Creating a CAPTCHA in Drupal 8 is essential to protect your website from spam and automated bots. A CAPTCHA is a challenge-response test used to determine whether the user is human or a machine. In this guide, I'll provide you with step-by-step instructions to add a CAPTCHA to your Drupal 8 forms using the "reCAPTCHA" module, which is widely used and well-maintained.
Step 1: Install and Enable the reCAPTCHA Module- Log in to your Drupal 8 admin panel.
- Go to Extend (Modules) by navigating to "Extend" from the top admin menu.
- Search for "reCAPTCHA" in the module list or browse to find it.
- Click the checkbox next to "reCAPTCHA" to select it for installation.
- Click the "Install" button at the bottom of the page.
- After installation, click the "Enable" button to enable the module.
Step 2: Obtain reCAPTCHA API keys- Visit the Google reCAPTCHA website: https://www.google.com/recaptcha
- Click the "My reCAPTCHA" button at the top-right corner and log in with your Google account.
- Register your website by filling in the necessary details (e.g., Label, reCAPTCHA type, Domains, etc.).
- Agree to the reCAPTCHA terms of service and click "Submit."
- After registration, you will receive two keys: Site key and Secret key. Keep these keys handy, as you'll need them in the next step.
Step 3: Configure reCAPTCHA settings in Drupal- In your Drupal admin panel, navigate to Configuration > People > CAPTCHA (admin/config/people/captcha).
- Under the "CAPTCHA module" drop-down, select "reCAPTCHA" as the CAPTCHA module to use.
- Scroll down to the "reCAPTCHA settings" section and enter the obtained Site key and Secret key in their respective fields.
- Select the reCAPTCHA version (v2 or v3) you want to use.
- Configure other settings like CAPTCHA position, theme, and error message behavior as per your preferences.
- Click the "Save configuration" button at the bottom to save the settings.
Step 4: Add CAPTCHA to your Drupal forms- Go to the form settings page where you want to add the CAPTCHA (e.g., Contact form, User registration form, Comment form, etc.).
- Click on the "Form display" or "Manage form display" tab, depending on your Drupal version.
- Locate the field that represents the form element where you want the CAPTCHA to appear (e.g., "CAPTCHA" for the contact form).
- Drag and drop the "CAPTCHA" field into the form layout, positioning it where you want the CAPTCHA to appear.
- Save the form display settings.
Step 5: Test the CAPTCHA- Visit the form on the frontend of your Drupal website where you added the CAPTCHA (e.g., Contact page, Registration page).
- Fill out the form and submit it to see the CAPTCHA in action.
- If the CAPTCHA is configured correctly, you should see the reCAPTCHA challenge, and after solving it, your form submission should go through.
Congratulations! You have successfully added a CAPTCHA to your Drupal 8 forms using the reCAPTCHA module, helping protect your website from spam and unwanted bot activities.
