【代码】PHP 分页类
下面是我自己写的分页类,可做简单的修改
[php]
get = (int)$_GET['startRow'];
$this->post = (int)$_POST['pageNums'];
$this->pageSize = $pageSize;
$this->pageTotal = ceil($total / $pageSize);
switch ($_GET['method']){
default:
$this->startRow = 1;
$this->offset = 0;
break;
case 'first':
$this->first();
break;
case 'previous':
$this->previous();
break;
case 'next':
$this->next();
break;
case 'last':
$this->last();
break;
}
}
/**
* 首页方法
*
*/
public function first(){
$this->startRow = 1;
$this->offset = ($this->startRow - 1) * $this->pageSize;
}
/**
* 上一页方法
*
*/
public function previous(){
$this->startRow = $this->get - 1;
if ($this->startRow startRow = 1;
}
$this->offset = ($this->startRow - 1) * $this->pageSize;
}
/**
* 下一页方法
*
*/
public function next(){
$this->startRow = $this->get + 1;
if ($this->startRow > $this->pageTotal) {
$this->startRow = $this->pageTotal;
}
$this->offset = ($this->startRow - 1) * $this->pageSize;
}
/**
* 最后页方法
*
*/
public function last(){
$this->startRow = $this->pageTotal;
$this->offset = ($this->startRow - 1) * $this->pageSize;
}
/**
* 下拉菜单翻页
*
* @return Int
*/
public function numPages(){
if ($this->post) {
$pageNums = "";
$this->startRow = $this->post;
$this->offset = ($this->post - 1) * $this->pageSize;
}
for ($i = 1; $i pageTotal;$i++){
if ($i != $this->post) {
$pageNums .= "";
}
}
return $pageNums;
}
/**
* 当前是第几页
*
* @return Int
*/
public function noncePage(){
if ($this->post) {
return $this->startRow = $this->post;
} else {
return $this->startRow = $this->startRow;
}
}
}


调用方法:
[php]
$total = $total->total();//总记录
$pageSize = 15;//每页显示的记录
$pager = new Pager($total,$pageSize);
if ($pager->post){$startRow = $pager->noncePage();}
$startRow = $pager->startRow;
$pager->numPages();
$article->query("SELECT * FROM `categories` as c,`articles` as n WHERE c.id = n.pid
ORDER BY n.id DESC LIMIT $pager->offset,$pageSize");
while ($article->fetchArray()) {
$article->data['content'] = mb_substr(strip_tags($article->data['content']),0,40,'utf-8');
$articleIndex[] = $article->data;
}
$article->free();
} else {
header("location:?act=login");
}
$view->view->assign('startRow',$startRow);//caption
$view->view->assign('total',$total);//caption
$view->view->assign('pageNums',$pager->numPages());//pageNums
$view->view->assign('noncePage',$pager->noncePage());//pageNums
$view->view->assign('pageTotal',$pager->pageTotal);//pageTotal
