with reCAPTCHA

====== Google ReCaptcha ====== Google reCAPTCHA is a convenient alternative to traditional CAPTCHA for verifying visitors. Here's how to set it up: 1. Visit https://developers.google.com/recaptcha and register to obtain: - reCAPTCHA V3 Site Key - reCAPTCHA V3 Secret Key 2. Enter these values in Rotation > Settings > Social, and enable "Use Captcha on Comments?" ===== reCAPTCHA for comments ===== reCAPTCHA works by adding Google's JavaScript code to your form to verify the user is not a bot, storing the verification result in a hidden field. Here's an example for a comments page. Add this code to the HTML head section:



  
     <!--GALLERY_SLUG--> with reCAPTCHA

Note that is your reCAPTCHA V3 Site Key (not the secret key). Here's the comment form itself:




' != 'OK') echo "error: "; ?>



 Google will write the answer here

Name: 



 

 Note: this is a button, not a submit button. The form only submits after Google approves the user.

===== reCAPTCHA Anticheat ===== reCAPTCHA can also be used to monitor traffic quality. Google analyzes traffic and reports the percentage it considers legitimate (non-bot). Add the following code to your site (typically on index and category pages):

Add class='gallery_link' to links to galleries or categories as in the example below

You can replace gallery_link with any class name. The key is to attach a bot detection event to your links using JavaScript: $('.gallery_link').each(function() { ... }). 4. In the admin panel, go to Settings > Layouts and enable the Google reCAPTCHA column. Now you can view the percentage of legitimate traffic in Trade > reCAPTCHA column. **Note:** Google allows only 1300 free checks per hour, so not all hits are analyzed—they're sampled based on RECAPTCHA_MAX_RATE. If you need unlimited checks, contact support about paid options.
