Google recaptcha sends without confirmation, why?

Question

PHP

Please tell me there was a contact form with another captcha, it was cut out, everything works fine.
I connected the recaptcha from the client side, everything also works fine
. But now it doesn’t work with the server to get it working.

Recaptcha check handler based on the Spoiler tutorial

if($_SERVER['REQUEST_METHOD'] == 'POST'){


  if(empty($_POST['g-recaptcha-response'])){

    $recaptcha = $_POST['g-recaptcha-response'];

    $url = 'https://www.google.com/recaptcha/api/siteverify';
    $secret = 'туть секретный ключ';
    $ip = $_SERVER['REMOTE_ADDR'];
    $url_data = $url.'?secret='.$secret.'&response='.$recaptcha.'&remoteip='.$ip;

    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL,$url_data);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,FALSE);

    curl_setopt($curl, CURLOPT_RETURNTRANSFER,1);

    $res = curl_exec($curl);
    curl_close($curl)
    $res = json_decode($res);
    if($res-> sucsess){

    }else{
  }
}

Can't figure out what to do next or what am I doing wrong?
Sending a Server Internal Error

Answer 1

You have banal syntax errors in the code "Recaptcha check handler which is written according to the Spoiler lesson"
curl_close($curl) - there is no semicolon at the end.
if($_SERVER['REQUEST_METHOD'] == 'POST'){ - no closing bracket.
You need to use a normal IDE (PHPStorm) that will immediately underline your jambs in red, and you do not need to spend so much time on such banal errors. I just pasted your code into PHPStorm and it showed all the problem areas
and be sure to read PSR-1 PSR-2
