Paging display of tp frame (why is the html page directly displaying {$page})

Backstage

1. Paging using the Page class and limit method 

$User = M('User'); // 实例化User对象
$count      = $User->where('status=1')->count();// 查询满足要求的总记录数
$Page       = new \Think\Page($count,25);// 实例化分页类 传入总记录数和每页显示的记录数(25)
$show       = $Page->show();// 分页显示输出
// 进行分页数据查询 注意limit方法的参数要使用Page类的属性
$list = $User->where('status=1')->order('create_time')->limit($Page->firstRow.','.$Page->listRows)->select();
$this->assign('list',$list);// 赋值数据集
$this->assign('page',$show);// 赋值分页输出
$this->display(); // 输出模板

2. Implementation of paging class and page method

$User = M('User'); // 实例化User对象
// 进行分页数据查询 注意page方法的参数的前面部分是当前的页数使用 $_GET[p]获取
$list = $User->where('status=1')->order('create_time')->page($_GET['p'].',25')->select();
$this->assign('list',$list);// 赋值数据集
$count      = $User->where('status=1')->count();// 查询满足要求的总记录数
$Page       = new \Think\Page($count,25);// 实例化分页类 传入总记录数和每页显示的记录数
$show       = $Page->show();// 分页显示输出
$this->assign('page',$show);// 赋值分页输出
$this->display(); // 输出模板

3. Bring in query conditions

If it is a POST query, how to ensure that the original query conditions can be maintained after paging? We can pass in parameters to the paging class by assigning a value to the parameter property of the paging class 

$count      = $User->where($map)->count();// 查询满足要求的总记录数
$Page       = new \Think\Page($count,25);// 实例化分页类 传入总记录数和每页显示的记录数
//分页跳转的时候保证查询条件
foreach($map as $key=>$val) {
    $Page->parameter[$key]   =   urlencode($val);
}
$show       = $Page->show();// 分页显示输出

Front desk

<ul class="paginList pager"><!-- 分页显示 -->{$page}</ul>

If the front desk directly displays

          {$page}

Another way

<ul class="paginList pager">
<!-- 分页显示 -->
<?php
    echo $page;
?>

</ul>
