本文介绍了一种使用PHP实现教师信息列表分页显示的方法，包括如何通过paginate方法获取分页数据并将其传递到视图中进行展示。

复制代码
{volist name="Teachers" id="Teachers" key="key"}
<tr>
<td>{$key}</td>
<td>{$Teachers->getData('name')}</td>
<td>{eq name='$Teachers->getData("sex")' value='0'}男{else /}女{/eq}</td>
<td>{$Teachers->getData('email')}</td>
<td>{$Teachers->getData('username')}</td>
<td><a href="{:url('edit?id='.$Teachers->getData('id'))}">编辑  </a>
<a href="{:url('delete?id='.$Teachers->getData('id'))}">删除</a></td>
</tr>
{/volist}
</table>
当前页总条数{$Teachers->count()}
{$Teachers->render()}
</div>

上面是 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 '<br />';
//echo $teacher->getData('name');
//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();
}
}

上面是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> 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='$Teachers->getData("sex")' value='0'}男{else /}女{/eq}</td>
<td>{$Teachers->getData('email')}</td>
<td>{$Teachers->getData('username')}</td>
<td><a href="{:url('edit?id='.$Teachers->getData('id'))}">编辑  </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();
}
