class pages extends CI_Controller {

    function view($page = 'index') {

        $this->load->view('pages/index');

        function insert_data() {
            $this->load->model('contact_model');
            $this->contact_model->insert_entry();
        }

    }

}

?>

this is my view view/pages/index.php

<form id="submit">

    name <input  type="text" id="name" >    

    email<input type="email" id="email">


    message<textarea id="message"></textarea>              

    <button type="button"  id="submit1">Send</button>
    <a id="ack"></a>         
</form>

this is my model models/contact_model

<?php

class contact_model extends CI_Model {

    function insert_entry() {
        $data = array(
            'name' => 'name',
            'email' => 'email',
            'message' => 'message');

        $this->db->insert('contactus', $data);
    }
?>

this is my custom.js file

$.ajax({
    url: "<?php echo site_url();?>/pages/insert_data",
    type: 'POST',
    data: {"name": $("#name").val(), "email": $("#email").val(), "message": $("#message").val()},
    success: function(data) {
        $("div#ack").html(data);
    }
});

Answer 1

First remove your insert_data function from your view function, and add it independently from that, and get the posts and pass them to your model like this:

class pages extends CI_Controller {

    function view($page = 'index') {
        $this->load->view('pages/index');
    }

    function insert_data(){
        $data = array(
            'name' =>  $this->input->post('name'),
            'email' => $this->input->post('email'),
            'message' => $this->input->post('message')
        );
        $this->load->model('contact_model');
        $this->contact_model->insert_entry($data);
        echo json_encode($data);
    }

}

Change your model as below:

class contact_model extends CI_Model {

    function insert_entry($data) {
        $this->db->insert('contactus', $data);
    }

}

Add on click event to your javascript:

$("#submit1").on('click',function(){
     $.ajax({
         url: "<?php echo site_url('pages/insert_data');?>",
         type: 'POST',
         data: {"name": $("#name").val(), "email": $("#email").val(), "message": $("#message").val()},
         success: function(data) {
             $("#ack").html(data); // change here too
         }
     });
 });
