各位老师,帮我看看能不能改成支持可分页。
include("Conn/conn.php");
$query=mysql_query("select book.barcode,book.id as bookid,book.bookname,bt.typename,pb.pubname,bc.name from tb_bookinfo book join tb_booktype bt on book.typeid=bt.id join tb_publishing pb on book.ISBN=pb.ISBN join tb_bookcase bc on book.bookcase=bc.id");
$result=mysql_fetch_array($query);
  if($result==false){
?> 
 


 
 
 
 
暂无图书信息!

 
 
 
 

  添加图书信息

 }else{
?>
 
 
 
 
 
 
  添加图书信息
 
 
 
   
 
 
 
 
 
 
 

 
   
 
   
   
   
 
 
 

  }while($result=mysql_fetch_array($query));
}
?>

------解决方案--------------------
可以改,改的代码有点多,从头改到尾,理清头绪难度不大
1:分页标识与两个参数卡定 url?startPostion=0&number=10
startPostion开始位置,number一次条数
2:查询条件
$sqlString="select * from myTable1 where 1 limit $startPos,$num";
//明白这句话就实现了一半
3:底下生成页数前一页与后一页与对应的链接
明白后都是体力活了

我表达清楚了没?



------解决方案--------------------
分页其实弄清楚
1、当前第几页
2、每页显示数
就可以了

通过上面2个条件,写sql语句。
