codeigniter - codeignaitor のエラー更新行

Question

行をデータベースに更新するとエラーが発生します。

私の問題は、行を更新せず、インデックスで定義されていないファイルのアップロードを更新して写真をアップロードするときに私に電話することです。

私のコントローラー：

public function addedit(){

    $events = new events_model();
    $prodID = $this->input->post('hID');
    $text = $this->input->post('ev_text');
    $pic = $this->do_upload('ev_pic');
    $submit = $this->input->post('submit');

    if($submit){

        if(!empty($prodID)){

            $this->data['events'] = $events->UpdatePost($prodID, $text , $pic );
            $this->data['pagetitle'] = "Show Info";             
            $this->data['success']= "Update Done";

        }else{

            $this->data['success'] = "Add Done";
        }

    $this->data['status'] = "1";

    }else{

        $this->data['status'] = "0";
        $this->data['errors'] = "Error";
    }

    $this->template->build('admin/events/add',$this->data);
}

とモデル:

function UpdatePost($prodID, $text , $pic ) {

    if ($pic == ""){

        $vales = array('ev_id' => $prodID , 'ev_text' => $text);

    }else{

        $vales = array('ev_id' => $prodID , 'ev_text' => $text , 'ev_pic' => $pic);
    }

    $query = $this->db->update($this->table_name, $vales) or die (mysql_error());
    $result = array();
    $result["process"] = "ok";
    echo "1";       
}

とビュー:

<div class="widget-body">

            <table class="data-table" action="./administrator/categories/delete/"><!-- Table Conversion: See Section E in custom.js -->
                <thead>

                    <?php foreach ($events as $n): ?>
                            <tr>

                                <td class="center"><?= $n->ev_date; ?></td>
                                <td>

                    <?php endforeach ?>
                </tbody>

            </table>



            <div class="clear"></div>
        </div>
         <div class="clear"></div>
    </div>

    <div id="table-extra">
        <div id="table-action">
            <input action="./administrator/<?php echo $this->uri->segment(2)."/deleteitems" ?>" class="btn-theme table-button btn-hover-black DeleteItems" id="submit" type="button" value="Delete" />
        </div>
        <div class="paginate">
            <ul>
                <?= $this->pagination->create_links(); ?>
            </ul>
            <div class="clear"></div>
        </div>

        <div class="clear"></div>
    </div>
</div>
</div>

私のコードのどこに問題があり、成功を更新するつもりはありません。
