Step 5: Editing your form and your view

For Google ReCaptcha V2 (invisible)

To enable Recaptcha (invisible) protection on your form, you must use this type: MaelRecaptchaSubmitType::class

// For example
->add('captcha', MaelRecaptchaSubmitType::class, [
    'label' => 'Submit',
    'constraints' => new MaelRecaptcha()
])

For the third parameter which is an array, you can add the constraint : MaelRecaptcha

Then, to complete the configuration of the invisible Recaptcha, in your twig file you need to add a id to your form

{{ form_start(your_form, {'attr': {'id': 'form-recaptcha'}}) }}

To finish, add 2 <script> tags

Replace "id-of-your-form" by the class of your form add just above it

<script src="https://www.google.com/recaptcha/api.js" async defer></script>
<script>
   function onSubmitCaptcha(token) {
       document.getElementById("class-of-your-form").submit();
   }
</script>

Warning, you cannot change the name of the JavaScript function.
