Thinkphp5之Bootstrap自定义BootstrapDetailed分页插件的实现

首先，在此目录建立一个newcrm\thinkphp\library\think\paginator\driver\BootstrapDetailed.php文件，代码如下：

    {
        $html = '';

        foreach ($urls as $page => $url) {
            $html .= $this->getPageLinkWrapper($url, $page);
        }

        return $html;
    }

    /**

    protected function getPageLinkWrapper($url, $page)
    {
        if ($page == $this->currentPage()) {
            return $this->getActivePageWrapper($page);
        }

        return $this->getAvailablePageWrapper($url, $page);
    }
}

　　

其次，在需要调用的控制器类里面写后台方法：如下

public function semList(){

//分页查询方法：
//方法一：自定义BootstrapDetailed实现分页倒叙列表查询
//$semList = SemModel::name('sem')->order('create_time desc')->paginate(6,false,['type' => 'BootstrapDetailed',]);
//方法二：laypage实现分页倒叙列表查询
$nowpage=input('page',1);//获取post传来的页数，如果没有页数时，页数为1
$totalpage=ceil((model('sem')->count())/10);////$totalpage就是计算你要获取的最大页数，ceil 是向前取整，这里是设置为10条数据为1页（注意括号）//这里尽量简写了。

//下面注意加上 这句 limit(($nowpage-1)*10,10)，就是数据控制每页显示数据的条数，获取页数后乘以设置的条数，获取该页的10条（自己设置）数据
$semList=model('sem')->order('create_time desc')->limit(($nowpage-1)*10,10)->select();
$count = SemModel::count();
$this->assign("totalpage",$totalpage);
$this->assign('count',$count);
$this->assign('semList',$semList);
return $this->fetch('sem_list');

}

然后，在html页面显示分页代码

<!--显示分页按钮,事先要将bootstrap导入css和js-->
<div style="float: right;margin-right: 20%;">
<div class="row">
<div class="col-lg-12"></div>
<div class="col-lg-12">{$rateList->render()}</div></div>
<div class="col-lg-12"></div>
</div>

最后，引入boostrap的js和css

{load href="__STATIC__/lib/bootstrap/css/bootstrap.min.css"/}
