Codeigniter Google Recaptcha Form Validation Example – onlinecode
In this post we will give you information about Codeigniter Google Recaptcha Form Validation Example – onlinecode. Hear we will give you detail about Codeigniter Google Recaptcha Form Validation Example – onlinecodeAnd how to use it also give you demo for it if it is necessary.
In this tutorial, we are going to create the Codeigniter Google Recaptcha Form Validation Example. normally captcha is used for security purpose and only human users can pass through. computers or bots are not solving a captcha.
Now we will learn about captcha that how to integrate the Google reCAPTCHA in Codeigniter. so you can see below google captcha code form Validation with Codeigniter.
Overview
Step 1: Create a Database in tableStep 2: Connect to DatabaseStep 3: Get and Set Google Captcha SecretsStep 4: Create ControllerStep 5: Create View File
Step 1: Create a Database in tableIn this step, we have to create a table in the database, so we will create a database using the below code.
CREATE TABLE IF NOT EXISTS 'register' (
'id' int(11) NOT NULL AUTO_INCREMENT,
'first_name' varchar(64) NOT NULL,
'last_name' varchar(64) NOT NULL,
'address' text NOT NULL,
'email' varchar(64) NOT NULL,
'mobile' varchar(12) NOT NULL,
PRIMARY KEY ('id')
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=15 ;Step 2: Connect to DatabaseGo to the config folder and open database.php file some changes in this file like hostname, database username, database password, and database name.
$db['default'] = array( 'dsn' => '', 'hostname' => 'localhost', 'username' => 'root', 'password' => '', 'database' => 'enter here database name', 'dbdriver' => 'mysqli', 'dbprefix' => '', 'pconnect' => FALSE, 'db_debug' => (ENVIRONMENT !== 'production'), 'cache_on' => FALSE, 'cachedir' => '', 'char_set' => 'utf8', 'dbcollat' => 'utf8_general_ci', 'swap_pre' => '', 'encrypt' => FALSE, 'compress' => FALSE, 'stricton' => FALSE, 'failover' => array(), 'save_queries' => TRUE );
Step 3: Get and Set Google Captcha SecretsFirst, we need to Google reCAPTCHA site key and secret key. so first we go to Google reCAPTCHA panel and get site key and secret key.
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
