html

 

public function index()
    {
        try{
        $pagesize = 10;
        $Teacher = new Teacher;
        //$Teachers = $Teacher->select();

        //echo ‘<br />‘;
        //return $teacher->getData(‘name‘);
        $this->assign(‘Teachers‘,$Teachers);//像视图传递数据
        //取回打包后的数据
        $htmls = $this->fetch();
        //将数据返回给用户
        return $htmls;
        }catch(\think\Exception\httpResponseException $e){
            throw $e;
        }catch(\Exception $e){
            return $e->getMessage();
        }    
    }

PHP 

 

最开始是上面那样的方法  

 

解决方案：

 <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>序号</th>
                    <th>姓名</th>
                    <th>性别</th>
                    <th>邮箱</th>
                    <th>用户名</th>
                    <th>操作</th>
                </tr>
        {volist name="Teachers" id="Teachers" key="key"}
            <tr>
                    <td>{$key}</td>
                <td>{$Teachers->getData(‘name‘)}</td>
                <td>{eq name=‘$Teachers->getData("sex")‘ value=http://www.mamicode.com/‘0‘}男{else /}女{/eq}</td>
                <td>{$Teachers->getData(‘email‘)}</td>
                <td>{$Teachers->getData(‘username‘)}</td>
                <td><a href="{:url(‘edit?id=‘.$Teachers->getData(‘id‘))}">编辑&nbsp;&nbsp;</a>
                <a href="{:url(‘delete?id=‘.$Teachers->getData(‘id‘))}">删除</a></td>
            </tr>
        {/volist}
                </table>
                当前页总条数{$Teachers->count()}
                {$page}
       </div>

PHP 

public function index()
    {
        try{
        $pagesize = 10;
        $Teacher = new Teacher;
        //$Teachers = $Teacher->select();
        $Teachers = $Teacher->paginate($pagesize);
        $page = $Teachers->render(); 
　　　　//调用render（）方法   新添加的这里  
       // $teacher = $Teachers[0];
        //var_dump($teacher->getData());
        //echo ‘<br />‘;
        //echo $teacher->getData(‘name‘);
        //echo ‘<br />‘;
        //return $teacher->getData(‘name‘);
        $this->assign(‘Teachers‘,$Teachers);//像视图传递数据
        $this->assign(‘page‘,$page);//这里要重新传递一下  
        $htmls = $this->fetch();
        //将数据返回给用户
        return $htmls;
        }catch(\think\Exception\httpResponseException $e){
            throw $e;
        }catch(\Exception $e){
            return $e->getMessage();
        }    
    }//千锋PHP-PHP培训的实力派
