What this solution does
Mathematical Captcha for Standard Bitrix Forms
This module replaces the standard Bitrix graphical captcha with a simple arithmetic verification in feedback forms. Users solve a basic math problem (e.g., 3 + 7 = ?), which simplifies interaction and improves conversion rates.
Key features:
Integration via the CAPTCHA replacement mechanism;
Generation of examples with adjustable difficulty (addition, subtraction, multiplication);
Difficulty settings configured in the administrative panel.
Implementation details:
Utilizes native Bitrix functions without modifying the core;
Requires no external services or image generation;
Operates server-side without JavaScript dependency.
Compatibility:
Compatible with standard feedback forms (bitrix:main.feedback, bitrix:form);
Does not support AJAX mode;
Incompatible with Aspro templates and solutions.
Note: This module is not intended for AJAX forms, as the captcha state is not preserved between requests.
For “TVM.MathCaptcha”, General iT can perform integration, configuration and a final check after installation.
