Blast Vintners Wine List

A WordPress plugin holding the bespoke wine-list storefront for blastvintners.com.

Nothing here is new behaviour. This is the same code that has been running the wine list for years — it just used to live in the wrong place.

Why this plugin exists

The wine list is not a TablePress setting and it is not custom CSS. It is custom PHP that had been edited directly into five files belonging to other people's software:

Two consequences followed from that:

1. TablePress could never be updated. An update overwrites its own files, so the wine list would vanish. The plugin has been frozen at version 1.4 (2014) ever since — while the database still records tablepress_version: 1.9.2, which is the fingerprint of an update that was applied and then rolled back.
2. The theme could never be updated or changed, because one of the five files was the theme's own functions.php.

With the code here instead, TablePress can be updated and the theme can be changed or replaced without the wine list noticing.

How it hooks in

Documented TablePress and WordPress hooks only. No third-party file is modified.

• tablepress_table_output — adds the Buy column, the expandable descriptions and the "Show Descriptions" toggle to any table that has a stored row → product map
• wp_head — prints the tbpwooaddToCart() script and the .tbp-woo-* styles
• wp_ajax_my_custom_add_to_cart / wp_ajax_nopriv_my_custom_add_to_cart — the add-to-basket endpoint (same action name as before, so nothing else has to change)
• admin_footer — puts the "Add Woocommerce Product" tickbox back on the TablePress import screen
• save_post_tablepress_table — when that box is ticked, creates the products and stores the row → product map in the _table_press_woo_products post meta
• also carried over from the theme: the ?ifr iframe/Safari-cookie block, and the filter that hides thumbnails in the cart

Verified equivalence

The refactor was checked against the unmodified site rather than assumed:

• the rendered wine list was captured before and after and compared node by node — 46,690 elements, attributes, values and text, in order
• the only differences on the wire are whitespace, attribute quote characters, and < inside one tasting note now being correctly escaped to <. A real browser reports that description as an identical 417-character string either way
• add-to-basket was driven end to end in a real browser: 772 Buy buttons, quantity options 1–13 matching the 13 bottles in stock, and the basket showing £31.00, matching that row's "Inc Duty & Vat" column
• every file lints clean under PHP 8.3, which is the version this site is moving to

Known quirks, reproduced deliberately

These are faithful to the original so that the page renders identically. They are not endorsements — see NOTES.md.

• the Buy column's <th>/<td> carry class="column-5", which duplicates the Unit column's class. Some of the site's CSS depends on it
• the scroll-and-notice JavaScript is hard-coded to #tablepress-39-scroll-wrapper, so on any table other than 39 the confirmation message has nowhere to go
• the stored meta key is prodcut_id, spelled that way in the original
