本文实例讲述了thinkPHP分页功能。分享给大家供大家参考，具体如下：
interfaceServiceInterFace：

StaticService静态服务类：

abstractAbProduct 抽象商品管理类：
errorNum;
switch($errorNum){
case0:
$data['status']=0;
$data['message']='收藏成功';
break;
case1:
$data['status']=1;
$data['message']='收藏失败';
break;
case2:
$data['status']=2;
$data['message']='已收藏';
break;
case3:
$data['status']=3;
$data['message']='未登陆';
break;
case4:
$data['status']=4;
$data['message']='缺少参数';
break;
default:
$data['status']=200;
$data['message']='未知错误';
}
return$data;
}


MemberModel会员模型：

}


ProductModel商品模型：
where($condition)->find();
}
/**

*/
publicfunctiongetProList($data=''){

ProductManage商品管理类：

$this->assign(get_defined_vars());
$this->display();
}
publicfunctioncancelCollect(){
$ids=field('ids');
$return=ProductManage::getInstance()->cancelProductCollect($ids);
exit(json_encode($return));
}
}


functions.php分页函数：
$v){
if($k!='page'){
$url[]=urlencode($k).'='.urlencode($v);
}
}
$url[]='page={page}';
$url='?'.implode('&',$url);
}
if($total<=$perpage)
return'';
$total=ceil($total/$perpage);
$pagecount=$total;
$total=($maxpage&&$total>$maxpage)?$maxpage:$total;
$page=intval($page);
if($page<1||$page>$total)
$page=1;
$pages='上一页';
if($page>4&&$page<=$total-4){
$mini=$page-3;
$maxi=$page+2;
}elseif($page<=4){
$mini=2;
$maxi=$total-2<7?$total-2:7;
}elseif($page>$total-4){
$mini=$total-7<3?2:$total-7;
$maxi=$total-2;
}
for($i=1;$i<=$total;$i++){
if($i!=$page){
$pages.=''.$i.'';
}else{
$pages.=''.$i.'';
}
if($maxi&&$i>=$maxi){
$i=$total-2;
$maxi=0;
}
if(($i==2or$total-2==$i)&&$total>10){
$pages.='';
}
if($mini&&$i>=2){
$i=$mini;
$mini=0;
}
}
$pages.='=$total?$total:$page+1,$url).'"rel="externalnofollow"title="下一页"class="page_next">下一页共'.$totalcount.
'条/'.
$total.'页0)window.location.href=\''.$url.'\'.replace(/\{page\}/,document.getElementById(\'pageno\').value);">
'; return$pages; }
希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
