一段代码求解
if(!defined('IN_DISCUZ')) {
exit('Access Denied');
}
$page=$_GET['page']?$_GET['page']:0;
$perpage = 30;

$start = ($page-1)*$perpage;

$mpurl= 'home.php?mod=auction&ac=inauction';
$perpages = array($perpage => ' selected');
$auclist=C::t('auction_inauctions')->fetch_all_by_sql('status=1 AND uid='.$_G['uid'].' AND ovtime>'.strtotime(date("Y-m-d H:i:s")),'ORDER BY inputtime desc',$start,$perpage);

$count=C::t('auction_inauctions')->fetch_all_by_sql('status=1 AND uid='.$_G['uid'].' AND ovtime $multipage = multi($count, $perpage, $page, $mpurl);
include template('home/auction_inauctions');
?>

请高手讲解下以上代码，能逐行讲解最好了，谢谢！

------解决方案--------------------
显示某一页的数据
每页30行，从数据库取得数据然后用一个template显示

------解决方案--------------------




if(!defined('IN_DISCUZ')) {

exit('Access Denied');//验证是不是在discuz内部运行,不是就提示这个

}

$page=$_GET['page']?$_GET['page']:0;//如果page有赋值就用赋值的值 没有就为0

$perpage = 30;//应该是每页显示的调试


$start = ($page-1)*$perpage;//开始取得位置


$mpurl= 'home.php?mod=auction&ac=inauction';

$perpages = array($perpage => ' selected');

$auclist=C::t('auction_inauctions')->fetch_all_by_sql('status=1 AND uid='.$_G['uid'].' AND ovtime>'.strtotime(date("Y-m-d H:i:s")),'ORDER BY inputtime desc',$start,$perpage);

//C是discuz数据库操作的静态类，t方法指定操作的表  fetch_all_by_sql加查询条件得到结果集

$count=C::t('auction_inauctions')->fetch_all_by_sql('status=1 AND uid='.$_G['uid'].' AND ovtime
$multipage = multi($count, $perpage, $page, $mpurl);//multi是discuz的分页函数

include template('home/auction_inauctions');//将结果分配到模板展现

?>

------解决方案--------------------
if(!defined('IN_DISCUZ')) {
exit('Access Denied');
} //如果未定义'IN_DISCUZ' 直接退出；
$page=$_GET['page']?$_GET['page']:0; //如果页面传过来的值存在，值就等于传过来的值，如果没有值就为0；
$perpage = 30; // 赋值就不必说了吧- -

$start = ($page-1)*$perpage; //同上；

$mpurl= 'home.php?mod=auction&ac=inauction'; //url地址么；
$perpages = array($perpage => ' selected');
$auclist=C::t('auction_inauctions')->fetch_all_by_sql('status=1 AND uid='.$_G['uid'].' AND ovtime>'.strtotime(date("Y-m-d H:i:s")),'ORDER BY inputtime desc',$start,$perpage); //查询出来数据放在$auclist里边；

$count=C::t('auction_inauctions')->fetch_all_by_sql('status=1 AND uid='.$_G['uid'].' AND ovtime $multipage = multi($count, $perpage, $page, $mpurl); //多页? multi这玩意是个函数吧
include template('home/auction_inauctions'); //显示页面么；
