how to insert from data using ajax in codeigniter?

step 1) in test.php load db

public function __construct(){    parent::__construct();    $this->load->database();}

step 2) modify

$this->db->insert('contact',$data);  if($status['success'])  {    // code  }

to

if($this->db->insert('contact',$data)){  //rest of code}

it should work

change in controller

note: please read commented line for better undersatnding

public function signin(){    if($this->input->post('insert'))    {        $name = trim($this->input->post('name'));        $email = trim($this->input->post('email'));        $phone = trim($this->input->post('phone'));        $message = trim($this->input->post('message'));        $s_data = date('Y-m-d');        $data = array(                    'name' => $name,                    'email' => $email,                    'phone' => $phone,                    'message' => $message,                    's_date' => $s_date                    );         $recaptchaResponse = trim($this->input->post('g-recaptcha-response'));        $userIp=$this->input->ip_address();        $secret='****************************';        $url="https://www.google.com/recaptcha/api/siteverify?secret=".$secret."&response;=".$recaptchaResponse."&remoteip;=".$userIp;        $response = $this->curl->simple_get($url);        $status= json_decode($response, true);        if($status['success'])        {            //insert data when get success in google recaptcha          $this->db->insert('contact',$data);             $res['msg']="successfull";          //no need to set flash session in CI for ajax            //$this->session->set_flashdata('flashSuccess', 'successfull');        }        else        {            //$this->session->set_flashdata('flashSuccess', 'Sorry Google Recaptcha Unsuccessful!!');            $res['msg']="Sorry Google Recaptcha Unsuccessful!!";        }        //set page header as json format        $this->output        ->set_content_type('application/json')        ->set_output(json_encode($res));    }}

change your script

<script>    $(document).ready(function(){        $("#insert").click(function(){            var name = $("#name").val();            var email = $("#email").val();            var phone = $("#phone").val();            var message = $("#message").val();            //pass object in post            var dataString = {'name': name , 'email': email , 'phone': phone , 'message': message};            if(name==''||email==''||phone==''||message=='')            {                alert("Please Fill All Fields");            }            else            {                // AJAX Code To Submit Form.                $.ajax({                    type: "POST",                    url: "<?php echo base_url('index.php/'); ?>test/signin",                    data: dataString,                    dataType: 'json',                    cache: false,                    success: function(result){                        alert(result.msg);                    }                });            }            return false;        });    });</script>
