thinkphp5 原生sql带分页方法

1、先在顶部引入use think\paginator\driver\Page;

2、使用下例代码

        $pageNumber = input('page')? input('page'):'0';//客户端传过来的分页
        if($pageNumber > 0){
            $pageNumber_one = $pageNumber-1;
        }else{
            $pageNumber_one = 0;
        }
        $limit = 20;//每页显示条数;
        $offset= $pageNumber_one*$limit;//查询偏移值//查询数
        $list = Db::query("SELECT * FROM `表名` LIMIT $offset,$limit ");
        $count_data = Db::query('SELECT count(*) FROM `表名` ');
        $count = $count_data['0']['count(*)'];//组合分页数据格式
        $this->assign('count',$count);
        //组合分页数据格式
        $pagernator = Page::make($list,$limit,$pageNumber,$count,false,['path'=>Page::getCurrentPath(),'query'=>request()->param()]);
        $this->assign('datalist',$list);
        $this->assign('page',$pagernator->render());

3、think\paginator\driver\Page.php的代码如下

 

<?php

namespace think\paginator\driver;

use think\Paginator;

class Page extends Paginator
{
    //首页
    protected function home($text = "首页") {
        if ($this->currentPage() <= 1) {
            return $this->getDisabledTextWrapper($text);
        }

        $url = $this->url(1);

        return $this->getPageLinkWrapper($url, $text);
    }

    /**
     * 上一页按钮
     * @param string $text
     * @return string
     */
    protected function getPreviousButton($text = "上一页")
    {

        if ($this->currentPage() <= 1) {
            return $this->getDisabledTextWrapper($text);
        }

        $url = $this->url($this->currentPage() - 1);

        return $this->getPageLinkWrapper($url, $text);

    }
    /**
     * 下一页按钮
     * @param string $text
     * @return string
     */
    protected function getNextButton($text = '下一页')
    {
        if (!$this->hasMore) {
            return $this->getDisabledTextWrapper($text);
        }

        $url = $this->url($this->currentPage() + 1);

        return $this->getPageLinkWrapper($url, $text);
    }
    //尾页
    protected function last($text = '尾页') {
        if (!$this->hasMore) {
            return $this->getDisabledTextWrapper($text);
        }

        $url = $this->url($this->lastPage);

        return $this->getPageLinkWrapper($url, $text);
    }
    /**
     * 页码按钮
     * @return string
     */
    protected function getLinks()
    {
        if ($this->simple)

        } elseif ($this->currentPage <= $window) {
            $block['first'] = $this->getUrlRange(1, $window + 2);
            $block['last']  = $this->getUrlRange($this->lastPage - 1, $this->lastPage);
        } elseif ($this->currentPage > ($this->lastPage - $window)) {

4、分页按钮样式

.pagination span{
    margin:0;
    cursor:pointer
}
.pagination{
    padding:0;
    margin:20px 0;text-align: center;
}
.pagination a{
    margin-right:10px;
    padding:6px 12px;
    border:1px #cccccc solid;
    background:#fff;
    text-decoration:none;
    color:#808080;
    font-size:12px;
    line-height:24px;
}
.pagination a:hover{
    color:#fc6d41;
    background: white;
    border:1px #fc6d41 solid;
}
.pagination a.cur{
    border:1px #fc6d41 solid;
    background:#fc6d41;
    color:#fff;padding:6px 12px;
}
.pagination span{
    padding:6px 12px;
    font-size:12px;
    line-height:24px;
    color:#bbb;
    border:1px #ccc solid;
    background:#fcfcfc;
    margin-right:8px;

}
.pagination span.pageRemark{
    border-style:none;
    background:none;
    margin-right:0px;
    padding:4px 0px;
    color:#666;
}
.pagination span.pageRemark b{
    color:red;
}
.pagination span.pageEllipsis{
    border-style:none;
    background:none;
    padding:4px 0px;
    color:#808080;
}
