Advanced Custom Fields: reCAPTCHA Field

Description

ACF reCAPTCHA brings Google reCAPTCHA to Advanced Custom Fields, to be used on frontend forms.

Features include:

  • 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 Compatibility

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.

  2. Find the reCAPTCHA field type under Custom.
  3. Enter your site key and secret key that was generated previously.
  4. (optional) Configure the theme, size and type of the reCAPTCHA widget.

Plugin works great. I had a few questions and ideas, and the dev was amazingly quick to respond, eager to help, and very collaborative. 5 stars!

Tried using this with an acf_form that created a new post, using the method to put it inside the acf_form() function. It worked, but you have to submit the form once before you can fill out the rest of the form. This actually creates blank posts! And configuration is just very convoluted. Some other reviews say it worked out of the box. What? Not for me. But I’m not using it in a field group, because it should only appear for guests. Oh well.

Had some issues in the past, but have edited this review as this plugin has been updated and works perfectly now.

Although it seems this plugin was broken and not maintained for several months, I’ve installed it just now, exactly one week since it’s last update – and it’s simple functionality just – works. I hope it will continue to work and that Google won’t change much in their API, but in case something does break, I will return here to add comments to this review. Till then, I believe the author deserves 5 stars for his effort, at least to improve the overall rating of the plugin which is currently (unjustified) 3.3 Keep up the good work!
