This article mainly introduces the method of realizing paging custom styles in thinkPHP3.2, and analyzes the modification and use of thinkPHP3.2 for the underlying framework code in the form of examples. Friends in need can refer to the following

The example in this article describes how thinkPHP3.2 implements paging custom styles. Share it with everyone for your reference, the details are as follows:

The following is a custom paging for Tp3.2. This method was inspired to write this after reading a netizen's blog. After some modifications, you can also modify the custom style after seeing the code;

The main style control file is page.css, and the paging class at the bottom of the framework can be directly pasted and copied;

1. The page.class.php path at the bottom of the framework (Engine\Library\Think)

In fact, this file does not need to be modified too much, you can also use the official one directly; The following is what I use now, with slight modifications;

<?php
namespace Think;
class Page{
  public $firstRow; // 起始行数
  public $listRows; // 列表每页显示行数
  public $parameter; // 分页跳转时要带的参数
  public $totalRows; // 总行数
  public $totalPages; // 分页总页面数
  public $rollPage  = 11;// 分页栏每页显示的页数
  public $lastSuffix = true; // 最后一页是否显示总页数
  private $p    = &#39;p&#39;; //分页参数名
  private $url   = &#39;&#39;; //当前链接URL
  private $nowPage = 1;
  // 分页显示定制
  private $config = array(
    &#39;header&#39; => &#39;<span class="rows">共 %TOTAL_ROW% 条记录</span>&#39;,
    &#39;prev&#39;  => &#39;<<&#39;,
    &#39;next&#39;  => &#39;>>&#39;,
    &#39;first&#39; => &#39;1...&#39;,
    &#39;last&#39;  => &#39;...%TOTAL_PAGE%&#39;,
    &#39;theme&#39; => &#39;%FIRST% %UP_PAGE% %LINK_PAGE% %DOWN_PAGE% %END%&#39;,

2. Controller, just write a demo.

public function index(){
    $obj=M("news");
    $count = $obj->where(&#39;status=1 and classID=74 &#39;)->count();// 查询满足要求的总记录数
    $limit = 10;
    $Page = new \Think\Page($count,$limit);// 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
    $list = $obj->where(&#39;status=1 and classID=74 &#39;)->order(&#39;writetime desc&#39;)->limit($Page->firstRow.&#39;,&#39;.$Page->listRows)->select();
    $firstlist = $obj->where(&#39;status=1 and classID=74 and Indexfirst=1&#39;)->order(&#39;writetime desc&#39;)->limit(4)->select();
    $this->assign(&#39;firstlist&#39;,$firstlist);
    $this->assign(&#39;page&#39;,$show);// 赋值分页输出
    $this->assign(&#39;list&#39;,$list);
    $this->display();
}

3. Next is the View layer, style control. page.css file

.b-page {
 background: #fff;
 box-shadow: 0px 1px 2px 0px #E2E2E2;
}
.page {
 width: 100%;
 background: #FFF;
 text-align: center;
 overflow: hidden;
 font-size:14px;
 margin-top:50px;
}
.page .first,
.page .prev,
.page .current,
.page .num,
.page .current,
.page .next,
.page .end {
 padding: 8px 16px;
 margin: 0px 5px;
 display: inline-block;
 color: #144970;
 border: 1px solid #F2F2F2;
 border-radius: 5px;
}
.page .first:hover,
.page .prev:hover,
.page .current:hover,
.page .num:hover,
.page .current:hover,
.page .next:hover,
.page .end:hover {
 text-decoration: none;
 background: #F8F5F5;
}
.page .current {
 background-color: #144970;
 color: #FFF;
 border-radius: 5px;
}
.page .current:hover {
 text-decoration: none;
 background: #144970;
}
.page .not-allowed {
 cursor: not-allowed;
}
