Admin.php in the model file
<?php namespace app\admin\model; use think\Model; class Admin extends Model{ }
lst.html
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>后台</title> <style type="text/css"> *{ padding: 0; margin: 0; } table{ width: 500px; margin: auto; } .pagination li{ margin: 10px; float: left; list-style: none; } </style> </head> <body> <p>我是lst</p> <a href="{:url('admin/add')}" rel="external nofollow" >跳转add</a> <table border="1" cellspacing="" cellpadding=""> <tr> <th>ID</th> <th>用户名</th> <th>操作</th> </tr> <!-- 循环数据 --> {volist name="list" id="vo"} <tr> <td>{$vo.id}</td> <td>{$vo.username}</td> <td>Data</td> </tr> {/volist} </table> <!-- 分页器 --> {$list ->render()} </body> </html>
