Verification "g-recaptcha-response" PHP doesn't work

Hi there,I've tried some solutions, proposed in different blogs. None of them works, the form can still be sent without filling the reCaptcha-checkbox. The support of the earlier version 1.0 seemed to be more explained. OK, it's very easy to display the new one in a website, but what good is that if validation is so difficult. I'm not a programmer but a webdesigner.I would love it someone could help me with a hint about my error or something else that really works with my process_form.php. The lines in red I found on Youtube, don't wor, maybe the reson is, they are wrong implemented.field_rules = array(    'field1'=>'required',    'field2'=>'required',    'field6'=>'email|required',    'field7'=>'required');$form->validate();class ProcessForm{    public $field_rules;    public $error_messages;    public $fields;    private $error_list;    private $is_xhr;    function __construct()    {        $this->error_messages = array(            'required' => 'Bitte füllen Sie dieses Feld aus',            'email' => 'Bitte geben Sie eine gültige E-Mail-Adresse an',            'number' => 'Bitte geben Sie einen numerischen Wert ein',            'url' => 'Bitte geben Sie eine gültige URL ein',            'pattern' => 'Bitte korrigieren Sie diesen Wert',            'min' => 'Bitte geben Sie einen größeren Wert als das Minimum ein',            'max' => 'Bitte geben Sie einen kleineren Wert als das Maximum ein'        );                $this->field_rules = array();        $this->error_list = '';        $this->fields = $_POST;        $this->is_xhr = $this->xhr();    }    function validate()    {        if (!empty($this->fields))        {            //Validate each of the fields            foreach ($this->field_rules as $field => $rules)            {                $rules = explode('|', $rules);                foreach ($rules as $rule)                {                    $result = null;                    if (isset($this->fields[$field]))                    {                        $param = false;                        if (preg_match("/(.*?)\[(.*?)\]/", $rule, $match))                        {                            $rule = $match[1];                            $param = $match[2];                        }                        $this->fields[$field] = $this->clean($this->fields[$field]);                        //if the field is a checkbox group create string                        if (is_array($this->fields[$field]))                            $this->fields[$field] = implode(', ', $this->fields[$field]);                        // Call the function that corresponds to the rule                        if (!empty($rule))                            $result = $this->$rule($this->fields[$field], $param);                                                        //reCaptcha                            if(isset($_POST['g-recaptcha-response'])&& $_POST['g-recaptcha-response']){  var_dump($_POST);  $secret = "my-secret-key";  $ip = $_SERVER['REMOTE_ADDR'];  $captcha = $_POST['g-recaptcha-response'];  $rsp  = file_get_contents("http://bit.ly/1GJIZSX");  var_dump($rsp);  $arr = json_decode($rsp,TRUE);   if($arr['success']){ echo 'Done'; }  else{   echo 'SPam';  } }                        // Handle errors                        if ($result === false)                            $this->set_error($field, $rule);                    }                }            }                                    if (empty($this->error_list))            {                if ($this->is_xhr)                    echo json_encode(array('status' => 'success'));                $this->process();            }            else            {                if ($this->is_xhr)                    echo json_encode(array('status' => 'invalid', 'errors' => $this->error_list));                else echo $this->error_list;            }        }    }    function process()    {         /**         * SUCCESS!!         * There were no errors in the form.

YOU MUST UNCOMMENT THE CODE FOR IT TO WORK.         *    - This means removing the '//' in front of each line.         *    - If you do not know what php comments are see here: http://bit.ly/1cY6gCF *         * 2. YOU CAN ENTER ANY EMAIL ADDRESS IN THE $from VARIABLE.         *    - This is the address that will show in the From column in your mail application.         *    - If your form contains an email field, and you want to use that value as the $from variable, you can set $from = $this->fields['name of your email field'];         *         * 3. FILE ATTACHMENTS         *    - As stated in the description on codecanyon, this code does not mail attachments. Google 'php html email attachments' for information on how to do this         *         *  4. REDIRECTING TO ANOTHER PAGE AFTER SUBMISSION         *    - This is an ajax enabled form, so you need to perform the redirection in main.js AND this php file.         *      a. Please see instructions in main.js for redirection. This is for users without JS.         *      b. Replace the relevant code below with the page you would like to redirect to.
