php 实现文章上一页与下一页 代码,这是我要写一个小作品时用到了,今天把它拿出来各各位分享一下下,记得以前我总想法不明白怎么实现文章上下一页的做法,后来在一个BBS看到了原来是判断当前ID然后order by 或asc就可以简单的实现了.

function nextpage($fid,$tag,$bid){
  if('next' ==$tag){
   $sql ="select * from gx_news where id<$fid and menu_id='$bid' order by id desc";
  }elseif('prev' ==$tag){
   $sql ="select * from gx_news where id>$fid and menu_id='$bid' order by id asc";
  }
  $result =mysql_query($sql);
  if(!mysql_num_rows($result) ){
   echo('己经没有了!');
  }else{
   $rs =mysql_fetch_array($result);
   echo "<a href=news_page.php?id=".$rs[0].">".$rs['new_title']."</a>";
  }
 }

好了代码其实很容易的了我也不讲了只是给初学者看看文章上一页与下一页是怎么实现的喽.

会员卡积分查询代码,本人今天人公司写一个简单的会员查询的系统现在把一部份拿出来了.

<span id="jfcxtitle"></span>
         <form action="" method="post" enctype="multipart/form-data" >
          <label for="point">输入您的卡号：</label>
          <input name="point" type="text" id="point" value="请输入您的卡号"  onClick="this.value='';">
          <input language="javascript" onclick="if (typeof(Page_ClientValidate) == 'function') Page_ClientValidate(); " name="submit" id="" type="submit" tabIndex="3" value="确定查询" />
         </form><font color=red>
                                   <?php
                                     if( $_POST ){          
                     
           $value =addslashes(isset($_POST['point'])?$_POST['point']:'');
           
           if( empty($value) || !is_numeric( $value) ){
           
            echo '请入的卡号有误!';
           
           }else{
            
            $sql="select * from gx_integral where inte_card='$value' ";
            
            $result=mysql_query($sql) or die('Database error! plase call us');
            
            if (!mysql_num_rows( $result) ) {
            
             echo '对不起,你输入的卡号不存在,请检查是否正确';
             
            }else{
            
             $rs =mysql_fetch_object( $result );
             
             echo '你的目前的积分为:',$rs['inte_integral'];
             
             mysql_free_result($rs);
            }
           
           }
          }
         ?>
                                    </font>
        </div>
