Detaillierte Erläuterung der Seitenklasse des Thinkphp-Frameworks und des Bootstrap-Paging-Klassencodes

In diesem Artikel werden hauptsächlich die Thinkphp-Framework-Seitenklasse und das Bootstrap-Paging (Verschönerung) vorgestellt. Ich hoffe, es kann jedem helfen.

Schreiben Sie hier den Linkinhalt zur Verwendung von Bootstrap-Stilen

<nav aria-label="Page navigation">
 <ul class="pagination">
  <li>
   <a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" aria-label="Previous">
    <span aria-hidden="true">«</span>
   </a>
  </li>
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >1</a></li>
  <li><a href="#" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" >2</a></li>

    <span aria-hidden="true">»</span>

2. Zugehöriger Controller-Code

  //所有新闻
  public function all_news(){
    $Article=M("Article");
    $where['article_type']=1;
    //查询满足要求的总的记录数
    $count=$Article->where($where)->count();
    //实例化分页类传入总记录数和煤业显示的记录数
    $Page=new \Think\Page($count,1);
    //分页显示输出
    $show=$Page->show();
    // 进行分页数据查询 注意limit方法的参数要使用Page类的属性
    $news=$Article->where($where)->order('pub_time')->field('id,title,institution_type,author_name,pub_time')->limit($Page->firstRow.','.$Page->listRows)->select();
    //赋值数据集
    $this->assign('news',$news);
    //赋值分页输出
    $this->assign('page',$show);
    $this->display();
  }

3.html benötigt nur

  <p class="panel-body center">
           {$page}
