ACF reCAPTCHA brings Google reCAPTCHA to <a href="https://wordpress.org/plugins/advanced-custom-fields/" rel="ugc">Advanced Custom Fields</a>, to be used on frontend forms.
Features include:
<ul>
<li>ACF reCAPTCHA Protection ensures that spambots cannot circumvent reCAPTCHA to submit forms on the server-side</li>
<li>ACF-compliant client-side validation which prompts the user if reCAPTCHA is not clicked or had expired</li>
<li>Customizable reCAPTCHA options, including theme (light/dark), type (image/audio) and size (normal/compact)</li>
<li>Compatible with ACF Conditional Logic feature, which allows hiding/showing certain fields until the reCAPTCHA has been passed</li>
</ul>

<h4>ACF Frontend Forms</h4>

Advanced Custom Fields: reCAPTCHA Field

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!

Works out of the box (when the keys are entered)

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.

Kinda works

Prevent spam on your Advanced Custom Fields (ACF) v5 frontend forms with Google reCAPTCHA.

Customize WordPress with Global Custom Fields! You can use GCF for example to create HTML + PHP shortcodes, global text fields, to save custom urls and retrieve them wherever you want and much more.
Add global fields in GCF Admin Page Create groups in the ‘Settings’ section and related fields in the ‘Fields’ section. Then edit the fields individually from the ‘GCF’ section.
Recover GCF with php Fields groups / single gcf can be retrieved anywhere within your theme / plugin with the function <code>get_gcf($group, $single = false, $eval = false)</code>
Show single GCF with a shortcode Load and display your single gcf with a shortcode! <code>[gcf group="group_name" field="field_name" eval=false]</code>
Each field is validated before saving. Add non-standard HTML tags and attributes in the “Settings” section if you need.
N.B. Use php “eval” only if you know what you’re doing. Save php fields using pseudo tags <code>[php] ... [/php]</code>
