'.anchor('crud/editcrud/'.$record->id,'edit').' '.anchor('crud/delete/'.$record->id,'delete')                 );         }          $data['table'] = $this->table->generate();          $this->load->view('crudlist',$data);     }

here model:

    public function count_all()     {         return $this->db->count_all('test');     }     public function get_all_data()     {         return $this->db->get('test')->result();     }     public function get_paged_list($limit, $offset)     {         return $this->db->get('test', $limit, $offset)->result();     }

here view:

    <div>     <h1>simple crud application</h1>     <div><?php echo $pagination;?></div>     <?php echo form_open('crud/index');?>     <select name="limit" onchange="form.submit()">         <option value="1" <?php if ($limit == 1){ echo "selected='selected'";} ?>>1</option>         <option value="2" <?php if ($limit == 2){ echo "selected='selected'";}?> >2</option>         <option value="4" <?php if ($limit == 4){ echo "selected='selected'";}?> >4</option>     </select>     <?php echo form_close();?>     <div><?php echo $table; ?></div>     <br />     <?php echo anchor('crud/addcrud','add crud'); ?> </div>

$post not defined, , mean $_post, can used $this->input->post(). replace:

if (!empty($post['limit'])) {

it should be:

if (!empty($this->input->post('limit'))) {
