这篇文章主要介绍了thinkPHP3.2.3结合Laypage实现的分页功能,结合实例形式分析了thinkPHP3.2.3结合Laypage实现分页的model控制器与view视图相关操作技巧,需要的朋友可以参考下

本文实例讲述了thinkPHP3.2.3结合Laypage实现的分页功能。分享给大家供大家参考，具体如下：

控制器

<?php
namespace Home\Controller;
use Think\Controller;
class IndexController extends Controller {
  /**
  *@brief 查询
  ****/
  public function index(){
  $choose = I(&#39;choose&#39;,&#39;-6&#39;);
  $c[&#39;easy_hard&#39;] = $choose;
    $type=I(&#39;typeid&#39;,&#39;&#39;);
    $nowpage=I(&#39;page&#39;,1);
    if($type == &#39;&#39;)
    {
      if($choose == -6)
      {
        $totalpage=ceil((D(&#39;data&#39;)->count())/10);
        $infos=D(&#39;data&#39;)->limit(($nowpage-1)*10,10)->select();
      }else{
        $totalpage=ceil((D(&#39;data&#39;)->where($c)->count())/10);
        $infos=D(&#39;data&#39;)->where($c)->limit(($nowpage-1)*10,10)->select();
      }
    }else{
      if($choose == -6)
      {
        $map[&#39;data&#39;] = array(&#39;like&#39;,"%$type%");
        $totalpage=ceil((D(&#39;data&#39;)->where($map)->count())/10);
        $infos=D(&#39;data&#39;)->where($map)->limit(($nowpage-1)*10,10)->select();
      }else{
        $map[&#39;data&#39;] = array(&#39;like&#39;,"%$type%");
        $totalpage=ceil((D(&#39;data&#39;)->where($map)->where($c)->count())/10);
        $infos=D(&#39;data&#39;)->where($map)->where($c)->limit(($nowpage-1)*10,10)->select();
      }
    }
  $this->assign(&#39;type&#39;,$type);
    $this->assign(&#39;choose&#39;,$choose);
    $this->assign("totalpage",$totalpage);
    $this->assign("infos",$infos);
    $this -> display();
  }
}
