分页模块,自己再改改样式即可

下面来介绍用法:
$Configuration = array(
'total' => 30, //总条数
'traction' => 3, //当前页面需要显示的条数
'url' => './StudentManagement', //分页按钮的url地址
);
//调用分页模块,第一个参数是将页面获取的数据传递进去,$_REQUEST全局变量,POST或者GET的都可以获取大。第二个参数就是上面的数组,配置参数
$PageingObj = new PagingModel($_REQUEST, $Configuration);
$this->assign('pageing', $PageingObj->GetPagingHtmlInfo()); //然后就调用这个方法返回分页代码,放在页面上去就可以了
