答

Don't Write query directly in controller. This is bad use of MVC. You can write your query in model file.

Your code not fetching data from database

Controller

function edit()
{
    $id =  $this->input->get('id');
    $this->db->where('id',$id);
    $data['data'] = $this->model_name->get_data($id);// call your model file and pass result in data variable
    $data['id'] = $id;
    $data['title'] = "Welcome to DB";
    $data['results'] = $this->category_model->getAll();
    $this->load->view('category', $data);
}

Model

function get_data($id)
{
     $this->db->where('id',$id);

     $query=$this->db->get('categort_tbl');
     return $query->row();// fetch row and return from model
 }

Views

<tr>
<td width="9%">Category :</td>
<td width="21%"><input type="text" name="category" required=""  size="40" value="<?php echo $data->category;?>"/></td>
<td width="48%"><input type="submit" class="submit_button" name="save" value="Save"/></td>
</tr>
