Magento Module Code Security
In Magento 2 stores built on a multistore setup, the same scenario appears very often: one language version (for example, EN) already has hundreds of reviews and a real sales history, while newly launched versions (DE/FR/ES/IT/NL/SE/CZ…) look empty, even though you sell the same products. This reduces credibility and conversion in new store views.
Kowal_ReviewTranslation solves this in a Magento-native way:
It does not create copies of reviews and does not multiply review_id.
It preserves native rating calculations, review counts, averages, and filters — because Magento still sees the same review, only with a different text layer for the given Store View.
Translations are saved per Store View in a separate table, so you can manage content independently for each language version.
How it works in practice
In the admin panel, you open a review and switch the Store View (the standard Magento switcher).
For the selected Store View, you edit: nickname, summary (title), review (detail).
The module saves the translation to its own table and does not overwrite the original.
On the frontend, Magento automatically displays the translation in the appropriate store view.
The customer sees a Show original / Show translation button, which uses AJAX to replace the content without reloading the page.
Key benefits
Credibility for new language versions from day one (reviews are visible immediately).
No issues with rating aggregation or review counters (Magento handles this natively).
No duplication of reviews or ratings in the database — clean and safe.
Simple admin workflow (no separate translation screens).
Frontend-friendly UX (toggle the original with 1 click).
On shop.vitcas.com, the largest review base was created in the English store (EN). After launching additional language versions (DE, FR, ES, IT, NL, SE, CZ), the new store views had few reviews, which reduced product credibility in new markets.
Kowal Review Translation enabled:
translation of review content from EN into the other languages (per Store View),
keeping one review and one set of ratings in Magento (without copies),
immediate “completion” of new language versions with social proof,
adding a “Show original” button on the frontend so users can view the source version.
Result: new language versions launch with full product credibility, without waiting to collect reviews from scratch.
