Question

I want to have a recaptcha system to my contact form symfony. For that I use a EWZRecaptchaBundle. But I try lot of stuff tricks for running recaptcha but my form submit run without testing validation recaptcha widget (invisible and visible)
Can you help me to run recaptcha correctly. My submit form run without deal with recaptcha but I have the widget display correctly.

private_key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
locale_key: %kernel.default_locale%
locale_from_request: false
enabled: true
verify_host: true
ajax: false
ContactType
->add('recaptcha', EWZRecaptchaType::class, array(
'attr' => array(
'options' => array(
'theme' => 'light',
'type' => 'image',
'size' => 'invisible',
'defer' => true,
'async' => true,
'callback' => 'onReCaptchaSuccess',
'bind' => 'contact_submit',
)
),
'mapped' => false,
'constraints' => array(
new RecaptchaTrue()
)
)
)
// ->add('recaptcha', EWZRecaptchaType::class)
->add('submit', SubmitType::class, [
'label' => 'form.submit.send',
'attr' => ['class' => 'btn1 form_recaptcha_submit', 'id' => 'contact_submit']
])
Twig template
{{ form_widget(form.recaptcha, { 'attr': {
'options' : {
'theme': 'light',
'type': 'image',

private $recaptcha;
I have the widget recaptcha google which display correctly but my submit form don't work with this. never.
I have registered my domain on google website recaptcha

You need to define the validation in your form (it is also possible to validate in the entity class). Also in my case I did not create a field in my eneity. I prefered to use what we call a "non mapped" field. To use a non mapped field you just need to use 'mapped' => false, in your contactType
I show you below the code I used:
My ContactType:
->add('recaptcha', EWZRecaptchaType::class, array(
'attr' => array(
'options' => array(
'theme' => 'light',
'type' => 'image',
'size' => 'normal',
'defer' => true,
'async' => true,
)
)
,
'mapped' => false,
'constraints' => array(
new RecaptchaTrue()
)
))
I give you my config.yml so you can see I don't need that much options to be defined to make recaptcha works:
ewz_recaptcha:
public_key: xxxx
private_key: xxxx
# Not needed as "%kernel.default_locale%" is the default value for the locale key
locale_key: %kernel.default_locale%
locale_from_request: true
edit: to display the recaptcha widget with twig in my template, I just use {{ form_end(form) }} and the recaptcha widget is on top of the submit button.
edit 2: You don't need to do any validation in your controller but this one:
if ($contactForm->isSubmitted() && $contactForm->isValid())
{
//your logic
}
