Validation of Captcha in not working

Please follow https://www.shamimsplugins.com/docs/advanced-nocaptcha-recaptcha/getting-started-advanced-nocaptcha-recaptcha/implement-in-custom-form/

anr_verify_captcha() will return true only if validation success, in all other cache it will return false.

no result
I do this in my code
look:

if ( anr_verify_captcha() ) {
$request = $_POST;
$data_register = array(
‘user_login’ => trim( $request[‘user_login’]),
‘first_name’ => trim( $request[‘first_name’] ),

etc …
and in end

else{
wp_send_json(‘The captcha is wrong’);
}

if I select captcha, I see “The captcha is wrong”
if I not select captcha I see too “The captcha is wrong”

nothing result so far
i see the fuction anr_verify_captcha() is return nothing
no true no false

but when I setup your captcha to /wp-admin login form it is working fine

user: admin
pass: admin

how a can got capthca value ?

I see you are collecting individual field value of form in your js and submit via ajax.
You can instead use serialize (https://api.jquery.com/serialize/) to get all values of your form (including captcha) and send using ajax.
Or collect captcha value also and send with your other data. captcha field name g-recaptcha-response
