ACF reCAPTCHA brings Google reCAPTCHA to Advanced Custom Fields, to be used on frontend forms.
- ACF reCAPTCHA Protection ensures that spambots cannot circumvent reCAPTCHA to submit forms on the server-side
- ACF-compliant client-side validation which prompts the user if reCAPTCHA is not clicked or had expired
- Customizable reCAPTCHA options, including theme (light/dark), type (image/audio) and size (normal/compact)
- Compatible with ACF Conditional Logic feature, which allows hiding/showing certain fields until the reCAPTCHA has been passed
For more detailed setup instructions, or to report an issue, please head over to the GitHub repository here.
ACF Frontend Forms
ACF reCAPTCHA is meant to be used only on frontend forms, in order to protect them from spam by spambots.
To create a frontend form programmatically, please view the official documentation on the ACF website here.
ACF reCAPTCHA is currently only compatible with ACF v5 at the moment. If you would like to help to add support for v4, do submit a PR on GitHub.
In order to use ACF reCAPTCHA, you need to generate your reCAPTCHA API keys for your domain at the Google reCAPTCHA Dashboard first.
- In the ACF field group edit page, click Add Field to add a new field.
- Find the reCAPTCHA field type under Custom.
- Enter your site key and secret key that was generated previously.
- (optional) Configure the theme, size and type of the reCAPTCHA widget.
- Important: Scroll down to the bottom of the page, and enable ACF reCAPTCHA Protection for the field group.
