Access values based on dropdown value.

Hello,

I have students database from which I want to access students data based on class section, when any section is selected from dropdown list.

For I tried below:

my jquery is below, where sections is my dropdown id.

Code:

$("#sections").change(function(){
      var sectionid = $(this).val();
      $.ajax({
        url: "<?php echo $baseurl; ?>/Students/getStudents",
        type: "POST",
        data:{sectionid:sectionid},
        success:function(data)
        {
      // $("#session").find('option').not(':first').remove();
         // $("#sections").html(data);
        }
      });
    });

getStudents function in controller Students is below:

PHP Code:

public function getStudents()
    {
        $model =new StudentModel();
        if($this->request->getVar('sectionid'))
        {
            $id = $this->request->getVar('sectionid');
          return $model->getStudents($id);   
        }      
    } 


and the  getStudents function with param function in StudentModel is:

PHP Code:

public function getStudents($id)
    {
       $sectionid = $id;
       $sql = "SELECT s.*, e.* FROM tblstudents s INNER JOIN tblenrollment e ON s.id = e.studentid WHERE e.sectionid=?";
       $query = $this->db->query($sql,$sectionid);
       $results = $query->getResult();
       return $results;
    } 


now my problem is to retrieve these values in my view

I tried like below, but it requires parameter, please help.

PHP Code:

$data['students'] = $model->getStudents();
