$id = $this->uri->segment(3);
$data['students'] = $this->delete_model->show_students();
$data['single_student'] = $this->delete_model->show_student_id($id);
$this->load->view('delete_view', $data);
}

// Function to select particular record from table name students.
function show_student_id($data){
$this->db->select('*');
$this->db->from('students');
$this->db->where('student_id', $data);
$query = $this->db->get();
$result = $query->result();
return $result;
