shopextensions

German-market extensions for silvershop/core. The base module covers a shop, but not everything the German market needs — this package fills those gaps without forking silvershop, so projects ported from SilverStripe 4/5 to 6 keep working.

Setup- & Konfigurationsanleitung: siehe docs/USAGE.md (Installation, Pflicht-Setup, alle Config-YAML-Variablen, SiteConfig-Felder).

What it does

Invoices & PDFs — OrderExtension adds invoice/billing meta fields, assigns sequential invoice numbers from a configurable number range, and renders invoice + delivery-slip PDFs via dompdf (Receipt.ss / DeliverySlip.ss). The PDFs are streamed by the access-controlled OrderReceiptController (route OrderReceipt/StreamReceipt/<ID>, plus a PreviewReceipt/<ID> action that rasterises the first page to a PNG via ImageMagick for the CMS preview; download and preview restricted to the owning member or a CMS user) and, for customers, by AccountPageControllerExtension. Zero-value (0 €) orders get no invoice unless Order.issue_invoice_for_zero_total is enabled. Also provides getDescription(), which is required by payment gateways such as Mollie/PayPal.

Checkout usability — CheckoutPageControllerExtension + Checkout\ShopCheckoutComponentConfig swap in a cleaner checkout form (CompositeFields flattened, shipping address hidden when nothing ships, zero-total redirect fixed). Projects that need extra checkout fields subclass ShopCheckoutComponentConfig, override addProjectComponents() (runs between Notes and Terms) and point CheckoutPageControllerExtension.checkout_component_config_class at their own class — project-specific components never live in this module. AddressExtension localises country names and adds Company/Name fields. AjaxCartController / ShoppingCartControllerExtension / ProductControllerExtension power the AJAX mini-cart and live variant prices.

Payment robustness — ExtendedPurchaseService injects the order description, terms-page service URL and language into the gateway request and removes reserved params (a common Mollie failure).

Tax & shipping — CustomTaxModifier supports inclusive/exclusive tax and per-product or static rates; ProductExtension adds the per-product tax field. CustomShippingModifier is a deprecated legacy calculator (session billing country, flat domestic rate, weight tiers abroad; rates configurable) that is not registered by default; new shops should use their own modifier.

Notifications — CustomOrderEmailNotifier (Injector override) sends order emails through the SendOrderEmailJob queued job and attaches the invoice PDF; attachment is configurable per mail type.

Configuration — SiteConfigExtension moves operator-facing settings (receipt logo, header, footer, phone, admin notification recipient, invoice number prefix/start, checkout hints) into the CMS SiteConfig. The enabled_fields config array selects which fields are shown per project; see _config/siteconfig.yml.example.

Optional add-ons (shipped but off by default, opt-in via YAML — see docs/USAGE.md §7–8):

• Accounting export — OrderTaxExtension (per-tax-rate breakdown with coupon/gift-card/ shipping distribution, B2C & B2B) + ReceiptExportController (DATEV-EXTF CSV + collected PDF), with a month/year trigger panel in the Shop SiteConfig tab. Enable via _config/receiptexport.yml.example.
• Checkout payment tiles — PaymentMethodComponent lets the customer pick the concrete payment method (e.g. a Mollie sub-method) as a JS-free radio tile; the choice is persisted on the order and forwarded to the provider (paymentMethod) to skip its selection screen. Enable via _config/paymenttiles.yml.example.

Debug

Overwrite Receipt.ss and DeliverySlip.ss in templates. On 404 after e.g. Mollie returns "paid" and the order is not found, check if emails can be sent without error.

Debug Hint: set Order to paid in Database and call /OrderReceipt/StreamDeliverySlip/$OrderID and /OrderReceipt/StreamReceipt/$OrderID to test for errors

You may also need to apply the silvershop.patch for Address Fields to correctly display in default templates just add/require "cweagans/composer-patches" -> composer update -> add
"patches": { "silvershop/core": { "Made Address Fields not in composite field": "silvershop.patch" } }, to your "extra" in composer.json and update again (first one needed for composer-patches to install second needed for the patch to be applied)
