After getting the key, we will create a form using the bootstrap and pass the site key.
When the user fills the form data with resolves the reCAPTCHA code that time response token will be returned.
Step 4: Create ControllerIn this step, we will create a Googlerecaptcha.php file in the “application/controller” directory and paste the below code in this controller.application/controller/Googlerecaptcha.php
<?php
class Googlerecaptcha extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper(array('url','form'));
$this->load->library('session');
$this->load->database();
}
public function index()
{
$this->load->view('google_recaptcha_form');
}
public function googleForm()
{
$data = array(
'first_name' => $this->input->post('first_name'),
'last_name' => $this->input->post('last_name'),
'address' => $this->input->post('address'),
'email' => $this->input->post('email'),
'mobile' => $this->input->post('mobile')
);
$recaptchaResponse = trim($this->input->post('g-recaptcha-response'));
$userIp=$this->input->ip_address();
$secret='ENTER_YOUR_SECRET_KEY';
$response = json_decode(file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret=".$secret."&response=".$recaptchaResponse."&remoteip=".$userIp), true);
if($response['success'] == false)
{
$this->session->set_flashdata('message', 'Sorry Google Recaptcha Unsuccessful!!');
}
else
{
echo '<h2>Thanks for posting comment.</h2>';
$this->db->insert('users',$data);
$this->session->set_flashdata('message', 'Google Recaptcha Successful');
}
redirect(base_url('googlerecaptcha'));
}
}
?>Step 5: Create View FileSo finally, we will create the google_recaptcha_form.php file in the “application/views/” directory and make a form with google Recaptcha code in HTML.application/views/google_recaptcha_form.php
