Answer 1

You can also use JavaScript for google captcha validation before form submit . 您还可以在表单提交之前使用JavaScript进行Google验证码验证。

var v = grecaptcha.getResponse();
if(v.length == 0){
    document.getElementById('captcha').innerHTML="You can't leave Captcha Code empty";
    error = false;
}else{
    document.getElementById('captcha').innerHTML="";
}  
if(error !== false){
    $('#yourformid').submit();
}

return false;

Answer 2

I believe there is an issue with this line: 我相信这条线有问题：

if(isset($data->success) AND $data->success==true)

It should be: 它应该是：

if(isset($data->success) AND $data->success===true)

Other than that, I would suggest using the Google Composer library ( https://github.com/google/recaptcha ) to validate the recaptcha. 除此之外，我建议使用Google Composer库（ https://github.com/google/recaptcha ）来验证Recaptcha。 It will solve you lines of code and headaches since they will keep it up to date. 它将解决您的代码行和头疼问题，因为它们将使它们保持最新。
