以前寫過很多php 分頁類但是今天這款分頁程序我感覺是很好的,簡(jiǎn)潔實(shí)用,代碼合理并沒有多余的代碼,是一款不錯(cuò)分頁類函數(shù)哦。
- class multipage {
- var $total;
- var $perpage;
- var $pages;
- var $maxpage;
- var $offset = 9;
- var $curr_page;
- function init($total, $perpage, $maxpage) { //初始化頁數(shù)
- $this->total;
- $this->perpage;
- $this->maxpage;
- $this->offset = 9;
- }
- function getpagelist() {//獲取分頁列表
- $result_pages = "";
- $this->pages = ceil($this->total / $this->perpage);
- if ($this->pages > $this->maxpage) {
- $from = $this->curr_page - $this->offset;
- if ($from < 1) {
- $from = 1;
- }
- $to = $from + $this->maxpage - 1;
- if ($to > $this->pages) {
- $to = $this->pages;
- if (($to - $from) < $this->maxpage) {
- $from = $from - 1;
- }
- }
- } else {
- $from = 1;
- $to = $this->pages;
- }
- $p = 0;
- for($i = $from; $i <= $to; $i++) {
- $result_pages[$p] = $i;
- $p++;
- }
- return $result_pages;
- }
- function getfirst() { //獲取第一頁
- if ($this->curr_page > 1 && $this->pages > 1) {
- return 1;
- } else {
- return "";
- }
- }
- function getlast() { //取末頁
- if ($this->pages > 1 && $this->curr_page < $this->pages) {
- return $this->pages;
- } else {
- return "";
- }
- }
- function getprev() {//上一頁
- $prevpage = $this->curr_page - 1;
- if ($prevpage > 0) {
- return $prevpage;
- } else {
- $prevpage = "";
- return $prevpage;
- }
- }
- function getnext() {//下一頁
- $nextpage = $this->curr_page + 1;
- if ($nextpage <= $this->pages) {
- return $nextpage;
- } else {
- $nextpage = "";
- return $nextpage;
- }
- }
- function gettotal() {//共多少頁
- if ($this->pages > 0) {
- return $this->pages;
- } else {
- return 1;
- }
- }
- }
- //分頁類的使用方法
- $page = new multipage();
- $page->gettotal(); //總頁婁
- $page->getnext();//下一頁
