Instead of installing a dozen separate single-purpose plugins, Kramar provides a focused set of tools in one clean package — 27 modules across ten areas. Every module is opt-in and disabled by default, so you only run what you actually use. **About the name:** _Kramar_ (крамар) is an old Ukrainian word for a _merchant_ — the town shopkeeper who dealt in wares. Its root, _kram_ (goods), is a medieval German trade-loanword that travelled east into the Slavic languages, a small echo of Europe’s old merchant network. Kramar is the toolkit that equips the merchant. #### What’s included * **EU & NL compliance** — Legal consent checkboxes, EU payment-obligation order- button text (Dutch Hoge Raad ruling), Omnibus 30-day lowest-price display, unit- price / delivery-time / tax notices, and a 14-day right-of-withdrawal / return flow. * **PDF documents** — Article 226-compliant invoices, packing slips, and credit notes, with sequential numbering and encrypted storage. * **Email** — A drag-and-drop email template builder, custom transactional emails with status / time-delay / manual triggers, and a developer API. * **Checkout** — A checkout field editor (classic + block checkout), address validation, EU VAT ID format validation for B2B orders, and a delivery-date picker. * **Order management** — Custom order statuses, sequential order numbers, and a refund / return workflow. * **Products** — Variation swatches (colour or image), minimum / maximum / step quantity rules, extra product option fields, and enhanced reviews (verified-buyer badge, helpful voting, rating breakdown). * **Marketing** — Google Shopping product feed, back-in-stock notifications, abandoned- cart recovery, and post-purchase review reminders — all consent-first. * **Customer account** — An enhanced My Account dashboard with order tracking, one-click reorder, and a smoother registration flow. * **Shipping** — Weight-based shipping rates. * **Performance** — Disable cart-fragment polling, dequeue unused WooCommerce CSS/ JS, and strip WooCommerce admin bloat. * **Privacy** — Order and review IP anonymisation, data-retention warnings, and scheduled PII cleanup. #### Built for the EU Kramar was designed from the ground up for EU and Dutch law. The compliance modules consider the GDPR, the Consumer Rights Directive, the Omnibus Directive, and Dutch civil-code requirements. They are entirely optional — the invoicing, email, product, performance, and order tools work for any store, anywhere. #### Modular Enable only what you need. Disabled modules have zero overhead — no hooks, no queries, no assets loaded. ### For Developers Kramar’s Email Manager module exposes a small PHP API for sending and scheduling custom emails from themes or other plugins. No code is needed to _create_ a custom email — use Kramar Emails Add New Email in the admin to build and configure it. Once it exists you can trigger it programmatically. #### Finding a custom email’s id Every custom email created through the UI gets an id of the form `kramar_custom_{ slug}`, where the slug is derived from the email name: spaces become underscores, all characters are lowercased, and the result is passed through `sanitize_key()`. Example: an email named “Review Request” becomes `kramar_custom_review_request`. The exact id is shown in the Custom Emails table on Kramar Emails. #### Sending immediately ``` kramar_send_email( string $id, mixed $context = null ): bool ``` Sends the custom email right now. Returns `true` if the email was dispatched (the email was found, is enabled, and passed the send filters). `$context` may be a ` WC_Order` object, an order id (integer or numeric string), or `null`. ``` kramar_send_email( 'kramar_custom_review_request', $order_id ); ``` #### Scheduling for later ``` kramar_schedule_email( string $id, mixed $context, int $timestamp ): bool ``` Schedules the email via Action Scheduler at the given Unix timestamp. Returns `true` if the action was queued (or was already queued). Requires WooCommerce’s bundled Action Scheduler. ``` kramar_schedule_email( 'kramar_custom_review_request', $order_id, time() + 7 * DAY_IN_SECONDS ); ``` #### Idiomatic do_action aliases Both functions are also wired to `do_action` so callers that prefer hooks over direct function calls can use: ``` do_action( 'kramar_send_email', $id, $context ); do_action( 'kramar_schedule_email', $id, $context, $timestamp ); ``` #### Filters **`kramar_email_recipient`** — Override the To address before the email is sent. ``` apply_filters( 'kramar_email_recipient', string $recipient, string $id, WC_Order|null $order ) ``` **`kramar_email_should_send`** — Return `false` to prevent a send entirely. ``` apply_filters( 'kramar_email_should_send', bool $should, string $id, WC_Order|null $order ) ``` **`kramar_email_merge_field_values`** — Add or replace merge-field values used inside email content. ``` apply_filters( 'kramar_email_merge_field_values', array $replacements, WC_Order $order ) ``` #### Worked example: review request 7 days after order completion ``` add_action( 'woocommerce_order_status_completed', function ( $order_id ) { kramar_schedule_email( 'kramar_custom_review_request', $order_id, time() + 7 * DAY_IN_SECONDS ); } ); ``` **Note:** The WooCommerce mailer caches its email list per request. A custom email created in the same PHP request as your `kramar_send_email()` call will not yet be registered and the call will return `false`. In normal use — emails created in the admin, triggered later by frontend or cron events — this is never a concern. #### Delivery time (template tag) Display a product’s delivery-time estimate anywhere in your theme: ``` kramar_get_delivery_time( int $product_id = 0 ): string ``` Returns the product’s own delivery-time term, falling back to the shop-wide default set in the EU Product Compliance module (or an empty string when neither is set). Works even when the automatic front-end display is turned off. Pass `0` to use the current global `$product`. ``` echo esc_html( kramar_get_delivery_time( $product->get_id() ) ); ``` **`kramar_delivery_time_label`** — Filter the resolved label. ``` apply_filters( 'kramar_delivery_time_label', string $label, int $product_id ) ``` **`kramar_delivery_time_html`** — Filter the rendered `` markup (escape your own output). ``` apply_filters( 'kramar_delivery_time_html', string $html, string $label, WC_Product $product ) ``` ## Screenshots [⌊Dashboard — get-started checklist, module/compliance stat cards, and an action- required panel.⌉⌊Dashboard — get-started checklist, module/compliance stat cards, and an action-required panel.⌉[ Dashboard — get-started checklist, module/compliance stat cards, and an action-required panel.

Open the **Kramar** menu in your admin sidebar and enable the modules you want. ## FAQ ### Does Kramar require WooCommerce? Yes. WooCommerce must be installed and active — Kramar declares it as a required plugin and will not run without it. ### Do I have to use every module? No. Every module is opt-in and disabled by default. A disabled module registers no hooks, runs no queries, and loads no assets. ### Are the PDF invoices legally compliant? Invoices include the fields required by Article 226 of the EU VAT Directive and use gap-free sequential numbering. Please confirm the output meets your obligations with your own accountant, as requirements vary by country and business type. ### Where are generated PDFs stored? They are stored encrypted inside your site’s uploads directory and are served only through authenticated, capability-checked download endpoints — never from a public URL. ### Can I use Kramar outside the EU? Yes. The compliance modules are optional. The invoicing, email, product, performance, and order-management tools work for any WooCommerce store. ### Can I send a custom email from my own code? Yes. Create the email in **Kramar Emails Add New Email**, then trigger it programmatically with `kramar_send_email()` or `kramar_schedule_email()`.
