thinkphp自定义分页类

先来看下这个分页的样式，没写css,确实丑

什么时候写样式再来上传下css吧。。。。。。

就是多一个页面跳转功能

先把这个代码贴一下

<?php

namespace Component;

class Page {

    private $total; //数据表中总记录数
    private $listRows; //每页显示行数
    private $limit;
    private $uri;
    private $pageNum; //页数
    private $config = array('header' => "个记录", "prev" => "上一页", "next" => "下一页", "first" => "首 页", "last" => "尾 页");
    private $listNum = 8;

    /*
     * $total 
     * $listRows
     */

    public function __construct($total, $listRows = 10, $pa = "") {
        $this->total = $total;
        $this->listRows = $listRows;
        $this->uri = $this->getUri($pa);
        $this->page = !empty($_GET["page"]) ? $_GET["page"] : 1;
        $this->pageNum = ceil($this->total / $this->listRows);
        $this->limit = $this->setLimit();
    }

    private function setLimit() {
        return "Limit " . ($this->page - 1) * $this->listRows . ", {$this->listRows}";
    }

    private function getUri($pa) {
        $url = $_SERVER["REQUEST_URI"] . (strpos($_SERVER["REQUEST_URI"], '?') ? '' : "?") . $pa;
        $parse = parse_url($url);



        if (isset($parse["query"])) {
            parse_str($parse['query'], $params);
            unset($params["page"]);
            $url = $parse['path'] . '?' . http_build_query($params);
        }

        return $url;
    }

    function __get($args) {
        if ($args == "limit")
            return $this->limit;
        else
            return null;
    }

    private function start() {
        if ($this->total == 0)
            return 0;
        else
            return ($this->page - 1) * $this->listRows + 1;
    }

    private function end() {
        return min($this->page * $this->listRows, $this->total);
    }

    private function first() {
        $html = "";
        if ($this->page == 1)
            $html.='';
        else
            $html.="  <a href='{$this->uri}&page=1'>{$this->config["first"]}</a>  ";

        return $html;
    }

    private function prev() {
        $html = "";
        if ($this->page == 1)
            $html.='';
        else
            $html.="  <a href='{$this->uri}&page=" . ($this->page - 1) . "'>{$this->config["prev"]}</a>  ";

        return $html;
    }

    private function pageList() {
        $linkPage = "";

        $inum = floor($this->listNum / 2);

        for ($i = $inum; $i >= 1; $i--) {
            $page = $this->page - $i;

            if ($page < 1)
                continue;

            $linkPage.=" <a href='{$this->uri}&page={$page}'>{$page}</a> ";
        }

        $linkPage.=" {$this->page} ";


        for ($i = 1; $i <= $inum; $i++) {
            $page = $this->page + $i;
            if ($page <= $this->pageNum)
                $linkPage.=" <a href='{$this->uri}&page={$page}'>{$page}</a> ";
            else
                break;
        }

        return $linkPage;
    }

    private function next() {
        $html = "";
        if ($this->page == $this->pageNum)
            $html.='';
        else
            $html.="  <a href='{$this->uri}&page=" . ($this->page + 1) . "'>{$this->config["next"]}</a>  ";

        return $html;
    }

    private function last() {
        $html = "";
        if ($this->page == $this->pageNum)
            $html.='';
        else
            $html.="  <a href='{$this->uri}&page=" . ($this->pageNum) . "'>{$this->config["last"]}</a>  ";

        return $html;
    }

    private function goPage() {
        return '  <input type="text" onkeydown="javascript:if(event.keyCode==13){var page=(this.value>' . $this->pageNum . ')?' . $this->pageNum . ':this.value;location=\'' . $this->uri . '&page=\'+page+\'\'}" value="' . $this->page . '" style="width:25px"><input type="button" value="GO" onclick="javascript:var page=(this.previousSibling.value>' . $this->pageNum . ')?' . $this->pageNum . ':this.previousSibling.value;location=\'' . $this->uri . '&page=\'+page+\'\'">  ';
    }

    function fpage($display = array(0, 1, 2, 3, 4, 5, 6, 7, 8)) {
        $html[0] = "  共有<b>{$this->total}</b>{$this->config["header"]}  ";
        $html[1] = "  每页显示<b>" . ($this->end() - $this->start() + 1) . "</b>条，本页<b>{$this->start()}-{$this->end()}</b>条  ";
        $html[2] = "  <b>{$this->page}/{$this->pageNum}</b>页  ";

        $html[3] = $this->first();
        $html[4] = $this->prev();
        $html[5] = $this->pageList();
        $html[6] = $this->next();
        $html[7] = $this->last();
        $html[8] = $this->goPage();
        $fpage = '';
        foreach ($display as $index) {
            $fpage.=$html[$index];
        }

        return $fpage;
    }

}

 我把这个文件放在了Component下面

然后在我们需要用到分页的地方

　　

$goods=D("Goods");
        //1.获取当前记录的总条数
        $total=$goods->count();
        //每页记录数
        $per=10;
        //2.实例化分页类对象
        $page=new \Component\Page($total,$per);
        //3.拼接sql语句
        $sql="select * from sw_goods ".$page->limit;
　　　　　//查询数据
        $info=$goods->query($sql);
        //获得页码列表 调用的分页类的fpage（）方法
        $pagelist=$page->fpage();
　　　　　
　　　　
　　　　　//数据信息
        $this->assign("info",$info);
　　　　 //分页信息
        $this->assign("pagelist",$pagelist);
        $this->display();

 然后在要显示的地方用上

{$pagelist}
