ctb_*`
keys to `ctbag_*` keys.
#### 2.0.5
* Compliance: renamed all shortcodes and PHP helper functions from `ctb_*` to `
ctbag_*` to meet the WordPress.org 5-character prefix requirement (`ctbag` =
CartTrigger BAG).
* Compliance: extracted inline gallery lightbox JavaScript to an external file (`
assets/js/ctbag-gallery-lightbox.js`) loaded via `wp_enqueue_script()`.
* Compatibility: WC tested up to 10.6.1.
#### 2.0.4
* New: Gallery — individual image removal with an × button that appears on hover,
without reopening the media uploader.
* New: Gallery — drag & drop reordering of thumbnails (jQuery UI Sortable).
* New: Custom Fields — drag & drop reordering of field rows via a handle icon.
* New: Awards — drag & drop reordering of award rows via a handle icon.
#### 2.0.3
* Fix: double-quote characters (`"`) in award names, event names, and custom field
values were corrupted on save. Root cause: WordPress calls `wp_unslash()` (stripslashes)
on meta values inside `add_metadata()`, which stripped the backslash from `\"`
in the JSON string, producing invalid JSON. Fix: awards and custom fields are
now stored as native PHP arrays via `maybe_serialize()` — no backslash escaping
involved, immune to the slashing issue. Backward-compatible: existing JSON-format
data is still read correctly.
* Fix: accented characters (é, à, ó…) in award/field text were silently dropped
on some server configurations. Replaced `sanitize_text_field()` with `wp_strip_all_tags()`
to avoid the internal `wp_check_invalid_utf8()` call that incorrectly rejected
valid multi-byte characters.
#### 2.0.0
* Complete rewrite with professional admin UI (module cards).
* Added HTML Description module with TinyMCE editor on both Add and Edit brand
screens.
* Added native WooCommerce lightbox (PhotoSwipe) support for gallery shortcode.
* Added activation notice with link to brand management screen.
* Plugin fully internationalised — translations available for Italian (it_IT) and
Spanish (es_ES).
