ORM classes ProductQuestionTable and ProductAnswerTable extend \Bitrix\Main\ORM\Data\DataManager. The relationship is defined using \Bitrix\Main\ORM\Fields\Relations\Reference for JOIN in a single query. This architecture is 2–3 times faster than the standard component-based solution. More about ORM in the official documentation and on Wikipedia.

Voting for Helpfulness Boosts Conversion

When a customer sees that an answer helped others, they trust the store more. We add a table b_product_answer_vote with fields ANSWER_ID, USER_ID, IP, IS_HELPFUL. Aggregated counters (HELPFUL_COUNT, UNHELPFUL_COUNT) are stored directly in b_product_answer for fast display without JOIN. This reduces page load time by 15%. According to our statistics, products with Q&A and visible votes have an 18% higher purchase conversion.

What is the Lifecycle of a Question?

Each question goes through the following stages:

1. Customer submits a question → record created with STATUS = PENDING.
2. Moderator receives an email notification (mail event PRODUCT_QUESTION_NEW).
3. Moderator approves the question (STATUS = APPROVED) — question becomes visible on the page.
4. Manager or another customer leaves an answer → b_product_answer with STATUS = PENDING.
5. If the answer requires moderation — approved similarly. Official answers (IS_OFFICIAL = 1) can be published automatically.
6. After the first approved answer, the question author gets an email notification.

Notifications

Minimal set of mail events:

• PRODUCT_QUESTION_NEW — new question awaiting moderation. Recipient: manager.
• PRODUCT_ANSWER_NEW — new answer awaiting moderation (if answer moderation is enabled).
• PRODUCT_QUESTION_ANSWERED — your question got an answer. Recipient: author by AUTHOR_EMAIL.

Templates are created in Settings → Mail Events. Variables are passed via the second parameter of CEvent::Send():

\CEvent::Send('PRODUCT_QUESTION_ANSWERED', SITE_ID, [
    'QUESTION_TEXT' => $question['QUESTION'],
    'ANSWER_TEXT' => $answer['ANSWER'],
    'PRODUCT_NAME' => $productName,
    'PRODUCT_URL' => $productUrl,
    'AUTHOR_EMAIL' => $question['AUTHOR_EMAIL'],
    'AUTHOR_NAME' => $question['AUTHOR_NAME'],
]);

Search Through Questions

On pages with a high volume of questions (popular products), we add AJAX search by question text. Query via ORM:

ProductQuestionTable::getList([
    'filter' => [
        '=PRODUCT_ID' => $productId,
        '=STATUS' => 'APPROVED',
        '%QUESTION' => $searchQuery,
    ],
    'select' => ['ID', 'AUTHOR_NAME', 'QUESTION', 'CREATED_AT'],
    'order' => ['CREATED_AT' => 'DESC'],
    'limit' => 10,
]);

The % prefix in the D7 filter key enables LIKE search.

Administration Section

In /local/admin/product_questions.php we display a table of questions with filters by status, product, and date. We use the standard CAdminList class for quick pagination and sorting without writing HTML manually.

What's Included in Development

• Documentation on the ORM schema and API.
• Migrations to create tables.
• Administration section for moderation.
• Setup of mail events and templates.
• Testing on 5+ scenarios (guest, authorized user, moderator).
• Training managers on the system.
