Mathematical Captcha Applier

Deskripsyon

Mathematical Captcha Applier is a lightweight WordPress plugin that lets you easily apply a simple math-based captcha to form submit buttons on your website by specifying their CSS selector. Just provide a specific button’s CSS selector, and the plugin will display a captcha prompt before the action is completed. This could help to prevent spam and unwanted bot activity.

Features:
– Add a mathematical captcha to form submit buttons (<input type="submit"> or <button type="submit">) by specifying their CSS selector (ID or class).
– Attempts to protect forms from automated submissions.
– No external dependencies — lightweight and fast.
– Simple configuration via the WordPress dashboard.
– If JavaScript is disabled, this plugin will hide the selected buttons.

How It Works:
When a user clicks the protected button, a small popup will appear asking them to solve a basic math problem (e.g., 5 + 3 = ?). If answered correctly, the action will proceed.

If JavaScript is disabled in the browser, the plugin hides the selected submit button.

Pag-install

  1. Upload the plugin files to the /wp-content/plugins/mathematical-captcha-applier directory, or install the plugin through the WordPress Plugins screen.
  2. Activate the plugin through the Plugins screen in WordPress.
  3. Go to Settings > Mathematical Captcha Applier to configure the buttons you want to protect.

FAQ

Does it require JavaScript?

Yes, the captcha popup and validation rely on JavaScript.

Is this plugin designed to handle all kinds of spamming threats?
