AngularJS | How to Send the Data of Json to databa

I am trying to use Angular.

I am trying to Post Form of Angular, which have been done successfully, it is posting in JSON, But Problem is it only Post the input fields which have values, if i have NOT filled a textbox then it will NOT post that textbox value and fieldname, so how to know in controller which input fields have been posted.

Also how to send it to the model??

Here what i have done so far.

View.

    </form>
    </div>
    <script>
       function controller ($scope,$http)
       {
           var angularform="<?php echo base_url(); ?>index.php/datacon/angform"
           $scope.save=function()
           {
            $http.post(angularform, $scope.user);
           }
       }
    </script>
    </body>
</html>

Controller:

public function angform()
    {
        $get=file_get_contents('php://input');
        $json_get=json_decode($get);
        foreach($json_get as $key=>$value){
         // i think something it has to do here.
        }

        $this->load->model('datamodel');
        $this->datamodel->insert($data);
        }

here is the screenshot, i have filled three fields so it posted the values of three fields only.

        $json_get=json_decode($get);
        foreach($json_get as $key=>$value){              
         $data[$key]=$value; //Worked For Me.
        }

        $this->load->model('datamodel');
        $this->datamodel->insert($data);
        }

i check like this :-

 if($this->input->get_post('male'))
    {
     // rest code goes here
    }

Change your input name to match exactly like the database attribute(column) name. In that way you will not have to check anything:

$data = $this->input->post(null);    #get the post array
$this->db->insert('table', $ata);
