thinkphp怎么把数据库中的列的值存到下拉框中

    $project = M("project");
    $cell = $project->where(array('status'=>1))->order("id desc")->select();
    //var_dump($cell);
    $this->assign('cell',$cell);

 <select class="test" style="width:88%;height:35px;border-style:none;color:#767676;" id="projectno" name="projectno">       
               <option>&nbsp请输入您的所在小区</option>
                <volist name="cell" id="vo">
                   <option value="{$vo['id']}">{$vo['name']}</option>
                </volist>
 </select>
