issue getting the edit page to display in Codeigniter

Question

For some reason I cannot for the life of me get the edit page to display. Not sure what I am doing wrong I went through the code so many times. When I click to edit a record the page is blank and no error messages come up.

here is the code for the model which I think is why it is causing an issue.

public function update_employee($data,$id)
    {
        $this->db->where('id',$id);
        $this->db->update('employee_list',$data);
        return ($this->db->affected_rows() != 1 ) ? false:true;
    }
}

Here is the code for the contoller

public function  update_employee()
    {
        $id=$this->input->post('id');

        $data=array('Employee_Name'=>$this->input->post('Employee_Name'),

            'Employee_Number'=>$this->input->post('Employee_Number'));


        $result=$this->employee_model->update_employee($data); 
if($result > 0) 
        {
            $this->session->set_flashdata('msg',"Employee Records Updated Successfully");
            redirect('employee/list_employees');

        }
        else
        {

            $this->session->set_flashdata('msg1',"No changes Made in Employee Records");
            redirect('employee/list_employees');


        }
    }

Answer 1

I replaced return ($this->db->affected_rows() != 1 ) ? false:true; with return print_r($data); and now it works
