Informations about the package silverstripe-nocaptcha

Nocaptcha

Adds a "spam protection" field to SilverStripe userforms using Google's reCAPTCHA service.

Requirements

Installation

After installing the module via composer or manual install you must set the spam protector to NocaptchaProtector, this needs to be set in your site's config file normally this is mysite/_config/config.yml.

Finally, add the "spam protection" field to your form by calling enableSpamProtection() on the form object.

Configuration

There are multiple configuration options for the field, you must set the site_key and the secret_key which you can get from the reCAPTCHA page. These configuration options must be added to your site's yaml config typically this is app/_config/config.yml.

Adding field labels

If you want to add a field label or help text to the Captcha field you can do so like this:

Commenting Module

When your using the silverstripe/comments module you must add the following (per their documentation) to your _config.php in order to use nocaptcha/spamprotection on comment forms.

Retrieving the Verify Response

If you wish to manually retrieve the Site Verify response in you form action use the getVerifyResponse() method

ReCAPTCHA v3

ReCAPTCHA v3 is different to v2, users won't be presented with a "Are you a robot?" checkbox, instead user actions are returned a spam score 0.0 to 1.0 when they submit the form. Out of the box, this module will block any submission with a spam score of <= 0.4 but this can be tailored either site-wide using the Config API

Or on a per form basis:

For more information about version 3, including how to implement custom actions see https://developers.google.com/recaptcha/docs/v3

Handling form submission

By default, the javascript included with this module will add a submit event handler to your form.

If you need to handle form submissions in a special way (for example to support front-end validation), you can choose to handle form submit events yourself.

This can be configured site-wide using the Config API

Or on a per form basis:

With this configuration no event handlers will be added by this module to your form. Instead, a function will be provided called nocaptcha_handleCaptcha which you can call from your code when you're ready to submit your form. It has the following signature:

form must be the form element, and callback should be a function that finally submits the form, though it is optional.

In the simplest case, you can use it like this:
