html

 

public function index()
    {
        try{
        $pagesize = 10;
        $Teacher = new Teacher;
        //$Teachers = $Teacher->select();
        $Teachers = $Teacher->paginate($pagesize);
       // $teacher = $Teachers[0];
        //var_dump($teacher->getData());

        //echo $teacher->getData('name');
        //echo '<br />';
        //return $teacher->getData('name');
        $this->assign('Teachers',$Teachers);//像視圖傳遞數據
        //取回打包后的數據
        $htmls = $this->fetch();
        //將數據返回給用戶
        return $htmls;
        }catch(\think\Exception\httpResponseException $e){
            throw $e;
        }catch(\Exception $e){
            return $e->getMessage();
        }    
    }

PHP 

 

最開始是上面那樣的方法  

 

解決方案：

 <div class="col-md-12">
            <hr />
            <a href="{:url('add')}" class="btn btn-primary"><i class="glyphicon glyphicon-plus"></i>&nbsp;增加</a>
            <hr />
            <table class="table table-hover table-bordered">
                <tr class="info">
                    <th>序號</th>
                    <th>姓名</th>
                    <th>性別</th>
                    <th>郵箱</th>
                    <th>用戶名</th>
                    <th>操作</th>
                </tr>
        {volist name="Teachers" id="Teachers" key="key"}

            </tr>
        {/volist}
                </table>
