Makuruwan Arithmetic Human Quiz

Description

Makuruwan Arithmetic Human Quiz adds a lightweight arithmetic human-verification challenge to WordPress login, standard WordPress comments, WooCommerce product reviews, and custom forms. It helps keep bots out without relying on Google reCAPTCHA or external services.

Comment and product-review protection is enforced server-side on the normal WordPress comment submission endpoint, so simply removing the visible quiz field does not bypass the check.

Screenshots

Installation

  1. Upload the plugin to /wp-content/plugins/makuruwan-arithmetic-human-quiz/ and activate it.
  2. Go to Settings Human Quiz to configure the quiz.
  3. Enable or disable protection separately for login, blog/post comments, and WooCommerce product reviews.
  4. To protect custom forms, add the shortcode [makarhq_human_check] inside your <form> markup.

FAQ

Can I protect only the login form?

Yes. You can enable or disable login protection in the plugin settings.

What shortcode should I use in custom forms?

Use [makarhq_human_check] inside your <form> tag so the fields are submitted with the form.

Does it protect WordPress comments?

Yes. Version 1.1.0 can require the arithmetic challenge before a visitor submits a normal WordPress comment.

Does it protect WooCommerce product reviews?

Yes. Product review forms can be protected independently from normal blog/post comments.

Are logged-in users also asked to solve the quiz on comments and reviews?

Yes. When comment or product-review protection is enabled, the challenge is rendered for both logged-in and logged-out users using the standard WordPress comment form hooks.
