Hello Friends,
Am actually trying to get a Foreign key which is a Primary key in Diagnosis table

Controller:

<?php
class AppTreatment extends CI_Controller
{
   function AppTreatment()
   {
      parent::__construct();

      $this->view_data['base_url'] = base_url();

      $this->load->model('Apptreatment_model');
      $this->load->model('Patient_model');

      if(!$this->session->userdata('is_logged_in') ){
      $this->session->set_flashdata('login_error', TRUE);
      redirect(base_url() . 'index.php/homepage');
        }


   }

   function index()
   {

    $data['patient']=$this->Patient_model->getAllpatients();
     $data['AppTreatment']=$this->Apptreatment_model->findAll();




    foreach($data['AppTreatment'] as $key => $item)
    {
      $pname=$this->Patient_model->fetchpatientdata($item->P_ID,"First_Name")." ".$this->Patient_model->fetchpatientdata($item->P_ID,"Last_Name");
      $item->P_ID=$pname;

    }

    $data['head_title'] = "Member Area";
      $data['styles'] = array(
        'css/krylov.css', 
        'css/trial.css',
        'css/mws-theme.css',
        'css/button.css',
        'css/mws-style.css',
        'bootstrap/css/bootstrap.min.css',
        'css/fonts/ptsans/stylesheet.css',
        'css/fonts/icomoon/style.css',
        'css/icons/icol32.css',
        'css/fonts/icomoon/style.css',
        'jui/css/jquery.ui.all.css',
        'jui/jquery-ui.custom.css',
        'css/themer.css'
      );

      $data['scripts']= array(
          'js/AppTreatment.js'
      );

        $this->load->library('form_validation');

        $this->form_validation->set_rules('Date' , 'date', 'trim|required|xss_clean');

        if ($this->form_validation->run() == FALSE)
        {
          //hasn't been run or there are validation errors

          //$this->render->view($this->view_data, 'diagnosis_view');
          $this->render->view($data, 'AppTreatment_view');
        }

        else
        {
          // everything is good - process the form - write the data into the database


        $Date = $this->input->post('Date'); 
        $Time = $this->input->post('Time'); 
        $Diagnosis_ID = $this->input->post('diagnosis');

        $this->Apptreatment_model->register_AppTreatment($Date, $Time, $Diagnosis_ID);



         echo "Appointment for Treatment is added succesfully in the database";

      }      
      //$this->load->view('view_appointmentForm',$data);

  }

    //$this->view_data['patient'] = $data['patient'];

    //$this->register();


  function getdiagnosis()
  {

    $this->load->model('Apptreatment_model');
    $P_ID = $this->input->post('patient_selected');

    $AppTreatments = $this->Apptreatment_model->patientAppTreatment($P_ID);

    if($AppTreatments != FALSE){
      $options = array(
        0 =>  'Please Select'
      );
      foreach ($AppTreatments as $key => $value) {
        $options[$value->Diagnosis_ID] = $value->Diagnosis_Name;
      }

      //$string=$this->load->view('getappointment', $data['appointment'], true);


      echo form_dropdown('diagnosis', $options, 0);
    }
    else{
      //no diagnosis for that patient
      echo FALSE;
    }
   }

 }


The model:
<?php

class Apptreatment_model extends CI_Model {


function Apptreatment_model()
{

    parent::__construct();

}   

function register_Apptreatment($Date, $Time, $Diagnosis_ID)
{

    $query_str = "INSERT INTO treatment(Date,Time,Diagnosis_ID) VALUES (?, ?, ?)" ; 

    $this->db->query($query_str,array($Date, $Time, $Diagnosis_ID));
}

public function findAll()
    {
        $query=$this->db->get('treatment');

        return $query->result();
    }



function getdiagnosis()
{
    $query = $this->db->get_where('patient', array('id' => $P_ID), $limit, $offset);

}




function patientAppTreatment($P_ID)
{
$this->db->select('*');
        $this->db->from('appointment');
        $this->db->join('diagnosis', 'diagnosis.App_ID = appointment.Appointment_ID');
        $this->db->where('appointment.P_ID', '$P_ID');
        $q = $this->db->get();

    if($q->num_rows() > 0){
        return $q->result();
    }
    else{
        return FALSE;
    }

}



}


The ajax part:

(function($){



    function get_diagnosis() {
        var patient_selected = $('#P_ID').val();
        $.ajax({
            data: {
                patient_selected: patient_selected,
            },
            type: 'POST',
            url: 'http://localhost/Clinic/index.php/AppTreatment/getdiagnosis',
            success: function(data){
                //console.log(data);
                $('#ApptreatmentsLI').show();

                if(data != false){
                    $('#AppTreatments').html(data);
                }
                else{
                    $('#AppTreatments').html('No Diagnosis');   
                }
            }
        })
    }

    $(function(){
        $('#P_ID').change(function(){
            get_diagnosis();
        });    
    });


})(jQuery);



The view:

<?php



echo  form_open($base_url . 'index.php/AppTreatment');


$Date=array(
    'name'      =>  'Date',
    'id'        =>  'Date',
    'type'      =>   'date'

);


$Time=array(
    'name'      =>  'Time',
    'id'        =>  'Time',
    'type'      =>   'time'


);



?>


<div class="mws-panel grid_8">

    <div class="mws-panel-header">
        <span><i class="icon-magic"></i>Treatment Appointment  Form</span>
    </div>



    <div class="mws-panel-body no-padding">

            <fieldset class="wizard-step mws-form-inline">

                <ul>
<li>
        <label class="adjust">Patient</label>
        <div>
        <select name="P_ID" id="P_ID">
        <option>--Select Patient--</option>
        <?php

            foreach($patient as $item)
            {
            ?>
                <option value="<?php echo $item->Patient_ID?>"><?php echo $item->First_Name." ".$item->Last_Name?></option>
            <?php
            }

        </select>

                  <div>
                   <label class="adjust">Treatment Time</label>
                   <?php echo form_input($Time); ?>
                 </div>
                 </li>





                    <li>
                        <?php echo validation_errors(); ?>
                    </li>   


                    <div>
                        <?php echo form_submit(array('name' => 'register'), 'Create');  ?>
                    </div>
                    </li>

            </ul>
        </fieldset>

    </div>
</div>
</form>

You have made the script more complecated by adding ajax. Intially try to fetch the foriegn key using only php. Then pass that value to ajax.
