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.

I know this thread is over two weeks old, but here's my contact page PHP

Code: Select all

<?php

require_once '../private/initialize.php';

    $smarty->assign('display_status', false);

use Library\Email\Email;
$highlight = ["normal", "normal", "normal", "normal", "selected", "normal"];

$username = \NULL;
$success = "Contact Form";
$token = $_SESSION['token'];
$db = DB::getInstance();
$pdo = $db->getConnection();

if (!isset($_SESSION['user']->id)) {
    $smarty->assign('security_level', \NULL);
    $login_status = FALSE;
} else {
    $smarty->assign('security_level', $_SESSION['user']->security_level);
    $login_status = TRUE;
    $username = $_SESSION['user']->username;
}

$submit = filter_input(INPUT_POST, 'submit', FILTER_SANITIZE_FULL_SPECIAL_CHARS);
if (isset($submit) && $submit === 'submit') {
    $token = filter_input(INPUT_POST, 'token', FILTER_SANITIZE_FULL_SPECIAL_CHARS);
    if (!empty($token)) {
        if (hash_equals($_SESSION['token'], $token)) {
            /* The Following to get response back from Google recaptcah */
            $url = "https://www.google.com/recaptcha/api/siteverify";

            $remoteServer = filter_input(INPUT_SERVER, 'REMOTE_ADDR', FILTER_SANITIZE_URL);
            $response = file_get_contents($url . "?secret=" . PRIVATE_KEY . "&response=" . \htmlspecialchars($_POST['g-recaptcha-response']) . "&remoteip=" . $remoteServer);
            $recaptcha_data = json_decode($response);
            /* The actual check of the recaptcha */
            if (isset($recaptcha_data->success) && $recaptcha_data->success === TRUE) {
                $success = "Mail was sent!";
                $data['name'] = filter_input(INPUT_POST, 'name', FILTER_SANITIZE_FULL_SPECIAL_CHARS);

                $data['comments'] = filter_input(INPUT_POST, 'comments', FILTER_SANITIZE_FULL_SPECIAL_CHARS);

                $send = new Email($data);
            } else {
                $success = "You're not a human!"; // Not of a production server:
            }
        } else {
            // Log this as a warning and keep an eye on these attempts
        }
    }
}

$smarty->assign('holidayMessage', $holiday_message);
$smarty->assign('highlight', $highlight);
$smarty->assign('title', "Contact Page");
$smarty->assign('pagename', ucfirst($pageName));
$smarty->assign('username', $username);
$smarty->assign('login_status', $login_status); // Login Status:
$smarty->assign('token', $token);
$smarty->assign('success', $success);
//$smarty->caching = 1;


$smarty->assign('calendar', $calendar);
$smarty->display('contact_template.tpl');
I use a Smarty a template engine as I find it easier separating the PHP from the HTML/CSS. plus it adds a little more security to the php. Anyways look at the PHP code after the third nested if statement as that is the meat & potatoes of the reCAPTCHA portion of it.

Here's the HTML template

Code: Select all

    {$title|escape}
