/* K1 per-shop custom JS — k-v-mechelen.myshopify.com (shop.kvmechelen.be) * * Bug: the Radikal personalization theme adds to cart via a BULK * POST /cart/add (fetch, JSON) { items:[{child +€15 print},{parent shirt}] } * building its own payload from the personalization inputs and DROPPING the K1 * pre-order markers (properties[_K1], properties[Pre-order]) that the widget * injected into the product form. The parent shirt line therefore reaches the * cart as a REGULAR line; the K1 Cart Validation Function (online-sellable = 0, * stock on a non-online location) rejects it with * 422 "Only 0 available for Thuisshirt 26/27 Volwassenen". * The bulk add is atomic -> nothing is added. * * Fix: intercept the bulk /cart/add and, for each item that is a K1 pre-order * variant, re-attach the SAME markers the widget puts on the on-page product * form (properties[_K1], properties[Pre-order], selling_plan when present), * preserving the personalization properties (name/number/_bundle*). The +€15 * "Bedrukking" child (not in any K1 rule) is left untouched. * * Faithful (mirrors the native form for the current product), async ruleId * resolution as a fallback for co-added K1 products, idempotent, fail-open. * Verified live on shop.kvmechelen.be 2026-08-02. */ (function () { 'use strict'; try { if (window.__k1PersoCartFixInstalled) return; window.__k1PersoCartFixInstalled = true; var RESOLVE_TIMEOUT_MS = 3000; function isCartAdd(url) { try { return String(url).split('?')[0].replace(/\.js$/, '').replace(/\/$/, '') === '/cart/add' || /\/cart\/add(\.js)?($|\?)/.test(String(url)); } catch (e) { return false; } } // Snapshot the markers the widget put on any on-page product form, keyed by // the form's variant id.

grids: no

, * no

, no `.grid`/`.grid__item`, no element. So preorder-catalog-v2's * resolveParent() selector chain matches NOTHING and every card is discarded before a badge is * rendered (measured on the live storefront: home 9/9 cards -> null, collection 20/20 -> null). * The PDP is unaffected — it resolves via `section.o-product.js-main-product`. * * WHAT THIS DOES — and deliberately does NOT do * It does NOT re-implement badge rendering. It only adds two marker classes that the widget's * EXISTING chains already recognise, so the widget keeps owning every piece of business logic * (rule matching, the rule's `display` mode, per-variant limits, badge text + localization, * the storefront heartbeat): * `wt-product` -> resolveParent() alternative #5 — ahead of li (#9), * section (#11) and .grid (#19), so it wins regardless of * what a given Radikal section wraps its cards in. * `product-card--image-wrapper` -> findImageContainer() generic alternative #3 — ahead of * `.swiper-wrapper` (#10), which inside a Radikal collection * card is the IN-CARD image slider: a badge appended there * would travel with the carousel slide. * `.m-product-card__media` is the correct anchor box: position:relative, overflow:hidden, one * per card. (`.m-product-card__image` is position:static — a badge there escapes its card.) * * SAFETY * - Neither marker class is used by this theme: grepped 94 KB of its stylesheets (base-style, * product-card-style, main-collection-grid-style, featured-collection-style, price-style, * product-quick-add-style, cart-drawer-item-style) -> 0 hits for both, with a positive control * of 29 hits for `m-product-card`. So they carry no styling of their own and cannot alter layout. * - Each marker is read in exactly ONE place in preorder-catalog-v2.js and nowhere in * payment-options-v2.js / cart-allocator-v2.js. * - The CART DRAWER is skipped on purpose: its card anchor already carries class `grid`, so it * resolves via `.grid` today and must stay byte-identical. * - Fail-open throughout: any throw leaves the page exactly as it is today. * * REMOVE THIS once the widget ships native Radikal support (.m-product-card in the parent chain * + a .m-product-card__media branch in findImageContainer). */ ;(function () { try { if (window.__k1RadikalCardFixInstalled) return window.__k1RadikalCardFixInstalled = true var CARD = '.m-product-card' var MEDIA = '.m-product-card__media' var PARENT_MARKER = 'wt-product' var MEDIA_MARKER = 'product-card--image-wrapper' function tagAll() { try { var cards = document.querySelectorAll(CARD) for (var i = 0; i < cards.length; i++) { var card = cards[i] try { var media = card.querySelector(MEDIA) if (!media) continue // Already fully tagged -> nothing to do (keeps the observer path cheap). if ( card.classList.contains(PARENT_MARKER) && media.classList.contains(MEDIA_MARKER) ) { continue } if (card.closest('.cart-drawer')) continue card.classList.add(PARENT_MARKER) media.classList.add(MEDIA_MARKER) } catch (e) {} } } catch (e) {} } // Custom JS is injected by injectDesignConfig() BEFORE the widget's first findProducts() // run, so this first pass covers the server-rendered cards. tagAll() // Radikal re-renders the grid on facet/sort/pagination changes and injects quick-view and // recommendation cards later, so re-tag on DOM changes; the widget's own body // MutationObserver then re-runs findProducts() over the newly tagged cards. // Observing childList only (NOT attributes), so our own classList writes cannot re-trigger it. var timer = null try { var mo = new MutationObserver(function () { if (timer) clearTimeout(timer) timer = setTimeout(tagAll, 200) }) mo.observe(document.documentElement, { childList: true, subtree: true }) } catch (e) {} } catch (e) {} })()
