I created this reCaptcha code, it works well but I don not know how can I validate it, I thought it was validating with the function
grecaptcha.getResponse(); but it was not so.
Apparently The recaptcha worked well on the website but I just saw in Google admin the next message:
Requirements:
1.Do not use action="file.php" in the form, only a javascript function in the form.
<!DOCTYPE>
<html>
<head >
<title></title>
<script src='.js'></script>
<script type="text/javascript">
function get_action() {
var v = grecaptcha.getResponse();
console.log("Resp" + v );
if (v == '') {
document.getElementById('captcha').innerHTML = "You can't leave Captcha Code empty";
return false;
}
else {
document.getElementById('captcha').innerHTML = "Captcha pleted";
return true;
}
}
</script>
</head>

How can I validate it since I need to use a javascript function onsubmit="return get_action();" instead of action="file.php" *when I submit?:

Reset to default 7The grecaptcha.getResponse() function will only provide you with the user response token, which then must be validated with HTTP POST call on google reCAPTCHA server.
You could use AJAX request, to validate the token, but these validations should always be done on server side, for security reasons - JavaScript could've always been meddled with by user and tricked into believing that reCAPTCHA was successfully verified.
Google reCAPTCHA docs:
After you get the response token, you need to verify it with reCAPTCHA using the following API to ensure the token is valid.
So what you need to do is to send your reCAPTCHA secret (second key that was generated for you in reCAPTCHA admin page) and user response token (the one received from grecaptcha.getResponse() function) to reCAPTCHA API as described in reCAPTCHA docs.
In PHP, you'd do somethink like this:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.google./recaptcha/api/siteverify");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query([
'secret' => YOUR_RECAPTCHA_SECRET,
'response' => USER_RESPONSE_TOKEN,
]));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
$response = @json_decode($data);
if ($response && $response->success)
{
// validation succeeded, user input is correct
}
else
{
// response is invalid for some reason
// you can find more in $data->{"error-codes"}
}
This is what I would suggest...
1.) Append a query string to your reCPATCHA script. Also for better performance, prevents render blocking, you can add async defer attributes to your <script ...>. And for correctness you should move the script to after the <form> in the DOM. ...</form> <script src='https://www.google./recaptcha/api.js?onload=recaptchaRender' async defer></script>.
2.) Add a new function called recaptchaRender(). To handle your validation to Google and offload the response to you callback get_action. Replace RECAPTCHA_SITE_KEY to with your Google site key.
function recaptchaRender{
grecaptcha.render( 'reCaptchSubmit', {
'sitekey': 'RECAPTCHA_SITE_KEY',
'callback': get_action
});
}
3.) Add id="reCaptchSubmit" to your submit button.
4.) Remove onsubmit="return get_action();" from your form element.
Essentially you were missing the authentication between your script and Google. This doesn't handle your forms validation, but will at least get you to your render callback get_action(), where you can handle validation - might want to rename to something more relevant i.e. validateForm() etc
