In controller i have feedback.php with this code

 <?php
class feedback_model extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('feedback_model');
}
function index()
{
// Including Validation Library



// Setting Values For Tabel Columns
$data = array(
'complain_id' => $this->input->post('complain_id'),
'email' => $this->input->post('email'),
'response1' => $this->input->post('Qustion1'),
 'response1' => $this->input->post('Question2'),
 'response1' => $this->input->post('Question3'),
 'response1' => $this->input->post('Question4')

);
// Transfering Data To Model
$this->insert_model->form_insert($data);
// Loading View
$this->load->view('feedback');
}
}
?>

And in model i have feedback_model.php with this code.

<?php
class feedback_model extends CI_Model{
function __construct() {
parent::__construct();
}
function form_insert($data){
// Inserting in Table(feedback) of Database(college)
$this->db->insert('feedback', $data);
}
}
?>

Solution

I created same something like yours

First is you need to setup your project properly Like Database Connection, Autoloaded Helpers of CI

Here is my feedback.php controller

<?php

class feedback extends CI_Controller {

    function __construct() {

        parent::__construct();

        $this->load->model('feedback_model');
    }

    function index() {
        
        // Loading View
        $this->load->view('feedback');
    }

    function submit() {

        // check for method
        if ($this->input->post('REQUEST_METHOD') == 'POST') {

            // Including Validation Library
            // Setting Values For Tabel Columns
            $data = array(
                'response1' => $this->input->post('Qustion1'),
                'response2' => $this->input->post('Question2')
            );

            // Transfering Data To Model
            $this->feedback_model->form_insert($data);
        }

        
    }
}

Here is my feedback_model.php nothings really change with yours

<?php

class feedback_model extends CI_Model{

    function form_insert($data){
        // Inserting in Table(feedback) of Database(college)
        $this->db->insert('feedback', $data);
    }
}

Here is the view, named as feedback.php under the folder views

<html>
  <head>
    <title></title>
  </head>
  <body>
    <form role="form" method="POST" action="feedback/submit">
      <span class="badge">1</span></a> Is your complain solved ?
      <div class="form-group">
        <div class="radio">
          <label><input type="radio" name="Question1"
          value="yes">Yes</label>
        </div>
        <div class="radio">
          <label><input type="radio" name="Question1" value="no">NO</label>
        </div>
      </div>
      <span class="badge">2</span></a> How easy was it to complain to us?
      <div class="form-group">
        <div class="radio">
          <label><input type="radio" name="Question2" value='excellent'>Excellent</label>
        </div>
        <div class="radio">
          <label><input type="radio" name="Question2" value="good">Good </label>
        </div>
        <div class="radio">
          <label><input type="radio" name="Question2" value="bad">Bad</label>
        </div>
        <div class="radio">
          <label><input type="radio" name="Question2" value="verybad">Very Bad</label>
        </div>
      </div>
      <div class="form-group">
        <input type="submit" value="submit" name="submit">
      </div>
    </form>
  </body>
</html>

In the view i added a attribute

method="POST" and action="feedback/submit"

method means the request type going to the server and action is uri your form being submitted

so in this case the form will be submitted to controller feedback where the method is submit

from the submit method

i check if the request method is post

and get the post data namely the

Question1

Question2

and pass it to the feedback_model

$data = array(
    'response1' => $this->input->post('Qustion1'),
    'response2' => $this->input->post('Question2')
);

// Transfering Data To Model
$this->feedback_model->form_insert($data);

you can modified it according to your need.

and one more thing that is important is the naming conventions for MVC

since you have a controller feedback_model.php then created again a feedback_model.php for model which is confusing.

Hope it help
