thinkphp 3.2分页 自定义分页函数

1.先将自定义函数放于（适用于3.2版本）



2.该自定义函数为代码如下

<?php

namespace Org\Util;

class UserPage{
private $each_disNums;
private $nums;
private $current_page;//当前被选中的页
private $sub_pages;//每次显示的页数
private $pageNums;//总页数
private $page_array = array();//用来构造分页的数组
private $subPage_link;//每个分页的链接

function __construct($each_disNums,$nums,$current_page,$sub_pages,$subPage_link,$subPage_type){
$this->each_disNums=intval($each_disNums);
$this->nums=intval($nums);
if(!$current_page){
$this->current_page=1;
}else{
$this->current_page=intval($current_page);
}
$this->sub_pages=intval($sub_pages);
$this->pageNums=ceil($nums/$each_disNums);
$this->subPage_link=$subPage_link;

//$return_str = $this->show_SubPages($subPage_type);

//echo $this->pageNums."--".$this->sub_pages;
}
function __destruct(){
unset($each_disNums);
unset($nums);
unset($current_page);
unset($sub_pages);
unset($pageNums);
unset($page_array);
unset($subPage_link);
unset($subPage_type);
}

/*
show_SubPages函数用在构造函数里面。而且用来判断显示什么样子的分页
*/
function show_SubPages($subPage_type){
if($subPage_type == 1){

$this->subPageCss1();
}elseif ($subPage_type == 2){

return($this->subPageCss2());
}
}

/*
用来给建立分页的数组初始化的函数。
*/
function initArray(){
for($i=0;$i<$this->sub_pages;$i++){
$this->page_array[$i]=$i;
}
return $this->page_array;
}

/*
construct_num_Page该函数使用来构造显示的条目
即使：[1][2][3][4][5][6][7][8][9][10]
*/
function construct_num_Page(){
if($this->pageNums < $this->sub_pages){
$current_array=array();
for($i=0;$i<$this->pageNums;$i++){
$current_array[$i]=$i+1;
}
}else{
$current_array=$this->initArray();
if($this->current_page <= 3){
for($i=0;$i<count($current_array);$i++){
$current_array[$i]=$i+1;
}
}elseif ($this->current_page <= $this->pageNums && $this->current_page > $this->pageNums - $this->sub_pages + 1 ){
for($i=0;$i<count($current_array);$i++){
$current_array[$i]=($this->pageNums)-($this->sub_pages)+1+$i;
}
}else{
for($i=0;$i<count($current_array);$i++){
$current_array[$i]=$this->current_page-2+$i;
}
}
}

return $current_array;
}

/*
构造普通模式的分页
共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页]
*/
function subPageCss1(){
$subPageCss1Str="";
$subPageCss1Str.="共".$this->nums."条记录，";
$subPageCss1Str.="每页显示".$this->each_disNums."条，";
$subPageCss1Str.="当前第".$this->current_page."/".$this->pageNums."页 ";
if($this->current_page > 1){
$firstPageUrl=$this->subPage_link."1";
$prewPageUrl=$this->subPage_link.($this->current_page-1);
$subPageCss1Str.="<a href='$firstPageUrl'>首页</a> ";
$subPageCss1Str.="<a href='$prewPageUrl'>上一页</a> ";
}else {
$subPageCss1Str.="首页 ";
$subPageCss1Str.="上一页";
}

if($this->current_page < $this->pageNums){
$lastPageUrl=$this->subPage_link.$this->pageNums;
$nextPageUrl=$this->subPage_link.($this->current_page+1);
$subPageCss1Str.=" <a href='$nextPageUrl'>下一页</a>";
$subPageCss1Str.="<a href='$lastPageUrl'>尾页</a>";
}else {
$subPageCss1Str.="下一页";
$subPageCss1Str.="尾页";
}

return $subPageCss1Str;

}

/*
构造经典模式的分页
当前第1/453页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页]
*/
function subPageCss2(){
$subPageCss2Str="";
//        $subPageCss2Str.="当前第".$this->current_page."/".$this->pageNums."页 ";

if($this->current_page > 1){
$firstPageUrl=$this->subPage_link."1".".html";
$prewPageUrl=$this->subPage_link.($this->current_page-1).".html";
$subPageCss2Str.="<a href='$firstPageUrl'>首页</a>";
$subPageCss2Str.="<a href='$prewPageUrl'>上一页</a>";
}else {
$subPageCss2Str.="首页 ";
$subPageCss2Str.="上一页 ";
}

$a=$this->construct_num_Page();
for($i=0;$i<count($a);$i++){
$s=$a[$i];
if($s == $this->current_page ){
$subPageCss2Str.= "<span style='color:#ffffff;font-weight:bold;'>" .$s."</span>";
}else{
$url=$this->subPage_link.$s.".html";
$subPageCss2Str.="<a href='$url'>".$s."</a>";
}
}

if($this->current_page < $this->pageNums){
$lastPageUrl=$this->subPage_link.$this->pageNums.".html";
$nextPageUrl=$this->subPage_link.($this->current_page+1).".html";
$subPageCss2Str.="<a href='$nextPageUrl'>下一页</a> ";
$subPageCss2Str.="<a href='$lastPageUrl'>尾页</a>";
}else {
$subPageCss2Str.="下一页 ";
$subPageCss2Str.="尾页 ";
}
return $subPageCss2Str;
}
}

3.在控制器里引用改函数
$subPages = new \Org\Util\UserPage($pagesize, $nums, $pageCurrent, $sub_pages,$next_url);
<div id="pages">
{$page}
</div>
4.前台页面显示
$pageStr = $subPages->show_SubPages(2);
$this->assign('page',$pageStr);
