In this paper, an example is given to illustrate the method of implementing paging custom style in thinkPHP 3.2. Share it for your reference, as follows:

The following is a custom paging of Tp 3.2, which was inspired by 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 document does not need to be modified too much, and it can also be directly used by the official; The following is what I use now, with slight modifications; 


<?php
namespace Think;
class Page{
  public $firstRow; //  Number of starting lines 
  public $listRows; //  List rows per page 
  public $parameter; //  Parameters to take when paging jump 
  public $totalRows; //  Total number of rows 
  public $totalPages; //  Total number of paged pages 
  public $rollPage  = 11;//  Pages per page displayed in the paging bar 
  public $lastSuffix = true; //  Finally 1 Whether the page displays the total number of pages 
  private $p    = 'p'; // Paging parameter name 
  private $url   = ''; // Current link URL
  private $nowPage = 1;
  //  Paging display customization 
  private $config = array(
    'header' => '<span class="rows"> Altogether  %TOTAL_ROW%  A record </span>',
    'prev'  => '<<',
    'next'  => '>>',
    'first' => '1...',
    'last'  => '...%TOTAL_PAGE%',
    'theme' => '%FIRST% %UP_PAGE% %LINK_PAGE% %DOWN_PAGE% %END%',
  );
  /**
   *  Schema function 
   * @param array $totalRows  Total number of records 
   * @param array $listRows  Number of records displayed per page 
   * @param array $parameter  Parameters of paging jump 
   */
  public function __construct($totalRows, $listRows=20, $parameter = array()) {
    C('VAR_PAGE') && $this->p = C('VAR_PAGE'); // Set the paging parameter name 
    /*  Basic settings  */
    $this->totalRows = $totalRows; // Set the total number of records 
    $this->listRows  = $listRows; // Set the number of rows per page 
    $this->parameter = empty($parameter) ? $_GET : $parameter;
    $this->nowPage  = empty($_GET[$this->p]) ? 1 : intval($_GET[$this->p]);
    $this->firstRow  = $this->listRows * ($this->nowPage - 1);
  }
  /**
   *  Customize paging link settings 
   * @param string $name  Set name 
   * @param string $value  Setting value 
   */
  public function setConfig($name,$value) {
    if(isset($this->config[$name])) {
      $this->config[$name] = $value;
    }
  }
  /**
   *  Generate Link URL
   * @param integer $page  Page number 
   * @return string
   */
  private function url($page){
    return str_replace(urlencode('[PAGE]'), $page, $this->url);
  }
  /**
   *  Assemble paging links 
   * @return string
   */
  public function show() {
    if(0 == $this->totalRows) return '';
    /*  Generate URL */
    $this->parameter[$this->p] = '[PAGE]';
    $this->url = U(ACTION_NAME, $this->parameter);
    /*  Calculate paging information  */
    $this->totalPages = ceil($this->totalRows / $this->listRows); // Total pages 
    if(!empty($this->totalPages) && $this->nowPage > $this->totalPages) {
      $this->nowPage = $this->totalPages;
    }
    /*  Calculate paging zero time variable  */
    $now_cool_page   = $this->rollPage/2;
    $now_cool_page_ceil = ceil($now_cool_page);
    $this->lastSuffix && $this->config['last'] = $this->totalPages;
    // Upper 1 Page 
    $up_row = $this->nowPage - 1;
    $up_page = $up_row > 0 ? '<a class="prev" href="' . $this->url($up_row) . '" rel="external nofollow" >' . $this->config['prev'] . '</a>' : '';
    // Under 1 Page 
    $down_row = $this->nowPage + 1;
    $down_page = ($down_row <= $this->totalPages) ? '<a class="next" href="' . $this->url($down_row) . '" rel="external nofollow" >' . $this->config['next'] . '</a>' : '';
    // No. 1 1 Page 
    $the_first = '';
    if($this->totalPages > $this->rollPage && ($this->nowPage - $now_cool_page) >= 1){
      $the_first = '<a class="first" href="' . $this->url(1) . '" rel="external nofollow" >' . $this->config['first'] . '</a>';
    }
    // Finally 1 Page 
    $the_end = '';
    if($this->totalPages > $this->rollPage && ($this->nowPage + $now_cool_page) < $this->totalPages){
      $the_end = '<a class="end" href="' . $this->url($this->totalPages) . '" rel="external nofollow" >' . $this->config['last'] . '</a>';
    }
    // Digital connection 
    $link_page = "";
    for($i = 1; $i <= $this->rollPage; $i++){
      if(($this->nowPage - $now_cool_page) <= 0 ){
        $page = $i;
      }elseif(($this->nowPage + $now_cool_page - 1) >= $this->totalPages){
        $page = $this->totalPages - $this->rollPage + $i;
      }else{
        $page = $this->nowPage - $now_cool_page_ceil + $i;
      }
      if($page > 0 && $page != $this->nowPage){
        if($page <= $this->totalPages){
          $link_page .= '<a class="num" href="' . $this->url($page) . '" rel="external nofollow" >' . $page . '</a>';
        }else{
          break;
        }
      }else{
        if($page > 0 && $this->totalPages != 1){
          $link_page .= '<span class="current">' . $page . '</span>';
        }
      }
    }
    // Replace paging content 
    $page_str = str_replace(
      array('%HEADER%', '%NOW_PAGE%', '%UP_PAGE%', '%DOWN_PAGE%', '%FIRST%', '%LINK_PAGE%', '%END%', '%TOTAL_ROW%', '%TOTAL_PAGE%'),
      array($this->config['header'], $this->nowPage, $up_page, $down_page, $the_first, $link_page, $the_end, $this->totalRows, $this->totalPages),
      $this->config['theme']);
    return "<div>{$page_str}</div>";
  }
}

2. Controller, just write demo. 


public function index(){
    $obj=M("news");
    $count = $obj->where('status=1 and classID=74 ')->count();//  Query the total number of records that meet the requirements 
    $limit = 10;
    $Page = new \Think\Page($count,$limit);//  Instantiate the paging class   Total number of incoming records and number of records displayed per page (25)
    $show    = $Page->show();//  Paged display output 
    $list = $obj->where('status=1 and classID=74 ')->order('writetime desc')->limit($Page->firstRow.','.$Page->listRows)->select();
    $firstlist = $obj->where('status=1 and classID=74 and Indexfirst=1')->order('writetime desc')->limit(4)->select();
    $this->assign('firstlist',$firstlist);
    $this->assign('page',$show);//  Assignment paging output 
    $this->assign('list',$list);
    $this->display();
}

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


.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;
}
