Why am I getting that error on Google reCAPTCHA V2 response?

Hello, it's my first time posting here and I'm not good with such stuff as the one I'm posting right now

I have been trying to solve this issue for 2 days by now so I could use some help lol

This error "Please solve the captcha." is showing even if the captcha is verified so it's showing in the both cases (verified/unverified).

Thanks in advance.

function submit(){
    global $API;

    if(empty($captcha) || $captcha == '' || !isset($captcha))

Variables defined outside functions are not available inside functions. They should be passed in as function arguments, like you're doing with post_content() and $query.

Are you not getting syntax errors with this? From my formatting of the code, you've got mismatched braces all over the place. It's hard to tell because you're bouncing between using braces and not (please stop doing that), but it looks like there are some nesting issues going on unless I'm mistaken. 

<?php
$response = array("error" => false , "success" => false , 'redirect' => false);

function post_content($query){
  $query_array = array();
  foreach( $query as $key => $key_value )
    $query_array[] = urlencode( $key ) . '=' . urlencode( $key_value );
  
  return implode( '&', $query_array );
}

global $API;
$opts = array('http' =>  array('method'  => 'POST',"header" => "Content-type: application/x-www-form-urlencoded\r\nAuthorization:".base64_encode($API["api_key"].":".$API["secret_key"])."\r\n", "content" => post_content($content)));

return stream_context_create($opts);  // WHAT ARE YOU RETURNING FROM?

}   //WHERE DOES THIS START?

function submit(){
  global $API;

  if(empty($captcha) || $captcha == '' || !isset($captcha))
    return array(    "error" => "Please solve the captcha.");

  if (empty($_POST['account']) || !ctype_alnum($_POST['account']))
    return array(    "error" => "Invalid account id.");
      
  $checkAccount = checkAccount($_POST['account']);

  if (isset($checkAccount["error"]))
    return array("error" => $checkAccount["error"]);

  if (isset($checkAccount["success"])){
    $account_unique_id = (isset($_SESSION['kal_id'])) ? $_SESSION['kal_id'] : $checkAccount["success"]; 
    $result = json_decode(file_get_contents($API["API_Domain"] . '/api/generate/vote-rewards-token', false, postParams(array('callback' => $API["callback"],'account_unique_id' => $account_unique_id    ))) , true);

  { // WHAT IS THIS FOR?

    echo '<br><center><h3>Please wait...</h3></center>';
  }
  if (!empty($result)){
    if (isset($result["response"])){
      if (isset($result["response"]["error"]))
        return array("error" => $result["response"]["error"]);

      elseif (isset($result["response"]["success"]))
        return array("redirect" => '<script type="text/javascript">setTimeout(function () { window.location.href = "'.$result["response"]["success"].'";}, 500)</script>');

    }
  }
  } //  WHAT?
}

if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['account'])){
  $response = submit();
  if (isset($response['redirect']) && $response['redirect']){
    echo $response['redirect'];
    die;
  }

  $result = json_decode(file_get_contents($API["API_Domain"] . '/api/verify/vote-rewards-token', false, postParams(array('returned_code' => $_GET['return']))) , true);
  if (!empty($result)){
    if (isset($result["response"])){
      if (isset($result["response"]["error"]))
        $response['error'] = $result["response"]["error"];

      elseif (isset($result["response"]["success"])){
        insertRewards($result["response"]["account_unique_id"]);
        $response['success'] = '<b>Thank you, Your vote has been recorded and the server rank will be updated soon.<b><br />You will receive your rewards in storage of your account.<p>Your next vote in : <b>' . $result["response"]["NextVote"] . '</b></p>';

I didn't code it to be honest, it was released online (without google recaptcha)
And no I'm not actually getting any syntax errors
Here is the original code where I got it : https://top-kal.com/api-docs/Kal-Online 
Thanks for answering though (:
