README

A spam protector and form field using the Google's reCAPTCHA 3 that supports multiple forms

Based on https://github.com/UndefinedOffset/silverstripe-nocaptcha - The main changes are the way it injects CustomJs, most of it has been moved to the JS file.

Requirements

• SilverStripe 4.x
• SilverStripe Spam Protection 3.x
• PHP CURL

Installation

composer require swordfox/silverstripe-recaptchamultiple

After installing the module via composer or manual install you must set the spam protector to RecaptchaMultipleProtector, this needs to be set a config file e.g. mysite/_config/recaptchamultiple.yml.

SilverStripe\SpamProtection\Extension\FormSpamProtectionExtension:
  default_spam_protector: Swordfox\RecaptchaMultiple\Forms\RecaptchaMultipleProtector

Add the "spam protection" field to your form fields.

$form->enableSpamProtection()
	->fields()->fieldByName('Captcha')
	->setTitle("Spam protection")
	->setDescription("Please tick the box to prove you're a human and help us stop spam.");

Set a callback for each field, handy for ajax forms

$form->enableSpamProtection()
	->fields()->fieldByName('Captcha')
	->setCallback("onSubmit");
