Features

  • Extra fields “Questions and answers” on product displays and “Frequently asked questions” on the term displays of your product vocabularies, placed in Manage display
  • Commerce › Product questions with Questions, Privacy and Settings tabs, an entity autocomplete product filter and a Questions tab on every product
  • Replies sent through Drupal’s mail manager (hook_mail) in the language the question was asked in; a notice to the site email for new questions
  • Permission “Manage product questions” for the roles that answer; the public endpoint is a POST route excluded from the page cache
  • Cache tags on the blocks (own tag, settings, language) so the internal page cache and Dynamic Page Cache stay right after every answer
  • Anti-spam without captcha: signed token fetched by the browser, honeypot, rate limits per IP hash and email, banned words
  • Categories and brands taken from the products’ taxonomy reference fields; FAQPage JSON-LD on their term pages
  • Cron erases email addresses after the retention period; JSON export and deletion per email; .po files for Spanish and French

Drupal Commerce product pages show what you wrote; shoppers’ doubts go to the contact form, or nowhere. Product Questions & Answers adds a Questions and answers field to the product display: a list of answered questions, a search box, helpful votes and an Ask a question form that works for guests and logged-in users.

Questions arrive in the store admin. You answer, choose whether it is published — only possible when the visitor agreed — and Drupal mails the reply in the language of the page they asked from. Term pages of your product categories collect a FAQ of the shop’s own answers and the product answers you mark for them.

How it fits into Drupal Commerce

Store admin
Commerce › Product questions (list by status, editor, privacy tools) and Commerce › Configuration › Products › Product questions (settings), under the restricted Manage product questions permission. Products get a Questions local task.
Display
Two extra fields — on product types and on the vocabularies your products reference — placed by the installer and movable in Manage display. Built from the shared markup, rendered with Markup::create() and cached with the module’s tag, the settings and the interface language.
Mail
plugin.manager.mail and the module’s hook_mail, so whatever mail plugin your site uses applies.
Endpoint
A POST route (/product-questions/endpoint, with the language prefix) marked no_cache; the page itself holds no token and no user data.
Cron
Email addresses past the retention period, IP hashes and votes older than a day are erased.
Tested on Drupal 11.3 with Commerce 3, Olivero and Claro, in English, Spanish and French.

FAQ

Where do brands come from?

Commerce has no brand entity: a taxonomy field or vocabulary of your products named brand (marca, marque, manufacturer) is used as brands, the others as categories.

Does the page cache still work?

Yes. The block is the same for every visitor and carries cache tags; the token and the user’s details come from the uncached endpoint.

Is anything published without consent?

No. Without the visitor’s tick, the answer is mailed and never shown.

FAQ rich results?

Google shows them only for some government and health sites since 2023; the term page markup is valid structured data, nothing more is promised.

Abandoned Cart Recovery

Drupal Commerce module for draft orders that never reach checkout completion: it emails the customer up to three times from cron, with a signed link that refills the cart and an optional coupon from a Commerce promotion.

  • Works on Commerce draft orders (carts) and stops on the order place transition, for customers and guests who passed the contact step
  • Coupons belong to a Commerce Promotion named “Abandoned cart recovery: N%”, one per percentage, not combinable
  • Runs from Drupal cron, with a Send due reminders now button for the impatient

Back in Stock & Price Drop Alerts

Drupal Commerce has no stock tracking of its own, let alone a way for customers to wait for a sold-out variation. This module reads the stock field you choose and lets visitors ask for one email when a product is available again or cheaper.

  • A “Stock & price alerts” component for Manage display, enabled on the default display of every product type at install
  • Works with any number field on your variations (field_stock by default); without one, only price-drop alerts are offered
  • Checked whenever a product or variation is saved, and swept by Drupal cron for every active alert

Chat & Order for WhatsApp

Drupal Commerce module that turns WhatsApp into a sales channel: chat buttons with opening hours, product questions and shares, carts placed as orders in a new workflow state awaiting confirmation, and staff message templates on the admin order page.

  • Floating chat button printed through hook_page_bottom, with one to three contacts in a keyboard-friendly panel and a first message per installed language
  • Opening hours per weekday in the default store’s time zone, evaluated in the browser so the page cache stays valid; outside them the button says when you reply, or hides
  • “Ask on WhatsApp” and “Share on WhatsApp” as an extra field of every product type, placed in Manage display; the question carries the product title, SKU and address

Estimated Delivery Date & Time Slots

Drupal Commerce module that shows an estimated delivery date from your own dispatch calendar, adds a Delivery checkout pane where customers book a day and time slot with limited seats, and keeps the promise on the order for receipts, accounts and a daily delivery sheet.

  • Estimated delivery date as an extra field of every product type, placed in Manage display; the same cached HTML for all visitors, with the countdown and the date worked out in the browser in the default store’s time zone
  • Business-day calendar: cut-off time per weekday, preparation days for the store and per category or product picked by autocomplete, delivery weekdays and closed dates, with a range when the fastest and slowest delivery differ
  • National holidays of fifteen countries computed for every year, Easter-based days and substitute days included, preselected from the default store’s address and untickable one by one
